Getting Started with Ajax Developer

This document covers the following topics:


About the Runtime Environment

Ajax Developer requires a web container such as Tomcat as its runtime environment.

If NaturalONE is installed, an Apache Tomcat is already included and all required configuration has automatically been done. In this case, you can immediately enable a project for Ajax Developer (see below).

If NaturalONE is not installed, you must first enter the settings for your own local web container environment in the Ajax Developer preferences. For further information, see Setting the Ajax Developer Preferences.

Setting the Ajax Developer Preferences

The web application configuration in the Ajax Developer preferences is normally only required if you use your own local web container environment, that is, when NaturalONE is not installed.

Start of instruction setTo set the Ajax Developer preferences

  1. From the Window menu, choose Preferences.

  2. In the tree of the resulting dialog box, expand the Software AG node and then select the Ajax Developer node.

  3. If you want to use your own web container environment, choose the Custom tab on the resulting Ajax Developer page and specify all required information. For information on the available options, see Enabling a Project for Ajax Developer.

    It is important that you set the web application folder to <webcontainerinstalldir>/webapps/cis. Example:

    Preferences

  4. The options under Layout display mode allow you to control how the page layouts are rendered by default in the Layout Painter preview window. If you choose SWT, the layout will be rendered by default as SWT (Standard Widget Toolkit) pages, that is, with Java means. If you choose HTML, the layout will be rendered by default as HTML pages.

    Note:
    You can also change the display mode directly in the Layout Painter, using a menu command. See Changing the Display Mode.

  5. The options under Layout refresh mode allow you to enable or disable automatic refreshing of the Layout Painter's preview area.

  6. The options under Layout direction allow you to design your page layout in either left-to-right (LTR) or right-to-left (RTL) direction. The specified direction is then used in the preview area of the Layout Painter.

  7. Choose the OK button to save your changes and to close the dialog box.

Working with Projects

The following topics are covered below:

Types of Projects

With Ajax Developer, page layouts can be developed in Natural or Java projects. You create your Natural or Java project as usual and then enable this project for Ajax Developer. When a project has been enabled for Ajax Developer, the settings for a specific web container environment are applied to the project. These settings are used to develop and run page layouts.

You can have multiple projects which are enabled for different web container environments.

In a NaturalONE installation, you will usually always enable a project for the preconfigured Tomcat environment. This is the so-called "Development" environment which is automatically installed and configured with NaturalONE.

When NaturalONE is not installed, you have the following choices for the location of your Java projects:

Enabling a Project for Ajax Developer

Before you can define layout pages for a project, you have to enable the project for Ajax Developer.

Start of instruction setTo enable a project for Ajax Developer

  1. In the Navigator view, select the project that you want to enable.

  2. Invoke the context menu and choose Enable for Ajax Developer.

    The following dialog box appears:

    Enable project

  3. Specify the following information:

    Web applications

    Select one of the following options from the drop-down list box:

    • Development
      If NaturalONE is installed, select this option. No further steps are required (the configuration options in this dialog box are disabled in this case).

      Note:
      This option is only available when NaturalONE is installed.

    • Custom
      If NaturalONE is not installed, select this option. In this case, the configuration options in the dialog box are enabled and you can define your own settings for your web container environment. See below.

    Web server folder

    The root folder of the local web container environment.

    Web server connection

    Host name and port number of the local web container environment.

    Web application folder

    The folder of the Application Designer web application. For NaturalONE installations, this is the root folder of the cisnatural web application. If NaturalONE is not installed, this is the root folder of the cis web application (<webcontainerinstalldir>/webapps/cis).

    Web application name

    For NaturalONE, this is cisnatural. If NaturalONE is not installed, this is cis.

    Layout display mode

    Select the display mode for the Layout Painter and Layout Tester:

    • HTML
      This mode makes use of the ActiveX plug-in of Eclipse in which Internet Explorer is running.

    • SWT
      This mode makes use of SWT controls which are shown in an SWT client.

    Layout refresh mode

    Enable or disable automatic refreshing of the Layout Painter's preview area:

    • Off
      The preview area is not automatically refreshed when the layout is changed. It is only refreshed when the changes are saved. It is recommended that you use this mode if you are working with complex controls such as ROWTABAREA.

    • On
      The preview area is automatically refreshed when the layout changes, even if the changes have not yet been saved.

    Create root folder

    When selected, all user interface components of the project are created within a folder which has the fixed name "User-Interface-Components".

    When not selected, all user interface components of the project are created directly in the project directory.

    When NaturalONE is installed, the default for this setting can be defined under Window > Preferences > Software AG > Natural.

    Use workspace relative paths

    This option is read-only.

    In a NaturalONE installation, the Development web application is part of your Eclipse workspace. Ajax Developer automatically uses relative paths to access this web application. When relative paths are used, the workspace can be renamed or moved on the file system.

    If you are not working with NaturalONE and you are using the Custom web application, the web application is usually not located within your Eclipse workspace. In this case, Ajax Developer uses absolute paths. If you move your web application or your Tomcat on the file system, you must adapt the settings.

  4. Choose the Finish button.

    The icon for the project changes to indicate that Ajax Developer has been enabled for the project.

    The context menu for the project now provides the additional cascading menu Ajax Developer which provides for selection a number of tools which are helpful when defining layouts.

Changing the Ajax Developer Properties for a Project

If you are working with NaturalONE, you can change the layout display mode that is defined for the project, for example, from SWT mode to HTML mode. If NaturalONE is not installed, you can also change the settings for your web container environment.

Start of instruction setTo change the properties

  1. In the Navigator view or in the Natural Navigator view, select the project which has been enabled for Ajax Developer.

  2. Invoke the context menu and choose Properties.

  3. In the tree of the resulting dialog box, select Ajax Developer.

    The resulting page contains the same information as the dialog box which appears when you enable a project for Ajax Developer. See Enabling a Project for Ajax Developer for further information.

Disabling a Project for Ajax Developer

If you decided to remove all user interface components from a project, it makes sense to entirely disable this project for Ajax Developer. Then, the Ajax Developer functionality is no longer available for the project.

The user interface components are not deleted physically from the disk. Thus, it is possible to re-enable the same project for Ajax Developer later.

Start of instruction setTo disable a project

  1. In the Navigator view, select the project that you want to disable.

  2. Invoke the context menu and choose Ajax Developer > Disable.

Working with User Interface Components

The following topics are covered below:

Creating User Interface Components

After a project has been enabled for Ajax Developer, you can add user interface components. A user interface component is a container for a set of layout pages and additional artifacts such style sheets, images or language files.

A user interface component is also connected to the corresponding Natural or Java sources which implement the business logic. A single Java or Natural project may contain several user interface components.

The name of the user interface component must be unique across the Eclipse workspace.

Start of instruction setTo create a user interface component

  1. In the Navigator view or in the Natural Navigator view, select the project in which you want to create a user interface component.

  2. From the File menu or context menu, choose New > User Interface Component.

    The following dialog box appears:

    graphics/ad-newui1.png

  3. In the Component name text box, enter a name for your user interface component (for example "MyFirstUI").

  4. Select one of the following option buttons:

    Create new user interface component

    This option creates a new user interface component from scratch. The location of the new user interface component is a subfolder of your Natural or Java project folder.

    Enable a folder as user interface component

    This option converts an existing subfolder of the project to a user interface component folder. In this case, you have to choose the Browse button to select the folder to be converted from a dialog box.

    The internal web container environment is then used for further development.

    Import user interface component from internal server

    This option moves an existing Application Designer project from the internal web container environment to your Eclipse workspace. The internal web container environment is the environment configured for this Natural or Java project. In this case, you have to select a component from the Existing components drop-down list box.

    In a NaturalONE environment, the components "njxdemos" and "njxmapconverter" are provided in the drop-down list box.

    If NaturalONE is not installed, the component "cisdemos" is provided, and any existing Application Designer projects in your cis web application. If you have chosen the cis web application folder as your project location, the selected Application Designer projects will not be moved. If you have chosen a different project location, the selected Application Designer projects will be physically moved to a subfolder of your Java project folder.

    Import user interface component from external server

    This option copies an existing Application Designer project from an external web container environment to your Eclipse workspace. An external web container environment is an environment other than the environment which is configured for the Natural or Java project. In this case, you have to choose the Browse button to select an external component from a dialog box.

    The internal web container environment is then used for further development. The original sources in the external web container environment are no longer updated.

  5. Choose the Next button.

    The following page appears:

    graphics/ad-newui2.png

  6. Choose the Browse button to select from a dialog box the folder into which the adapters are to be generated. Usually, you will select the SRC folder of a Natural library.

  7. The Name validation text box shows all regular expressions that are used for the validation of properties and methods.

    To switch off the validation, select the Disable name validation check box.

  8. Select either the Left to right or Right to left option button. The specified layout direction is then used in the preview area of the Layout Painter. The selected layout direction applies for all layouts in this user interface component.

    Note:
    The default layout direction for new user interface components is specified in the Ajax Developer preferences.

  9. Choose the Finish button.

    A new folder with the component name that you have defined is now shown in the Navigator view or Natural Navigator view.

File Structure in a User Interface Component

After the creation of a user interface component, the following folders are visible in the Navigator view:

Folder Name Description
xml Contains the page layouts.
multilanguage Contains text files for the language support. These files are maintained with the Literal Translator.

In addition, a user interface component contains folders such as accesspath, wsdl or protocol. These folders contain generation results which are automatically changed when a layout is modified. The files in these folders are not intended to be viewed or modified directly, and are therefore filtered in the Navigator view.

Changing the Properties of a User Interface Component

In the properties of a user interface component, you can change the path to the Natural adapter folder, you can change the regular expressions that are used for the validation of properties and methods, you can disable the name validation, or you can change the layout direction.

Start of instruction setTo change the properties of a user interface component

  1. Select the user interface component in the Navigator view or in the Natural Navigator view.

  2. Invoke the context menu and choose Properties.

  3. In the tree of the resulting dialog box, expand the Ajax Developer node.

    This displays the same information which is also shown on the second page when you create a user interface component.

    Properties

  4. Change all required information.

  5. Choose the OK button to save your changes and to close the dialog box.

Exporting User Interface Components

You can export a user interface component to an external web container environment. This is useful if a user interface component is to be tested in an environment other than the development environment.

Start of instruction setTo export a user interface component

  1. In the Navigator view, select the user interface component that you want to export

  2. Invoke the context menu and choose Ajax Developer > Export.

    The standard Eclipse functionality for exporting to the file system is used; see the Eclipse online help for further information.

  3. Specify all required information.

  4. Choose the Finish button.

Removing User Interface Components

When a user interface component is no longer required, you can remove it from the internal server.

After removing a user interface component, the files still exist physically on the disc and are still accessible in the Navigator view or Natural Navigator view, but the files are no longer accessible from within the web application. If you also want to delete the files, use the Delete command which is available in the context menu.

Start of instruction setTo remove a user interface component

  1. In the Navigator view, select the user interface component that you want to remove.

  2. Invoke the context menu and choose Ajax Developer > Remove.

    A dialog appears, indicating that the user interface component has been removed from the web application.

Cleaning User Interface Components

When you clean a user interface component, files such as *.html, *.access and *.NS8, which have been generated for the layouts in the selected user interface component, are removed.

Start of instruction setTo clean a user interface component

  1. In the Navigator view, select the user interface component that you want to clean.

  2. Invoke the context menu and choose Ajax Developer > Clean.

Building User Interface Components

When you build a user interface component, HTML files are generated for the XML layout definitions. For pages of type NATPAGE, the adapters (*.NS8 files) are also generated. This is helpful, for example, if you have previously cleaned the user interface component.

When an HTML file does not exist, it is generated. When an HTML file already exists, it is regenerated using the latest information from the XML layout definition.

Note:
When you save a layout with the Layout Painter for the first time, an HTML file is automatically generated (in addition to the XML file).

Start of instruction setTo build a user interface component

  1. In the Navigator view, select the user interface component that you want to build.

  2. Invoke the context menu and choose Ajax Developer > Build.

Refreshing User Interface Components

In rare situations, it may happen that the configuration files of the web application are not in sync with the existing user interface components in your project. This may happen, for example, when a user interface component is created in a new workspace before the initialization of the Development web application is finished.

In these cases, you can refresh the user interface components to synchronize the configuration files of the web application with the user interface components. If the user interface components are already in sync, the commands described below will not apply any changes.

Start of instruction setTo refresh all user interface components in a project

  1. In the Navigator view, select the project in which you want to refresh the user interface components.

  2. Invoke the context menu and choose Ajax Developer > Refresh User Interface Components.

Start of instruction setTo refresh a single user interface component

  1. In the Navigator view, select the user interface component that you want to refresh.

  2. Invoke the context menu and choose Ajax Developer > Refresh.

Executing and Debugging User Interface Components

You can execute pages of type PAGE and MFPAGE (workplace). Execution means that the page with the real application (Natural or Java) is started in the browser.

For workplace applications (MFPAGE) which contain pages implemented with Natural, you can debug the corresponding Natural programs.

For NaturalONE, see also Executing and Debugging Workplace Applications in the Natural for Ajax documentation that is provided for NaturalONE.

Start of instruction setTo execute a page

  1. In the Navigator view, select a page of type PAGE or MFPAGE.

  2. Invoke the context menu and choose Ajax Developer > Execute.

Start of instruction setTo debug Natural programs in a workplace application (MFPAGE)

  1. In the Navigator view, select a page of type MFPAGE.

  2. Invoke the context menu and choose Ajax Developer > Debug.

Notes:

  1. For pages of type MFPAGE, the Debug command is only enabled when the debug attach server has been enabled in the Natural preferences. See also Setting the Preferences in Using NaturalONE, which is part of the NaturalONE documentation.
  2. The commands Execute and Debug are only available for the above mentioned page types. For pages of type NATPAGE, you have to start the application by executing or debugging the corresponding Natural main program. See also Executing the Main Program and Debugging the Main Program in the Natural for Ajax documentation that is provided for NaturalONE.

Working With Version Control Systems

Eclipse provides fully integrated support for version control systems such as CVS or Subversion (SVN) via corresponding plug-ins.

The following topics are covered below:

Checking In Projects and User Interface Components

You have to check in the following Ajax Developer-specific files and folders of a project:

Do not check in the following files and folders (you can see them, for example, when you switch to the Resource perspective):

To ignore the first two file categories listed above, you can either add them to .cvsignore or svn:ignore (depending on the version control system you are using), or you can simply clean the user interface component before you synchronize with your repository.

Checking Out Projects and User Interface Components

If you have checked in all files and folders described above, you can simply check out the project, including the user interface components, into a new workspace. The user interface components are automatically added to the internal Tomcat of this workspace.

After a check-out, it is recommended that you rebuild the project using the Clean command from the Project menu. If the Build Automatically command in the Project menu is currently not active, make sure that Start a build immediately is switched on in the Clean dialog box.

Using the Ajax Developer Perspective

Ajax Developer provides its own perspective which contains the views which are important for editing layouts. The positions and sizes of the views are optimized for developing and testing the layout pages.

Note:
When NaturalONE is installed, it is not mandatory to use the Ajax Developer perspective. You can also use the NaturalONE perspective. However, with the Ajax Developer perspective, the Properties view for modifying the properties of a page layout, for example, is shown with a convenient size and position.

Start of instruction setTo open the Ajax Developer perspective

Developing Java Extensions

For some advanced functionality such as writing adapter listeners, advanced custom controls or advanced workplace enhancements, the development of Java extensions is supported.

If you want to develop Java extensions in NaturalONE, proceed as follows:

Note:
The folder cisnatural is located in your Eclipse workspace under \.naturalone\apache-tomcat\webapps.
