Step 1: Start the IDL Extractor for Integration Server

To start the IDL Extractor for Integration Server

1. The IDL Extractor is a New Wizard in Eclipse. Choose New from the file menu, select IDL Extractor for webMethods IS in the following page and choose Next.

   Note:
   You can also choose New from the toolbar or context menu of a view showing resources. Also Ctrl-N starts the selection of the New Wizards.

2. If you are using the wizard for the first time without any predefined Integration Server connections, continue with Step 2a: Connect Designer with Integration Server.

   Or:
   If Integration Server connections are already defined (see Integration Server Connections), or you want to communicate with an additional Integration Server, continue with Step 2b: Connect Designer with Integration Server using an Existing Connection.

Step 2a: Connect Designer with Integration Server

To create a new Integration Server connection

1. Define the new Integration Server connection on the following wizard page.

   Notes:

   1. The only required field is Server. Enter the hostname of the Integration Server including an optional port number. If no port number is specified, port number defaults to "5555". The Integration Server Authentication can be passed with the User and Password fields.
   2. Optional settings are for secure connections. The Truststore for HTTPS contains all signed certificates and must be a valid truststore.
   3. The check box Verify host name checks that the hostname is entered in the stored certificate.
   4. When the Integration Server has Client Authentication enabled, you can specify your Keystore file and keystore Password.
   5. For managing Integration Server connections, see Integration Server Preferences in the Integration Server Wrapper documentation.

   

2. Choose Next and continue with Step 3: Select the Integration Server Package to Extract.

Step 2b: Connect Designer with Integration Server using an Existing Connection

To use an existing Integration Server connection

1. Select Choose an existing Integration Server Connection and an Integration Server connection from the list.

   The selected connection is verified by a ping command. If the response is valid, the Next button is enabled. If invalid, an error message is displayed.

2. Continue with Step 3: Select the Integration Server Package to Extract.

To create an additional Integration Server connection

1. Select Create a new Integration Server Connection and continue with Step 2a: Connect Designer with Integration Server.

Step 3: Select the Integration Server Package to Extract

To extract the IDL from the selected package

1. Select the package to extract (from the list indicated by Source), for example the package "Default" in the screen above.

2. Specify the target. By default, the wizard tries to find a valid container based on your position in the Navigator or Package Explorer View.

   Or:
   Choose Browse... to select a container from your workspace.

   Notes:

   1. The IDL file name is based on the selected Integration Server package from the list below, but this is only a proposal and can be changed.
   2. If the file name already exists in your container, a warning will be displayed in the title area of the wizard page.
   3. If the extension "idl" is not specified, it will be added automatically.

3. Optimize the extracted IDL. Use the combo-box and select the target programming language:

   • COBOL
     For usage with the COBOL Wrapper. Enter the default length for IDL type A(default-length) fields which map then to COBOL alphanumeric data items PIC X(default-length).

   • Natural
     For usage with the Natural Wrapper. Choose one option indicated by Map Integration Server data type to IDL:

     • alphanumeric with variable length: Extract to IDL Type AV fields which map then to Natural DYNAMIC data types. The interface does not have any length restrictions.

     • alphanumeric with fixed length: Extract to IDL Type A(default-length) fields which map then to Natural fixed-length alphanumeric data types. The interface from a Natural point of view is more legacy-like and easier to program, but there are length restrictions.

   • PL/I
     For usage with the PL/I Wrapper. Enter the default length for IDL Type A(default-length) fields which map then to PL/I fixed-length alphanumeric fields CHAR (default-length).

   • Other
     For usage with other EntireX Wrappers. If you later use wrappers other than the COBOL Wrapper, Natural Wrapper or PL/I Wrapper, no options need to be specified.

4. Clear Create Listener Objects in Integration Server to only extract the IDL file from the package. The wizard finishes after extracting the IDL.

   Tip:
   This is useful if you want to modify the IDL (manually) before generating clients. In this case, the connections and listeners have to be created in a separate step. See Step 4c: Create a Connection and Related Adapter Listener in the Integration Server Wrapper documentation.

5. Choose Next to store the IDL file in the selected container in the Eclipse workspace. When you go to the next page, the Back button is disabled, because the IDL file has already been created and this step cannot be reverted.

Step 4: Create or Update an Adapter Connection

As a prerequisite, the IDL file has been stored in the workspace and the Back button is now disabled.

To create a new connection

• Select a Connection type and click Next.

  Notes:

  1. An EntireX RPC Listener connection is always available.
  2. An EntireX Reliable RPC Listener connection is available if all IDL programs contain only IN parameters.
  3. An EntireX Direct RPC Listener connection is available if it is enabled by the license for the webMethods EntireX Adapter for Integration Server.

To update an existing connection

• Select a connection from the list of available listener connections and click Next.

  Notes:

  1. An EntireX RPC Listener connection is always available.
  2. An EntireX Reliable RPC Listener connection is available if all IDL programs contain only IN parameters.
  3. An EntireX Direct RPC Listener connection is available if it is enabled by the license for the webMethods EntireX Adapter for Integration Server.

Step 5: Define a Listener

To define a listener

1. Select an Integration Server package where the listener will be stored.

2. Specify the names for Folder Name (default: library name), Connection Name (default: library nameConnection) and Listener Name (default: library nameListener).

3. If necessary, edit the Broker settings for the Listener (Broker ID, Server Address, User ID, Password, and Encoding).

4. Note:
   When creating a connection, a package dependency is added such that the selected package depends on webMethods EntireX (the package WmEntireX) with the version currently used.

5. Choose Finish.

   As a result, the following objects will be created:

   • one connection of type EntireX RPC Listener, EntireX Reliable RPC Listener or EntireX Direct RPC Listener

   • one listener object

   For a connection of type EntireX Reliable RPC Listener the following objects will be created in addition for each IDL program:

   • one notification object

   • one trigger object

   • one document type object
