Using the XML/SOAP Wrapper

This document covers the following topics:

See also Migration Considerations for XML/SOAP Components.


Mapping IDL Parameters to XML Structures

Use the XML Mapping Editor to map IDL parameters to XML structures.

The mapping editor offers several mapping types:

In addition, the mapping editor shows one of general information (Overview page), the request message (XML Request), response message within fault information (XML Response page), mapping parameters (Mapping Parameters page) or sample editor (XML Samples page) at one time.

Setting Wrapper Properties

Before you start the generation of the XMM file, select the IDL file and open the context menu to set the properties for this IDL file. The settings for an IDL file are inherited from the preferences (they provide the defaults):

Start of instruction setTo set the general options, path settings and XML options

  1. Select Preferences... in the Windows menu of Eclipse.

  2. Select Software AG > EntireX.

  3. Select the tab XML.

  4. Fill in the screen as follows:

    Screen Item Description
    XML default encoding This encoding is used for the XML/SOAP document sent, if the box "Use incoming XML encoding" is not checked (for XML-based clients) or if the XML/SOAP RPC Server is used.
    Use incoming XML encoding Check this box to enable the XML/SOAP Wrapper to use same encoding for the incoming document as for the outgoing document.
  5. Confirm the settings with OK.

After setting the general properties, set the properties specific to the IDL file. The settings for the XML/SOAP Wrapper classes are on the two tab pages: General and XML.

Start of instruction setTo set the IDL properties

  1. In the file tree browser, select the IDL file to be processed.

  2. To display the Properties window, use either the context menu or the File menu and choose Properties.

    The subsequent screen will show the defaults you entered with Tools > Options..

  3. Use this page to specify the Broker ID, the server address (Server class, Server name, and Service) and other properties. If you do not enter Broker ID, server name, etc., the defaults (as entered in the Tools / Options menu) will be used.

  4. Select the XML tab.

  5. Complete the screen as follows:

    Screen Item Description
    XML default encoding This encoding is used for the XML/SOAP document sent, if the box "Use incoming XML encoding" is not checked (for XML-based Clients) or if the XML/SOAP RPC Server is used.
    Use incoming XML encoding Check this box to enable the XML/SOAP Wrapper to use the same encoding for the incoming document as that used for the document sent.
  6. Confirm the settings with OK.

Generating an XMM File

To generate the XMM file, use the EntireX Workbench.

The IDL file, the XML file and the properties are used to generate an XMM file.

Start of instruction setTo generate the XMM file

  1. Specify an IDL-XML mapping.

  2. Save the mapping.

If you are using the default settings of the EntireX Workbench, an XMM file is saved. The name of the XMM file is <idl file name>.xmm

Warning:
If you modify the IDL file, the IDL-XML mapping file or the properties, you must re-generate the XMM file.

Default Values Used by the XML/SOAP Runtime

The XML/SOAP Runtime uses standard default values for all parameters (for EntireX RPC) and elements/attributes (for XML documents) if no value can be retrieved and no user default value is defined. The table below shows the standard default values for XML and RPC.

Value Description
A(n) XML: Empty string with length 0
RPC: String with n blanks
AV Empty string with length 0
B(n) String with n zeros
BV Empty field with length 0
K(n) XML: Empty string with length 0
RPC: String with n blanks
KV Empty string with length 0
L false
I1 0
I2 0
I4 0
F4 0.0
F8 0.0
N 0.0
P 0.0
D new Date()
T new Date()
U(n) XML: Empty Unicode string with length 0
RPC: Unicode String with n blanks
UV XML: Empty Unicode string with length 0
