The EntireX Listener for XML/SOAP runs in a servlet-enabled Web server with an installation of the Software AG Web Services Stack. It plugs the Web service's archives (EntireX Workbench file with extension .aar) into Web servers. Typically the Web service clients access the Listener for XML/SOAP and send/receive XML/SOAP documents using HTTP/HTTPS. This component was formerly referred to as "XML Servlet".
This document covers the following topics:
See also Web Services Stack documentation in the Software AG Infrastructure Administrator's Guide, also available under http://documentation.softwareag.com > Guides for Tools Shared by Software AG Products.
Individual settings for Web services or groups of Web services are contained in the services.xml file that is part of a Web service archive (Workbench file with extension .aar). Those settings originate from the Web Services Wrapper (default settings from generation) or from the Web Services Stack Configuration Editor (customized settings).
With an external configuration file you can override settings of the Web service's archive (EntireX Workbench file with extension .aar) without modifying the Web service archive itself. This means you can use the same Web service archive in different Web server environments.
To use an external configuration file
Define a name and a location for the external configuration file.
In the parameter section of file axis2.xml,
define a parameter "EntireX-XML-Listener" within a parameter "services".
For the attribute "location" in parameter
"services",
specify an absolute or relative path to the external configuration file.
File axis2.xml can be found in the conf
directory or folder of the Web Services Stack Web application.
<parameter name="EntireX-XML-Listener">
<parameter name="services" location="<path for file
overwriting settings of EntireX services>" />
</parameter>
Notes:
Define services in the external configuration file.
External configuration files are XML documents with a root element "serviceGroup".
A service group is defined as a sequence of one or more services.
To identify the service you are defining, specify an identifier for the attribute "name",
for instance <service name= "service100">.
To make common settings, that is, settings for all services, use an asterisk as identifier (<service name= "*">.
Note that an individual setting can override a common setting.
EntireX web service parameters that can be set are defined as subelements of "service". See the table below.
| Parameter | Description |
|---|---|
<exx-brokerID> |
The broker ID to use. |
<exx-service> |
The service name is the triplet of server class/server name/service. |
<exx-userID> |
The user ID specified here is used for calling the broker. |
<exx-password> |
The user ID specified here is used for calling the broker. |
<exx-password-encryption> |
Specifies how the password is encrypted in the configuration file. Encryption is performed automatically when the configuration file is read for the first time. |
<exx-use-security> |
Possible values: true|false. |
<exx-rpc-userID> |
The RPC user ID specified here is used for Natural Security |
<exx-rpc-password> |
The RPC Password specified here is used for Natural Security. |
<exx-natural-security> |
Enable/Disable the Natural Security (true|false). |
<exx-natural-library> |
The Natural library to use. |
<?xml version="1.0" encoding="utf-8" ?>
<serviceGroup>
<service name="*">
<exx-use-security>true</exx-use-security>
</service>
<service name="AService">
<exx-brokerID>myhost:1977</exx-brokerID>
<exx-service>RPC/ASERVICE/CALLNAT</exx-service>
<exx-userID>test</exx-userID>
</service>
</serviceGroup>
If you want to deploy Web Services Stack Web application and EntireX XML runtime to your own Apache Tomcat installation, perform the following steps:
To deploy to your own Apache Tomcat installation
Stop Apache Tomcat.
Make sure that the attribute unpackWars is set to "true" in the
server.xml of your Apache Tomcat installation.
Copy wsstack.war to the webapps directory of your Apache Tomcat installation.
Start Apache Tomcat. The content of wsstack.war will be expanded into a directory wsstack under the webapps directory of the Apache Tomcat installation.
Stop Apache Tomcat.
Copy entirex.jar from the classes directory of your EntireX installation to the WEB-INF/lib directory of the expanded Web Services Stack Web application.
Start Apache Tomcat.
Now you can deploy generated EntireX Web services (.aar) from the EntireX Workbench.
The encoding for the RPC call (broker request) depends on the setting of following parameters in the given order:
HTTP header/parameter exx-use-codepage travelling with the XML document incoming to the Listener for XML/SOAP.
Valid values:
true |
The encoding is retrieved from the incoming XML document. |
|---|---|
false |
The encoding of Java system property file.encoding.
|
<character encoding> |
the given character encoding is used. |
See also The HTTP Interface in the XML/SOAP Wrapper documentation.
Parameter Use Codepage, see Generating a Web Service, Step 4, check Set connection and security parameters in mapping file.
Parameter Use Codepage, see EntireX Settings Page under Web Services Stack Configuration Editor.
Which encodings are valid depends on the version of your JVM. For a list of valid encodings, see Supported Encodings in your Java documentation. The codepage derived after the broker's locale string mapping process must be the same as the one used to encode the data and it must be supported by the broker. See Locale String Mapping.
Enable character conversion in the broker by setting the service-specific attribute CONVERSION to "SAGTRPC".

By default, the incoming XML encoding is used for the outgoing XML document (response). This can be disabled and an encoding defined in the XML mapping file is used. See Defining the XML Encoding in the XML Mapping Editor documentation.
