WSRP Producer portal

Learn how to configure and use a handler on a WSRP Producer portal.

We can configure handlers for the WSRP Producer in the wps.ear portal application.

Starting with CF05, we can register handlers that implement the SOAPHandler interface as an extension of a WSRP extension point. In this case, you do not need to modify the portal application. For details, read the information in a later section.

Use a handler on a WSRP Producer portal

1. Create a handler implementation according to the JAX-WS specification. For details about the handler framework, read the JAX-WS specification. For information about using handlers with JAX-WS web services, read the appropriate information in the WebSphere Application Server documentation.
2. Provide the handler implementation in the class path of the wps.ear portal application, for example in the portal shared application directory.
3. Export the wps.ear portal application. The exported wps.ear file contains a wps.war. The WEB-INF/classes directory in the wps.war file contains two files wp.wsrp.producer-v1-handlerchain.xml and wp.wsrp.producer-v2-handlerchain.xml.

4. Modify either one of the files wp.wsrp.producer-v1-handlerchain.xml or wp.wsrp.producer-v2-handlerchain.xml. Update the default handler-chains element by adding one or more handler elements.
5. Update the wps.ear portal application.

6. Restart your WSRP Producer portal.

We can now use the handler in your Producer portal

Example

The following samples show excerpts from the file wp.wsrp.producer-v2-handlerchain.xml. The samples contain a handler definition for the WSRP Producer.Before CF 05:

<?xml version="1.0" encoding="UTF-8"?>
<ns:handler-chains xmlns:ns="http://java.sun.com/xml/ns/javaee">
    <ns:handler-chain name="wp.wsrp.producer-v2-handlerchain">
        <ns:handler>
            <ns:handler-class>sample.handler.ProducerHandler</ns:handler-class>
        </ns:handler>
    </ns:handler-chain>
</ns:handler-chains>

With CF 05 and later fix packs, we must not modify the default handler definition for the handler class com.ibm.wps.wsrp.producer.handler.ProducerHandlerChain. We can add more handlers as shown in the following example:

<?xml version="1.0" encoding="UTF-8"?>
<ns:handler-chains xmlns:ns="http://java.sun.com/xml/ns/javaee">
    <ns:handler-chain name="wp.wsrp.producer-v2-handlerchain">
        <ns:handler>
            <ns:handler-class>com.ibm.wps.wsrp.producer.handler.ProducerHandlerChain</ns:handler-class>
        </ns:handler> 
        <ns:handler>
            <ns:handler-class>sample.handler.ProducerHandler</ns:handler-class>
        </ns:handler>
    </ns:handler-chain>
</ns:handler-chains>

Register a SOAPHandler as a WSRP extension

To register a handler that implements the SOAPHandler interface, we can use a WSRP extension point. In this case, you do not need to modify the portal application. To do so, provide a JAR file that contains the handler implementation and a plugin.xml file that defines an extension of extension point com.ibm.portal.wsrp.producer.SOAPHandler. We can also define multiple handlers inside one plugin.xml file as shown in the following example. The class attribute must specify the handler implementation class.

<?xml version="1.0" encoding="UTF-8"?>
<plugin
    
    name="Sample WSRP Handlers"
    version="1.0.0">
	
    <extension point="com.ibm.portal.wsrp.producer.SOAPHandler" >
        <impl class="com.ibm.wps.wsrp.test.handler.ProducerHandler1" weight="100"/>
    </extension>
    <extension point=" com.ibm.portal.wsrp.producer.SOAPHandler" >
        <impl class="com.ibm.wps.wsrp.test.handler.ProducerHandler2" weight="110"/>
    </extension>
</plugin>
