The examples in this chapter focus primarily on how to embed Java code snippets with the bpelx:exec extension. For BPEL projects that support version 2.0 of the BPEL specification, the syntax is slightly different. The bpelx:exec extension and Java code are wrapped in an <extensionActivity> element. The following example provides details.

<extensionActivity>
  <bpelx:exec language="java">
  <![CDATA[
    java code
  ]]>
  </bpelx:exec>
</extensionActivity>

When you drag a Java Embedding activity into a BPEL process in Oracle BPEL Designer, the <extensionActivity> element and bpelx:exec tag are automatically added.

The following example shows the import syntax for BPEL 2.0:

<import location="class/package name"
 importType="http://schemas.oracle.com/bpel/extension/java"/>

<bpelx:exec import="class/package name"/>

The following example shows a BPEL file with two Java embedding activities for a project that supports BPEL version 2.0.

<process name="Test" targetNamespace="http://samples.otn.com/bpel2.0/ch10.9"
     . . .
     . . .
 <import location="oracle.xml.parser.v2.XMLElement"
     importType="http://schemas.oracle.com/bpel/extension/java"/>
. . . 
 <sequence>   
 . . .
<extensionActivity>
     <bpelx:exec language="java">
         XMLElement elem = (XMLElement) getVariableData("output", "payload");
         elem.setTextContent("set by java exec");
     </bpelx:exec>
   </extensionActivity>

   <extensionActivity>
     <bpelx:exec language="java">
         <![CDATA[XMLElement elem = (XMLElement) getVariableData("output",
          "payload");
         String t = elem.getTextContent();
         elem.setTextContent(t + ", set by java exec 2");]]>
     </bpelx:exec>
   </extensionActivity>
  . . .
 </sequence>
</process>
