Java Embedding in Oracle BPEL process
In this section, we walk through about how to call a Java method in BPEL process 2.0.
I have created a Java class in my SOA project as shown below. The class name is FirstJava.java; it has a single method getString which returns a string
Open the BPEL process >> Search Java in the component >> Drag the Java Embedding and drop it to the BPEL process
Double click on the Java Embedding
Input the below code as shown below
FirstJava obj = new FirstJava(); \\ Creating object
String name = obj.getString("catgovind"); \\ Return 'Hello catgovind'
setVariableData("myname", name); \\ set the variable to BPEL process variable 'myname'
Click the Source tab of the BPEL process >> Import the java class below the process element as shown below
<import location=”com.catgovind.FirstJava” importType=”http://schemas.oracle.com/bpel/extension/java”/>
Follow the steps If you want to add a jar file instead of creating Java classes inside the SOA project
1. Export your existing Java project into a Jar file
2. place the jar file inside <SOA_PROJECT_HOME>\SOA\SCA-INF\lib (Example: C:\JDeveloper\mywork\SOAApplication\Project\SOA\SCA-INF\lib)
3. Right-click the SOA project >> Click Properties >> Select Libraries and Classpath >> Click button Add Jar/Directory >> Add the jar file from the SCA_INF\lib directory
4. Follow the remaining screenshots as presented above expect the first image
