The Spring component makes it possible to embed Java code as a Service Component Architecture (SCA) first-class citizen through the Spring component implementation type. Thereby the coarse-grained components of Oracle SOA Suite (such as BPEL, Mediator) can be extended by much-finer-grained Spring beans wrapped inside the Spring component.
This tutorial explains in short how to embed a spring component with SOA BPEL.
Follow the steps below sequentially
STEP 1 : Go to Jdeveloper Home Page -> Select File -> New-> Generic Project --> Click OK
STEP 2 : Provide Project Name -> Select Soa Services as shown below :
STEP 3 : Click Next -> Select Composite With Bpel Process --> Click Finish
STEP 4 : Select Type of Bpel you want to choose finally Click OK.Your Bpel will come as shown below.
Step 5 : On right hand side Go To Services Component Palette-> Select Spring Component --> Place it on components palette.Then Below screen will apppear .Put name and click OK.
STEP 6 : Now we need to create a java class.Go To File -> New -> All Technolgies Tab-->Select Option Java --> On right side Select Java class and click OK.The below screen appears provide details as you wish and Click OK.
STEP 7 : On this an option will come select first one and click OK.
STEP 8 : Now a java class is created under a package.We need to write some code to make it work.
STEP 9 : Write the below snipet of code in java class section :
package com.test1;
public class mytest {
public mytest() {
super();
}
public String read(String input) {
return "hello" + input;
}
}
STEP 10 : Next we need to create a java interface.Click File-> New->All Technologies->Java->Select Java Interface-> Click OK.
STEP 11 : The below snippet will come.Put details as shown below and click OK.
STEP 12 : Just Write the below lines of code and click OK.
package com.test1;
public interface Interfacetest {
public String read(String input);
}
STEP 13 : Go back to composite.xml. Double click on spring component.Write below lines of code .This will actuaally map bpel with java class via spring.
<!--Spring Bean definitions go here-->
<bean class="com.test1.Interfacetest" id="impl" />
<sca:service name="test" target="impl" type="com.test1.Interfacetest"/>
</beans>
STEP 14 : After that you will be asked to generate wsdl if you a question mark tab will come : Click OK.
STEP 15.Again you will be prompted to ask another question click OK.
STEP 16 : Your spring is ready.It will look like this :
STEP 17 : Now double click on Bpel component.Drag an invoke activity and and an assign activity ,map invoke with spring component and you complete bpel looks like this :
STEP 18 : Double click on assign activity,map source input with spring input as shown below :
STEP 18. Our code is ready.Compile test ,deploy your services on weblogic server.

Happy Coding............
