The process domain is encountering the following errors while loading the process : Validation of BPEL2.0 process failed..
This error contained an exception thrown by the underlying process loader module.
Check the exception trace in the log (with logging level set to debug mode). If there is a patch installed on the server, verify that the bpelcClasspath domain property includes the patch classes.

Even though our BPEL project is compiled in jdev, during deployment it can throw the above error.

From the error message we cant make out anything.


But one of the reasons for this compilation failure could be the java embedding used inside the BPEL process. If the java code refers some external classes and if that jar files are not set in the project in the SCA/lib folder this error can happen


To resolve the error at run time the same custom jar files must be made avaiable to the BPEL Process Manager at run time .

This can be achieved by following the below process

Navigate to Oracle_Home\soa\soa\modules\oracle.soa.ext_11.1.1 directory.

Copy your custom jar files under the classes directory

Open the command prompt and navigate to \Oracle_Home\soa\soa\modules\oracle.soa.ext_11.1.1

Run the ant command


\Oracle_Home\soa\soa\modules\oracle.soa.ext_11.1.1>ant
Buildfile: C:\installed\Oracle\Middleware12C\Oracle_Home\soa\soa\modules\oracle.

Restart the Server

Importantly ensure that your .BPEL file uses the import statements for such referred classes

e.g

     <import location="oracle.xml.parser.v2.XMLElement" importType="http://schemas.oracle.com/bpel/extension/java"/>
  <import location="java.io.BufferedReader" importType="http://schemas.oracle.com/bpel/extension/java"/>
  <import location="java.io.ByteArrayOutputStream" importType="http://schemas.oracle.com/bpel/extension/java"/>
  <import location="java.io.InputStream" importType="http://schemas.oracle.com/bpel/extension/java"/>
  <import location="java.io.InputStreamReader" importType="http://schemas.oracle.com/bpel/extension/java"/>

After adding all  the  required import statements , redeploy the process
