Help needed in implementing validation event handler in OIM 11g

Question

Hello experts,
I am trying to set username policy by implementing a validation event handler in OIM 11.1.1.5.
Following are the steps followed
1. Import metadata
Created a file called Eventhandler.xml as below and imported using weblogicImportmetadata.sh
<?xml version='1.0' encoding='UTF-8'?>
<eventhandlers xmlns="http://www.oracle.com/schema/oim/platform/kernel" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://www.oracle.com/schema/oim/platform/kernel orchestration-handlers.xsd">
<validation-handler class="test.iam.eventhandlers.CustomValidationEventHandler" entity-type="User" operation="CREATE" name="CustomValidationEventHandler" order="1000" sync="TRUE"/>
</eventhandlers>
2. Register plugin
plugin.xml
<?xml version="1.0" encoding="UTF-8"?>
<oimplugins xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance">
<plugins pluginpoint="oracle.iam.platform.kernel.spi.ValidationHandler">
<plugin pluginclass="test.iam.eventhandlers.CustomValidationEventHandler" version="1.0" name="CustomValidationEventHandler" />
</plugins>
</oimplugins>
Just givng sys out in the below code to check whther it is getting triggerred during user create.
package test.iam.eventhandlers;
import java.util.HashMap;
import oracle.iam.platform.Platform;
import oracle.iam.platform.context.ContextAware;
import oracle.iam.platform.kernel.ValidationException;
import oracle.iam.platform.kernel.ValidationFailedException;
import oracle.iam.platform.kernel.spi.ValidationHandler;
import oracle.iam.platform.kernel.vo.BulkEventResult;
import oracle.iam.platform.kernel.vo.BulkOrchestration;
import oracle.iam.platform.kernel.vo.Orchestration;
public class CustomValidationEventHandler implements ValidationHandler {
     @Override
     public void initialize(HashMap<String, String> arg0) {
     // TODO initialization
          System.out.println("init validate event handler");
     @Override
     public void validate(long processId, long eventId, Orchestration orchestration)
     throws ValidationException, ValidationFailedException {
          System.out.println("Beginning of validation");
          System.out.println("End of validation");
     @Override
     public void validate(long processId, long eventId, BulkOrchestration arg2)
     throws ValidationException, ValidationFailedException {
     // TODO - N/A
          System.out.println("Bulk Orchestration not yet implemented");     
Now when i create a user it is not allowing and i am getting system error in the front end and in the logs i could see something below
<May 28, 2012 3:03:29 PM CEST> <Error> <oracle.iam.identity.usermgmt.impl> <IAM-3050029> <The user cannot be created due to validation errors.
oracle.iam.platform.kernel.ValidationFailedException: Event handler CustomValidationEventHandler implemented using class/plug-test.iam.eventhandlers.CustomValidationEventHandler could not be loaded.

I have implemented preprocess and postprocess event handler before with similar kind of plugin registration, metadata import and everything worked fine. Not sure what is the problem here with validation event handler.
Thanks

Answer 1

Instead of registering the plug-in can u try placing it in the plugins folder under Oracle_IDM1/server folder.
at times restart is required. esp when the server is running in production mode.
