Validation eventhanlder in OIM 11G R1 11.1.1.5.4

Question

Hi Experts,
I have a requirement to validate the data entered in the CREATE USER form of OIM Admin console.
example: I have a UDF called mobile number, when a HELPDESK team enters data in the UDF, OIM should immediately verify it's a number or not and throw error message saying the value entered is not unique.
Can I achieve this VALIDATION event handler? or is there any other way to achieve this?
OIM version: OIM R1 11.1.1.5.4
Thanks in Advance!!!

Thanks for quick reply,
There are only two buttons ( Save, Cancel) on create user form. Does the submit button mean SAVE button ??
Can you provide any sample code for that??
I tried using below code
package project4_eventhandlers_localr1;
import java.io.Serializable;
import java.util.HashMap;
import oracle.iam.platform.kernel.ValidationFailedException;
import oracle.iam.platform.kernel.spi.ValidationHandler;
import oracle.iam.platform.kernel.vo.BulkOrchestration;
import oracle.iam.platform.kernel.vo.Orchestration;
public class validationEventhandler implements ValidationHandler {
    public void initialize(HashMap<String, String> hashMap) {
    public void validate(long l, long l1, Orchestration orchestration) {
        HashMap<String, Serializable> ParametersArray =
            orchestration.getParameters();
        String TestAttribute = (String)ParametersArray.get("USR_UDF_TESTATTRIBUTE");
            System.out.println("TestAttribute value" + TestAttribute);
            if (TestAttribute.contains("TEST")) {
                  throw new ValidationFailedException();
    public void validate(long l, long l1,
                         BulkOrchestration bulkOrchestration) {
EventHandlers.xml is as shown below
<?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

    <validation-handler

    entity-type="User"
    operation="MODIFY"
    name="validationEventhandler"
    order="3012346"/>
</eventhandlers>
Plug.xml is
<?xml version="1.0" encoding="UTF-8"?>
<oimplugins xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance">
  <plugins pluginpoint="oracle.iam.platform.kernel.spi.EventHandler">
    <plugin pluginclass= "project4_eventhandlers_localr1.validationEventhandler"
            version="1.0" name="validationEventhandler">
    </plugin>
  </plugins>
</oimplugins>
But when I create a user SAVE button I am receiving following error in DIAGNOSTIC LOG irrespective of data I give....
and on the Create user form it shows a pop up message " A system error occurred "
