Creating an Event Handler in OIM

1.  Copy the following code into a java file and then export it to the  OIM-HOME\xellerate\evenhandler folder.
2.  Now open the Development Tools -> Business Rule Definition -> Event Handler Manager in the design console.
3. Create a new Event Handler and specify:
   Event Handler Name: tcGenerateRandomPassword
4. In the package name give the package in which the class is present.
5. Select the pre-insert checkbox and then save the event handler.
6. Now Goto Development Tools -> Business Rule Definition -> Data Object Manager
7. Search for "Users" and add the event handler to the Pre-Insert list.
8. Save it.

Now once you create a user in xellerate it will generate a random password for the user. Try logging in with the password generated and you should be able to login successfully.
