Problem while deleting the user

[rashmi_setty]

We are using Jboss Portal 2.4 GA
I am trying to delete the user in jboss portal programatically using the service
in the following code

String userID="aaa"
userModule.removeUser((Serializable)userID);

there is a user with username aaa. But I am getting exception as

java.lang.IllegalArgumentException: The id is not an long : aaa
at org.jboss.portal.identity.db.UserModuleImpl.removeUser(UserModuleImpl.java:253)

How should i pass the username to removeUser function so that it delets the user.
please help
Thanks in advance

You need to specify the user id not the username

User user = userModule.findByUserName("aaa");
userModule.removeUser(user.getId());
