How to reset the OIM password without using the Identity Manager UI

Typically the ODSM (Oracle Directory Services Manager) allows the user to change the passwords using the url http://hostname:7005/odsm . There are situations where one needs to change the password via a Java Web Service. This Post uses the OID (Oracle Internet Directory) Java API to reset password information.
