Resetting the OC4J password in OBIEE

We recently had to uninstall the OBIEE installation on our development server but unfortunately noone remembered the password in the team. After some reasearch we were able to figure out a way to reset the OC4J Admin password.
Open up the file ORACLE_HOME\oc4j_bi\j2ee\home\config\system-jazn-data.xml in a text editor.
Find the line that defines the credentials property for the admin user
Enter the new password prefixed by an exclamation mark between the credentials tag e.g. – ” !newpassword “
Start the services and you should be able to uninstall OBIEE with the new password.
<user>
<name>oc4jadmin</name>
<display-name>OC4J Administrator</display-name>
<guid>0E645260306811DCBFEA1DBAFA3DF35A</guid>
<description>OC4J Administrator</description>
<credentials>{903}MnAD+UUULZVKTheGctZt+WWD8IYOmYh/</credentials>
</user>
Replace the existing encrypted password with the new password.
Be sure to prefix the password with an exclamation point (!). For example:
<credentials>!newpassword</credentials>
