Installation of application MAXIMO failed.

Problem:
I changed some class files to alter the functionality of Maximo. I did a rebuild of the ear file. I 'Uninstalled' the MAXIMO application from websphere.

I Installed MAXIMO again, but the serer did not respond. So i should have waited, but I started a new install of MAXIMO. Now the system is giving met the following error:

"A composition unit with name MAXIMO already exists. Select a different application name.

ADMA5011I: The cleanup of the temp directory for application MAXIMO is complete

ADMA5014E: The installation of application MAXIMO failed.

Used environment: 
Windows 2008 r2 server, 64 bit
Websphere 7.0.0.15
Maximo 7.5.0.5


The Solution:
(Note that all paths mentioned below could be different on your system depending the path where you installed Websphere)

• Stop the MXServer

• Stop the Maximo services;
• IBMWAS70Service - ctgCellManager01
• IBMWAS70Service - nodeagent

• Deleted the "MAXIMO" Directory deleted from:
• D:\IBM\WebSphere\AppServer\profiles\ctgDmgr01\config\cells\ctgCell01\blas
• D:\IBM\WebSphere\AppServer\profiles\ctgDmgr01\config\cells\ctgCell01\cus

• Delete the "MAXIMO.ear" from:
• D:\IBM\WebSphere\AppServer\profiles\ctgAppSrv01\config\cells\ctgCell01\applications
• D:\IBM\WebSphere\AppServer\profiles\ctgDmgr01\config\cells\ctgCell01\applications

• Delete all files in the following directories:
• D:\IBM\WebSphere\AppServer\profiles\ctgAppSrv01\temp
• D:\IBM\WebSphere\AppServer\profiles\ctgAppSrv01\wstemp
• D:\IBM\WebSphere\AppServer\profiles\ctgAppSrv01\config\temp

• D:\IBM\WebSphere\AppServer\profiles\ctgDmgr01\temp
• D:\IBM\WebSphere\AppServer\profiles\ctgDmgr01\wstemp
• D:\IBM\WebSphere\AppServer\profiles\ctgDmgr01\config\temp

• Start the Maximo services;
• IBMWAS70Service - ctgCellManager01
• IBMWAS70Service - nodeagent

• Install MAXIMO, all should go well now.
