Resolution:
OC4J's javaw.exe is looking for the following dlls under"C:/Documents and Settings/${user}/Windows/System32" directory instead of"C:/Windows/System32" directory.


Copy the following from C:/Windows/System32 to the above user specific directory to fix this issue.

- mswsock.dll
- winrnr.dll
- wshtcpip.dll

OC4J Fails to Deploy Applications on Windows 2005 Server

Application deployment console(em) spins its wheel but fails to complete deployment.

Resolution:
This happens because of missing temp directory.
Check ias-instance/environment/variable@value in opmn/conf/opmn.xml for id="TMP".
If this directory does not exist on the server, then the console fails to complete,but does not error out while deploying an application.

A more descriptive message can be seen while deploying from command line.
