Start Web Logic 5.1 in a separate JVM

Question

Hi All.
Is there a way to start Web Logic 5.1 in a separate JVM from within a java class.
I am writing a service pack for a Web Logic application. During the service pack
uninstall, I have to stop web logic, delete the new files, restore old files and
restart web logic.
For restarting, I am using a JNI call to invoke the web logic startup class. This
runs in its own java.exe process. But even after the uninstaller's java.exe quits,
the java.exe that is running web logic holds a lock on to the folder from where
the uininstaller was launched.
Does anyone know why this is happening?
Is there a solution to this issue?
Your help would be much appreciated.
Thanks Jai

Answer 1

In your function that you call with JNI, before you launch the new WebLogic
process, you should set the current working directory to the WebLogic
directory and everything will work fine.
I have no explanation for why the directory remains locked.
