Java Development Tools

Hi. I'm trying to run a Java EE web application, but as soon as I launch the Weblogic I get the next message several times on the DefaultServer Log: "The system cannot find the path specified"

Here's the complete log:

*** Using port 7101 ***

Process exited.


I can run my programs perfectly on another machine with Windows XP. I've got a new machine with Vista Home Premium 64, but I have been never able to launch the server. I don't know if this has something to do with the system environment variables.

I'm using JDeveloper Studio Edition Version 11.1.1.1.0, and Weblogic Server 10.3.

Thanks in advance! :)
