Java Development Tools

I had some prototype apps working on the JDEV development box. That included running the apps on the browsers on that machine and the blackberry simulator. I was also able to run the apps on my blackberry phone.

I created a new application and had some weblogic error. Someone had an old post and suggested going to Application/Properties/Deployment/Weblogic and clicking on sync JDBC descriptors. I did that but subsequent to that I could not run the apps on my blackberry phone anymore ( simulator worked ok and browser access on the dev box worked ok ).

Does anyone have any ideas how to restore back to original working condition and any explanation as to what is going on?

thanks
John
