JBuilder 9 problem

Hi, I'm new to this forum, mainly from desperation. I hope this is the correct place to post this question. I have just installed JBuilder 9 on my PC (windows XP prof). The installation seemed to go smoothly, but I cannot build any applications. Even the demo app does not build! I get the following fatal error:
"WelcomeApp.java": Fatal Error: Unable to locate package java.lang in classpath or bootclasspath
What can I do to solve this problem? I've spent the last two days searching the web, and looking through the borland website but have found nothing useful
Do I need to change a configuration file or something?
Thanks in advance

First, might I recommend JDeveloper 9? Slick and quick, full of good info. However, I used to use JBuilder for awhile. I know that these IDE's can use different versions of Java. Usually in the "Project Preferences" or "Tools | Options" or something like that, you can find a place to specify which Java implementation you want to use. The IDE comes with one (usually 1.3 or whatever, depending on how recent you got it). But you can install the JDK1.4 and specify somewhere that that is what you wish to use. Also, I'd check that your paths are working correctly by trying to compile from command line. Hope that helps!

Hi David

I am using JbuilderX and faced the same problem when I opened an old project to upgrade.

I noticed that it was using jdk1.3 and when changed that it worked fine.


It is under Project -> Project Properties...

Hope this is useful for others and thanks to you pointing the right spot
