Jbuilder 4 and Red Hat 7.1 - license dialog hangs
The subject says it all - the license dialog appears but then becomes inoperable. You can't enter anything and the buttons do not work.
Thanks!

JBuilder 4 on Linux has IBM's SDK 1.3.0 bundled within. This SDK is totally incompatible with the glibc/libc packages in Red Hat 7.1. Sun's own 1.3.0 SDK doesn't work well, either.

Sun 1.3.1 is the only JVM known to work on Red Hat 7.1 (and other linux distrubibutions using the same or later kernel/glibcs.) Blackdown 1.3.1 FCS has just been released and may also work, but I have not heard of anything trying it yet (as of 7/13/01.)

Install Sun 1.3.1 SDK for Linux. Then edit jbuilder4/bin/jdk.config and change *all* paths to point to the corresponding bits of the new SDK.

Other symptoms of this problem include:

    JBuilder's JVM dumps core
    No keys work
    Some special keys don't work (?, <, >, etc.)

OK I will try that. I have also seen references to a fix using "export LD_ASSUME_KERNEL=2.2.5".
Does this fix this problem too? Or do we need to do both - change the JVM and export?

The LD_ASSUME_KERNEL variable is a fix for Sun's 1.3.0. It is not required for 1.3.1.

To run the installer, you need to override its internal JDK with the new one, like this:

  ./install_linux LAX_VM /usr/local/java/jdk1.3.1/bin/java

Of course, replace the path above with the real to your java executable.

Previous: (Answer) I've just installed JB4 Foundation on Solaris 2.6. I've applied all of the Solaris patches required by JDK 1.3. When I try to launch jbuilder, I get the following error: /opt/jbuilder4/bin/jbuilder[47]: ./*.config: not found. What is wrong?
Next: (Answer) I'm trying to install JBuilder 5 on Solaris 2.7 but I'm getting the following error message: /tmp/install.dir.24417/Linux/resource/jre/bin/java: test: argument expected
