Which version of java and javac were installed? What rpms were they part of? And do they rpms still believe they are installed? java and javac are part of the rpm j2sdk-1.4.2_03-fcs Yes they are installed. By hand I have fixed up the soft links from /usr/bin/java[c] to /etc/alternatives/java[c] to /usr/java/j2sdk1.4.2_03/bin/java[c] I had to spend at least an hour researching how to do this but, a worse problem is that necessary functions were broken for some time before this was discovered. I believe that installing an unrelated rpm should not cause this kind of grief. If it is going to make such a change, the least it could do is give a detailed message describing the links that have to be set up rather than the cryptic message that is now produced. Better yet, when an rpm breaks existing links in order to implement alternatives, the installer should include logic to determine which alternative is currently being used. Instead an alternative was set up that few on earth choose to use. This is all too reminiscent of the way things are done in MS land. It should be sufficient to have /usr/java/j2sdk1.4.2_03/bin appear in PATH before /usr/bin (rather than altering the symlinks by hand). This change was designed to work with supported RHEL3 JVM packages. It causes problems however, if a non-RHEL3 JVM's bin directory appears after /usr/bin in the PATH. The new libgcj rpm (for the reasons described in the placeholder script) installs java and javac alternatives symlinks in /usr/bin, so it overrides any java commands that appear after /usr/bin in PATH. I'll append a message to this effect to the output of the placeholder script in the next release of libgcj. I'm appending this message to the placeholder script's output: This script was designed to be overridden by the supported RHEL3 JRE packages, java-1.4.2-bea and java-1.4.2-ibm. It is installed as an alternative symlink as /usr/bin/java. It will override a third-party (non-RHEL3) JRE's java command if the JRE's bin directory is listed after /usr/bin in PATH. In that case, it is recommended that the third-party JRE's bin directory be listed first in PATH instead. That last comment applied to libgcj-java-placeholder.sh. To libgcj-javac-placeholder.sh I'll add: This script was designed to be overridden by the supported RHEL3 SDK packages, java-1.4.2-bea-devel and java-1.4.2-ibm-devel. It is installed as an alternative symlink as /usr/bin/javac. It will override a third-party (non-RHEL3) SDK's javac command if the SDK's bin directory is listed after /usr/bin in PATH. In that case, it is recommended that the third-party SDK's bin directory be listed first in PATH instead. New text in libgcj-3.2.3-47.

The damage was done by up2date. I have not been able to find any work-around described. Version-Release number of selected component (if applicable): How reproducible: Always Steps to Reproduce: 1.javac x.java 2. 3. Actual Results: A place holder scrit runs instead of the compiler or the run-time. The place holder outputs a cryptic messages to stdout. Expected Results: javac should run java should run Additional info:
