Java libgcj-java-placeholder.sh Issues

Question

Hello,
I installed j2sdk1.4.2_05 and j2re1.4.2_05 unser /usr/java on my RHEL server.
When typing "which java" and "java -version", under the "oracle" user I do not get the version installed.
Instead, I get a message "...libgcj-java-placeholder.sh..." relating.
When trying to run a shell, i get an error "Java Class not found".
1) How can I resolve this issue ?

Answer 1

This is the content of my PATH variable in my .bash_profile file:
PATH=/usr/bin:$ORACLE_HOME/bin:$PATH:$HOME/bin:/usr/bin/java:/usr/sbin:/usr/java/jdk1.4.2_05/bin; export PATH
PATH=$PATH:$ORACLE_HOME5/jdk/jre/lib/i386:$ORACLE_HOME5/jdk/jre/lib/i386/server; export PATH
----Looks like your PATH variable is trying to be confusing. Why we are seeing $ORACLE_HOME and $ORACLE_HOME5? "/usr/bin/java", not a directory I assume, has no effect here.
To resolve your issue, please replace the above two lines with one single line:
PATH=/usr/java/jdk1.4.2_05/bin:$ORACLE_HOME/bin:/usr/bin:$PATH:$HOME/bin:/usr/sbin; export PATH
The order of the paths that appear in $PATH are important. Here "/usr/java/jdk1.4.2_05/bin" is put at the very front. I also assume that your are using $ORACLE_HOME instead of $ORACLE_HOME5; otherwise, you can switch them.
As orafad mentioned, I strongly recommend that you replace the "/usr/java/jdk1.4.2_05/bin" with $ORACLE_HOME/jdk/bin, if the later is a valid location as it should.
At any time, you can always see what java executables you have in your $PATH by running the following bash commands in your bash shell:
  for dir in `echo $PATH | tr ":" " "` ; do if [ -x $dir/java ]; then ls $dir/java; fi; done
The very first line of output is the java you are using. This command can be helpful when the $PATH gets more complicated.
