problem with symbolic link to java

[yuanml]

created a symbolic link to java (JDK/bin/java or JDK/jre/bin/PA_RISC2.0/native_threads/java).

When I invoke the symbolic link, got the coredump error. But if I call the java directly, it succeeded. See the example below.
Anybody has the same problem before? Please advise.

$ls -l mjava
lrwxr-xr-x 1 clarify dba 54 Mar 1 12:57 mjava -> /opt/bea/jdk131/jre/bin/PA_RISC2.0/native_threads/java

I would recommend installing patches and the latest java 1.3.x patches from http://www.hp.com/go/java

Also, why are you using a symbollic link? You can set an environment variable to point various scripts and applications to the right version of JAVA.

JAVA_BIN=/opt/java

That kind of thing.

>> file corrupt
if file corrupt, why the java itself works?

>>Why do I use symbolic link?
To find and kill the Java process easily.
We have a few java process running at the same time. When you use ps to list process, all java process are named "/opt/..../jre/bin/PA_RISC2.0/native_threads/java -classpath...", you don't know which process is which. Symbolic Link is a good solution to this problem

file core will tell you what signal/program caused the core file.
