Java on Linux

Javier Herlein — Tue, 28 Oct 2003 06:52:50 GMT

I am trying to install J2SE (donwloaded from Sun) on a RX5670 server with Red Hat Linux 7.2.
I first tried with J2SDK 1.4.2 but the installation process doesn't seems to progress, it just keeps displaying a white window and makes no progress.
Then I tried with JDK 1.2.2, which seems to install succesfully (it's just a tar file). Then where I run the java command I get the following error message: "Error: can't find libjava.so."

I'm not sure if these versions are compatible with the Linux version I'm running (Red Hat Linux Advanced Server 2.1 for the Itanium Processor).

Any idea?

The right version for you is 1.3.1, but what are you trying to use Java for ? Programming or runnig a program that requires it ?

I need to install Java because the application requires it (Oracle 9i App Server).

AFAIK Oracle has very specific requirements concerning the Java version they want to have on the system.

Check

for a detailed discussion of the installation.

The problem is that the Java versions I installed seem to be incompatible with the machine.
After the installation (which seems to finish correctly), when I type java -version I get the following error message:

./../jre/bin/realpath: /J2SE/jdk1.3.1_09/bin/../jre/bin/ia64/realpath: No such file or directory
./../jre/bin/realpath: exec: /J2SE/jdk1.3.1_09/bin/../jre/bin/ia64/realpath: cannot execute: No such file or directory
./java: /bin/realpath: No such file or directory
./java: /bin/realpath: No such file or directory
grep: /lib/jvm.cfg: No such file or directory
grep: /lib/jvm.cfg: No such file or directory
java was not found in /bin/i386/native_threads/java

The problem is that the JVM I installed does not include the ia64 subdirectory.

Looks exactly like you say. You need to download the i386 version, not the ia64 unless you have a 64 bit machine.
