HP Java support

pc123_1 — Fri, 21 Jun 2002 09:20:54 GMT

Hi.
I have installed the latest version of Tomcat (4.0). It doesn't start due to some java classes missing.
My question is:
1. What version of Java can be installed on HP-UX? The current Java 2 1.4 doesn't have an install package for HP-UX? Is there an HP site with HP Java packages?
2. Will tomcat run on HP-UX?

Hopefully someone here had experience with Java on HP-UX. I will appreciate all comments.

There are two sets of Java packages - for PA-RISC and Itanium. Which one to choose without having all hardware docs at the moment?

That would depend on your server/OS. Do you have an Itanium server or a PA-RISC base server?

Before I install the latest version...

Here's answer to a question i found in Java FAQ:

************************
: I downloaded Java and got the error: "Unable to initialize threads -- cannot find class java/lang/thread". What should I do?

A: For most users, the java wrapper script will take care of setting the JAVA_HOME environment variable and will add the appropriate entries to the CLASSPATH so that the JVM finds the standard API classes.

The PATH environment variable needs to include a path to the java wrapper script. People writing applications with non-Java mains may need to worry about the setting of CLASSPATH and SHLIB_PATH. They can set CLASSPATH in the JDK1_1InitArgs structure passed to JNI_CreateJavaVM(). They need to ensure that SHLIB_PATH is set to include the directories where the JVM shared libraries are found (typically ${JAVA_HOME}/lib/PA_RISC/green_threads or ${JAVA_HOME}/lib/PA_RISC/native_threads). SHLIB_PATH must be set prior to launching the application. Using setenv() to set SHLIB_PATH within the application will not have an effect on how the dld searches for shared libraries.
***************************

My question is: How do I set the java wrapper class in CLASSPATH? The Unix server I got came with preinstalled Java, however no JAVA_HOME and CLASSPATH env. variables were set. And I am having trouble finding install info on hp site.

Hi,
Appended the nessecary PATH in
/etc/PATH file
Append the nessecary SHLIB_PATH in
/etc/SHLIB_PATH
And for CLASSPATH do this
#export CLASSPATH=/opt/java/class (or whatever)
