All you probably need is "Java 2 Standard Edition (J2SE) Runtime".

Do this and you should be fine (the link has the steps, screenshots, and direct shortcuts to the J2EE runtime download itself):

'Hope that helps .. PSM

Please post back if you have any questions, or encounter any problems.

For most apps, the JRE I described above is all you need.

If your app needs something extra ... then you need to tell us exactly what your app is, and what it says it needs. Feel free to cut/paste from the app's README.

OK then , thank for this support ,

my application is called H2O or Hermes 2.0 ,
its a EDI messaging system . basicly a Java web application . that runs under Tomcat5 .

Iam trying to download this under Fedora 8 system.

I got tomcat5 running with yum install and the manager site is working fine. the thing is with H2O it self i cant get it to work . it give me some weird Errors ???

i would post them soon . just give me a chance to do a fresh install to this system .

thanx

OK - but please forget most of what I just told you ;-)

What I said is true for a Java-based application, or a Java plugin. But not a JSP/Servlet-based web app.

If you're using Tomcat, you probably need a full-fledged JDK (not just the JRE Java runtime). And you also need to configure your .war files (libraries, web descriptors, etc) correctly. In theory, a .war should be a simple file-copy. In practice, you'll probably have to do some manual configuration.

In any case: please keep us posted as to your progress.

Hi -

I'm sorry, but this is a lot bigger and more complicated than I suspected from your initial post.

For whatever it's worth, your first problem is here:
Quote:
java.lang.NoClassDefFoundError: hk.hku.cecid.piazza.commons.Sys
java.lang.Class.initializeClass(libgcj.so.8rh)
hk.hku.cecid.piazza.commons.servlet.http.HttpDispatcher.init(HttpDispatcher.java:63)
org.apache.catalina.authenticator.AuthenticatorBase.invoke(catalina-5.5.23.jar.so)
...
You loaded Sun Java (good) ... but Tomcat is picking up GNU Java (completely incompatible) ... and it can't find one (or more!) of H2O's classes (hk.hku.cecid.piazza.commons.Sys).

There appear to be a lot of "moving parts" in this project(Tomcat, Java, PostgreSQL, JAAS authentication, etc etc): it's not necessarily going to be trivial to set up.

I'd strongly suggest working with the company that released this product, CECID:

http://www.cecid.hku.hk/open-source.php

Sorry I can't be of more help .. PSM
