Error starting the demo

Hi all,

I am trying to run the simple demo (build run.demo) on Windows using JBoss Cache 1.02. I get the following output:

Of course, nothig starts. This worked just fine with 1.01 (I just tried on this same machine).

Any help is appreciated. Am I doing something wrong? From the tutorial, it does not seem so.

Thanks,
Cristi

Cristi,

Hmmn, I don't know what happened but "build.bat run.demo" works fine on my XP box with 1.02 release.

I am running JDK1.4.2_06.

Hi Ben,

I am using JDK 1.4.2_04 on Win2K Pro.

Can you tell me which is the document loaded in:

org.jboss.cache.PropertyConfigurator.loadDocument(PropertyConfigurator.java:92) (or where do I find the sources to look myself ;-))?

Maybe there is a mistake in that XML file.

Thanks,
Cristi

You can download the cvs source from sourceforge under jboss-head. You should use -r JBossCache1_0x to check out the 1.02 branch.

It is trying to load the config xml file. So you should put it in your class path. Of course, run.demo should have done that already.

Look at your XML file; it is probably corrupted. Happened to me too when I tried to open it with notepad.
