Errors starting JBoss with jBPM

Laura delli Paoli Apprentice

Hello everybody,

I installed JBoss using the jbpm installer with the attacched build.properties file and the ant command ant install.demo.noeclipse.

Then I started Eclipse IDE, with the JBoss tool and the drools tools installed and I added a new server, with the attached  standalone.xml configuration file  (i.e. the one privided in the jbpm installer) .

When I start the server, I get many errors (see attacched server.log) and a while after I open the jBPM console I get a RequestException.

Can anyone help me fixing these errors or provide a working configuration file?

 

thanks

Laura

    It looks like there is not data base started when you start application server. i would recommend to use ant start.demo.noeclipse to complete your installation rather than importing the app server into eclipse and starting it from there.

    Thank you Maciej,

    If I run: ant start.demo.noeclipse both http://localhost:9990/console/ and http://localhost:8080/jbpm-console/ are Ok!

    Anyway I really need to use a custom configuration file and I'd prefer to run applications into Eclipse, can you help me?

    first of all make sure that data base is running, for instance start it before you start app server from within eclipse (ant start.h2). See if that is the only requirement in your case to be able to run the tooling.

    Thanks, now I can access both consoles, but I still get an error:

    Have you built the packages in Guvnor? If so, can you access them when using ant start.demo.noeclipse?

    to have packages (processes, rules, etc) available to jbpm console they need to be built in Guvnor. Go to package, edit tab - there is build package button once it builds successfully you should be able to see them in console.
