Hi guys,

I'm a newbie in JBoss. I've just downloaded and tried JBoss Developer Studio and follow the TicketMonster tutorial.

But I'm stuck in running h2console.

I run successfully jboss-as-greeter at http://localhost:8080/jboss-as-greeter/. Then I try to deploy h2console.

After copying h2console.war to JBOSS_HOME/standalone/deployments/, I access to http://localhost:8080/h2console/, but it gave me below error:

HTTP Status 500 -

type Exception report

message

note The full stack trace of the root cause is available in the JBoss Web/7.0.13.Final logs.

So pls help me fix this error.

Thanks for your helps!
