Hello everyone,

I downloaded JBOSS AS 4.2.2 and deploy JBPM ear file on it by jbpm-installer-3.3.0.GA.jar installer.

While installing JBOM by jbpm-installer-3.3.0.GA.jar, I provide the path for  server the path where JBOSS AS is installed.

I am able to start the server and see the JBPM console by " http://localhost:8080/jbpm-console/" URL.

By default, some of the process are available as example.
I tried using the process definition "websale ".

I logged in as manager and create a instance of above process.
When it comes to task named "Create enw web Sale order", we have to provide the values for fields "item,quantity,address".

On providing the data for the above fileds, click on evaluate button ......
Following exception is showing:
"Error completing task: An exception of type 
"org.jbpm.graph.def.DelegationException" was thrown. The message is: Cannot open connection
Closing the database context failed: An exception of type org.hibernate.exception.GenericJDBCException was thrown, with the message: Cannot open connection "

and exception is shown in stack trace as due to non creation of timer.

the atsck trace is as follows:

13:49:49,141 ERROR [GraphElement] action threw exception: Failed to create timer
