I am trying to connect to the default Jetspeed database from a custom JSP tag using Torque. The servers are JBoss and Jetty.
The system throws a JasperException when the following statement is executed:
ServiceBroker broker = TurbineServices.getInstance();
(The stack trace is reproduced at the end of this email.)
However, using Eclipse debugger at that point yields a valid object for the expression on the right.
I encountered the same problem when trying to get RunData within the same JSP class. The problem is circumvented by using reflection.
Looking at the custom JSP classes that came with Jetspeed, I found that RunData can be retrieved directly without reflection. The same statement when pasted into my JSP class failed to run (unless I use reflection):
RunData data = (RunData) pageContext.getAttribute(JspService.RUNDATA, PageContext.REQUEST_SCOPE);
May I know if anyone has encountered similar problems?
Thanks!
Regards, Yong Bing
