[Mav-user] Strange NullPointerException
I am a newbie to Maverick. I wrote a simple webapp to produce a PDF from a JSP page using Docbook XML - XSL:FO (w/ XSLT) - PDF (w/ FOP). This is working fine but now I'm trying to integrate Maverick into our existing webapp. I'm pretty sure I have everything set up the same but when I try to run in in the existing webapp I'm getting a strange NullPointerException: java.lang.NullPointerException at org.infohazard.maverick.util.FakeHttpServletResponse.getOutputAsReader(FakeHttpServletResponse.java:67) at org.infohazard.maverick.transform.XSLTransform$Step.done(XSLTransform.java:186) at org.infohazard.maverick.view.DispatchedViewFactory$DispatchedView.go(DispatchedViewFactory.java:106) at org.infohazard.maverick.view.DocumentView.go(DocumentView.java:52) at org.infohazard.maverick.flow.ViewWithTransforms.go(ViewWithTransforms.java:39) at org.infohazard.maverick.flow.CommandBase.go(CommandBase.java:50) at org.infohazard.maverick.Dispatcher.service(Dispatcher.java:179) at javax.servlet.http.HttpServlet.service(HttpServlet.java:853) Any ideas??

RE: [Mav-user] Strange NullPointerException
This happens when the previous step (or view) never called HttpServletResponse.getOutputStream() or getWriter(). I believe I recently checked in a patch that prints a better error message in this case. Maybe the jsp page is misnamed? I would normally expect that to cause getRequestDispatcher() to return null, but it would explain the problem. What container/version are you using?

RE: [Mav-user] Updates to maverick
The separated param collections and the absolute config path features are checked in. Take a look. I'll get to the remaining issues soon. Jeff From: Schnitzer, Jeff [EMAIL PROTECTED] Separating the three different param collections (controller, view, transform). Allowing file:, http:, ftp: in the maverick config file (and config transform) path. Need to check to see if I can detect absolute vs relative URLs just by creating a URL and checking for MalformedURLException. Oterhwise just explicit checks for those strings will work. Review John-Mason's controller chaining code and figuring out how this can be morphed into a pluggable Controller framework. Adding a link to Roman's Tiers sample. Sorry about the lag. Both work and life switched into high-gear at the same time. Jeff Schnitzer [EMAIL PROTECTED] --- This SF.net email is sponsored by: SlickEdit Inc. Develop an edge.
