problem with ImageGen plugins

[Bob Paige-2]

I'm having some trouble getting the ImageGen plugins to work when deployed
on our Sun server.

Deployed locally (WinXP) under tomcat, the plugins work fine. When I deploy
exactly the same .war file to Sun I get

SequencePlugin failed: org.nascif.jspwiki.plugin.imagegen.ImageGenError:
Error generating graph - java.lang.NullPointerException

I see no other error messages in the catalina log file, and I don't have
permission on the server to adjust log levels.

Could this be a problem with temp directories? (I'm guessing). Does anyone
know how this works internally, or have experience with this type of error?

Bob,

I personally have not used this plugin, it is also not a core plugin.
But the source is available at http://www.jspwiki.org/wiki/ImageGen

If you have a stacktrace, that might help us a little further......

regards,
Harry

Harry,

Thanks for the pointer; I didn't realize the ImageGen sources were there.

My problem is further complicated in that our IT department thus far won't
allow me to remotely debug the problem (they control the server) and it
doesn't appear when I run the exact same .war file locally. Also, there is
no stack trace; the code literally logs the error message I included before
and then throws a new exception.

I'll see if I can put some pressure on IT, but I don't have much leverage at
this point :(

If you are using GraphViz it must be separately installed on the server
and a path to it's binary must be in the jspwiki.properties file.

I mentioned it in a separate thread, but I eventually found the problem: the
upload directory needed to be set.
