cPath plugin for Cytoscape 2.1 using Webstart

[Mack]

I'm trying Cytoscape 2.1 using webstart and the cpath plugin. However
I'm running into problems. I can get it all to work when I run things
locally and can specify a plugins directory with a --JLD argument. The
problem comes when I run this through an web server. The --JLD tag no
longer works. I've been told to try using the -rp argument with the
classpath for the main plugin class. Well, that was simple enough
considering the single class in the cpath.jar. However I'm getting the
following expection when I try to run everything.

Caused by: java.lang.NoClassDefFoundError:

Any help is appreciated resolving this issues.

Hi Mack,
Are you signing your cpath plugin jar? Did you try Googling through
the Cytoscape discussion list? There is quite a bit of discussion
there about Cytoscape and webstart.

All my jars are signed properly and everything works if I run my .jnlp
as a local file. The problem exists when I distribute the file through
use of a web server. Even then I can get other plugins to load
properly, but not cPath. It can't find one of the classes, which is
present in the data-aux jar.

Since my issue was specifically pertains to loading the cPath plugin I
figured I'd try here instead of the Cytoscape group.

thanks,
