Hi,
If someone wants to take a deeper look... Stack trace at bottom of this post...
Context is a tomcat web-app a la jsp [hence, not using
org.eclipse.equinox.servletbridge];
Snippet of application code (java):
if (!EclipseStarter.isRunning()) { BundleContext ctx =
EclipseStarter.startup( args, null ); }
I can run the jsp, which invokes the aforementioned java code, after starting
tomcat, and all is well;
However, if I restart the web-app (leaving tomcat up and running), I get an NPE
for which the stack trace indicates is deep in the bowels of
EclipseStarter.startup() [noting that isRunning() returned false, which I guess
is correct...
On an aside, I'm not sure how to trap web-app stop/restart to invoke
EclipseStarter.shutdown()... (and other clean up activities) [my ignorance on
that one, presume];
Here's the stack trace:
