Propagating errors from a PlugIn to a jsp

Is there any way for a PlugIn to get exception messages up to a jsp?

I have a PlugIn that initialises a system object that does important 
work. If the PlugIn can't start the background process running, I'd 
like to use <html:errors /> in the index.jsp, so when Tomcat starts, 
the first page will display any errors the PlugIn encountered.

thanks,
Alistair

thanks for that Erik,
I think I'll bung some Bean methods into the PlugIn and do a small tag
library for JSPs to use. I don't want any code in the JSP, just tags.
thanks,
Alistair

Your plugin could set application scope attributes using any Exceptions 
it encounters during the init method. Then your requested JSP (or setup 
Action) could grab those and iterate them.
