Not to bug you with the specifics of Jini, but suffice it to say there is 
some real hairy stuf with classloaders, codebase, rmiregistry etc etc..
I kept getting a ridiculously vague Socket exception : Client closed 
connection when trying to register a Jini listener.
I finally solved my problem by re-installing Tomcat in a directory 
containing no spaces. Someone, somewhere, used the absolute directory path 
to contruct a URL, and I guess this came from CATALINA_HOME or 
CATALINA_BASE, and since it wasn't properly urlencoded, it fails.
The failure gives NO hint whatsoever of where, why the problem occured, so 
my advice is, if yo're having unexplained problems,just TRY it.
Beware, it's not only the Program Files with an offending space, some 
genius at Apache decided to use Tomcat 4.1 as well. At least the Unix
package was created with a bit more sense.
All problems were solved simply by re-installing to a directory path 
without any spaces.

Hope this helps some of you.
Others, if yo're interested, I can send you the old stack traces, but
they're really vague.

Cheers.

We get that error in one custom JSP tag in our app.  We see it out of the 
blue with no particular pattern.  We have a lot of JSPs and custom tags but 
the exception only gets thrown in one tag, albeit the most complex 
one.  The error occurs in the same app in non-Tomcat environments as well, 
eg. w/i JDeveloper, Websphsere (before we dumped it for Tomcat)...all Win2k 
though.  I was never able to find the root cause, but it doesn't seem to 
affect the application, ie. requests and responses are still handled ok. I 
hate to see an unresolved error pop up like that, but researching it 
basically resulted in the fact that many things can cause it. Like you 
said, it is vague.

Unfortunately, this is a JDK limitation (the URLs are not properly 
encoded, so there are RMI problems with spaces in paths).
