Description Matt Cross 2006-04-17 18:45:09 UTC 
I have a web application that uses RMI.  This application works fine
when my app is either deployed in exploded form or when I deploy as a WAR
but set unpackWars="false".

When I set unpackWars="true" I get EOFException each time I call
Naming.lookup(url) (where url is something like //localhost:9222/FooObject)
Comment 1 Yoav Shapira 2006-04-18 13:10:30 UTC 
Stack trace?  JDK version?

Also downgrading from critical, as you noted alternative deployments work.
Comment 2 Matt Cross 2006-04-18 13:12:34 UTC 
JDK 1.5.0_06
Stack trace on it's way...

Comment 4 Matt Cross 2006-04-18 13:17:08 UTC 
Again this seems to only affect RMI and only happens when you have a war file 
that tomcat unpacks but this happens to be the way most of our apps are 
deployed.
Comment 5 Yoav Shapira 2006-04-18 13:26:20 UTC 
Understood.  Any chance of a simpler test app to show this?  We don't have
access to the com.endeca classes, and I don't particularly feel like setting up
a test Axis server either... Maybe a one-class webapp that just tests
marshalling / unmarshalling via RMI?
Comment 6 Matt Cross 2006-04-18 13:31:30 UTC 
I'll try to write you a sample app.  If you get to it first simply ignore the 
endeca and axis stuff.  Just try to make an RMI request from a servlet.
Comment 7 Yoav Shapira 2006-04-18 13:37:53 UTC 
The chances of me getting to it first are nil ;)
Comment 8 Yoav Shapira 2006-12-24 19:05:15 UTC 
Ping?  Still the case with Tomcat 5.5.20?
Comment 9 Mark Thomas 2009-07-07 11:56:20 UTC 
I can't repeat this with the latest trunk (with a 1.6 JVM) or with the latest 5.5.x (with a 1.5 JVM).
