Problem with two instances on same network
I am developing ServiceMix components, therefore I have ServiceMix installed
and running on my development machine (Machine 1). I need to deploy another
instance of ServiceMix on another machine (Machine 2) so that other
developers are able to communicate with it for their own development, this
instance will have all of the same components that I have on my machine.
The problem that I am running into is that when I start ServiceMix on
Machine 2 and then attempt to start it on Machine 1, I receive errors over
and over again. The error is:
Error processing incoming broadcast message
Javax.jms.JMSException: Failed to build body from bytes. Reason:
java.io.InvalidClassException: javax.xml.namespace.QName; local class
incompatible: stream classdesc serialVersionUID = -9120448754896609940,
local class serialVersionUID = 4418622981026545151
Why am I receiving this exception and how can I fix it?
If I just want these two instances to run separately, what do I need to do?
Thank you very much for you assistance.
Doug

No, the class is not missing, but maybe it is loaded
from a different jar, and has a different serial UID.
For example, the implementation from Geronimo [1]
does not define the serial UID, so it is generated by the JVM.
[1] http://svn.apache.org/viewvc/geronimo/specs/tags/geronimo-qname_1.1_spec-1.1/src/main/java/javax/xml/namespace/QName.java?revision=487046&view=markup

Sorry for that post, I tried the serialver utility on my MacBook and it came
back with the serial as 4418622981026545151L. It would appear that something
strange is going on. The two boxes that are returning the negative value are
running Linux. Would it be possible that the negative number signifies that
the class is missing?

When I use the serialver utility I get the serial id as -9120448754896609940L
for javax.xml.namespace.QName.
I tested this in two different 1.5.0 JVMs.
I couldn't figure out where the 4418622981026545151 came from

Guillaume,
It seems like that was the problem. I updated both machines with the newest
version and that fixed it.
Thanks,
Doug

Are you running both instances on the same jvm ?
4418622981026545151 is the serialId under sun jdk 5,
but i don't know for the other one. You need to use
the same class for both instances.
