NoClassDefFoundError: $Proxy12
Hi there,
My setup:
machine A with jdk 1.4, jboss 2.4.0+tomcat 3.2.3,
machine B with jdk 1.3.1, same jboss+tomcat
On machine A I run a servlet which tries to lookup
a bean on machine B. The ear is deployed correctly.
When I run a class on machine A from the commandline
which does the same as the servlet, it works fine.
When the code is executed from within the servlet,
I get this stacktrace:
[Default] DEBUG : 2001/09/21 21:54 [m3u] looking up StreamManager

......
I checked via port 8082, MBeanView, and the beans are
correctly deployed and their classnames are $ProxyX where is is 4,6,7,8, not 12 as stated in the exception.
Cannot find any class with name $Proxy12 on machine B's environment..
I have a jar that contains all the project's classfiles, including the beans, interface and home interface files. So that's not the problem (or I must have done something wrong..) That jar is in the WEB-INF/lib directory of my servlet zone.
Any ideas?
PS: I create a new InitialContext with the 3 properties
in the jndi.properties file, with the ip adress of Machine B (on machine A). tcpdump shows that there indeed are connections made to machine B from machine A...
Thanks in advance for any help.
