InvalidClassException - please help

[pepek]

Hi,
I just downloaded jboss 3.0.4 and when im trying to lookup jndi context by following lines (calling is from servlet)

try {
Object res = myJNDIContext.lookup(name);
} catch (Exception e) {
System.out.println("[ERROR] " + e.toString());
}

then I got this error message:
----------------------------------------------------
[ERROR] javax.naming.CommunicationException [Root exception is java.io.InvalidClassException: org.jboss.invocation.jrmp.inter
faces.JRMPInvokerProxy; Local class not compatible: stream classdesc serialVersionUID=-3713605626489646730 local class serialVersi
onUID=4948756606502181321]
----------------------------------------------------

I use TOMCAT 4.0 and JRE 1.3.1
I suppose there will be a mismash with libraries..

Thanks
Petr

I forgot,

for InitialContext is use this parameters

hashtable_1_1_.put("java.naming.factory.initial", "org.jnp.interfaces.NamingContextFactory");
hashtable_1_1_.put("java.naming.provider.url", "localhost:1099");
hashtable_1_1_.put("java.naming.factory.url.pkgs", "org.jboss.naming:org.jnp.interfaces");
