Apache Mina ExecutorFilter

I am facing a strange issue with apache MINA. I have server application which is based on apache Mina framework. I am using ExecutorFilter at the server side. the application works perfectly on my machine but when I am installing it on client's machine its "throwing exception".

Here is the error I am getting on client's machine:

java.lang.NoSuchMethodError: org.apache.mina.filter.executor.ExecutorFilter.<init>(II[Lorg/apache/mina/core/session/IoEventType;)V

This is how I am referring it in my code-

new ExecutorFilter(1, 100, IoEventType.MESSAGE_RECEIVED)

There are 2 differences I found between my system and client's machine - Java Version ==> My 1.6.0_26 / Client's 1.6.0_24 Operating system ==> my XP SP3/ Client's Windows 2003 server SP 2

Can any one shed any light on any possible solution?

thanks in advance.

Solution

  • In my experience, a NoSuchMethodError (or NoClassDefFoundError, AbstractMethodError) at runtime almost always indicates a library version mismatch. Make sure your client uses the exact same Mina version, and make sure there does not happen to be a second version of the Mina JAR on the classpath confusing things.
