Cannot lookup LogicalLockingFactory from custom SFTP Adapter

Question

Hi,
We developed an SFTP Adapter on a clustered Advanced Adapter Engine.
When we try to lookup the LogicalLockingFramework, we get a ClassCastException and the proxy Class is missing the Interface LogicalLockingFactory.
We use the following code for the lookup:
LogicalLockingFactory lockingFactory = null;                    
lockingFactory = (LogicalLockingFactory) new InitialContext().lookup(
          LogicalLockingFactory.JNDI_NAME);
Does anybody have an idea, wht the problems could be?
Thanks in advance,
Gernot

Hi Gernot,
i think you are right in this forum.
You receive this ClassCastException probably because the class loader which tries to load the class is not application classloader. I suggest change the class where you change the classloader.                                                                               
So you should change the source like this                                                                               
ClassLoader oldClassLoader =                                                                  
Thread.currentThread().getContextClassLoader();                                               
Thread.currentThread().setContextClassLoader(this.getClass().getClassLoa                      
der());                                                                               
try {                                                                               
//Perform the lookup here                                                                               
} finally { // this step is very important!                                                   
   Thread.currentThread().setContextClassLoader(oldClassLoader);                                 
It is very important to return back the original contextClassLoader when the lookup finishes.                                                  
Best regards,
