$Proxy33 cannot be cast to com.dsoft.jca.eis.EisConnection

Hi, 

I tried to run the TxConnect Socket Connector
(http://txconnect.sourceforge.net/) on Geronimo 2.1.3, a test servlet gets
the ConnectionFactory, but on the second line below there is an exception:

    ConnectionFactory connectionFactory = (ConnectionFactory)obj;
    Connection connection = connectionFactory.getConnection();
	    
Connection: com.dsoft.jca.eis.EisConnectionFactory
17:05:40,981 ERROR [EisConnectionFactory] Problem when getting a connection
java.lang.ClassCastException: $Proxy33 cannot be cast to
com.dsoft.jca.eis.EisConnection
        at
com.dsoft.jca.eis.EisConnectionFactory.getConnection(EisConnectionFactory.java:69)

	
Anybody an idea what went wrong?

Thanks,
Juergen

Re: $Proxy33 cannot be cast to com.dsoft.jca.eis.EisConnection

Posted by David Jencks <da...@yahoo.com>.

We have some code that tries to imitate DissociatableManagedConnection  
functionality to avoid connection leaks that wraps the Connection from  
the ManagedConnection in a proxy that implements all the interfaces  
the Connection implements.  However EisConnectionFactory is casting  
the connection to EisConnection rather than say IEisConnection... the  
proxy implements all the interfaces but not the class.

We'll have to think about what to do about this.  Perhaps we need a  
flag to turn on this proxying behavior.  Another solution would be to  
patch TxConnector to implement DissociatableManagedConnection, but  
considering the level of activity on that project this may not work  
too well.

I've opened https://issues.apache.org/jira/browse/GERONIMO-4350 to  
track this issue.

thanks
david jencks

Re: $Proxy33 cannot be cast to com.dsoft.jca.eis.EisConnection

Posted by Juergen Weber <we...@gmail.com>.

Hi,

anybody an idea on this?

I tried the connector on Weblogic server 10.3 and Glassfish 2.1 b54, it
works on both.

So I think the problem is with Geronimo. How could I get to the root of the
problem?



java.lang.ClassCastException: $Proxy51 cannot be cast to
com.dsoft.jca.eis.EisConnection
	at
com.dsoft.jca.eis.EisConnectionFactory.getConnection(EisConnectionFactory.java:69)

Thanks,
Juergen
