I tried to configure compressed remote calls as described in Configuration Guide section 14.2.1.

See: http://www.redhat.com/docs/manuals/jboss/jboss-eap-4.2/doc/Server_Configuration_Guide/The_EJB_Server_Side_View-Detached_Invokers___The_Transport_Middlemen.html.

I changed jboss-service.xml to use a CompressionClient/ServerSocketFactory:

<mbean code="org.jboss.invocation.jrmp.server.JRMPInvoker" name="jboss:service=invoker,type=jrmp,socketType=CompressionSocketFactory">
 <attribute name="RMIObjectPort">4445</attribute>
 <attribute name="ServerAddress">${jboss.bind.address}</attribute>
 <attribute name="RMIClientSocketFactory">org.jboss.test.jrmp.ejb.CompressionClientSocketFactory</attribute>
 <attribute name="RMIServerSocketFactory">org.jboss.test.jrmp.ejb.CompressionServerSocketFactory</attribute>
 <depends>jboss:service=TransactionManager</depends>
 </mbean>

The CompressionClient/ServerSocketFactory uses a CompressionSocket to wrap the Input/OutputStream of the client-server-socket with a java.util.zip.GZIPInput/OutputStream:

class CompressionSocket extends Socket
{
..
 /*
 * Returns a stream of type CompressionInputStream
 */
 public InputStream getInputStream() throws IOException
 {
 if (in == null)
 {
 in = new GZIPInputStream( super.getInputStream() );
 }
 return in;
 }

 /*
 * Returns a stream of type CompressionOutputStream
 */
 public OutputStream getOutputStream() throws IOException
 {
 if (out == null)
 {
 out = new GZIPOutputStream( super.getOutputStream());
 }
 return out;
 }
..

The configuration is working. The CompressionClient/ServerSocketFactory are used. But i get an exception on the client side when i do remote calls:

java.rmi.ConnectIOException: error during JRMP connection establishment; nested exception is:
