Hello, I am in a very bad position. I have an application that two jboss'es makes EJB3 calls to each other. I see that the data going forth and back takes up a lot of bandwidth causing a bottleneck that my system suffers. I saw a previous post of about CompressingMarshaller and CompressingUnMarshaller and wanted to give it a try. I was so happy with the result in the beginning. But my happiness turned into sadness after some time. Because, I see in the logs errors like "not in GZIP format" on the server side and "254/0/62 (random number), wrong version, version 1,2 supported" like messages on the client side. This might be just a small issue in the way related (Un)Marshallers work. We would really appreciate any help on the issue. I had dived into the source before and did indeed submited couple of fixes to EJB3 and remoting project. If I am given any directions, I might help solve the problem for all. Thank you and once again, I request your immediate help on the issue. Regards, Hasan Ceylan View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=4035290#...
