hello ron, until today we didnt experience any problems with the compression. nonetheless we didnt even evaluate the compression, we are just using it: i tested it for simple communication, but we dont know the amount of data that is reduced by compression for our application actually. well, there is no time for this these days, but if we do a review or meet any problems, i will let you know. thanks for your attention. regards robert View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=4179261#...
