Hi,I would like to replace a particular legacy component in our system with a re-written Java component running on tomcat. The old component communicates with other components over TCP via a proprietary 3-step protocol. As other components in the system are replaced, I would like to move the to a combination of SOAP and HTTP Posts of XML files for implementing this communication. In the mean time, however, I would like my application to continue to support the old protocol.1) It seems that the default behaviour of tomcat is to work with HTTP requests. Is there a way to get it to accept a proprietary protocol over TCP (i.e. no HTTP Headers)?2) Additionally, i know how to build a stateless servlet in Tomcat. This, however, will need to be a statefull one. What's the best way to keep track of the data for all the active sessions?Thanks in advance,kingraine _________________________________________________________________ Create the ultimate e-mail address book.
