Please be serious...I asked for some help or ideas :( I would say the suggestion by Ronald was spot on. Tomcat will happily handle HTTP over TCP sockets for you, but if you need to work on TCP sockets without HTTP, then Tomcat will not be of any help (or perhaps you could write your own listener class, but that could be quite an undertaking). So far you haven't told any reason for use of Tomcat at all, perhaps there is one, but you're the only one of us who knows about it. If your scenario is that you have some data service which you need to expose both over some custom XML over TCP implementation and via HTTP, then perhaps your application structure should be such that there is one application that handles the actual XML data service (so provides the XML-over-TCP scenario), and would then satisfy the needs of this third-party app. Then, to satisfy the needs for the HTTP interface, you would write the requisite servlet code to be run on Tomcat which would likewise get its data using the same XML-over-TCP interface that the server already provides. Or perhaps you do it the other way around (esp. if you already have the HTTP part running (and it is actually needed). You'll write something that can accept the XML-over-TCP, and will make the appropriate HTTP requests to get the required data from the service already running on Tomcat. If, however, the need is just for the XML-over-TCP solution, without any HTTP interface needed now or in the foreseeable future, then just drop Tomcat, and write the code that is needed. I trust there are many good libraries and frameworks to help in building a good custom socket server. Or then you can just write everything right to the core Java APIs. -- ..Juha - To unsubscribe, e-mail: users-unsubscr...@tomcat.apache.org For additional commands, e-mail: users-h...@tomcat.apache.org

2009/11/20 Karthik Nanjangude karthik.nanjang...@xius-bcgi.com A 3rd party Client S/w of C++ sends an XML string over socket This socket is be defined and read by *Process* of web application OK, so you're trying to get Tomcat to do something it's not designed to do: handle incoming TCP connections that are not HTTP connections. This will be a lot of work. It's like trying to drive a car along a river instead of a road... sure, you can adapt the car to do that, but it might be cheaper to get a boat! In this case, it might be cheaper to get a socket server. What are the goals for performance and response time to the C++ client? Can you use something like Apache MINA (http://mina.apache.org/) to write yourself a small server that accepts the incoming XML from the C++ client, then wraps it in a HTTP request and sends that HTTP request to Tomcat? - Peter
