    Architecture Problem

    Hi all,

    I've been a Notes developer for years but I am trying to move into the J2EE
    world.

    Essentially I want to capture data from a web form, format the data into an
    XML stream, send the stream to a server, receive the response and display in
    the browser.

    I've broken it down into parts while I am learning. I've created the form in
    a JSP, I click a button and it creates the XML file, I then manually run a
    java program which sends the file to a remote server, I receive the response
    and then manually display in the browser.

    OK, so now I want to automate this and separate the presentation from the
    business logic etc, which is where I'm stuck. Should I use a Java Bean, EJB,
    a Servlet or some other way to take the form data and create the XML stream
    and send to the server? Is a JSP page the best thing to use for this?

    Any advice is greatly appreciated.

    Regards,

    Michael

      I'm not sure I understand how you want it to work.

      presumably you are clicking a button on the browser to build the xml, so how
      does it get it into a file?

      it's no good having a java program to send the file to the server if you
      want it to run on a web client

          Re: Architecture Problem

          I create the file from the button click, but what I want to do is from the
          button click use a template of the xml request file, read the template in
          using DOM then write the data from the fields into the DOM representation
          and then send that as a stream to a remote server. My problem is what should
          I use to do this, ie. Am I better to use a servlet to parse the template and
          write the data in and send the stream to the server or would an EJB be
          better or am I going about this the wrong way.

          Thanks Michael.
