Send data from one Java application to another

I have to send an XML-file from one java Application to another.

Currently, it works like this: - Export to local XML-file from application 1 - Import local XML-file in application 2

Now I have to do this via web service(s). Is it possible to create a JAX-WS web service in application 1 that redirects to application 2 with the data needed?

I can send the data (object) as a serialized object, instead of a XML-file. But is this possible? And if so, how?

Both applications are written in Eclipse-Scout.

Thanks in advance.

Solution

  • webservice is simple and usefull if your two apps run on different machines.

    Sending server: use a library for http (post or get)

    1 only keep your file. just use an HTTP / POST. works for text an binary

    2 more simple: if your datas are little text, you can use HTTP / GET (beware of special characters: you can encode them).

    3 if you can put all your datas in one structure (object), just serialize it, put the result in a String, and send it.

    Receiving server:

    if you use tomcat, extend HttpServlet, and get by doPost or doGet

    Or you can use another light http server

    Or soap library (no really need).

    DOPOST/DOGET

    Sending server: HttpURLConnection conn= (HttpURLConnection) url.openConnection(); // etc.

    Receiving server:

    public class MyServlet extends HttpServlet {
@Override
protected void doPost(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException {
String one_parameter = request.getParameter("name_of_parameter");
