How to create a file in the server?

Question

Hi,
I'm making a webservice that has to generate a XML file, sign it using another webservice and return this XML. The problem is that i don't know how to create the file in the server throught webservice.
I use this code in the webservice to generate the XML and after I return the XML to client in a byte[]
     static void outputDocumentToFile(Document myDocument, String path) {
        //setup this like outputDocument
          try {
               // XMLOutputter outputter = new XMLOutputter("  ", true);
               XMLOutputter outputter = new XMLOutputter();
               //output to a file
               FileWriter writer = new FileWriter(path);
               outputter.output(myDocument, writer);
               writer.close();
          } catch(java.io.IOException e) {
               e.printStackTrace();
    }But the file is generated in the client-side, how can I generate the file in the server-side?
Thanks very much.

Well the File object doesn't create a file it's simply an abstract representation of file and directory pathnames.
You can try something like this:
<%
try
// get the path to the web server root
// I read somewhere not to use 'getRealPath' for some reason which I
// can't seem to remember :S Hopefull someone can enlighten us :)
String path = application.getRealPath("/project/jsp/demo.txt");
File file = new File(path);
PrintWriter writer = new PrintWriter(new BufferedWriter(new FileWriter(file)));
writer.println("Hello World!");
writer.close();
catch (Exception e)
System.err.println(e.getMessage());
%>
Hope this helps :)
