Subject Re: [S2] Design Advice Needed
Date Thu, 02 Aug 2007 12:14:51 GMT
I suppose there is a lot of other way to generate pdf with struts2. 
Certainly a plugin. But I don't know how it works.

However, to invoke a jsp and get the result in your action, you can use 
a requestDispatcher to obtain the resut of a jsp execution.

Here is something I already done with struts1. I have problems now with 
struts2's request dispatcher. So I don't know if it still work ...

request.setAttribute("param1", valuepram1);
Eventally, had a path to an embeded image :

ResponseWrapper responseWrapper = new ResponseWrapper(response);


responseWrapper).include(request, responseWrapper);

you can use now
byte[] bytes = responseWrapper.getBytes();
to get the file generated by the jsp.

responseWrapper is a simple class like :

public static class ResponseWrapper extends HttpServletResponseWrapper {

         private ByteArrayOutputStream baos = new ByteArrayOutputStream();
         private ServletOutputStream sos = new ServletOutputStream() {
                         public void write(int b) throws IOException {
         private PrintWriter osw = new PrintWriter(new 
                 public ResponseWrapper(HttpServletResponse response) {

                 public ServletOutputStream getOutputStream() throws 
IOException {
                         return sos;

                 public PrintWriter getWriter() throws IOException {
                         return osw;

                 public byte[] getBytes() {
                         return baos.toByteArray();
