Java EE (Java Enterprise Edition) General Discussion

Hi everybody,

I have a first servlet (AGSenderServlet) sending a file to a second one (AGReceiverServlet). This second servlet I'm receiving a file and then redirect to a JSP page. But I'm getting the following exception:

13-Sep-2010 13:20:42 org.apache.catalina.core.StandardWrapperValve invoke
SEVERE: Servlet.service() for servlet AGSenderServlet threw exception
java.io.IOException: Received HTTP status code 302
        at AGSenderServlet.doGet(AGSenderServlet.java:43)
        at javax.servlet.http.HttpServlet.service(HttpServlet.java:617)
        at javax.servlet.http.HttpServlet.service(HttpServlet.java:717)
        at org.apache.catalina.core.ApplicationFilterChain.internalDoFilter(ApplicationFilterChain.java:290)
        at org.apache.catalina.core.ApplicationFilterChain.doFilter(ApplicationFilterChain.java:206)

....

I've looked on internet and apparently the error 302 is linked to response.sendRedirect().

Here is my code:

public class AGReceiverServlet extends HttpServlet {
	public void doGet(HttpServletRequest request,
            HttpServletResponse response)
	throws ServletException, IOException {
	    // Create a factory for disk-based file items
		DiskFileItemFactory factory = new DiskFileItemFactory();

	    // Create a new file upload handler
		ServletFileUpload upload = new ServletFileUpload(factory);
		String realPath = this.getServletContext().getRealPath("sync/in");
		List items = null;
				try {
					items = upload.parseRequest(request);
				} catch (FileUploadException e) {
					e.printStackTrace();
				}
				// Process the uploaded items
				Iterator iter = items.iterator();

				try {
					String fileName = "blabla";
					while (iter.hasNext()) {
						FileItem item = (FileItem) iter.next();
						// Process a file upload
						if (!item.isFormField()) {					
							fileName = item.getName();
							long sizeInBytes = item.getSize();
							//Write to File
							if (fileName != null) {
						        fileName = FilenameUtils.getName(fileName);
						    }
							File uploadedFile = new File(realPath);
							if (!uploadedFile.exists())
								uploadedFile.mkdirs();
							uploadedFile = new File(realPath+"/"+fileName);
							
							item.write(uploadedFile);
						}
					}

					System.out.println("http://"+request.getServerName()+':'+request.getServerPort()+"/upTool/filereceived.jsp?filename="+fileName);
					String redirectURL = "http://"+request.getServerName()+':'+request.getServerPort()+"/upTool/filereceived.jsp?filename="+fileName;
					response.sendRedirect(redirectURL);					
					
				} catch (Exception e) {
					e.printStackTrace();
				}								
	}
	
	public void doPost(HttpServletRequest request,
            HttpServletResponse response)
	throws ServletException, IOException {
			doGet(request, response);
	}
}

The file received is saved properly and is ok.
Using print out I have discovered that it was the running the whole code but not the code in filereceived.jsp (the JSP of the sendRedirect() ).
I have tried the url used in the sendRedirect() and it works ok.

Any idea?


Cheers.
