Hi Together,

i wrote a CustomServlet to handle uploads from a flashcomponent. Now i am using Componetnt.getInstance(...) to get my seam component which should manage this all. But with every call i get a new instance. I'm was looking for a solution the last 2 days and i despair. Before i forget it, i send my jsessionid to the servlet as a get parameter.

Hope you can help me, here is my servletcode:

package com.rollertreffen.service;

import java.io.*;

import javax.servlet.*;
import javax.servlet.http.*;

import org.apache.commons.fileupload.*;
import org.apache.commons.fileupload.servlet.*;
import org.jboss.seam.*;

public class UploadServlet extends HttpServlet {
    private static final long serialVersionUID = 1L;

    @Override
    protected void service(final HttpServletRequest req, HttpServletResponse res)
            throws ServletException, IOException {
        req.setCharacterEncoding("UTF-8");
        
        getUploads(req);

        res.setContentType("application/json");
        PrintWriter out = res.getWriter();
        out.println("{empty}");
        out.close();
    }
    
    protected void getUploads(HttpServletRequest req) {
        final String sessionId = req.getParameter("jsessionid");
        System.out.println("Session ID: " + sessionId);
        final ServletFileUpload upload = new ServletFileUpload();
        try {
            PictureManager pms = (PictureManager) Component.getInstance("pms", ScopeType.SESSION);
            for (FileItemIterator it = upload.getItemIterator(req); it.hasNext();) {
                final FileItemStream item = it.next();
                System.out.println("Fieldname: " + item.getFieldName());
                final byte[] uplBytes = getByteArray(item.openStream());
                System.out.println("UPLOAD: " + uplBytes.length);
                if ("form-demo:picture1".equals(item.getFieldName())) {
                    pms.addFile(uplBytes);
                }
            }
            pms.upload();
        } catch (FileUploadException e) {
            // TODO Auto-generated catch block
            e.printStackTrace();
        } catch (IOException e) {
            // TODO Auto-generated catch block
            e.printStackTrace();
        }
    }
    
    protected byte[] getByteArray(InputStream is) throws IOException {
        final ByteArrayOutputStream bos = new ByteArrayOutputStream();
        final byte[] buffer = new byte[32768];
        for (int read; -1 != (read = is.read(buffer));) {
            bos.write(buffer, 0, read);
        }

        is.close();
        bos.close();

        return bos.toByteArray();
    }
    
}

Best regards, Steffen
