Request in a SessionBean
[nobr]Hello all !!!
I am developing an application with File Upload, using the Java Creator ONE based in servelet.com. In the example below, the archive is moved successfully, but I would like to have the name of the archive in a SessionBean for use in another page.
Somebody has an idea of as can make this?
They follow the codes:
Anexar.jsp

public class pagina2 extends HttpServlet {
public void doPost(HttpServletRequest req, HttpServletResponse res)
throws ServletException, IOException {
res.setContentType("text/html");
PrintWriter out = res.getWriter();
out.println("<HTML>");
out.println("<HEAD><TITLE>UploadFile</TITLE></HEAD>");
out.println("<BODY>");
out.println("<H1>UploadFile</H1>");
// Parameters can now be read the same way for both
// application/x-www-form-urlencoded and multipart/form-data requests!
out.println("<H3>Request Parameters:</H3><PRE>");
Enumeration enum = req.getParameterNames();
while (enum.hasMoreElements()) {
String name = (String) enum.nextElement();
String values[] = req.getParameterValues(name);
if (values != null) {
for (int i = 0; i < values.length; i++) {
out.println(name + " (" + i + "): " + values);
}
}
}
out.println("</PRE>");
// Files can be read if the request class is MultipartWrapper
// Init params to MultipartWrapper control the upload handling
if (req instanceof MultipartWrapper) {
try {
// Cast the request to a MultipartWrapper
MultipartWrapper multi = (MultipartWrapper) req;
// Show which files we received
Enumeration files = multi.getFileNames();
while (files.hasMoreElements()) {
String name = (String)files.nextElement();
String filename = multi.getFilesystemName(name);
String type = multi.getContentType(name);
File f = multi.getFile(name);
out.println("name: " + name);
out.println("filename: " + filename);
out.println("type: " + type);
if (f != null) {
out.println(" | length: " + f.length()+"\r");
out.println("File Uploaded Successfully");
}
out.println();
}
}
catch (Exception e) {
out.println("Could not upload file/files");
out.print(e.getMessage());
//out.println("<PRE>");
e.printStackTrace(out);
//out.println("</PRE>");
}
}
out.println("</BODY></HTML>");
}
}
