JSP refresh from servlet.

Hi everyone
I'm creating a web application that is a combination of jsp pages and servlets.
On one of the jsp pages I add contact details of a person in a form, then when submitted it goes to the servlet which adds the new contact into the database,
after the servlet entered the data it redirects to the ContactList.jsp page, but it doesn't show the newly created user, I need to refresh the page manually to see the users.
How can I from the servlet when I redirect to the ContactList.jsp page, refresh the ContactList.jsp page to show the newly created contacts well?
Here is the servlet which gets called when I submit the jsp form.
package contacts;
import javax.servlet.*;*
*import javax.servlet.http.*;
import java.io.*;*
*import contacts.*;
public class NewContactServlet extends HttpServlet
     public void doPost(HttpServletRequest req, HttpServletResponse res) throws ServletException, IOException
          res.setHeader("Expires", "Tues, 01 Jan 1980 00:00:00 GMT"); //no cache allowed
          Contacts contacts = new Contacts();
          ContactsData contactsData = new ContactsData();
          contacts.setContactName(req.getParameter("contactName"));
          contacts.setCompany(req.getParameter("companyName"));
          contacts.setWorkNumber(req.getParameter("workNum"));
          contacts.setCellNumber(req.getParameter("cellNum"));
          contacts.setFaxNumber(req.getParameter("faxNum"));
          contacts.setEmail(req.getParameter("email"));
          contacts.setCountry(req.getParameter("country"));
          contactsData.addContact(contacts);
          res.sendRedirect("ContactList.jsp");
}

Hi manuel.leiria
Here is my code for refreshing the jsp, it is working.
Just tell me what you think, if it's the right way.
The servlet that sets the attribute
          session.setAttribute("contactsSession","add");
          res.sendRedirect("ContactList.jsp");The jsp page that gets the page.
          <%
          String refreshSession = (String)session.getAttribute("contactsSession");
          if(refreshSession != null && refreshSession.equals("add"))
               %>
               <body onload="window.location.reload(true);">
               <%
               session.removeAttribute("contactsSession");
          else
               %>
               <body>
               <%
          %>

Output byte[] (image) to JSP page from Servlet - not working - why??

I'm testing some new code in my servlet. I'm changing the method I use for pulling an image from the db (which is stored in a Blob column) and then displaying it in a Jsp page via <img src="go.callServlet">
The new way works up until the code that outputs the image (bytes).
Here's a snippet of the code -
               rs = stmt.executeQuery("Select image from images");
               rs.next();
               Blob blobimage = rs.getBlob(1);
               int index = 0;
            in = blobimage.getBinaryStream();
            BufferedImage orig = ImageIO.read(in);
            //resize image
            GraphicsConfiguration gc = getDefaultConfiguration(); //calls method in servlet
             BufferedImage image = toCompatibleImage(orig, gc); //calls method in servlet
             final double SCALE = (double)max_Width_Large/(double)image.getWidth(null);
             int w = (int) (SCALE * image.getWidth(null));
             int h = (int) (SCALE * image.getHeight(null));
             final BufferedImage resize = getScaledInstance(image, w, h, gc);
               //convert bufferedimage to byte array
               ByteArrayOutputStream bytestream = new ByteArrayOutputStream();
              // W R I T E
              ImageIO.write(resize,"jpeg",bytestream);
              byte[] bytearray = bytestream.toByteArray();
              bytestream.flush();
              res.reset();
               res.setContentType("image/jpeg");
             while((index=in.read(bytearray))!= -1 ) {
                       res.getOutputStream().write(bytearray,0,index);
             res.flushBuffer();
             in.close();
             //....               I know for a fact that the process of getting the image as a blob, making a BufferedImage from it, having the BufferedImage resized, and then converted into a byte[] array, works! I tested by putting the result into a db table.
I just don't understand why it is that as soon as it gets to the code where it should output the image, it doesn't work. Its frustrating:(
Here's the code I use regularly to output the image to the jsp, works all the time. The reason I've changed the method, is because I wanted to resize the image before displaying it, and keep it to scale without losing too much quality.
rs = stmt.executeQuery("Select image from testimages");
               rs.next();
               Blob blobimage = rs.getBlob(1);
               int index = 0;
            in = blobimage.getBinaryStream();
              int blob_length = (int)blobimage.length();
              byte[] bytearray = new byte[blob_length];
              res.reset();
              res.setContentType("image/jpeg");
             while((index=in.read(bytearray))!= -1 ) {
                       res.getOutputStream().write(bytearray,0,index);
             res.flushBuffer();
             in.close();
//...Can someone shed some light on this trouble I'm having?
Much appreciated.

I hate to bother you again BalusC, but I have another question, and value your expertise.
With regards to using the BufferedInput and Output Streams - I made the change to my code that is used for uploading an image to the db, and I hope I coded it right.
Can you please take a look at the snippet below and see if I used the BufferedOutputStream efficiently?
The changes I made are where I commented /*Line 55*/ and /*Line 58*/.
Much appreciated.

How to call JSp from Servlet??

Hello,
I want to call JSP page from servlet.I am using Visual Age For java 3.4. What is wrong in my code??
if (userExists) {
f.setErrors("userName","Duplicate User: Try a different username");
getServletConfig().getServletContext().
getRequestDispatcher("/jsp/forms/retry.jsp").
forward(request, response);
I am not able to get the o/p. Pls help.

I can't see anything obvious, but did you take any steps towards doing output before this code (like openning an output stream)?
Not clear what f.setErrors does - presumably stuffs the error message in an attribute of the request.

Pass data from servlet to jsp using sendRedirect

Hi,
I am passing data from servlet to jsp using forward method of request dispatcher but as it doesn't change the url it is creating problems. When ever user refreshes the screen(browser refresh) it's re-loading both servlet and jsp, which i don't want to happen. I want only the jsp to be reloaded.
Can I pass data from servlet to jsp using sendRedirect in this case. I also want to pass some values from servlet to jsp but without using query string. I want to set some attributes and send to jsp just like we do for forward method of request dispatcher.
Is there any way i can send data using attributes(without using query string) using sendRedirect? Please let me know

sendRedirect is meant as a true redirect. meaning
you can use it to redirect to urls not in your
context....with forward you couldn't pass information
to jsps/servlets outside your own context.Actually, you can:
getServletContext().getContext("/other").getRequestDispatcher("/path/to/servlet").forward(request, response)I think the issue here is that the OP would like to have RequestDispatcher.forward() also update the address in the client's browser. That's not possible, AFAIK. By the time the request is forwarded, the browser has already determined the URL of the servlet, and the only I know of way to have the browser change the URL to the forwarded Servlet/JSP is to send a Location: header (i.e. sendRedirect()). Remember that server-side dispatching is transparent to the client. Maybe there's some tricky stuff you can do with JavaScript to change the address in the address bar without reloading the page?

How to invoke a jsp page from java which does not use Servlets?

Hello,
I am working in Documentum. I am trying to invoke a jsp page from another java page which does not use Servlets.
I tried doing this by just instantiating the java class related to the jsp page from my present java class.In my java class related to the jsp page, I have defined onInit() and onRender() methods.
Now, I am trying to call the jsp page from my present java class by just instantiating the java class related to the jsp page. This throws a java.lang.NullPointerException.
Any comments or suggestions on this.Any help would be appreciated.

Hello,
Thanks for the reply. One important thing I forgot to mention. I am also using xml component.And?
As this is the standard way used for coding in Documentum, I do not want to use Beans.Well, JSP's should, in and of themselves, contain no functional code. It should all be only display.
Without that is it not possible?What did I say? I said,

Error message from servlet to jsp

Hi again,
I have servlet and check error on this servlet then i would like
to send error message to jsp page.Every error message will send to
same JSP page.So JSP must receive message from Servlet.Can i do this?
Please give me details and some sourcecode.I will appreciate for your helps.

you could do something like this..
request.setAttribute("error", stringErrormessage);
Then in the jsp just do
<%= request.getAttribute("error") %>
That will print an errormessage.
Basically, by setting anything on the request and then redirecting to that page you cn display it...

Getting to next JSP from Servlet

I am getting a 404 when I try to redirect from my servlet to an error page. The code that I am testing is....
catch (SQLException es)

public static final String ERROR_PATH = "/Jsp/error.jsp";
My JSP pages are located at the root...

Can anyone point me in the right direction....Thanks

I tend to use a utility method called redirectToResource in particular to redirect from any servlet to any JSP :

How to send a message from Servlet to JSP

Dear all,
I have JSP, with JavaScript (AJAX). If the user click on the button, the text will be sent to a Servlet parsed by doGet() and the user get a response to his input, without reloading a page.
How can I send a message to the users (JSP) from Servlet, if he didn't clicked any button and to other visitor of the page also? Is it possible? I think like a chat, the server sends a message to all users who are subscribed.
I don't know, what should I get from user, maybe session, that I could send him personal or common messages in his textarea. I should also invoke some JavaScript function to update his page. I have met some chats, you don't do nothing and get messages. It is also without a JavaScript timer, which invokes doGet() method. Asynchronous, only when there is a message.
Please help me with a problem.
Thanks in advance.

Hai ,
You can send any message through response.sendRedirect();
here is the coding try it
import java.io.*;
import javax.servlet.*;
import javax.servlet.http.*;
public class SimpleCounter extends HttpServlet {
public void doGet(HttpServletRequest req, HttpServletResponse res)
throws ServletException, IOException {
res.setContentType("text/plain");
PrintWriter out = res.getWriter();
String username="java";
res.sendRedirect("http://localhost:8080/yourprojectname/jspfile.jsp?username="+username);
}

Problem in calling JSP page from a servlet

can anyone please tell me how to call a JSP from servlet?
My code is:
ServletContext sc = this.getServletContext();
                                             RequestDispatcher rd = sc.getRequestDispatcher("./Welcome.jsp");
                                             if (rd !=null)
                                                  try
                                                       rd.forward(req, res);
                                                  catch (Exception e)
                                                       sc.log("---------------Problem invoking JSP.------------------", e);
I n the browser when i call this servlet it gives error-404.
NOT Found.
please help.

I would try to change "./Welcome.jsp" to "/Welcome.jsp". I'm not sure what that period will do.
Are you able to access that JSP directly from your browser (even if it's not designed to be accessed that way)? If not, then you have some other problem.
When you say you get a 404 when you access the servlet, is that when you access the servlet, or when it tries to forward to the JSP? If you get the 404 when you access the servlet, perhaps your servlet-mapping to the servlet is invalid.

How to pass a object of JSP to a servlet called from JSP

Hi,
I am trying to display an image in the JSP through html image tag. I am using Struts Action class to get the image data from the database through a Session EJB. I am getting a byte array for the image retrieved from the database.
To display the image I need to call a servlet from the JSP from the image tag like this.
<html:img src="imageservlet" border="0"/>
But I need to send the image byte [] array data which is available with the JSP to the servlet to build image. I have a bean object with the JSP which holds the image byte []. The servlet should receive the bean object and will use the byte [] and build the image to be displayed.
My query here is how to send this bean object to the servlet which is getting called from the JSP as shown above.
Thanks in advance.

Applet in jsp from servlet, but error: ClassNotFoundExcep

The problem that I'm having is already mentioned a couple of times in this forum, but unfortunately I haven't found a solution, in thread http://forum.java.sun.com/thread.jspa?forumID=33&threadID=239405 is proposed solution but it's not working for me.
I'm developing a project in IBM's Websphere Developer Studio 5.1.1. and JRE that I'm using for this project is 1.4.2. I have created servlet "CompanyDocument.java" and applet "SimpleApplet.java". Applet was created as single project and then imported into this one, that means that it's contained in current project as "SimpleAppletPackage.jar". I have placed jar in folder "Applets", Websphere automatically creates folder "simpleAppletPackage" and in it's root complied "SimpleApplet.class".
When I put following code in the jsp page applet works correctly when application is runed.
<APPLET code="simpleAppletPackage/SimpleApplet.class" codebase="Applets" archive="SimpleAppletPackage.jar" width="250" height="250"></APPLET>
But I wanted to create jsp from servlet. So I used this code within servlet:
out.print("<APPLET code=\"simpleAppletPackage/SimpleApplet.class\" codebase=\"Applets\"");
out.print("archive=\"SimpleAppletPackage.jar\" width=\"250\" height=\"250\"></APPLET>");
But I get an error (when running, no error when compiling). The error is copied from Java console:
load: class simpleAppletPackage/SimpleApplet.class not found.

... 9 more
In the same time I'm creating some more code from servlet and it works with no errors and is shown in browser properly (it consists of connection to Oracle, formatting table, and presenting data within that table).
Any idea? I'm totally stuck.

In your browser, look at the HTML code that gets sent to the browser and see if there is something wrong with it.
Specifically, I would look at the code near the <APPLET ..></APPLET> tags, both before and after and look for stray quotes, brackets, or what not.
Finally, I would look inside the <APPLET ...> tag. It appears to me that the output will probably be:
<APPLET code="simpleAppletPackage/SimpleApplet.class" codebase="Applets"archive="SimpleAppletPackage.jar" width="250" height="250"></APPLET>See, you may be missing a space between the "Applets" and the archive=. Try making the second out.print look like this:
out.print(" archive=\"SimpleAppletPackage.jar\" width=\"250\" height=\"250\"></APPLET>"); See the extra space at the start of the output?

Parameter passing from servlet to jsp page

Hi Jaykumar
You should use
<%= request.getAttribute("sting") %> or
${string}
in your jsp. I think you are trying to retrive the parameter instead of attribute.

Passing vectors into JSP from Servlet and passing data back to Servlet

I have been building an MVC application.
It has a controller which instantiates classes and evokes methods to
populate vectors. These vectors are then passed into a JSP. This part of the application works fine.
What I am having trouble with is a new JSP I have designed; this will
display the data that is actioned by the FORM action. This is actioned
based on the Search criteria entered by the user. Based on this a further vector is populated and brought back to the JSP as a vector
and this is rendered via the TABLE tag. Again this works fine.
Against each of the rows displayed, I have a print checkbox which can be checked by the user. On checking the records they want to print, they should then hint a Print button which should go back to the Servlet and print the data. THIS IS WHERE I HAVE THE PROBLEM. On going
back to the servlet the checkbox values are not displayed, rather
the values that initially populate the JSP. How do I get these new values back into the vector and hence accessible from the Servlet.
Any help with be very much appreciated.

Thanks for this.
Just to clarify I am not using Struts.
What I am having difficulties with is the fact that:
I can't get the checked values back to the Servlet - they keep the values they have in the bean - so as part of instantiating the bean class I set the value of the item to 'off'. The user will then check
the checkbox which should presumbably set the value to 'on'. This isn't happening because the setter method of the bean is not evoked again
because I don't come into this JSP again - the Servlet has finished here
and now needs to print the records. It can't do this because as
far as it is concerned nothing has changed since it last passed through
the vector to the JSP.
Even when I do the following:
Enumeration paramNames = request.getParameterNames();
String param = null;
while (paramNames.hasMoreElements())
param=(String)paramNames.nextElement();
System.out.println("parameter " + param + " is " +
request.getParameter(param));
what comes back is the valus of 'off' as opposed to 'on'.
The other thing is that 'request.getParameterNames()' only works
with the first record in the vector, i.e. it doesn't fetch any other
records that are rendered in the <TABLE> tag.
In desperation is there anybody out there who can help me.
Thanks

I am going to assume you are using a MVC framework
like Struts or very similar (I am assuming that from
the language you are using).
When the servlet passes the vector back to the JSP
page and you render the HTML that is passed back the
client your Vector is gone. The Vector is not
available at the HTML level that is being viewed at
the browser.
When the user selects the checkboxes and submits the
page (by clicking the print button) the controller
servlet (called ActionServlet in Struts, yours maybe
called something else) forwards the request to the
appropriate JavaBean and Servlet to process the
request. Either the JavaBean has to recreate the
Vector (not recommended) or the processing Servlet can
(better). You can do this by recreating the Vector
from scratch for the HttpRequest parameters or, at the
time of the initial request, saving Vector to a
session and then updating with the data you get back
from the client (again from the HttpRequest
parameters).
Either way you have to work with
HttpRequest.getParameter().

JSP refresh from servlet.
