Help on jsp:output

I am trying to use the <jsp:output> tag within jdeveloper10.1.2, but it is not included within the tags for JSP in the component pallete, so I keep getting an error. Any idea, pls ?

jsp:output is a J2EE 1.4 JSP 2.0 tag.
JDeveloper 10.1.2 provides only the JSP 1.2 tags.
http://java.sun.com/products/jsp/syntax/1.2/syntaxref12.html
JDeveloper 10.1.3 supports J2EE 1.4 (JSP 2.0).
Some of the JSP 2.0 tags are not in the Component Palette.
jsp:output tag, jsp:invoke and jsp:text tags which are jsp 2.0 tags are not in the Component Palette.

IE don't display JSP output. It pop up download dialong and open Dreamweaver.
I dont' know why, but when run in Netscape is OK
Anyone please help.

Looks like your problem lies by the file associations, i.e. extension of your jsp file (.JSP) is associated in your operating system with DreamWeaver rather than with IE. If you are using Windows you should be able to change file associations, so that all web pages including JSP will be opened in your browser.

HELP about analog output video

Hello, I´m need help about analog output video in Premiere CS5 using Matrox RTX2. I need to crop a video with resolution in 1440x1080 to 4:3 in output analog. But what happens is wrong (I think). My video is in format anamorphic and the other option is 16:9 letterbox. Is there any way to crop the video without using effects. Thanks a Lot and sorry my bad english (my native language is Portuguese).

There are no 4:3 HD specifications. You'll have to put the video into a normal SD sequence, and scale it down till the top and bottom of the video meet the frame. That way the sides will be cut off.

Extra white spaces in JSP output

Hi,
          My JSPs contain a large use of JSTL and other custom Tags.
          The problem is that the output contains too many new lines and spaces.
          I found out that APACHE Tomcat has a servlet parameter (trimSpaces=true) that solved this problem.
          Does Weblogic (9.1) have something similar ?
          Does JSPC / APPC have a special options that can solve this ?
          please advise,
          Avivi.

Before diving into this, one thing I would ask you: Why does it matter if there are extra spaces? Did you determine that your primary users are using a slow connection? Before trying to optimize this, make sure that you really have a problem to solve. You might try saving off the currently generated HTML into a test page, and compare it to a similar one with all ignorable spaces removed. If you see no difference in performance, then don't bother doing this.
          Nevertheless, one strategy for reducing empty space in JSP output is to put the ends of the JSP directives and actions on the next line, with no newlines after them.
          For instance, a pair of lines like this:
          <%@page import="foo.bar" %>
          <%@page import="bar.foo" %>
          Would be instead:
          <%@page import="foo.bar"
          %><%@page import="bar.foo"
          %>

How to get context sensitive help in JSP Pages

Is it possible to display context sensitive help in JSP Pages when I press the tab key on the keyboard base on the key focus. I don�t want to use any applet or Swing components, because it�s a web page viewed on the browser
Thanks

Java code inside a JSP is interpreted on the server and the HTML produced by the server it is shown in the client browser. The JSP code can incorporate calls to the JavaHelp API if it is available to the server. Those calls can be used on the server side to map parts of the JSP to contents of a help set (HTML pages).
Given that, you can provide context sensitive help, but when it comes to view help information, you either can show HTML only (without TOC, index, etc.) or you'd need an applet.

Saving JSP output to a file

I need to be able to save what a user sees on his browser, to a local file (where the web app runs).
The content is dynamic. It is being created using a JSP.
One way to write it to a local file would be to move the content creation from a JSP to a servlet and write to the HTTP response as well as to a file in the servlet.
That's going to make it look messy.
Any thoughts on how I could make this happen while continuing to use a JSP?

OK, so now I've tried it, it's essentially what is described in the J2EE tutorial:
/* File 1 */
import java.io.*;
import javax.servlet.*;
import javax.servlet.http.*;
* passes on a subclass of HttpServletResponseWrapper
* in order to replace the output writer.
public class OutReplacementFilter implements Filter {
public void init(FilterConfig filterConfig) throws ServletException { }
public void destroy() { }
public void doFilter(ServletRequest request, ServletResponse response, FilterChain chain)
              throws IOException, ServletException {
    //wrap the original response
    HttpServletResponse newResponse = new ReplacementHttpServletResponse((HttpServletResponse) response);
    //pass it to the resource
    chain.doFilter(request, newResponse);
    //get what the resource wrote
    String output = newResponse.toString();
    //put it to the output stream
    PrintWriter out = response.getWriter();
    out.write(output);
    out.close();
    //and then put it where ever else you like
    System.out.println(output);
/* File 2 */
import java.io.*;
import javax.servlet.*;
import javax.servlet.http.*;
* returns specialized writer to capture jsp output
public class ReplacementHttpServletResponse extends HttpServletResponseWrapper {
private CharArrayWriter replacementWriter;
public ReplacementHttpServletResponse (HttpServletResponse response) {
    super(response);
    replacementWriter = new CharArrayWriter();
public PrintWriter getWriter() throws IOException {
    return new PrintWriter(replacementWriter);
public String toString() {
    return replacementWriter.toString();
}This way is easy and few keystrokes, but buffers all the output until the filter chain returns.

How to Buffer JSP Output Inside A Servlet

Hello, we are trying to Process a JSP page inside a servlet and then do more processing and finnaly add the JSP output to the response output stream. I know there is a RequestDispatcher that lets you include a JSP page. However as far as I know all you can do with the RequestDispatcher is either include the JSP (which does not buffer it but simply adds it to the output stream) or forward to the JSP page. Any ideas?

Need help w/ JSP formating a page.

Ok. I need to make the following code work. I think it needs help w/ formating is all. Below is the JSP page I would like it in as well as where I think the code should go. Not shure how to get it to display the output though.
var fullSessionName;
Function startHODSession(sessionName) {
var i = document.HODApplet.startSession(sessionName);
if (i == 0) {
fullSessionName = sessionName + document.HODApplet.getSessionID();
I need to run that part of code and display the output on a webpage. Any help would be awosme as I am lost w/ JSP more of a vb kind of guy. but learning quickly. Thanks for any help or advice.
Thanks

<input type="submit" value="Push IT" name="id"/>
</body>
</html>

Great catch on the aplet and maybe that is where I am going wrong. So let me back up a little and maybe you can get me out of my bind.
Basically what I want for a test app is: a little text box w/ a button. type in an number and click the button.
the button will then send the info to a terminal emulator. (ibm host on demand)
So that is what the 3 include statements where for. I got that from the API example.
so what I really need the page to do is print the list of connections.
so I need to get the latest session ID:
var fullSessionName;
Function startHODSession(sessionName) {
var i = document.HODApplet.startSession(sessionName);
if (i == 0) {
fullSessionName = sessionName + document.HODApplet.getSessionID();
Then run:
public int sendKeys1 (String text)
The string being what was put in the box.
for right now i do not need error checking and i know the screen will be on the right spot to accpet the input.
so if there is a better way to make it work using an applet....Im all for it.
any ideas would be great.
thanks

URGENT help with JSP

Any help with this will be really appreciated. I'm new to programming.

eg.
at the prompt for ssn, let's say I enter 111111111
I would like to see
111111111 abc xyz etc
111111111 pdg ppp etc
however, I am getting
000000000 utt tui etc
111111111 tug etg etc
How do I make limit the search to the ssn I want?
The related code is below.
Thanks.

I don't see anywhere in your code where you conditionally output a tuple from your database. You seem to be outputting everything.
Maybe you need:
<% if (sSSN==input_value){ %>
<TD><input TYPE="checkbox" name="<%=rowID %>" ></TD>
<% } %>

How to display the JSP output in the same page....

im new to JSP..... can anyone tell me how to display the output of a particular JSP page in the same page itself...... if anyone could send a small sample code it will be very useful for me....
thanks in advance

Hi Robert -
When you say you are writing a template-based Renderer, do you mean that you are creating a custom look and feel and replacing the header Renderer? If so, I'd recommend instead simply creating your own template (not template-based Renderer), and reference your template directly from your uiXML pages where you want to insert the timestamp.
You'll probably want to write a method data provider which calls System.currentTime(), convert the result to a date, and then use Java's date formatting capabilities (see java.text.format.DateFormat) to produce a user presentable String that you can return from your data provider.
For more info (and samples) on templates and data binding, see the "Templates and Data Binding" section of the "Includes and Templating in ADF UIX" help topic:

Caching JSP output

All,
          Any help or pointers to solutions would be greatly appreciated.
          We have some JSPs that produce relatively static output. Is there a way in
          WL to cache the output, instead on recreating it every time? I know that
          the Caucho JSP engine will do this (it uses browser caching directives).
          Would we need to create our own caching mechanism?
          Thanks,
          Wade Matveyenko

Can't see my Servlet/JSP outputs

{color:#0000ff}Hello there Java gurus,
I'm really excited about Java but there seems to be something i'm missing out that is slowing me down. I understand the logic behind the Servlet and JSP technologies - having context root in the webapps subdirectory of the Apache Tomcat, placing other directories like servlets, WEB-INF, classes etc in their respective places and copying .class, .xml, and .html into the proper directory of webapps subdirectories- but still I can't execute properly to view the outputs of even the simplest Servlet and JSP codes.
When I tried compiling my Servlet Java file to produce a .class file, it gave an error of "javax.servlet does not exist". What can I do again to make me execute my Servlets, because there's truely no javax.servlet in the Java subdirectory of my Program Files.
Thanks in advance for making this guy smile.

You need the jars in your classpath.

Why would a JSP output all data but fail to end the request?

Hi all,
I have a JSP which outputs some data, includes a servlet in the same application which outputs table rows, and then outputs the end of the page. I'm running iAS 6 SP4 on Solaris with iWS 6.0.
My problem is that requests complete successfully and output all data but the page continues to "load": it renders in the browser window, says Opening .... in the progress bar, but never finishes. When I stop the request and view the HTML, everything is there, right down to the last tag. So both the JSP and servlet are running to completion, but somewhere the request is not being terminated.
This is a problem because iAS will not serve any further requests to that specific application until the server is restarted. It will continue to serve pages to other applications on the same server. When shutting down the following errors are put to the log file:
[30/Jan/2002:09:52:17] info (12980): GXConn::GetNextBuffer() reports: invalid reply type received in GetNextBuffer (conn 0x3c38f48, sock 0, host 0x0, port 0)

[30/Jan/2002:09:52:17] info (12980): gxrequest.cpp:gxrequest() reports: End req /NASApp/pricing/results.jsp
I have many other JSPs which include servlets in the same application which work perfectly, and I am unable to reproduce the error on any other pages.
Any help would be appreciated.
Thanks,
Scott

Things are always clearer in the light of morning. Passing false for the inline argument to PDEContainerCreate() is the cause.
