Print in JSP

Hi, I'm new to JSP and have met such a problem.
I use <%=output%> to print out the contents generated in JavaBean, whenever I refresh the page the contents will be printed out once more, while I need once only. Can you tell me what the possible problem is?
Many thanks!!

what do you mean? You mean that if you refresh, the output prints 2 times? In this case, whatever is creating the output must be appending another copy to the existing variable holding the output. If you refresh, it will call the JSP page again, so whatever the page does will run again. So if you are keeping the same bean object and not resetting the results at the start (and if you have the bean in the session scope or higher, then you are reusing the same bean), this will happen.

You can do it using javascript, see the following JSP code and follow it.
put the code in DIV tags that you do not wat to see in the final print
previewRpt() javascript method does all the work..

Printing from JSP

Hi All!
I'm using the servlet-JSP technology for displaying tables from database in browser. I'd like to know that how can I send the long, multipage tables to a printer. I have to gain such printed document, which contains all of the table with table header in all pages. I tried with JavaScript, but it's not too good.
How can I set the page properties, such as page size, orientation, ...?
Can anyone a quick solve to my problem, or other technology to generates tables?
Thanks for all,
Milcsi

JSP runs on the server, I assume you want to print on the client (browser's) machine. In this case, JSP/Servlet can't do it and you will have to investigate more into printing with javascript.
Another idea would be to make a 'printer friendly' copy of your pages that displays the info in the correct format. Then use javascript or the browser's print option to print.

Recursive Print in JSP page

I have a tree like structure in my java code and I want to print the output in my JSP page. Any idea how to perform recursive print in a JSP page.

Couldnt U just use a while loop something like the following...

<%
while(tree.next()){
%>
<tr>
<td><%=tree.getString("output") %></td>
<td><%=tree.getString("output2") %></td>
</tr>
<%
} %>
</table>
or your version of that...
Assuming U have Ur tree.next returning a false when it gets to the end.
Hope I helped.

Print previous jsp page generated content

Hi to all
Today i am trying to print a previous jsp page content in a next jsp page.
For this reason i am passing the pagecontext object from the first jsp page to second jsp.
My first jsp page coding is
===================
<%
out.print("hello");
session.setAttribute("pagedata",pageContext);
%>
Click
The coding in page.jsp is
===================
<%@ page import="java.io.*"%>
<%
PageContext p=(PageContext) session.getAttribute("pagedata");
JspWriter pageWriter = null;
HttpServletRequest respon = (HttpServletRequest)p.getRequest();
out.print(respon.getContentLength());
InputStream print=respon.getInputStream();
if(print.read()!=-1)
out.print(print.read());
%>
but page.jsp doesn't print anything
can i do this way
Please Help me.

Your code doesn't seem to be doing anything related to what you want to do. You are reading from the inputStream of the previous request and writing it to the current response. How is that supposed to work?? When you write to a response stream, the response is sent to the client and not stored in the request object or anywhere else. If you want to send the response of another page in a different page, you'll have to send all the response of the first page to a StringBuffer, send it as the response in the first request and store it in session scope. This is a way that I can think of for doing this...

FileOutputStream printOut = new
= new FileOutputStream("Samsung ML-1450 Series on
JPRASAD");If that is supposed to be the name of the printer, I am afraid that is not the way it is done. As much as I could help you, I would suggest you to take a look at the API docs and check the classes under the javax.print package.

How to print a local file from jsp

Hi,
I want to print a local file(eg. .doc,.pdf) from a jsp.
Please help me with any answer or any example code
Thanks in advance
Regards,
Sanjeev

Try this:
index1.jsp:
<%@page contentType="text/html" pageEncoding="UTF-8"%>
<html>
<head>
<meta http-equiv="Content-Type" content="text/html; charset=UTF-8">
<Link rel='alternate' media='print' href=null>
<script Language=JavaScript>
function setPrintPage(prnThis){
prnDoc = document.getElementsByTagName('Link');
prnDoc[0].setAttribute('href', prnThis);
window.print();
</script>
</head>
<body >
<a href="#" onclick="setPrintPage('index.jsp');"> Click to Print </a>
</html>This will print index.jsp without opening it in browser. Hope this helps!

Printing problem in jsp

Hi...
I have made an website by using jsp and servlets, the problem is that when click on the print option, to print that jsp page, the links get printed with that, and i want to avoid that link, please help me out from this problem,,thanks in advance...
Bye n tc

this is a html/css problem and not a java or jsp one.
create a css file print.css for example and write the following to this file :
a{
display: none;
}add this to the header of the JSPs you want to print :
<link rel="stylesheet" media="print" href="/print.css" type="text/css" />
