IllegalStateException: getOutputStream() Issue???
I am fairly new to JSP and having problem with this piece of code, any insight will be appreciated. thanks
<%@ page contentType="application/vnd.ms-excel" autoFlush="false"
import="java.io.*, org.apache.poi.hssf.usermodel.HSSFWorkbook"
%>
<jsp:useBean id="FRNW" class="jsptutorial.JSPExcelUsingHSSFBean" scope="application" />
<%
try {
HSSFWorkbook wb = FRNW.createSheet() ;
ServletOutputStream os = response.getOutputStream();
wb.write(os);
os.flush();
} catch (Exception e) {
out.println("error in JSP");
%>
the code works and output what I excpected to see, but produce this error message on server. "java.lang.IllegalStateException: getOutputStream() has already been called for this response"
any idea what's going on...???
Hi
I am facing the same issue but getting it in Java code ( not JSP ) in my application, basically am using FOP to convert a XML into PDF, when i print my PDF the following error is thrown in the server :

IllegalStateException: getOutputStream() has already been called
Hi guys,
I am writing JSP to retrieve data from database and export to the user as csv or zip file. It has to be binary. I would like to a download dialog to show up and allow users to choose where to save the exported file.
Funcitonally, it works fine althrough I get an error page saying nothing to display. But it always complains that IllegalStateException: getOutputStream() has already been called for this session. I have done much research and testing, but....in vain.
Hope somebody could help me with this. so frustrated that I am about to explode.

Looked up ServletResponse, then looked for the getOutputStream() method. It says:
"Throws:
IllegalStateException - if the getWriter method has been called on this response"
You can call only one of the getWriter or getOutputStream methods, not both. You are calling both. When you use a JSP, a variable called 'out' is generated (a PrintWriter) from the the Writer you get when response.getWriter() is called. This is done before your code gets executed as one of the functions that occur when a JSP is translated to a Servlet. You then write to that out variable when you print the HTML in the JSP code.
This is best done in a Servlet, not a JSP, since there is no display and you require control over the servlet response. -
Getting java.lang.IllegalStateException error with response.getOutputStream
Hi,
I am writer a JSP site for displaying JFreeChart. The main JSP page gets some parameters then the second page out put the chart as binary data with a Java class.
I've located the part which generated the error, as follows:
Code:
OutputStream os = response.getOutputStream(); <--- this line cause the error
response.setContentType("image/png");
ChartUtilities.writeChartAsPNG(os, chart, 400, 300);
(other than it, the JSP does nothing with response or out)

Answer
Don't know if this will help--your code worked as is on my system (J2SDK 1.4.1, Tomcat 4.1.12, Linux)--but you're setting the content-type twice, and to two different values. In the page directive, you specify contentType="text/html; charset=8859_1", and then in the scriptlet, you do a response.setContentType ("application/excel");. Try changing the one in the page directive and deleting the one in the scriptlet. The servlet container may be calling getOutputStream() when it sees the text MIME type so it can prepare the out built-in variable.
Also, according to the J2EE design patterns, JSP's should only be used to produce text output. Any binary output (such as Excel files) should be produced with servlets--otherwise, the JSP becomes one big scriptlet (like this one).
If you still want to do this with a JSP, you might want to take out your try ... catch block since you're not doing anything with it. Doing so will allow you to let the servlet container handle the errors (i.e. specify error pages in the web application deployment descriptor). Either that, or at least put the close() and flush()calls in it since they can throw IOExceptions, too. :)
Finally, you should never close the servlet's output stream. Leave that up to the servlet container.

Re: Breakline problems
Aarthi Sivaram, Apr 19, 2005
In the above code sosStream = response.getOutputStream(); must be removed. Use 'out' instead of sosStream i.e. out.write(""+ibit); If you look at the Java code generated for your JSP, you can find JspWriter out = null ... .. JspWriter calls response.getOutputStream(), thats why when u call getOutputStream, u get IllegalStateException. 'out' variable is available for direct use in all JSP's, like 'request'. So that can be directly used to write.
A quick and working workaround
Leslie Leng, May 20, 2005 [replies:1]
I am not going to discuss the theory behind, as others gurus mentioned before me, are valid.
In short, getOutputStream() could not be used more than once, and also it will conflict with JSPWriter's out.
So, the quick workaround would be, at the end of the JSP page, add the following:
out.clear();
out = pageContext.pushBody();
in example:
catch(Exception e){
System.out.print(e);
out.clear();
out = pageContext.pushBody();
%>

Regards,
Dany FauziActually the stack trace indicates the the error is happening in KaptchaExample.jsp, not in a Servlet. I'm guessing that the code you've presented is in a scriptlet (i.e. inside the JSP in <% %> brackets). This is altogether the wrong place for it. JSPs are purely for generating HTML and to try and generate image responses in one is doomed to failure. Write a servlet class to generate your image file. If you want to embed a dynamically generated image in an HTML page, then you need to generate HTML which accesses the Servlet through the <img src=... tag, i.e. the browser retrieves the image data as a separate transaction.
The immediate source of the crash is that the JSP already opened the output stream in order to write HTML output, so it's too late to try and open it for the writing of image data. -

Edited by: anshu_299 on Nov 18, 2008 9:39 AMHi,
503 error comes when the client finds that the target server is not running or accessible.
Is the java system up and running? Check if the server nodes are up ?
check for the logs in work dir and if only server node is not coming up then check for default traces.

I assume the question that you forgot to ask is "how do you resolve this issue?"
[url http://download.oracle.com/javaee/1.4/api/javax/servlet/ServletResponse.html#getWriter%28%29]ServletResponse.getWriter()
[url http://download.oracle.com/javaee/1.4/api/javax/servlet/ServletResponse.html#getOutputStream%28%29]ServletResponse.getOutputStream()
Some other method has already invoked Response.getOutputStream().
You can make sure your method is invoked earlier than the other method
then the problems goes away in your method
[and the other method will get an exception when it invokes getOutputStream()]. -
We have a few Palm Pilot PQA apps on our webserver (Weblogic 4.5.1) that we
want people to be able to download.
In IE the downloads work fine. The user is presented with the "Save As"
window and so on. But in Netscape, the binary data of the PQA file just
starts streaming back to the browser.
Is this a MIME type issue? If so, how should I configure?
-MikeThanks for information.
Actually i have problem in downloading the file.
I get below exception on server side when i download file.
File is downloading without any problem in client browser.
But i get the following error on Server Console
java.lang.IllegalStateException: getOutputStream() has already been called for this response
Any suggestion /reasons for the problem. -
Hi
I'm having problems outputting a binary image from a tag handler more than once. This is apparently a known problem with JSP but I was wondering if anyone had found a workaround (other that writing a servlet).
The basic problem is that if you call ServletResponse.getOutputStream() more than once in a page or if you call it after ServletResponse.getWriter() has been called then you get:
java.lang.IllegalStateException: getOutputStream() has already been called for this response
The result is that Tag Libraries are a technology that doesn't allow you to output two binary things directly onto a page or to output any binary data if you've also output text or vice versa. That sounds extraordinarily bad to me.
I know there must be good reasons for the difficulty but surely there's a fix or a well known workaround.
Has anyone out there got over this problem or know whether any fixes are planned? Thanks.
MurrayYou can call either getOutputStream or getWriter, and you can it only once (it assumes you'll assign that to a variable and use the variable from then on). It's not a bug or problem, it's a reasonable restriction to prevent you from doing what I think you are trying to do....
So you can use the writer to write text-based output, or the output stream to write binary data.
But this is somewhat irrelevent. You can't output HTML and include binary data, like an image, in the HTML.
<div>here is some text, followed by an image</div>
<div>0a68df9834ce7932d....</div> <-- binary data...
The browser has no idea what to do with that. That's why you have image tags and object/embed tags in HTML. And the browser has to make a separate request to get the content for the image tag. So the servlet can output image data or other stuff, if the image tag is used to call a servlet to serve an image. But they are not doing with the same call the a servlet (and usually you have separate servlets for that stuff).
Ultimately, this is not a JSP/servlet issue. This is strictly and HTML, HTTP, browser issue: That's how it works and has worked since long before JSP and servlets came about. JSP/servlets do not change how HTML and browsers work in any way/shape/form. They only allow for dynamically generating content the browser gets. -
CR4Ev2 problem exporting to PDF containing Turkish characters
I know there are other threads with similar topics but I also know some people get irritated when people jump onto their threads with their own problems.
I am using CR4Ev2 and on my machine which I have installed Eclipse on I have no problems
exporting my reports to PDF, I have Turkish characters which display perfectly (they did not with
CR4Ev1 so thanks so much for that)
I have now exported my project as a WAR file and am trying to run it on another machine with the same
Tomcat and Java versions.
If I view the report via the CrystalReport Viewer the Turkish characters display with no hassel.
But if I try export the report to PDF all the Turksh characters now display as ?, (as they did in CR4Ev1)
Am I missing something, is there something that I am not including in my project that I need
when exporting the PDF.
I have installed Adobe Reader 9 on this new machine incase the Turkish langauge fonts were not in
my version 8, but still get funny ? characters, I even installed the Turksih version of Adobe 9 and still nothing. Is there some other files that I could have installed on my Eclipse machine that I have not installed
on the second machine.
I have tried both the following commands to export to PDF
CRJavaHelper.exportPDF(clientDoc, response, true);
and
CRJavaHelper.exportPDF(clientDoc, response, false);
both dont work.
I have also tried the following (which I used before with CR4Ev1)
ByteArrayInputStream byteArrayInputStream = (ByteArrayInputStream)clientDoc.getPrintOutputController().export(ReportExportFormat.PDF);
writeToFileSystem(byteArrayInputStream, EXPORT_OUTPUT); // EXPORT_OUTPUT = "c:\test.pdf"
private void writeToFileSystem(ByteArrayInputStream byteArrayInputStream, String exportFile) throws Exception {
//Use the Java I/O libraries to write the exported content to the file system.
byte byteArray[] = new byte[byteArrayInputStream.available()];
//Create a new file that will contain the exported result.
File file = new File(exportFile);
FileOutputStream fileOutputStream = new FileOutputStream(file);
ByteArrayOutputStream byteArrayOutputStream = new ByteArrayOutputStream(byteArrayInputStream.available());
int x = byteArrayInputStream.read(byteArray, 0, byteArrayInputStream.available());
byteArrayOutputStream.write(byteArray, 0, x);
byteArrayOutputStream.writeTo(fileOutputStream);
//Close streams.
byteArrayInputStream.close();
byteArrayOutputStream.close();
fileOutputStream.close();
But that also does not work.
Please can someone tell me what they think I am missing.
Oh, another note with the CRJavaHelper.exportPDF(clientDoc, response, false); command
It does work but I do get the following error in my console (both the Eclipse machine and the new one).

But as I said it seems to work fine apart from the Turkish character issue on the new machine)
Is this part of the problem or a seperate issue??
Thanks all for looking at this.
DarrenTed,
I have double checked the Java version and infact reinstalled jdk6u7 (multilanguage version) just to be
100% sure, but that did not help.
ON my Eclipse machine the Fonts are as follows
Verdana(Embedded Subset)
Type: TrueType
Encoding: Built-In
but on the other machine it is different
Verdana
Type: TrueType
Encoding: Ansi
Actual Font: Verdana
Actual Font Type: TrueType
So that does appear to be the problem, but the question is what controls this?
As I said the project is exactly the same (same WAR file) so what I have done differently or what am I
missing in the new enviroment.
I set the "Text file encoding" for the whole project to UTF-8 before I exported the project (in Eclipse)
but that didnt help. I even set the properties of each report to UTF-8.
I am sure I am missing something simple.
The only other difference is Im running XP Pro on Eclipse machine but W2KSP4 on the other, but
surely that is not the issue.
Cheers

Problem in drawing image on the fly using jsp
I have been searching the forum and web for the problem but in vain. I have wrote a jsp which creates an image on the fly from the data selected from the database. But after the image is drawn, it throws an IllegalStateException. The offending code is at the time of releasePageContext() method of the compiled jsp. I am using the following code in jsp to display the image.
BufferedImage bi = obj.getBufferedImage();
javax.imageio.ImageIO.write(bi,"png",response.getOutputStream());
I even tried to do the same with servlet, but the problem is that when I am using forward action in jsp I am getting the image but the control is in the servlet and if I am including the servlet, I am getting junk characters instead of image. I have set the content type in servlet and also in jsp.
Thank you in advance.Hi all,

It all works perfectly and returns the image. The probelm is that it causes
java.lang.IllegalStateException: getOutputStream() has already been called for this response
to be thrown in the site's logfile.
It all works perfectly by causes the log file to fill up as visitors access the image.
