               out.println(imgLen.length());Your JSP was supposed to write an image to the output and you wrote some irrelevant strings to the output before? This will corrupt the image. It's like opening the image in a text editor and adding some characters before to it.
               byte [] rb = new byte[len];Memory hogging. Don't do that.
          out.println(ee);You should be throwing exceptions and at least printing its trace, not sending its toString() to the output.

HOW DO I STOP MY JSP PAGE FROM INSERTING DATA IN DATABASE EACH TIME REFRESH

Hi,
HOW DO I STOP MY JSP PAGE FROM INSERTING DATA IN DATABASE EACH TIME REFRESH?
Thanks

ThanksSTOP SHOUTING!
now, while displaying the form generate some random number, or take the current time in millis or whatever. Put that number in a hidden field. Insert that unique number along with the real data into the database, but before you do check if the number already exists. If it does you can be pretty sure this is a resubmit of the same data, so don't allow it. This is one way of many to prevent resubmission of existing data.
A good way to prevent a refresh from resubmitting altogether is to do a redirect to a result page right after you deal with the POST request. When the user presses refresh then, he/she will refresh the redirect and not the form submit.

Insert data into table from JSP page using Entity Beans(EJB 3.0)

I want to insert data into a database table from JSP page using Entity Beans(EJB 3.0).
1. I have a table 'FRIENDS', (in Oracle 10g database).
2. It has two columns, 'NAME' and 'CITY'. Both have datatype strings(varchar2).
3. Now from a JSP page, having two textfields, 'NAME' and 'CITY', I want to insert data into table 'FRIENDS'.
4. In between JSP and database is a Entity Bean(EJB 3.0) and a stateless session bean.
5. I am using JDev as editor.
Please provide me code ASAP or link with similar example.
Thank you.

Junk characters like" � � "displayed in the jsp page please help.

Hi,
I am getting junk characters like � � displayed in the jsp page.
In the JSP page i used javascript "& nbsp" for appending spaces to a string "CCR" to get "CCR " .
Now the Resultant string "CCR " has three spaces appended to its right.
This String is set in session in that JSP page.
In the next JSP page i am getting that string from session.
After getting the string the "substring" function is performed to get only the first 5 charcters of the string. Now the result is displayed as " CCR� � " with has last 2 characters as junk values � � insteed of displaying as "CCR ". Please help me in solving this issue.
Please note that initially the sting "CCR" is got from the Oracle database in Solaris Machine.
Regards,
Vijay

have you tried:
strenuously inspecting the string that is coming from the db? do an actual loop over the string, character by character, dumping to System.out to make sure the characters are EXACT coming out of the db.
note you have to append " " not just "& nbsp"
post the code that is doing the output. the relevant bean code, the jsp, everything relevant - WITH COMMENTS discussing where things are happening.
Also, is it "weird characters" in the browser only? have you done a view source on the actual html source that the browser is rendering (right click in IE and click view source). browsers can act odd if you don't feed then exactly what they want, and it looks like you're feeding it escaped characters that it is rendering as something else.

Display image on jsp page

I have to display image on jsp page with some text output. This image is already saved at a location parallel to web-inf and is generated dynamically using a servlet. I have used img tag html to display the image. Other outputs are taking their values from database.
First problem is that image will be taking time to display in comparision of other outouts from database. I have to refresh the page to get imageon my page.
Second is that if I save image in a folder parallel to web-inf in my project then it will not be displaying the image.
Can I use any jsp functionality to display image with other outputs from database. I have used "*include*". but it shows only that image and other outputs.

Best way is to use a servlet for this.
<img src="path/to/imageservlet?id=someidentifier">

<img src="path/to/imageservlet/someidentifier">In the servlet's doGet() just write code which gets an InputStream of the image (either directly generated, or just read from the local disk file system, if necessary with help of ServletContext#getRealPath(), or even from the DB by ResultSet#getBinaryStream()) and writes it to the OutputStream of the response. That's basically all. Don't forget to buffer the streams properly to speedup performance and to save memory.
You can find here a basic example: [http://balusc.blogspot.com/2007/04/imageservlet.html].

How to display PDF in JSP using Iframe

Hi All,
I am using Struts 2. I am building my file in ActionClass with seperate Method like getGeneratedPDF() in which, I am setting header of response and writing into PDF.
This method will be called from JSP by this way
s:property value="getGeneratedPDF()" />
But It displayed Junk Characters , and this PDF is not static (already Generated). It is generated and build on Fly.
I have 2 questions 1 -- How to display PDF in JSP in proper way without Junk Character in it?
questions 2 -- How to display it in Iframe?
Please help me , If you know the solution.
Thanks in Advance,
Jimmy

It is generated and build on Fly.A PDF file is a binary file, not a text file, and you're trying to display it as String. Of course you would get "junk characters". Have you ever tried opening a binary file (pdf, doc, jpg, xls, etc) using a text editor like Notepad?
I have 2 questions 1 -- How to display PDF in JSP in proper way without Junk Character in it?Display it as binary stream, not as text stream. You can display it standalone, just let the link/form/addressbar URL point to some Servlet which writes the InputStream of the PDF file to the OutputStream of the response, along with a correct set of response headers (at least content-type, content-disposition and content-length), so that the browser can open it in the correct application (which is usually Acrobat Reader). If you want to embed the PDF file in a JSP, then one of the ways is indeed using the HTML <iframe> tag.
questions 2 -- How to display it in Iframe? Just let the iframe URL point to the aforementioned Servlet.
You can find here an example of a generic file servlet, you may find it useful to get the idea how to do it: [http://balusc.blogspot.com/2007/07/fileservlet.html].

Hi,
I'd like to ask if someone know how to display region created on page X on page Y.
I've tried to create a "URL" region on Y but this doesn't work and I generally think this is blind way.
Next I've found an internal function "flows_020100.wwv_flow_disp_page_plugs()" that works pretty well (PL/SQL type region with calling the function) except that is displaying only regions on the same page. I know it's dirty hack but ...
Any ideas or hints how to solve this? Thanks ...
