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].

Display PDF in JSP using a content selector

Hello,
We are running on WLP 8.1 sp4. We have documents (Word and PDF) stored in the Weblogic Portal content management system. We have made several tries, but are unsuccessful in rendering a PDF inside a JSP using Content Selector tags. We can get a link to display and other properties of the content type, but we have not been able to show the actual binary property of the PDF. Has anyone climbed this mountain before, any help will be greatly appreciated!
Rob
The following displays links to the documents, but not the actual document.
<pz:contentSelector rule="novel_flu_db_archived_reports"
id="fluArchiveQuery" />
<utility:notNull item="<%=fluArchiveQuery%>">
<utility:forEachInArray array="<%=fluArchiveQuery%>" id="docA" >
<cm:getProperty id="docA" name="file" conversionType="html" />
<ad:render id="docA" />
</utility:forEachInArray>
</utility:notNull>

Thank you for the response.
Option 1 - would be great, but I am having problems getting this to work (see thread "Problem accessing a file stored in the CMS from link on JSP")
Option 2 - I need to look into, as we need to be compliant with Accessibility standards and I can't remember if IFrames pose any problems for screen readers.
Option 3 - introduces an additional step to the work flow, we would like to avoid extra work (if possible)
In looking through the archives, there was mention of a "stand alone" JSP which was not under a Portlet or the Portal. The PDF was displayed in the stand alone JSP where the mime type was altered to PDF. Would this be an option?

How to display Pdf file in iPad site

Hi
How to display Pdf file in web page which can able to view in iPad safari?
Thanks,
Arun

You can't really.
You need to use DHTML in the swf-wrapper HTML file, usually a
division wrapped iFrame, and load the PDF into the iFrame as an
overlay to the Flash.

Trouble Setting "Display PDF in browser using" by MCX

I want to force the PDF viewer in Safari to Mac OS X v10.6 built-in Preview Application instead of Adobe Acrobat Pro (9.4.0).
I found that unchecking "Display PDF in browser using:" in Acrobat's Preferences, sets the viewer in Safari to Preview. It seems unchecking this box modifies ~/Library/Preferences/com.adobe.Acrobat.Pro_x86_9.0.plist. by creating the entry root => Originals (dictionary) => BrowserIntegration (array) => item 0 as number with value 0, item 1 as boolean with value 0.
With that in mind I tried creating a MCX setting in my OD to apply root => Originals (dictionary) => BrowserIntegration (array) => item 0 as number with value 0, item 1 as boolean with value 0. Witch resulted in a grayed out, but checked settings for "Display PDF in browser using:"
I was wondering if any one has successfully figured out how to set this setting?

Hi,
Firstly during the installation of Reader X, there is an option of Customize Install. You can uncheck the Safari browser plugin from there. But this was possible before install. Now since you have installed in default mode (with above option checked during install) the method to disable plugin is as follows:
To disable the plugin-
1. Go to Library > Internet Plug-Ins
2. You will see AdobePDFViewer.plugin in the list of plugins
3. Create a new folder called Disabled Plug-Ins
4. Move the AdobePDFViewer plugin into the Disabled Plug-Ins folder
5. Restart Safari
In future if you want to re-enable this then you can put this plugin back to its original location or Reinstall Reader X (if you have permanently deleted the plug-in from your system). Reinstallation works as installing in repair mode.
AcrobatX/ReaderX uses MANAGED installation method on Mac(as compared to MANUAL installation method used in earlier versions). In case of manual installation method installation and repair was dependent on "Self heal" mechanism that required the admin privileges each time it was invoked. This raised a bit of concern so to remove this Adobe now uses Managed installation method and discontinued Self Heal mechanism.

Ignore the IDE and just execute the code. Does it work without any compilation errors or runtime exceptions? If so, then there's a problem in the IDE.

Can't uncheck 'display PDF in browser using' on mac

Reader 10.0.0
'display PDF in browser using' in the Internet preferences is stuck on to Adobe Reader. The checkbox is checked/disabled, and cannot be unchecked.
Also, viewing a PDF in the browser via FTP sticks the entire browser (hence my reason for noticing/disabling this plugin)
Had to remove the plugin file from file:///Library/Internet%20Plug-Ins/ to remove.

How to do validation in jsp using javascript

how to do validation in jsp using javascript

The same way you do with any HTML page.
Catch the onclick/onsubmit event, do your validation in javascript and then allow/cancel the action as required.
However this is javascript validation only - javascript can never call JSP code.

How to display all the surveys using content query web part

Can you please tell me how to display all the surveys using content query web part in more details? I also created a subsite and multiple surveys in that site. Then, I inserted a Content Query Web Part and select the List Type to be "Survey",
however, it returned nothing. Did I miss anything?

Hi,
OOTB Survey List does not contain any
Content Types and it has the following structure:
Response entry is represented by
List Item
Response entry consist of questions and answers, where Question correspond to
Field and Answer to Item value respectively.
For querying Survey List via CQWP the following properties could be used
BaseType
<Lists BaseType="4">
ServerTemplate
<Lists ServerTemplate="102">
Example
To retrieve all the responses from Survey lists, specify List Type property as shown on picture

Hi Vijay
Your question is not clear enough to give an answer. Do you have some difficulties with the code for opening a popup-window? There are many-many examples in the forum how to open/close a popup.
Or you do not know how to bind the popup opening with clicking a check box? Just put the code in the onSelect event handler of the check box.

How to display PDF on a page

Hi,
I have a pdf document out on intranet site that I would like to have a APex report link to that document.
This is how I defined the page:
Page type - URL
region source - http://www.xxx.xxx/../xxx.pdf
It took a long time to bring up the pdf and the document is displayed in the wrong format. Has anyone done it before? How can I display pdf in APEX?
Thanks,
Julie

Hello Julie,
Here is how I handle making my user's reference manual available from my application. It is a PDF stored like yours.
1. Define item as: Display as Text (excape special characters, does not save state)
2. Make your Label something like this: <a href="[http://www.mydomain.com/.../.../.../document.pdf] target="_blank">System User Manual</a> (substitute your link info of course)
target="_blank" opens the document in a new window.
3. Set Horizontal/Vertical Alignment appropriately (I use Left).
4. Template: Optional Label
The remaining items do not matter.
The things now that will dictate how long to download the PDF are, network speed on your end, network speed on the recipient end, network load, size of the PDF and the other normal things that cause a download to be slow.
Hope this helps,
Don
