Download from jsp----

hi friends!
i am using a jsp for a download of a video file.The download step should be like,
clicking the right mouse button on the link and select,'save target as' to save the file into the computer hard disk.
Here is the place where i have been wall-blocked to proceed further.That is i have to track the user that he clicked and downloaded the specific file.The user i mean is a memeber who logs in and reaches upto the download page.
This tracking is necessary in order that the total file size downloaded for the 24 hours duration does not exceed 1.2GB.If it exceeds when the user clicks one clip he will be served with the message to relog in after 24 hours for further downloads
I am really stuck as how to implement this in the site.I am coming in the second round to the forum,seeking advise/solution to this task.Now i have to launch the site in a weeks time.
Help me please.The implementation of this tracking process is crucial to satisfy the client.
thanks and regards
sat

hi leo_pruna
If your referring to right clicking that can be done anywhere regardless of what country you are in. What you need to do is create a servlet that controls the downloads. If a user right clicks and saves target as and doesn't have rights to download the video then the servlet should forward to an html (JSP) page. At that point if they just saved target as then they should only get the HTML representation and not the video.
Thanks a lot.I really did not understand what u are telling me to do in the above paragraph.
According to my cient demand , the video download is allowed for members only.
To achieve this, i have done the implementation as follows:
After the user logs in,
When he wants to download a movie he will go to the downloadjsp, where the movie is split into many parts and each part has download link displayed .
When he clicks one of the links, he will be allowed to download through download servlet and the download servlet will ensure his limit and acts accordingly.
The above operation is performed through a left click of mouse button on the download link of download jsp.
but in japan for the video download sites, the download is allowed only by rt clicking and selecting save targer as option.This is as per the law of the country.
what i planned to do now in order that the rt click download opration to be effective is, just let the user to download from the download jsp itself, without going to the download servlet.(this effectively renders me the download without user tracking)
I did not got idea as how to incorporate the servlet way of downloading by rt clicking on the link .that is the reason i have planned to do so.
And now that u have suggested me some solution which will also enable me to track the users through the rt click action with download servlet.The above highlighted part(***) from your reply i can not follow.pl pardon me for saying that.
If u explain to me again the same , i will be able to implement.
will u take pains to explain again
thanks and regards
sat

Launching a Discoverer report from jsp page

Hi
I have a discoverer workbook created using BI Discoverer (for relational). I want to accept some parameters for this workbook from a jsp page, which will also have a "View report" button. This button when pressed should open up the Discoverer workbook and all the parameters from the jsp should be passed to the workbook.
Is it possible? If yes, any details on it?
We do the same thing successfully to launch Oracle Reports from jsps, we simply build the url in the jsp, and from jsp we submit it to a new window, and it opens up the report. Similar functionality we are looking to launch Discoverer reports.
Any help will be appreciated.
Thanks
Shalu

You can open the workbook with URL parameters with Discoverer Viewer much like you would Oracle Reports. Setting anything form the username, password, workbook name, worksheet, and parameters. All the information can be found in the following document:
http://download-east.oracle.com/docs/cd/B14099_11/bi.1012/b13918/urlstart.htm
The specific question your asking is addressed under 13.5.2 Example 2. Let me know if you have any issues

How to call RDF report from JSP page

I want to call a RDF report from JSP page. I am creating the JSP page using j developer 10G.

please help and send the reply on [email protected],[email protected]
thanks

Hi Ashok,
You can use rwservlet - nothing really to do with JDeveloper. Once you have report server up and running (hint: read http://download-uk.oracle.com/docs/cd/B14099_19/bi.1012/b14048/toc.htm), you can call a report like this:
http://server:port/rwservlet?report=my_report.rdf&destype=cache&desformat=html&p_my_parameter=xxx etcHope this helps,
John

TP4 / ADF Rich client demo just downloaded from otn / 41 compiling errors !

I just downloaded ADF Riche client demo and installed it jdev tp4.
Rebuild causes 41 compilation errors and the application is not runnable.
Is it a way to solve this ?
Some of the errors:

Forget about it ... downloading again and reinstalling it without any errors ... may be i downloaded from an older link or do some bad copy ... sorry disturbing you !

Error when trying to download from OpenLibrary

Every time I try to download a book from OpenLibrary or any other site with a similar setup I get a "Page not found' or equivalent error. It's as if a port or program is blocked by a firewall but I've made all the exceptions and even tried turning the firewall off with no luck. Previously ADE would pop up and download the PDF but now it times out immediately.

You should be able to download the 5.0.2 update for running on Vista from http://www.adobe.com/support/downloads/product.jsp?product=40&platform=Windows if you do not already have it installed.

I have Elements 5.0 with Windows Vista HE. I've added a new camera (Nikon Coolpix S630). When I try to download from this camera via USB - first my Adobe Photo Downloader does not open as it does with my other 2 digital cameras when connecting, second - when I open the downloader and choose "get photos" it lists the new "S630" but then gives me a fatal error (c0000005) when I select "Get Photos". What can I do to try to get this new camera to act like to other cameras for downloading? (Right now I have to download into Windows Gallery - save to a folder - then open Elements to get photos from folder.) Thanks for any help!

Look at the folder created by the download in to Windows gallery. What types of files are on the camera card ?
