How to use Swing in a web Application

Can you suggest me some good PDF/tutorial or some good site for reading about using SWING in a Web Application.
In our web application we plan to use JSP/Struts for the presentation layer. However there are a few screens that require some advanced UI like color coded assets and a graphical version of Outstanding Vs Available limit. We are wondering whether we should use SWING for these screens. Do you think this is a good idea or is there a better apprach to deal with this

I'd say the biggest disadvantage is that your client machines have to download and install the bloody java plug in.
What you write about your UI ain't half vague. What the deuce is a "color coded asset"? Is it
interactive? If not, could it be represented by an image? If so, even if it is a non-static image, it is a simple
matter for your webapp to generate the image on the fly. Many web app tutorials demonstrate that.

Applet/HTML page combinations are used often when a portion of a page requires Swing/AWT capabilities, e.g. administration consoles for Weblogic and JBoss are designed this way. The page is typically divided with frames that contain either applet or HTML code.

How to use servlets in portal web application in Weblogic Portal 4.0

We are developing a Portal Web application using Weblogic Portal 4.0 where in we
have the following scenario. one JSP in webflow of a portlet calls the PipeLine
which does some processing and calls the servlet which is having the typical download
functionality. The servlet is supposed to read the data from the pipeline session
and create a CSV String that is dumped to the client browser. The problem is even
we are doing response.setContentType("application/save") in the servlet it is
still displaying the content as html in the portlet. I guess since all our request
are send to the webflow contolling servlet and it is setting the content type
and hence our servlet is not working. How do I solve this problem? Thanks Yogesh

As mentioned above, you could simply use an Applet, but I would discourage that approach.
Although it's harder to have a good UI on the web, it's definitely possible (witness Gmail). You can do all sorts of clever things like building collapsible/expandable tree structures on the web with a little Javascript/CSS.
Swing is much, much slower than regular HTML elements and the API for some Swing things is needlessly complicated (i.e. JTree).
Could you be a bit more specific about the UI elements that you need? If you wanted to do something like Photoshop, well, it would be almost impossible on the web (to do it well at least), but many other applications are very do-able.

How to provide streaming in J2EE web application?

Hi Friends,
I want to build web application which will provide streaming of data.
This data may be in raw data, binary, files, audio, video etc. As we are using HTTP protocol for web application, then how to do streaming between server and client using HTTP protocol i.e in request response manner.
If we want to send response of ~1 GB to client using servlet, then it's good idea that we should use data streaming concept. For data streaming if we use request/response architecture then servlet should send ~1 GB data in one go. Is it possible? And if we use data streaming tech. Is it our responsibility to do framing, maintaining data sequence, encoding/decoding, merge data and then store on client side?
Any help will be appreciated.
Thanks

How to use " toFront() " method in java application and in which package or class having this toFront() method.if anybody know pl. send example.

The API documentation has a link at the top of every page that says "Index". If you follow that and look for toFront(), you will find it exists in java.awt.Window and javax.swing.JInternalFrame.
To use it in a Java application, create an object x of either of those two classes and write "x.toFront();".

Any suggestions about using the data from Active directory in web-application.
Thanks.
R.Vaughn

By this time you probably have already solved this, but I think the problem is that the Search Base is relative to the attachment point specified with the PROVIDER_URL. Since you already specified "DC=mycomp,DC=isd" in that location, you merely want to set the search base to "". The error message is trying to tell you that it could only find half of the "DC=mycomp, DC=isd, DC=mycomp, DC=isd" that you specified for the search base.
Hope that helps someone.

Swing is GUI library for use in desktop applications.
JSF is a web application framework which runs on an application server and is accessed by clients via web browsers.
To fully understand what you have done, try accessing your application from a different machine than the server.
To answer your question, don't invoke System.exit() if you would like the process to continue. But that is the least of your problems.
