I need to do the following project in Swing: lots of Square shaped objects, and some of them are connected by lines. Need to move one or more square objects at the same time(lines connected to these objects need to move along with the objects). I also need to have the capability of adding new square object and connect it to another object with line. This project is kind of mimic some simple features of VISIO software in Java. Is it possible? How can I do it?

What I really mean is that:
I want to configure a Connection Factory, and later use it to create QueueConnection. Do I need to specify some parameter in the configuration to indicate that the Connection Factory is used to create QueueConnection(not TopicConnection), or is it necessary?

I am using WL 7.0. Is there a way to specify the Connection Factory to be used for Queue messages? Or maybe a Connection Factory can be used for both Queue and Topic?

I have saw from some web site( ex. www.china.com) small advertising images that can move around in the web page. These small images can just fly like a butterfly within the web page, and when you click on it, the advertised links will be opened. Does anybody know how to do this in DHTML and JavaScript? If possible, I would appreciate some sample code as well. Thanks in advance.
I am translating XML to HTML by using XSL. I have the following in my XSL:
<textarea name="test" width="30"></textarea>
However, I got the following HTML output:
<textarea name="test" width="30"/>
This really cause big trouble for me on the browser display. How can I make the HTML output remains the same as in XSL:
<textarea name="test" width="30"></textarea>
Can somebody help me? Thanks a lot!
My result set is a huge list. And I want to reduce the data transfered between the Oracle database and my application. If I only retrieve the first few rows from the result set, and then just close the result set. Does all the data rows from the result set already transfered from Oracle to my application regardless that I didn't read these result set? Or is it the other way around, that only the data rows that I read, has actually transfered from Oracle to my application?
And does the Oracle database server already generate the full result set in its' memory before I read a single row of result set? Thanks.
