++ JavaServer Pages (JSP) FAQ: http://www.jguru.com/faq/JSP

In my JSP file i am trying to use getRemoteHost() method to retrieve 
the computer name. It works in all the systems. but in one machine instead 
of displaying that computer name it is displaying the IP address of that computer. I dont know why it is displaying like that. do i need to 
change any settings in that particular machine ?

I'm specifying the error page as a page directive in a page. When there is an exception in the JSP page, the error page is called. I want to pass a parameter from the current page to the error page when there is an exception . Is this possible?

I need to do a lot of background work in my jsp and i do not want to keep my client waiting. Hence i want to redirect my client to main menu page and continue with my processing. Is it possible to implement this using multi-threading in a JSP?

I have a JSP which does some intensive I/O and consequently takes approximately 20 seconds or so to load.

How can I create a "loading...." message/HTML page which is invoked while the page is processing and then gives way to the JSP?

Does anybody could explain me the use of
<b>pageContext.include(String relativeUrlPath);</b>?
What is the difference with &lt;@ include file="..."&gt; tag?

Is it bad form to put most of your code in a try catch block?  I am using an error page to catch my exceptions but some of them are slipping through.  <br><br>I am tempted to wrap everything in the try catch so my users never see an ugly "null pointer exception" again.  <br><br>Any suggestions?

How can I prevent data to be added into my database twice when using a form on a JSP page?  On Browser refresh, the same data is added to my database table.

I have trouble displaying a string like "&lt;some data&gt;" via JSP, since they interfere with HTML tags.
For example, when displaying "&lt;user@domain.com&gt;", the &lt;user@domain.com&gt; disappears. Is there any workaround for this?
