I haven't tried this yet, but I would nevertheless like to say "Thank you" to all of the developers who worked on the project. Writing open source software is a great way that people can make excellent use of their innate talents and hard won skills to give something to the world as a whole. My own efforts, both as a professional programmer and as an ordinary computer user, would be significantly harder and less interesting without the many superb open source tools that I use on a regular basis. As for the issue of Struts vs. WebWork vs. something else, I suspect that even if WebWork does not acquire a large user base, if it has good ideas in it (and I'm sure it does), people will see them and those ideas will work their way into other programs as well. The intellectual efforts made by each open source programmer contribute to the community even if their own specific programs never find many users. I'm sure that, in at least some areas, WebWork will raise the bar and help make all related projects better. Thanks again. -- Alan Meyer AM Systems, Inc.

Yes it is. As to how, read a book, like mine :-) Just kidding,
even though I do recommend that anyone doing JSP development
read at least the specification. There are many things that you
just can't figure out just by looking at the APIs.
Anyway, here's a TEI that tells the container to create a variable
with the name supplied by the page author as the "id" attribute
value (you should use "id" when you create a scripting variable,
following the convention from ; "var" is a name convention
established by JSTL for variables saved only in a JSP scope):
public class MyTagTEI extends TagExtraInfo {
public VariableInfo[] getVariableInfo(TagData data) {
return new VariableInfo[] {
new VariableInfo(data.getAttributeString("id"),
"com.mycompany.SomeType",
true,
VariableInfo.AT_END)
}
}
}
The variable is of type "com.mycompany.SomeType" and made available
after the closing tag for the action element (AT_END).
If you use a JSP 1.2 container, you can replace the TEI with this
declaration in the TLD:
myTag
com.mycompany.MyTag
id
com.mycompany.SomeType
true
AT_END
This variable contains ...

The valueUnbound() method is called when the session terminates (either due to an explicit call to invalidate() or a time-out) and when the object is removed (or replaced) from the session (the removeAttribute() method is called). If you stop Tomcat gracefully, e.g. using the showdown script instead of just killing the process with Ctrl-C, it terminates all sessions so the valueUnbound() method is called. If it isn't, it's a Tomcat bug.

HI JSP
I have a HTML form, inwhich I have select list options, textarea, radio buttonset, etc. On selecting any form option(Onchange of the default options) by the user I want to populate the Querystring in the My Query information(using GETPARAMETER JSP call), displayed in the same form. I want to do that immediately their is a change in the form options(using onChange function ?) For eg. HOST : q2.paq.av.com q1.paq.av.com PORT : Data Type(dp) HTML XML ... My Query Options in the form: (populate the string with the values selected in the form) Is this possible using JSP. Kindly point me how I can do , sample code to go ahead, I will be greatful.
