I am not certain this will work for you but you could set a global
variable in the script and then add a text element with script in it to
auto forward based on the global variable. Take a look at the attached
example. Look at the parameter validation script and the text element.

Drop the table that uses the dataset in the beforeFactory script. If no
report item uses the data the query should not run. Name the table in
the general properties and drop it like:
reportContext.getDesignHandle().findElement("mytable").drop();

what do you mean inner class? Any class in the cp? If so the answer is
yes. If you want to do this from script use the importPackage command.
Assume you have a class in my.package.MyObject use:
importPackage(Packages.my.package);
var tst = new MyObject();

Paula,
I am not sure I understand what you are trying to do.

Paula,
Thanks for the clarification. I am not certain Rhino (Which is the
script engine BIRT uses) supports this. As a work around you could
always use a Java event handler and do it in a java class.

I do not know of a way to to get the response object, but you can always
forward to another page using some script in text element (client side
script). You could do this conditionally based on a server side variable.
<script type="text/javascript">
function forward() {
var temp = new String(location.href);
location.replace("http://www.google.com");
return false;
}
if( <VALUE-OF>params["forward"].value</VALUE-OF> ){
forward();
}
</script>

Marc,
You can get access to the request object from the ReportContext but not
the response so I do not think there is an easy solution here. One way
may be to add a text element to the top of the report that is dropped in
the beforeFactory if the user is valid. The text element could contain
a simple script (client side) that replaces the current location with an
error page. If the user is not valid drop the other report items, if
they are valid drop the text element. To drop in the beforeFactory,
name you elements and use script similar to
reportContext.getDesignHandle().findElement("mytable").drop();
