Java EE (Java Enterprise Edition) General Discussion

I need to use the java instanceof in one of my jsp, but i'd like to use it by tab library.
I tried to use the unstandard taglib of jakarta but it gets me a strange (in my opinion) error.

I used it in the fllowing way:

...
<un:instanceOf type="Class value="${instance}">
do something
</un:instanceOf>
....

The error I got is: "According to TLD, tag un:instanceOf must be empty, but is not"

so.. I don't get how I should use it.. anyone could help me?

thanks!!
