Hi All,

I use Tomcat 6. I am trying to write a custom tag. When I run this tag I get java.lang.ClassNotFoundException.
I am not sure what I am doing wrong here. Any help is appreciated.
Tag Class::


TLD File::

JSP::

I have not put anthing in the web.xml since in JSP 2 we do not need the entry in web.xml

Thanks

I assume that class file is in the right place?

It'd be easier to help if you explicitly stated what class isn't being found.

When I give doTag() in the tag class, when I run the jsp I get doStartTag() method is required error.
If I change that to doStartTag() method I get java.lang.ClassNotFoundException: org.apache.jsp.test_jsp
problem finding the compiled jsp.

You know there's already date formatting stuff in JSTL, right? Weird name for a date formatting tag.

What DTD are you using in your web.xml?

Thanks for the reply.

This is just one of the parameters for the tag. Once I get this working I want to build on it with more parameters and complex logic.



Thanks

The doStartTag method is for classic handlers, not Simple tags.

Let's get back to the correct doTag() method. What happens then?

Check the TC log files for the compilation error; I don't see anything immediately obvious.

When I give doTag() method, return type void.
When I run the jsp I get a compilation error that the doStartTag() must be implemented.

Thanks

You didn't, by any chance, place a copy of jsp-api.jar in your WEB-INF/lib, did you?

The only way I can get it to compile is when I put jsp-api.jar in WEB-INF/lib.

What else should I use?

Thanks
