Where is the “jsp” taglib TLD?

In a special case, I need to make the same as <jsp:useBean in Java class.

It sounds like using org.apache.commons.beanutils.BeanUtils.cloneBean(Object bean) will do the work.

But what is driving me crazy is that I can’t find the TLD associated to <jsp: tags, nor the class used by <jsp:useBean.

Even <short-name>jsp</short-name> on Google gives me nothing. The JSP specs I found makes me believe that it’s not a tag like the others and that the code behind <jsp:useBean is in Java’s core.

Am I right? Have I missed something?

Answer

There’s no TLD for <jsp: elements in the JSP page. These elements are part of the JSP language. With this language you can create JSP pages but if you need to use custom TLDs like JSTL then you should use taglib directive.

What is interesting in JSP: it’s called now Jakarta Server Pages. You can read more about this in the article What is JSP? Introduction to Jakarta Server Pages.

One of the original Java web technologies, JSP is still widely used with servlets and JSTL. Here’s how to use Jakarta Server Pages to build dynamic web pages that connect to the Java back end.
