3 ways to invoke a Tag that does not have body

 

1) an empty tag: example <tax:calculate2008  user=”${username}”  />

2) a tag with nothing between opening and closing tags: example <tax:calculate2008  user=”${username}”></ tax:calculate2008>

3) a tag with only <jsp:attribute> between tags. Example

<tax:calculate2008  user=”${username}”>

            <jsp:attribute name=”user”>${username}</ jsp:attribute>

</ tax:calculate2008>

 

Remember jsp:attribute is only tag you can put in body even when body content for that tag is declared as empty.

For other things you will get a big org.apache.jasper.JasperException
