Tags nesting not working

Question

          Hi All,
          I previously posted a question about "tags nesting not working" properly.
          After making some experiments I gess I know why is was not working on Bea Weblogic
          and it was on tomcat 4.0:
          If you declare a tag as having body content of type EMPTY. For instance,
          <tag>
          <name>getvarvalue</name>
          <tagclass>nl.tue.win.riaca.ida.taglib.GetVarValueTag</tagclass>
          <teiclass>nl.tue.win.riaca.ida.taglib.GetVarValueTagTEI</teiclass>
          <bodycontent>EMPTY</bodycontent>
          <info>
          </info>
          <attribute>
          <name>id</name>
          <required>false</required>
          <rtexprvalue>true</rtexprvalue>
          </attribute>
          <attribute>
          <name>name</name>
          <required>true</required>
          <rtexprvalue>true</rtexprvalue>
          </attribute>
          </tag>
          then weblogic server doesn't call the doAfterbody() of the tag and tomcat 4.0.
          does. I was placing the code to do the pertinent thing on doAfterbody
          I don't know what the specification saids about that behaviour of the container
          but one of the to implementations should be considered as wrong?? Or maybe not?
          I hope this helps other people not to make the same mistake.
          Thanks to the people who answer to my question.
          All the best,
          Ernesto Reinaldo Barreiro.
          

Answer 1

Yes weblogic's implementation does not call the doAfterBody() if the tag does not have
          body (empty)
          The section of the spec which talks about doAfterBody says
          "public int doAfterBody()
          Process body (re)evaluation. This method is invoked by the JSP Page
          imple-mentation object after every evaluation of the body into the BodyEvaluation
          object. The method is not invoked if there is no body evaluation.
          Since for an empty tag there is no body evaluation, doAfterBody is not called.
          thanks
