Re: JSP is not creating and/or populating an action form? [SOLVED]

[Peter Pilgrim <pe...@db.com>]

Oh! You have been a naught boy! Please take this white chalk write on the
"Java" blackboard

[
      I MUST MAKE SURE THAT MY JAVA BEANS REALLY DO DERIVE
     FROM THE STRUTS ACTIONFORM CLASS IF THE ACTIONSERVLET
     IS TO CREATE AND INSTANTIATE THEM!

] x 10


Here is the extract of struts-config.xml

  <form-beans>
    <form-bean      name="deptForm"                    type="com.db.moar.jsp.beans.Dept" />^
     ...
  </form-beans>

  <global-forwards>
     <forward   name="main"             path="/index.jsp" />
     <forward   name="success"          path="/hello.jsp" />
     <forward   name="failure"          path="/error.jsp" />
     ...
  </global-forwards>

  <action-mappings>
     ...
    <!-- Struts action -->
    <action    path="/TestAction"
               type="com.db.moar.jsp.actions.TestAction"
               name="deptForm"
              scope="request"
           validate="false" >
    </action>

My problem occured with the "deptForm". I could not see what the problem was?
I have associated, what was supposed to be, the form bean with the
action as you can see above. It is quite correct.

In my test "delegation.jsp"  the actual "Dept" bean is created and used.
I put in a default dummy value sin form actual to prove that is loaded.

Now when I look at the code this morning I say it did not derive ActionForm!

class Dept  extends Object {
      String firstName="foo", lastName="bar";
      getFirstName() { ... }
      ...
}

I changed the code, recompiled it:

class Dept  extends org.apache.struts.actions.ActionForm {
      String firstName="foo", lastName="bar";
      getFirstName() { ... }
      ...
}

It worked as expected. Damn!

Have you ensured that your struts-config.xml is written correctly, in particular the <action name="xxxForm"> tag parameter and the associated <form-bean name="xxxForm" type="com.a.b.c...."> tag?
