RE: problems getting struts example to run

[Darryl Nortje <Da...@astrolabegroup.com>]

Hi Jon, I changed the two lines to what you said. I did not make any
difference still got the error
java.lang.IllegalArgumentException: cant remove Attributes from request
scope.

There is something wrong with the Constants.BEAN_KEY. it is either not being
set which I was trying to trace in the FormTag.doStartTag() at the last line
--> pageContext.setAttribute(Constants.BEAN_KEY, bean);

I can't see anything wrong with the way it is setting the attribute, so the
way it is removing the attribute should not be a problem. Any more ideas you
might have would be welcome. I'll keep going on? Thanks again for the
replies.

cheers
Darryl

Hi,

Change the two lines of code in FormTag.doEndTag that remove attributes from
the request to read:

    pageContext.getRequest().removeAttribute(Constants.BEAN_KEY);
    pageContext.getRequest().removeAttribute(Constants.FORM_KEY);

I have done my homework. I just cannot get the Struts example to run in
VAJ4.0 using WTE (not WAS). Please can someone help me. the following are
the symptoms.

I type in the url http:/localhost:8080/strutsexample/index.jsp	I then get
to the main page. When I click on the logon url, the following error msg
appears. (-*********)

now I managed to trace this down to the doEndTag() method in
org.apache.struts.taglib.FormTag class. When it executes the line
"pageContext.removeAttribute(Constants.BEAN_KEY);" IT CHUCKS THE EXCEPTION.

Thanking you in advance for your help with this. *cos i don't have a clue.

regards
Darryl
