WEBSPHERE 3.5.4 and STRUTS 1.0: cant remove attributes from request scope

[mi...@marine.alstom.com]

Hello,

I write an application using struts.
I have a first JSP page with a link to a second JSP page which contains a
form.
The link looks like:
<html:link href="epologin.do?cmd="Create"><bean:message key
="index.login"/></html:link>

I get the first page with the link. But, when I click on it, I get the
following message:

"...cant remove Attributes from request scope..."

I've seen a lot of mails in the struts-user list about the "doEndTag"
method; so I tried to change the code of the "FormTag" class (in
/taglib/html).
It changes nothing.

So, if anyone has a solution...

A few questions:
Where does the problem come from (Struts, Websphere)?
Is there any improvement with Websphere 4.0?

Thanks for your help.
