> Hello dear Struts creators!
> I try to run main Struts example (Struts_Example) from a final release of 
> Struts framework.
> When I call the logon.jsp page I have next error message:
> java.lang.IllegalArgumentException: cant remove Attributes from request scope
>  at org.apache.jasper.runtime.PageContextImpl.removeAttribute
> (PageContextImpl.java:236)
>  at org.apache.struts.taglib.html.FormTag.doEndTag(FormTag.java:591)
>  at _0002flogon_0002ejsplogon_jsp_0._jspService
> (_0002flogon_0002ejsplogon_jsp_0.java:368)
>  at org.apache.jasper.runtime.HttpJspBase.service(HttpJspBase.java:126)
> ....
> It's obviously that this mistake arise when the servlet container is rendering 
> custom tags. In the logon.jsp page there is the next form tags:
> ...
> <html:form action="/logon" focus="username">
> <table border="0" width="100%">
> ....
> .... fields for input
> ....
> </html:form>
> When the container receives a tag </html:form> it runs the doEndTag() method 
> from org.apache.struts.taglib.html.FormTag object.
> Error arise in the code:
> 	// Remove the page scope attributes we created
> 	pageContext.removeAttribute(Constants.BEAN_KEY,
>                                     PageContext.REQUEST_SCOPE);
> ...
> I've walked through the code in the JBuilder's debugger. There is object with 
> key "Constants.BEAN_KEY" in the request scope. But system can't remove a 
> corresponding attribute.
> Please, explore this Struts conduct. I try to run a STANDARD Struts example. I 
> doesn't change anything in there. It worked well in beta realeases of Struts 
> (I'm using Struts from beta 2).
> With best regards.
