Hi,

I have two JSP pages, and I'm attempting to communicate between them via a javabean.

At the top of the first page, I declare my bean as so:

<jsp:useBean id=&quot;ParmHandlerBean&quot;
             scope=&quot;application&quot;
             class=&quot;mypackage.cParmHandlerBean&quot; />

If certain conditions prevail, I launch the second JSP page via a button-click as so:

  <input type=&quot;submit&quot;
         value=&quot;Transform&quot;
         onClick=&quot;window.open('response.jsp')&quot;>

In the second JSP page ("response.jsp&quot, I attempt to use the parms contained within the bean as so:

//within a scriptlet...
String sParm = ParmHandlerBean.getParm;

when the second page launches after the button-click, an error is returned mentioning that "ParmHandlerBean" is unrecognized as a variable. If, however, I try to "use" the bean in JSP page 2 ("response.jsp&quot I generate immediate errors, with the following message:
"jsp.error.useBean.duplicate"

Now, If I attempt to reference the bean in this fashion within the first JSP page (the one in which it's &quot;used&quot, things work fine. They also work fine if I &quot;<@ include&quot; jsp page number 2 in the first page, instead of launching it when the button is clicked.

Hmmmmm, I've played around with the scope parameter of the use-bean tag, but to no avail. I would assume that this can be done (sharing bean instances across JSP pages), but what am I doing wrong?

Thanks!!

If, however, I try to &quot;use&quot; the bean in JSP page 2 (&quot;response.jsp&quot I generate immediate errors, with the following message:
&quot;jsp.error.useBean.duplicate&quot;

I assume (&quot;use&quot; the bean) means that you duplicated the <jsp:useBean ...> tag exactly as you have it in the first page into the second page? If so i don't know why that wouldn't work. I do it all the time and have no problems with it.

Thanks Pete,

First, sorry about the no-header post... forgot about that (whoops!)

Anyway, I figured it out... I referenced the second jsp page in the first one, but further down as part of a directive. I had it commented out (which was &quot;working&quot;, because it wasn't being displayed), but apparently that was throwing things off because when I removed it altogether it started to work as expected. Evidently the mere mention of it (comments or otherwise) was enough to throw things off..

Thanks!
