Question to include jsp pages

debolina123 Oct 23, 2009 7:18 PM

I am trying to include a jsp file and also pass a value to the jsp file.
I am using jsp:include and jsp:param for it.
The inclusion of the jsp files depends on a condition. So I have added the jsp:include inside a
h:panelGroup which is inside a a4j panel.
I have a rerender section which rerenders the a4j panel and then check for the value in the h:panel by the rendered
attribute.

<a4j:panel id="rerenderthisportion">
<h:panelGroup rendered=#{test.value}>
<jsp:include page="scripts/login.jsp">
<jsp:param name="parameterName" value="test />
</jsp:include>
</h:panelGroup>
</a4j:panel>

The code I have does not work. However, if i try a simple h:outputText it does updates the value depending on the rendered attributes.

Is there any other way to include the jsp page and pass a value to it using richfaces?

Thanks,

Deb

Hi Deb,

It (jsp include) will not work proper under JSF pages, try to use
<a4j:include viewId="scripts/login.jsp"></a4j:include>

By not working I mean, if I use the renedered attribute in the h:panelGroup the jsp pages are not getting included.
Also if I use a4j:include , how do I pass a paramter to the jsp page?

What if you use rendered="true", not "#{test.value}"?

I have tried renedered = true. It still does not include the jsp pages. Only if I do not use the rendered attribute atall, the pages gets included.

test bean should be session scoped. possible problem with conditional rendering described at:

Probably, this issue can be the cause: https://jira.jboss.org/jira/browse/RF-7947
