Nested tags : Desperately trying to get recursion to work
Hi,
I am very new to nested tags and I am trying to display a tree using
nested tags. I followed Arron's MonkeyTree example. I have been getting
'javax.servlet.ServletException: Cannot find bean in any scope' exception
(I have pasted exception trace at the end of this email) . I cannot seem to
understand why it's not able to find the bean. Following is my main jsp
files and struts-config.xml ..
I was able to run Arron's MonkeyTree example successfully.
MonkeyTreeBean class populates 'monkeyTree' (TreeNode) in it's construtor.
My Form bean does not populate the tree in construtor. Instead it populates
the tree in the action class and then forwards to the Tree.jsp.
Can somebody suggest a pointer on how to solve this problem?
Thanks in advance,
Jyothi
Tree.jsp
PS: It has a base jsp page which inserts <nested:form> ....
<template:put name="contents">
<nested:write name="deviceObjectsOMADMTreeForm" property="treeName" />
<hr>
<nested:nest property="omaDmTree" >
<jsp:include page="omadmNode.jsp" />
</nested:nest>
</template:put>
omadmNode.jsp
%@page contentType="text/html"%>
<%@ taglib uri="/WEB-INF/tld/struts-nested.tld" prefix="nested" %>
<nested:root>
<nested:write property="objName" />
</nested:root>
struts-config.xml
<form-bean name="deviceObjectsOMADMTreeForm"
type="com.openwave.opm.ui.configuration.deviceobjects.TreeForm"/>
.

Re: Nested tags : Desperately trying to get recursion to work
Posted by Max Cooper <ma...@maxcooper.com>.
I don't know anything about the nested tags, but it seems very unlikely that
this code, as a complete JSP, could work:
<%@ taglib uri="/WEB-INF/tld/struts-nested.tld" prefix="nested" %>
<nested:root>
<nested:write property="objName" />
</nested:root>
What bean is "objName" a property of? This seems to correspond with the
error message you are getting since the error message does not have a name
of the bean it was looking for.

Jyothi,
You still having problems with this?
Sorry that I haven't gotten back to you, but work's been quite busy and not
enough hours inbetween.
Just let me know.
Arron.
PS: you'll get my attention faster with this email address. :)
