notEmpty/empty and interation
Hi,
Using struts1.1 I have problems getting the iterate tag working.
the page scoped id bean for the element is never found. This happens when
the collection is empty or contains values.
Help is greatly appreciated.
Details:
I store a Collection under "oss_prod_list" in my session, with the following
jsp snippet:
<logic:empty name="oss_prod_list">
No products available.
</logic:empty>
<!-- @TODO: notEmpty tag does not work for some reason -->
<logic:notEmpty name="oss_prod_list">
<logic:iterate name="oss_prod_list" id="prod_list_el">
<td>
<bean:write name="prod_list_el" property="name" />
...
</logic:iterate>
</logic:notEmpty>
I get the empty as well as the not empty printed out when the collection is
empty or not. When i remove the content between the iterate tag my jsp
works, when not I get always (when collection is empty or not) the exception
that the id bean specified as iteration element is not found:
root cause
javax.servlet.ServletException: Cannot find bean prod_list_el in any scope
at
org.apache.jasper.runtime.PageContextImpl.handlePageException(PageContextImp
l.java:530)

I forgot to tell you that you should also include
the context path in the <a href=""> tag.
The <html:link> do it for you automatically.

Unfortunately this is then a absolute link to the webserver root and not
relatively to the deployed application root. This does not work, at least

You might want to give a try
<a href="/osscatalog/prodSubmit.do">
The leading slash is important.

But using the switch action is a bit strange since I do not want to switch
module but stay in the current module.
Hm however if the module is only request scoped... ???

jsp links to stay within module
Posted by ben <be...@tiscalinet.ch>.
Hi,
I link 2 jsp's in moduleA (=not default module).
In order for struts to stay within moduleA i learnt i cannot href the jsp
directly, because the module will then switch again to the default. I cannot
make the module session persistent, right?
When then using a forward action like below, I get a 404:
message Invalid path /prodSubmit was requested
source jsp:
<a href="osscatalog/prodSubmit.do">Submit a Product</a><br>
struts-config-moduleA.xml:
<action path="/osscatalog/prodSubmit"
type="org.apache.struts.actions.ForwardAction"
name="prodSubmitForm"
parameter="/osscatalog/prodSubmit.jsp"/>
Ideas?
Cheers ben

also check to see if you have logic taglib api
defined. If it is not, then check your source and you
will see the xml .. <logic:iterate right in the

seems right.
what happens if you just print "hello" in between the
tags? Does it print the correct number of times?
