Hi all,
I've been spending time with Struts 2.1.6, and the
NamedVariablePatternMatcher, and I've come across a potential issue.
The issue comes into play when defining a class such as this :
@Namespace(/content/{year}/{month})
public class ContentAction extends ActionSupport {
private
I believe this was a security fix, as there was an issue where ognl
expressions could be used to do something drastic to the application server
( like System.exit ).
I believe the expectation is that you can get around it by creating your own
customized tld or something like :
c:set
you could do this
c:set var=req value=${pageContext.request}/
s:property value=\%{ attr['req'].contextPath }/
s:property value=\%{ attr['req'].pathInfo }/
Basically, stuff the object into the pageContext somehow and then reference
it again via ognl.
It's a pain, but a very slight one.

language.

There's nothing preventing you from adding back commons-beanutils or OSCore (

You actually can do that with the default mapper, using wildcarding.
Here's an example of what we do :

param name=id{1}/param
/action

I think the answer is a 2 part solution, but you're on the right track.

2) set up your login page in your global results type. See this page for
more information :
There are a number of tools in the Eclipse space that can do this ( i.e.
they run as Eclipse plugins/features and using the underlying GEF framework
).
One that I can think of off the top of my head is StrutsIDE :

Exadel
Create a setter with the same name as your param.
ex :
for :
action name=blah class=MyAction
param name=myValueThis value/param
/action
in MyAction :
public class MyAction implements Action {
private String myValue;
public void setMyValue( String value) { this.myValue = value; }
}
If your actions occur in sequence, (
i.e. submit to an action - display action
),
it's possible to use action chaining to share objects.
