Title: RE: [OS-webwork] how to access bean property?
Andre,
You'll want to do ActionContext.getContext() instead of new ActionContext().
ActionContext.getContext() gets the ThreadLocal instance which is populated by the ServletDispatcher.
You'll probably also want to maintain a reference to your TestBean :-)
Here's an example:
public class TestAction extends ActionSupport {
private TestBean myBean;
public TestBean getMyBean() {
return myBean;
}
public void setMyBean(TestBean myBean) {
this.myBean = myBean;
}
protected String doExecute() throws Exception {
myBean = new TestBean();
BeanUtil.setProperties(ActionContext.getContext().getParameters(), myBean);
return SUCCESS;
}
}
Then, in your success.jsp, which is mapped as the success result of TestAction in the views.properties or actions.xml (see the docs for how to configure actions and view mappings), you can do this:
webwork:property value=myBean !-- This will call getMyBean() on your action and put it on the top of the value stack --
The name is: webwork:property value=name/ !-- This will call getName() on your TestBean and print it to the page
/webwork:property
This is a good way to do it if you have several parameters from the TestBean that you want to display, but, if you have just one, like in this case, it's probably better to do this:
webwork:property value=myBean/name/
Which will call getMyBean.getName() and print that out to the page.
Hope that helps.

Hey all,
If Im doing something like:
In my Action.doExecute()
ActionContext ac = new ActionContext(); BeanUtil.setProperties(ac.getParameters(),new TestBean());
TestBean has one property name.
How do I access the name property using the ww taglibs?
ww:property value=name/ doesnt seem to be hitting the bean. ww:property value=$name/ does work, picking up the request parameter directly.
I thought maybe I had to name the object bean and then pass it in, like TestBean tb = new TestBean(); and then pass in the tb object and do ww:property value=tb/name/ but that doesnt work either.
I've been looking through the docs, but I cant find it. I know I'm not hitting the Bean on the view.

You'll want to do
ActionContext.getContext() instead of new ActionContext().
ActionContext.getContext()
gets the ThreadLocal instance which is populated by the ServletDispatcher.
You'll probably also want
to maintain a reference to your TestBean :-)

public class TestAction

private TestBean myBean;
public

this.myBean =
myBean;
}
protected String doExecute() throws Exception {
myBean = new
TestBean();
BeanUtil.setProperties(ActionContext.getContext().getParameters(), myBean);
return SUCCESS;
}
}
Then, in your
success.jsp, which is mapped as the success result of TestAction in the

RE: [OS-webwork] how to access bean property?
Read Jason's email again carefully. For that to work, you need to have the
ww:property value=name / tag inside the body of the first tag. Like I
said, check Jason's example again carefully.
To the developers who don't want to break up PropertyTag, here we see the
problem with a single tag that tries to do too much.

RE: [OS-webwork] how to access bean property?
I agree. PropertyTag does too much. In WW 2.0 we're planning on having
ww:property JUST do the output of the value, and have the pushing onto
the value stack be done by
ww:push
...use value here...
/ww:push
