Question in setProperty action

Hi

If we have a useBean, with say id="test", and the test bean exists in the default scope, I know that having setProperty in this action's body will not be invoked.

How does the setProperty action behave when this action (for useBean test) is put outside the useBean body? Will it reset the earlier value with the new one?

as in how would the following code work?
<jsp:useBean id="test" class="someClass"/>
<jsp:setProperty name="test" property="testProp" value="some value"/>

I hope I made my question clear.
Thanks

Yes, it will reset whether or not the bean existed or created just now because it was not found in the specified scope.

If we have a useBean, with say id="test", and the test bean exists in the default scope, I know that having setProperty in this action's body will not be invoked.


You are right. The setProperty will not the invoked only if you nest it inside the <jsp:useBean> tag. My above answer answers this question.

For ex:
If "test" bean had existed before, then the <jsp:setProperty> will not be invoked only if you code like this:



Not when you code like this:


Hope this helps,
