yes that's true
how about the delta between implementing BeanFactory vs ApplicationContext?
for Bean instantiation?

i admit this is off-topic for Struts but ontopic for Spring
and we dont have a m/l yet!

Subject: Passing runtime exp into tag

Hi all,
translating portion of old code which was using S1 and Tiles and
ran into problem.

There is one tile representing form which is being used on almost all screens.
One doesn't want to write same tile over and over again since only name
of the action differs.

Existing code used this:

// define name of the action to be a passed from parent tile
<tiles:useAttribute name="formAction" />

then it was used like this:

<html:form action="<%= formAction.toString() %>" ......


I've changed this to use S2 tags:

<s:form action="<%= formAction.toString() %>" .........

and jsp compilers complains:


JSPG0227E: Exception caught while translating /layout/formLayout.jsp:
/layout/formLayout.jsp(11,1) --> JSPG0124E: Custom tag attribute action
cannot be runtime expression. value: "[%= formAction.toString() %]"

Any ideas how to solve it?

Thanks,

Peter.

onclick="$(&#146;door3&#146;).request(); return false;"

apologies for short response

Sounds weird. Can you post your form code in the jsp?

Hi Everyone,



         
I am trying to create a java variable in the jsp scriplet and assign it a value coming from <s: property> tag

so for example

<%

      int id = <s: property value="userId"/> ;

%>



I know the above is completely incorrect, but essentially, that is what I want to accomplish. Can anyone give me any idea how this can be done? Thanks.





My action class looks like:
public class UserAction extends ActionSupport implements SessionAware, DataSourceAware, UserAware, Preparable, ModelDriven
{


private User loggedInUser;

private Map session;
private DataSource dataSource;
private int userId;




public int getUserId()
{
return userId;
}

public void setUserId(int userId)
{
this.userId = userId;
}
