JSP struts

Question

Hi,

How would I assign a variable within scriplet code in JSP <%> and then use struts logic tags to do stuff based on the value of the variable assigned in the scriplet code block?

I have tried using struts:logic equal and greaterthan to no avail....

Many Thanks,

Answer 1

What you are trying to do (if I understand you correct) is basically this:

<% String foo = "Test"; %>
<bean:write name="foo" />

Which, as you already know, doesn't work. That would give an error like this:

Cannot find bean foo in any scope

What I usually do, is to put my data in the page scope like this:

<% pageContext.setAttribute("foo", "Test"); %>
<bean:write name="foo" />

(This is for Struts 1.1. Newer versions may provide a better way to do it.)

Answer 2

that makes some sense thanks, i will try it out

do you know why i cant do this

<% String foo = "Test"; %>

<%logic:equal name "foo" value= "test" %>

<bean:define id="JOININGDATE" name="smlMoverDetailForm"
property="empFDJoiningDate" type="java.lang.String" toScope="session"/>

<%/Logic:equal%>

(the bean:define part gets a value from the associated form bean and works while not in the logic tags)
