<bean:define> creates BOTH
- a script variable (a Java variable you can use in <% ... %> java blocs)
- a bean in specified scope (defaults to page)
So you have a "myBeanValue" variable set to 1 and a "myBeanValue" String
put into page scope.
<% myBeanValue = "2"; %> changes value of script variable. myBeanValue bean in
page scope is not impacted
<logic:equal name="myBeanValue" value="1"> checks the bean in page scope, witch equals
"1".
To solve this, you may :
- use scriptlet, not logic tag, to check script variables (NOT RECOMENDED) :
<% if ("1".equals(myBeanValue)) { %> ...<% } %>
- reuse <bean:define> to change myBeanValue, but be carreful some servlet
container don't accept multiple use of this tag with the same id, -> so NOT RECOMENDED
- not use scriptlets anymore ! Change myBeanValue by using tags, especially use
EL struts tags and JSTL :
<c:set var="myBeanValue" value="1"/>
...
<c:set var="myBeanValue" value="2"/>
...
<c:choose>
<c:when test="${myBeanValue == '1'}">...</c:when>
<c:otherwise>...</c:otherwise>
</c:choose>

Do you have the struts-bean tag library defined in your jsp:?
Something like <%@ taglib uri="/WEB-INF/struts-bean.tld" prefix="bean" %>

Hi, we have a strange Problem
with logic:equal
Look at the following code:
//--> first we create a bean
<bean:define id="myBeanValue" value="1"/>
//--> changing the value is this possible in the way???
<% myBeanValue = "2"; %>
// tests with the logic:equals tags
<logic:equal name="myBeanValue" value="1">
<br>is equal</br>
</logic:equal>
<logic:notEqual name="myBeanValue" value="1">
<br>is notequal</br>
</logic:notEqual>
After running the jsp we are getting the result= is equal!!!
But Why?? Is it not possible to redefine the variable
in the way that we try this in the example!
What makes us even more worried is that
when we debug, it neither jumps in the first nor
in the second logic:equal tag.
Please help me!
Nice Greetings
