Hi all. I have a problem with a JSP page. I am trying to use a collection
class from an entity bean, Collection findAll(). I am using a jbean between
ejb and JSP.
I keep getting this error Class java.util.Collection not found in type
declaration.(full dump below). I package jsp and jbeans in a war file then
drop it into the webapps folder under tomcat, My entity beans are in jar
file under jboss/deploy. I have a servlet that uses the ebean to output the
same Collection,Iterator classes on the screen(html) so I know these
classes exist.Why cant the JSP find the java.util.package? I have java
version 1.3.1 Hotspot vm
Please help!
THANKS!!
Here is the code:
<%@page contentType="text/html"import="java.util.*"%>
<jsp:useBean id="usersecurity" scope="session" class="UserSecurityDataBean"
/>
<html>
<head><title>JSP Page</title></head>
<body>
<%java.util.Collection sec=usersecurity.home.findAll();//this is my jbean
which references ebean home
java.util.HashSet hs=new java.util.HashSet(sec);
java.util.Iterator i=hs.iterator();
//THIS CODE WORKS IN A SERVLET!
while (i.hasNext()){%>
<h2><%=usersecurity.getWING()%>//THIS IS JUST FOR TESTING, I REALLY NEED TO
POPULATE AN OPTION BOX WITH COLLECTION
<%}%></h2>
</body>
</html>
//HERE IS THE DUMP
