Re: JSP compilation error in Tomcat 5.5 using type Vector

Of course,
Here is the very simple JSP that have written to isolate the error

<%@ page language="java" %>
<%@ page import="java.util.Vector" %>
<%@ page import="java.util.Iterator" %>
<%
Vector v = new Vector();
v.add("Hello");
v.add("World");
%>
<html>
<body>
<%
Iterator it = v.iterator();
while (it.hasNext()) {
        %>
        <%=it.next() %>
        <%
}
%>
</body>
</html>

 Can we have the code that causes this error?

Subject: JSP compilation error in Tomcat 5.5 using type Vector

Hi all,
I have a problem while trying to migrate an application from Tomcat 4.1 to Tomcat 5.5. 
I get a JasperException when tomcat try to compile a JSP :
The method add(String) is undefined for the type Vector The method iterator() is undefined for the type Vector I've put the complete trace at the end of the message.
I'm using tomcat 5.5.15. I've tried with 2 version of Java (JAVA_HOME set to 1.5.0_06 or 1.4.2_04 (with compat package)). 
I've also tried on 2 different platforms : solaris and linux.
The problem is always the same. It seems that the compiler is trying to compile the generated java file with a java 1.1 compatibility. 
I've read in the documentation that the JDT compiler should work with a
1.4 compatibility by default (I've tried to set the servlet init parameters compilerSourceVM and compilerTargetVM without success).
I've found a workaround that consist in using javac compiler instead of JDT compiler but I'd prefer using JDT compiler. 

Can someone help me and tell me what I'm doing wrong ?

Thanks in advance

Thibaut
