Google for "compilerSourceVM", and you should find examples of enabling 1.5.

Hi list,
Recently I upgraded Tomcat from 4.0.5 to 5.5.9, due to some unusual
problems I was experiencing with Tomcat 4.0.5. I was getting some
Java compilation errors when I used JDK1.5 features, and neither I
nor the two who replied to my message could figure out why.
Upgrading was suggested, so we upgraded to Tomcat 5.5.9.
I'm running some simple tests using some basic code that involves
JDK1.5 to find out if everything can compile correctly. However,
when I deploy my index.jsp to the server and try to launch it from
http://localhost:port#, I get a compilation error that makes no
sense to me (because I know the code I have compiles correctly with
javac). This is the index.jsp file:
<!doctype html public "-//w3c//dtd html 4.0 transitional//en"
"http://www.w3.org/TR/REC-html40/strict.dtd";>
<%@ page import="java.util.ArrayList" %>
<%@ page contentType="text/html;charset=UTF-8" language="java" %>
<html>
<head><title>TEXT</title></head>
<body>
<%
String[] s = {"1", "2"};
for (String x : s) {
}
%>
</body>
</html>
This is the error message:

I don't know what is wrong. I have JDK1.5.0_06 installed on the UNIX
box Tomcat is installed on, so the code should certainly be compiling.
One thing that bothers me is this:
When I use shutdown.sh or startup.sh to shutdown and startup Tomcat,
respectively, the terminal output tells me:
"Using JRE_HOME: /usr/local/jdk1.5.0_06"
Should this not be JAVA_HOME instead of JRE_HOME? I have a JAVA_HOME
environment variable that is set to what JRE_HOME is currently set
to. Also when I use "printenv JRE_HOME", it returns nothing. Is this
a problem?
Thanks for any help you can offer,
Dan

Hi, thanks for the reply.
I changed my code to use a JDK1.4 feature, assert, like this:
<%
boolean s = true;
assert s;
%>
and it compiled fine.
So apparently it is not compiling for JDK1.5. How would I tell it to
do so? I looked at $CATALINA_HOME/conf/server.xml, but I wasn't sure
if that was where I was supposed to make the configuration change. How
would I do so?
Thanks,
Dan
