TOmcat +Java Access Exception

[dean20007]

Hi folks

I am developing a webapp currently which (attempts to) access a remote database. In windows this works fine however when I attempt to run it locally on tomcat + Ubuntu I get the stack trace below. from what i have read this is a security and can probably be resolved my some modification Catalina.policy. but can anyone advise exactly what change has to be made

I am running Tomcat 5. Java 1.5.0 and mysql-connector-java-5.0.6-bin.jar

anyone?

You could try editing /etc/init.d/tomcat5 and change

# Use the Java security manager? (yes/no)
TOMCAT5_SECURITY=yes

then

sudo /etc/init.d/tomcat5 restart


Not sure I'd recommend leaving it like that, but it might get you started.
