I'm guessing that when you run java -version from the command line, you're using the JRE. Notice that when you run Tomcat, you're running the java binary from the JDK. Check your settings for JDK_HOME and JRE_HOME. I'm guessing that you have JDK_HOME properly set (to point to the JDK), and your JRE_HOME is not set. Set your JRE_HOME to point to the installation of your JRE, and see what you get. . . . . just my two cents. /mde/ --------------------------------------------------------------------- To unsubscribe, e-mail: users-unsubscr...@tomcat.apache.org For additional commands, e-mail: users-h...@tomcat.apache.org
