For me that would depend on how mission-critical those systems are and what are mitigation strategies in case of a failure. First, I prefer to install a JDK instead of a JRE, because a) it comes with trouble-shooting tools such as jstack b) several versions of JDK can be installed in parallel, and such installation does not require root privileges. Second, if I run small tools, I usually use whatever JRE is installed in the system. If I configure Tomcat in production I prefer to select an explicit JRE/JDK version by configuring it with $CATALINA_BASE/bin/setenv.sh. If the web applications that you are installing in production have not been tested on Java 7, I would stick with Java 6 for a while, but it is already the time to start testing them with Java 7. In theory, applications developed with Java 6 should run on Java 7 just fine. In practice, it needs testing, and there exist http://www.oracle.com/technetwork/java/javase/compatibility-417013.html (which is part of original Java 7.0.0 release notes) Best regards, Konstantin Kolinko --------------------------------------------------------------------- To unsubscribe, e-mail: users-unsubscr...@tomcat.apache.org For additional commands, e-mail: users-h...@tomcat.apache.org
