 Appreciate your advice.

We have been using Tomcat 7.0.25-7.0.33 for about 9 months now on Java 7. We haven't experienced
any issues at all so far. Everything runs really smoothly.

AFAIK, the most import question is, "does the vendor application you are running support Java
7?" Tomcat 7 runs well on Java 7, but the application you want to run in Tomcat may not run
well on Java 7.

Also, keep in mind that while Tomcat 7 does run well on Java 7, by default it compiles JSPs
with a target version of Java 6. If the vendor application DOES support Java 7 and is meant
to be compiled with Java 7, you may need to change compilerSourceVM and compilerTargetVM from
the default value of "1.6" to "1.7". See
for more information.

Hope this helps,
