Is Tomcat 7 now compatible with Java 7?

Asked 15/2, 2012 at 13:32 Answered 22/5, 2014 at 7:1

If not, when is it foreseen for?

If yes, do you know if there is something special to migrate an existing installation of Tomcat 7/Java 6 to Tomcat 7/Java 7?

Thanks!

Officially Java 1.6 or later is supported.

The "later" is not true anymore, documentation has changed. See https://mcmap.net/q/471082/-is-tomcat-7-now-compatible-with-java-7 – Sampling 29/12, 2014 at 19:7

I've updated the first link. It was mistakenly pointing to the "Building Tomcat" page which is not for users but for people making changes to Tomcat itself. The page for Tomcat users says Java 6 or later. – Quean 30/12, 2014 at 16:59

Thank you for the update ;) The migration guide also confirm that. I've corrected my answer too. – Sampling 30/12, 2014 at 18:35

EDITED

As pointed out by sourcedelica the Official documentation says you can use JDK 1.6 or later so you can use Tomcat 7 with JDK 1.7.

Also check the Tomcat 7 Migration Guide .

By the way your applications developed with JDK 1.6 may fail using JDK 1.7, especially if you use classes in sun.* packages (which is bad). Even if retro-compatibility is strong, some corner cases exist, see Oracle list of incompatibilities for more details.

You can also find some stuff about this in this SO article : New features in JDK 1.6 and 1.7

looks like they updated the documentation page - it no longer says "or later" – Liggitt 21/1, 2013 at 13:29

That's true. I don't see any JDK 1.6 or later as of Feb 27, 2014 from Tomcat 7 document. – Griff 27/2, 2014 at 23:35

Last month (Feb. 2013) I updated my Java from 1.6 to 1.7. However, the update has repercussion - Tomcat 7.0.37 is not running anymore after the Java update.

I tried un-installing the Java 1.7, replace with 1.6 and the Apache Tomcat runs smoothly again. I forgot to capture the exact error message and I couldn't find also on the server logs.

FYI.

Thanks

i am using jdk6 with tomcat 7.i have following issues.

INFO: JSR 356 WebSocket (Java WebSocket 1.0) support is not available when running on Java 6.

To suppress this message, run Tomcat on Java 7, remove the WebSocket JARs from $CATALINA_HOME/lib or add the WebSocketJARs to the tomcat.util.scan.DefaultJarScanner.jarsToSkip property in $CATALINA_BASE/conf/catalina.properties.

Note that the deprecated Tomcat 7 WebSocket API will be available.
