Notice for users of Alkacon OCEE OpenCms 9.5.2 requires a new version of Alkacon OCEE. The update is free for Alkacon customers with a valid OCEE update subscription. Please contact Alkacon to receive the new version. 

Compatibility with Java versions, servlet containers and databases

OpenCms 9.5.2 has been written and tested for Java 6 and 7. We have tested with ORACLEs JDK as well as OpenJDK. OpenCms should run with all compliant JVMs. Regarding Java 8, we have problems finding Java 8 compliant versions of all used external components. We hope to offer full support for Java 8 in the next major release.

We have tested this release on the Tomcat servlet engine. OpenCms works "out of the box" with Tomcat 7, which we recommend. Others have reported deploying OpenCms successfully on other servlet containers like JBoss, BEA, Websphere, Glassfish and Resin Professional.

On the database side, we have tested with MySQL, Oracle, PostgreSQL, MS SQL Server, DB2 and HSQLDB.
