OpenCms 7.0.0 Release Notes

July 4, 2007

This is the first stable release of OpenCms 7. OpenCms 7.0.0 contains many enhancements and improvements.

Features of the OpenCms 7.0.0 release

  • The internal link management has been greatly improved.
  • If files (or folders) are moved / renamed, all links to these files are now kept intact.
  • Deleting a resource that is linked by other resources does now display a warning / confirmation dialog.
  • The new "Content Relationship Engine" (CRE) allows defining arbitrary relations between OpenCms resources.
  • Native support for WebDAV access to the OpenCms VFS has been added.
  • Publishing of resources is now done using a queue, so a user can continue to work after publishing has started.
  • The concept of "Organization Units" (OUs) has been added to the internal user management.
  • System permissions are now based on a complete new set of "Roles".
  • It is now possible to delegate management of users / groups in OUs to Sub-Administrators.
  • A "switch user" (su) function for Administrators in the OpenCms Workplace is now available.
  • Many usability improvements for the OpenCms Workplace have been made, especially concerning the handling of other users locks.
  • Many dialogs in the OpenCms Workplace are more responsive because of the use of Ajax technologies.
  • The context menus in the Workplace are now cascading and can be configured individually based on the users permissions.
  • A new "Undelete" function is available on the context menu to restore deleted resources, including complete deleted subtrees.

  • Auto correction for structured XML contents now allows changes to the XML schema of existing resources.
  • A configurable search tool is now available for content managers in the Workplace.

  • Many other improvements...

Backward compatibility

We recommend everyone who uses OpenCms to update to the 7.0.0 release.

OpenCms 7.0.0 is highly backward compatible with version 6. Most templates and other OpenCms developed code from version 6 should work "out of the box" with version 7. A number of API methods from OpenCms 6 have been marked as "deprecated". In case you have made extensive use of OpenCms internal classes and APIs from version 6, there may be some changes required in your code. However, in most cases this should not take longer than a couple of hours.

Please note that since OpenCms 7 uses JSP 2.0 and Servlet 2.4 standards by default, you may have to change that back to JSP 1.2 / Servlet 2.3 so your existing OpenCms JSP templates run without change. You must edit the "web-app" node in the OpenCms web.xml file to do that.

Compatibility with Java versions, Servlet containers and Databases

OpenCms 7.0.0 has been written and tested using Java 1.5 / 1.6. It works well with Java 1.4 using the optional "Java 1.4 compatibility package". It won't work with Java 1.3. We have tested only with SUNs version of the JDK. However, OpenCms has no dependencies to sun.* packages so it should in theory run with all compliant JVMs.

We have tested this release on the Tomcat servlet engine. OpenCms 7.0.0 works "out of the box" with Tomcat 5.5, which we recommend. Others have reported deploying 7.0.0 development versions successfully on other servlet containers like JBoss, BEA and Websphere. We appreciate any feedback regarding other servlet containers.

On the database side, we have tested with MySQL 4.1, MySQL 5.x, Oracle 9.x and Oracle 10.x, as well as PostgreSQL 8.2.x and 7.4.x and MS SQL Server 2000 and 2005. The automatic update wizard for OpenCms 7.0.0 currently supports MySQL and Oracle.
