Upgrade from version 3.2 to version 4.0

Warning: This upgrading note is a work in progress DRAFT


The version 4.0 have some significant changes if compared to version 3.x that requires some attention if you are considering a migration from such a previous version.

Removed features

Old implementation patterns to refactor

These implementation patterns that used to be possible, but already strongly discouraged, in previous versions must be now refactored:

Deprecated implementation patterns

These implementation patterns are to be considered deprecated, their usage is to be avoided (and any existing usage is to be refactored) as they will be removed in next version:

URL patterns

The version 4.0 includes a complete refactoring of the generic UI URL pattern.


If you are using traditional realm-based or JAAS authentication, make sur to update your web.xml accordingly to the one provided.

In particular make sure to have both /ui/* and /jsp/* as protected URL pattern in the <security-constraint/> bloc:


And if you are using a form-based authentication make sure your web.xml has the following login page declaration in the <login-config/> bloc:


You will also need to make sure you have the following error mappings in your web.xml:



Note: In this version, the old legacy JSP pages and the /jsp/ directory are kept for backward compatibility but they are marked as outdated deprecated. This means they will disapear in the next version.

Custom code impacts

If you are already using the HTMLTool methods (which you should), the changes are transparent.

If you have any hardcoded URL (which you should not), you must now use the HTMLTool methods instead.

URL pattern changes

The changes are described bellow (the new URL patterns are given for information and must not be hardcored but designated using the available HTMLTool methods):

  • Some of theses changes were already done in previous versions (typically 3.1 and 3.2) and the main HTMLTool methods already exists in these previous versions. You can start anticipating these changes even if you are using a previous version.
  • Any relative reference to a old JSP page located in the /jsp/ folder must now be done using an absolute reference (e.g. /jsp/SYS_work.jsp) but, better, should be refactored using the HTMLTool class methods decribed above

Upgrade procedure


The update MUST be done on an up-to-date 3.2 version.

This means that all maintenance releases patches of version 3.2 have been sucessfully applied and verified.


The following upgrade procedure is only applicable to instances managed on an instance manager (SIM), it MUST be done using command line.

  1. Connect on your instance's account: sudo su - myinstance
  2. Make a final update of your instance: sim upgrade
  3. Make a backup of your instance: sim save
  4. Make a complete backup of the instance's tomcat folder (in order to be able to revert manually to previous version if needed): cp -r tomcat tomcat-fefore.version.upgrade
  5. Change your instance's version in the manager's database: sqlite3 /var/simplicite/data/apps.db "update instances set version = '4.0' where name = 'myinstance'"
  6. Apply all database-level patches: sim ant-upgrade-configuration-db-only
  7. Stop your instance: sim stop
  8. Manually check and update if needed your instances's deployment descriptors META-INF/context.xml and WEB-INF/web.xml by comparing them to the default ones of version 4.0 (that you can find in /var/simplicite/template-4.0)
  9. Upgrade tour instance's webapp: sim ant-upgrade-war
  10. Restart your instance: sim start
  11. Remove the patch level property file rm tomcat/webapps/ROOT/WEB-INF/patches/V4.0/patches.properties
  12. Apply all configuration-level patches: sim ant-upgrade-configuration-xml-only

It is recommended to do a manual global clear cache using the generic web UI at the end of the process.
