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 support for old technical platforms (e.g. J2EE 1.4), replaced by support for new technical platforms
- Removed features and APIs marked as outdated deprecated in previous version(s), see bellow
- Changed URL patterns (with some backward compatibility however) and removed the legacy web services gateway webapp (replaced by the
/apiendpoint introduced in version 3.1), see bellow
- Removed naming flexibility for grant hooks shared script (the previously allowed
GRANTHOOKSname is now forbidden, it must now be
Old implementation patterns to refactor
These implementation patterns that used to be possible, but already strongly discouraged, in previous versions must be now refactored:
- Any usage of any hard coded URLs (see bellow) in your code or configured items (e.g. shortcuts, UI zones, actions, ...) must be avoided,
you must use the
HTMLToolmethods instead (directly in your code or using `[EXPR:(...)] in configuration items).
- Specific JSP pages are not supported anymore. You must now rewrite them as external objects
service.jsscript and were only versions 2.x's backward-compatibility synchronous wrappers of
Simplicite.Ajax, this script does not exist anymore)
- Adding custom global styles using the static
application.cssfile is not possible anymore, this is replaced by the disposition-level
- Adding custom global JS scripts using the static
application.jsfile is not possible, this is replaced by the disposition-level
- When using external authentication (e.g. OAuth2) the user data is now updated automatically, you don't need to handle the
SESSION_INFOparameter anymore (except if you have something more specific to do with it)
- The deprecated
$is now the usual alias to
$jalias is kept for compatibility but it is recomended to change it to
$instead of the
$jQuery alias you must refactor them (e.g.
$("myid")must be rewritten as
- In scripted expressions, the deprecated syntax
[<field name>]is not longer supported, you must use the syntax
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:
Simplicitenamespace is strongly discouraged
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
/jsp/* as protected URL pattern in the
And if you are using a form-based authentication make sure your
web.xml has the following login page declaration in the
You will also need to make sure you have the following error mappings in your
<error-page> <error-code>404</error-code> <location>/error?code=ERR_HTTP404&status=404</location> </error-page> <error-page> <error-code>500</error-code> <location>/error?code=ERR_HTTP500&status=500</location> </error-page>
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

- Some of theses changes were already done in previous versions (typically 3.1 and 3.2) and the main
HTMLToolmethods 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
HTMLToolclass methods decribed above
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.
- Connect on your instance's account:
sudo su - myinstance
- Make a final update of your instance:
- Make a backup of your instance:
- Make a complete backup of the instance's
tomcatfolder (in order to be able to revert manually to previous version if needed):
cp -r tomcat tomcat-fefore.version.upgrade
- 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'"
- Apply all database-level patches:
- Stop your instance:
- Manually check and update if needed your instances's deployment descriptors
WEB-INF/web.xmlby comparing them to the default ones of version 4.0 (that you can find in
- Upgrade tour instance's webapp:
- Restart your instance:
- Remove the patch level property file
- Apply all configuration-level patches:
It is recommended to do a manual global clear cache using the generic web UI at the end of the process.
