New Revision: 1326064
URL: http://svn.apache.org/viewvc?rev=1326064&view=rev
Log:
Adapted by hand from Lon F. Binder "CatalinaContainer Doesn't Respect
<distributable/> Node for web.xml files."
https://issues.apache.org/jira/browse/OFBIZ-4242
Per the servlet specification, the web.xml file should allow an optional
<distributable/> node to indicate that the application is clusterable.
Currently, OFBiz does not respect this setting and assumes all applications
should be distributed if any cluster configuration is provided in the
ofbiz-containers.xml file. As a result, if, for example, the DeltaManager is
enable, all applications attempt to cluster and communicate via DeltaManager.
The expected and proper functionality is to check the individual application's
web.xml file for the <distributable/> node and only use the DeltaManager if
found; otherwise the StandardManager should be used for sessions.
jleroux: replaced some tabs, reformatted, added a comment about
<distributable/> in the *-containers.file
