[OFBiz] Users - open source projects used in OFBiz

[David E. Jones]

In general this is a pretty good overview, but the biggest problem  
with this list is limiting the scope of how things are used too much.  
For example, BeanShell is used for general scripting and expression  
evaluation in various tools in OFBiz, and not just for view data  
preparation (though it is probably used primary for that). Also, Axis  
is used in both the SOAP server and client in the service engine, and  
can be used as a more general SOAP server and client independently of  
the service engine.

For the persistence tools it should be noted that there are default  
tools, but other tools can be used by either writing code or  
accessing them through JNDI. JOTM is the default transaction manager,  
but XAPool is not the default connection pool, it simply has too many  
issues and has since new people started running the project. So, we  
use (and maintain) an old version of the Minerva XA-aware connection  
pool. Hopefully someday that will change to something used more and  
something that gets more attention, but for now it seems to be  
working pretty well.

It is interesting, though difficult, to catalogue this sort of thing.  
The only real way to do it is trace dependencies in the code, and of  
course to acknowledge that these things change over time as issues  
arise...
