[cosmos-dev] Muse Situation & Error framework...

[Mark D Weitzel <weitzelm@xxxxxxxxxx>]

Balan,

Per our conversation yesterday on the
exception framework in COSMOS, we talked about leveraging the situation
interface and object from Muse.  These are relatively simple constructs,
and there were two primary advantage to re-using them:
First, we would avoid recreating a similar
set of constructs in COSMOS.
Second, we would avoid "interface
clashes".  That is, there are scenarios where the situation will
be written to a log file or used as part of an exception.  Reusing
the Muse code would allow us to reuse the serialization logic as well and
we would not have to re-implement this code.

There are four packages that we need:
org.apache.muse.ws.dm.muws.events
org.apache.muse.ws.dm.muws.events.impl
org.apache.muse.util.messages
org.apache.muse.util.xml

Trolling through the situation object
(org.apache.muse.ws.dm.muws.events.SimpleSituation) the toXML(...) methods
depend on XmlUtils (org.apache.muse.util).  This introduces a dependency
on the jar for xerxes.  In COSMOS, we decided that we would not use
this particular jar.  I'd like to know if there is where we do not
need to include this xalan.jar as part of Muse.  This would make consumption
of these four packages easier.  Also, does it make sense for Muse
to produce a Jar of just these four packages? 

Thanks,
-mw
