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

[David Whiteman <David_Whiteman@xxxxxxxxxx>]

Xerces is part of JDK 1.5.  We
prereq'd 1.5 in COSMOS, and therefore no longer needed to bundle the Xerces
jar.

We did however need to bundle Xalan,
which prompted Mark's question below.

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

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,
