Re: [wsrp-dev] EventDescription question

Java fully qualified class names map well to QNames, so I think there is a 
match. The schemaLocation and ModelTypes fields are two alternatives for 
providing XML schema which the QName references. One of the side issues 
this raises is the need to provide that XML schema as the party trying to 
deserialize the message won't necessarily be Java-based. Fortunately there 
are tools which will introspect Java classes and output such schema. I 
would encourage people to use the schemaLocation concept whenever possible 
as this allows standard web caching to be used.

[wsrp-dev] EventDescription question






Hello,
I have found in the second portlet specification defining events
within portlet.xml descriptor as  fully-qualified-classType, but
within WSRP v2 spec I didn't find according definition.
Instead, there are type (QName), schemaLocation (anyURI) and
schemaType (ModelTypes).


Is there a inconsistency?

Thanks and regards,
Alexey
