Great; these answers will help me to move forward. Shall come back incase I need additional info.
 
I shall replace the loopback classes with the 5 template java classes I see on the Cdk connector for now.
 
Thanks

I do not think showing the whole tree is necessary. Our main aim here is
to add "user" properties that are specific to the connector needed to be
added easily. Those are "config-property" section. So, if we can add
those through GUI that is enough to satisfy our need. You can leave
manual editing of "ra.xml" up to the user. We do not want hide the
resulting file either.

Yes. Note that "config-property-value" denotes a "default" value
supplied by the user. Also, "config-property" can have multiple
"description" fields. May be you can let them add multi-line description
and add each line as one "description" element inside "config-property".
Here is sample block.

<config-property>
 <description>Is Immutable</description>
 <description>True if the source never changes.</description>
 <config-property-name>Immutable</config-property-name>
 <config-property-type>java.lang.Boolean</config-property-type>
 <config-property-value>true</config-property-value>
</config-property>

Note the "config-property-type", they can be any "java.lang" objects,
may be you want to provide a "drop down" selection on that field.

Yes/no, the ra.xml schema is defined by JCA 1.5 spec. You can find it
here
http://java.sun.com/xml/ns/j2ee/connector_1_5.xsd

If we let user manually edit, Yes. Which I think we should.

The template will have a configuration class with name like
"xxManagedConnectionFactory.java". Check here for the template classes I
promised. I will keep them updated if any changes and let you know.

Properties call will only have getters and setters. By having the "config-property-value"
in the ra.xml file the container will automatically assign them on startup of connector.


Thanks.
