Currently i am working on RCP which connects to DB using eclipse link.

But it is too slows when it is invoked from remote location.Now i would like to use Eclipse DBWS so that i can use my application as like web application

Can any one help me in migrating the application from Ecliselink to EclipseLink DBWS.

How can i use JPQL queries and Criteria queries which are there in application in DBWS.

I haven't tried anything like this, but you may be able to use a session customizer (http://wiki.eclipse.org/EclipseLink/Examples/DBWS/DBWSIntermediateCustomizer) to replace the queries generated by DBWS with your (same named, same return type) queries at runtime. As long as the names match the web service should pass the query name along to the provider, it should be able to execute your query, then return the result. If your query returns a different type than the DBWS generated one does, you'd need to manually edit the WSDL and DBWS service file (and perhaps the OR project as well).

I am facing difficulty in invoking the generated web service.

From the documentation it is not so clear how exacly we can migrate the application which using Eclipselink to use EclipseLink DBWS.

Please let me know if you know any other documentation which explains about the migration from EcipseLink to EclipseLinkDBWS.

thanks
