JAXB 2.0 TCK

You can download it from https://jaxb.dev.java.net/tck.html . It's still beta, but I hope we can see a final version as JAXB 2.0 spec and RI is also finalized (very soon).

Terms in JWS 2.0 - PAWSDL vs PUWSDL and GISC vs GASC

EWS 1.2 introduces two types of WSDL:

PAckaged WSDL - PAWSDL (paw sdle): WSDL files packaged in a module.
PUblished WSDL - PUWSDL (poo sdle): WSDL files published during deployment.

While JAX-RPC uses interface (java.xml.rpc.Service) for clients, JAX-WS uses class:

GenerIc Service Class - GISC (g sc): javax.xml.ws.Service
GenerAted Service Class - GASC (gas c): generated service classes extending javax.xml.ws.Service

Let's talk about JWS with some efficiency :-)

4 cases in packaing web service endpoints in Java EE 5

Web services in Java EE 5, or JWS 2.0 changes a lot in packaging endpoints. There are 3 types in a web module:

1. Neither web.xml nor webservices.xml
In this case, full annotations are required.

2. No web.xml but webservices.xml
Annotations can be overriden by webservices.xml as defined by EWS (JSR 109) 1.2.

3. Partial web.xml and webservices.xml
"Partial" here means that web.xml doesn't have any servlet declaration for endpoints because they can be detected by @WebService Annotation unlike plain Servlets.

4. Full web.xml and webservices.xml
It's just like J2EE 1.4.

JWS ME 2.0

While I introduced the term JWS (Java Web Services) 2.0, I realized that the same notion can be applied to Java ME, i.e. JWS ME 2.0:

JWS ME 1.0

JSR 172 J2ME Web Services

JWS ME 2.0

JSR 279 Service Connection API for Java ME
JSR 280 XML API for Java ME

Eclipse 3.2M6, WTP 1.5M5, and Callisto

Eclipse 3.2M6 was out and is almost ready for the final. Eclipse 3.2 supports Java SE 5 as well as Java SE 6.

Eclipse Web Tools project also unveiled WTP 1.5M5, which is aimed at Java EE 5 with Dali, EJB 3 support and JSF. Once Eclipse 3.2 and WTP 1.5 cut the final simultaneously, you will be able to enjoy developing Java EE 5 applications on top of the full Eclipse support.

When it comes to "simultaneity", Eclipse Callisto project may interest you. As a matter of fact, getting a right set for your overall purpose, for example, Java EE development, in Eclipse was quite tricky because there have been infra and component projects with different release plans in the Eclipse ecosystem. Callisto came up to solve the difficulty and already shows some sign for "good to go."

June this year would be great for Eclipse users :-)
