jsr

There was some confusion initially due to a change in focus of one JSR and a late game submission of the other.

Eventually, the author, Doug Lea, decided to pursue making it a standard part of the Java platform as JSR-166.

The name and value can be any string except in the case of JSR 168 Struts portlets, where the parameter name must be spf_strutsAction.

Another improvement is the use of JSR-45 features to improve debugging (Note: link seems to be broken at the time of publication).

We're starting to see the release of these JSRs to public comment now, and I'll use an example from one of these in the next section.

You've now added the JSR-238 library to your development environment and are ready to start writing your internationalized MIDlet.

This API is expected to be used for tooling support as well as integration with other frameworks, libraries and JSRs.

Either way, see Resources for all the links necessary to be able to review, and possibly contribute to, JSR 326.

If it does, you can rest assured that this portlet is compliant with JSR 168.

Jigsaw is also likely to be the reference implementation for the aforementioned JSR 294, although work is still ongoing.

I decided to use JBoss 4. 0. 4, since it is one of the only Open Source implementations of JSR-181 with full JAX-RPC support.

So if this isn't the final version of the specification, why should you take a look at the early drafts of JSR 286?

Hopefully, some of these issues will be addressed in a future release of the JSR-109 specification.

The net effect of this openness remains to be seen as implementations of the JSR begin to appear on the market.

As you now know, the Apache Kato project is more than just a reference implementation of JSR 326.

Enumerations: The JSR 14 target mode of javac has no special support for enumerations.

A SIP application is a Java program that uses at least one SIP servlet written to the JSR 116 specification.

That rules out JSR 269, although there were lots of other reasons to avoid it (like fragile IDE support as of the time of prototyping).

If it is not, make sure you download and install the GA version of JBossWS since this version has full support for JSR-181 annotations.

You can tell from the low spec number of JSR-107 that the idea for the spec was thought of a decade ago.

JSR 326 is all about solving real-world problems.

In addition, JSR-109 did not provide a complete representation for the type mapping rules defined by JAX-RPC.

JSR-311 provides a set of annotations with associated classes and interfaces that can be used to expose Java objects as Web resources.

It adds support for the new JAX-RS (JSR-311) standard which allows you to build RESTful services by annotating your classes.

Now you'll create a simple JSR 168 Faces portlet application that has a single-source portlet and a single-target portlet.

Not much of the JSR 294 implementation is included, because not much exists so far.

When JSR 286 becomes the de facto portlet standard, you'll still be able to use Pluto to test for compliance.

You can use Dependency Injection (JSR-330) in action classes to inject a session object into a field of the Action class.

For a complete list of the annotations provided by the JAX-RS specification, see the JSR-311 link in the Resources section.

The perfect solution exists today and is promised by JSR 277 to be compatible with tomorrow?

Interoperability is definitely something that I would like to address before this JSR goes public review.

Core Server: By providing annotations and APIs standardized in JSR 311, you can develop a RESTful Web service in a very intuitive way.

This may be rectified in future by a Java language extension; see the sidebar entitled " Metadata and JSR 175" for more on this.

With JSR-107 nearing completion we expect that this will help JSR-347 to define itself.

The JSR 310 API allows for time zones to be versioned, and subsequently replaced, with newer versions of time zone data.

As I mentioned last month, Tiger and JSR-14 implement generic types over the Java language using "type erasure. "

There seemed to be some controversy around JSR-107 versus JSR-347 a few months back. JSR-347 is the Data Grid JSR.

The specification goes to length on this topic; it's possible to build a CVS clone with a JSR-170 backend.

If the application is a Web service, then the application must be compliant with the JSR 109 standard.

A major advantage of JSR-170 is that it is not tied to any particular underlying architecture.

Accordingly, the EJB 3. 0 Specification (JSR 220) was a radical departure from its predecessors, following this new paradigm.

It also uses standard JAX-RPC descriptors, which can be generated using JSR-181 compliant annotations.

JSR-170 supports many optional features, including access control, transactions, locking, and versioning.
