In an earlier post on the topic of Using JAX-RS 2.0 with WebLogic Server 12.1.3
, I described that we've utilized the shared-library model to distribute and enable it.
This approach exposes the JAX-RS 2.0 API and enlists the Jersey 2.x implementation on the target server, allowing applications to make use of it as when they are deployed through a library reference in a weblogic deployment descriptor.
The one resulting (more...)
Following from my last posting
, I thought I'd also show how Eclipse (OEPE) makes the new Java EE 7 APIs available from Oracle WebLogic Server 12.1.3.
The first step was downloading and installing the Oracle Enterprise Pack for Eclipse (OEPE) distribution from OTN.http://www.oracle.com/technetwork/developer-tools/eclipse/downloads/index.html
Firing up Eclipse, the next step is to add a new Server type for Oracle WebLogic Server 12.1.3, pointing at a local installation.
Oracle WebLogic Server 12.1.3 provides full support for Java EE 6 and also adds support for a select set of APIs from Java EE 7.
The additional APIs are:
- JSR 356 - Java API for WebSocket 1.0
- JSR 353 - Java API for JSON Processing
- JSR 339 - Java API for RESTful Web Services 2.0
- JSR 338 - Java Persistence API 2.1

I recently participated in a week long charity bike ride called Cycle4Sam,
where funds are raised to support the palliative care unit at the Women and Children's Hospital of South Australia.
The ride is conducted on a bi-annual basis in honour of young Sam Roberts, who sadly passed away from a rare genetic disease at the age of 4. His parents, Marty and Michelle and his siblings Lucy and Charlie, created the Sam Roberts Family (more...)
Java HotSpot(TM) 64-Bit Server VM warning: ignoring option MaxPermSize=256m; support was removed in 8.0
No further commentary required.
Another feature of WebLogic Server 12.1.3 that I'm sure developers will find useful is the inclusion of an implementation of JSR-353 Java API for JSON Processing.JSR 353: JavaTM API for JSON Processing
This new API, working from the foundations provided by earlier implementations such as Jackson, Jettison and Google JSon, now provides a standard API for working with JSON from Java. This goals and objectives of the API described in the initial (more...)
As part of the JAX-RS 2.0 support we are providing with WebLogic Server 12.1.3, one really useful new feature is the new Client API it provides, enabling applications to easily interact with REST services to consume and publish information.
By way of a simple example, I'll build out an application that uses the freegeoip.net
REST service to lookup the physical location of a specified IP address or domain name and deploy (more...)
We've been working on adding some Java API updates to the coming WebLogic Server 12.1.3 release.
One that I think is going to be very popular is JAX-RS 2.0
, which includes some useful new capabilities around filtering, interception and a really useful new client API.
In the WebLogic Server 12.1.3 release we are providing this in the form of an optional shared-library that contains: the JAX-RS 2.0 API, (more...)
The WLS 12c (12.1.2) release includes a new feature that enables OSGi bundles to be installed and used by deployed applications.
The full documentation is here:
In short this feature enables WLS to create an OSGi framework (Apache Felix 4.03) in which (more...)
I love the zip file distribution. It's the flavour of WLS I mostly use. Unzip, configure, go. Delete it to remove it, start all over again. Install it from a Maven goal. Easy.
Small point to note is that the zip file
distribution has been (more...)
Was talking to one of our local partners yesterday who's in the middle of an infrastructure build for FMW using a 3rd party cloud provider. He mentioned he was looking at how to handle the JTA transaction logs for their HA requirements without being able to rely on shared (more...)
The WebLogic Server documentation set has undergone a nice facelift in the 12c (12.1.2) release.
I find the breakdown sections generally quite useful to quickly locate the information I'm looking for, but I still regularly go directly to a specific book as (more...)
The WebLogic Server 12.1.2 release is now available for download from OTN.
Contains a raft of new features, check out the list in the What's New guide:
Lots of good stuff there, covering new development features as well as operational features such as dynamic (more...)
In addition to the WebSocket support we've added into the next major release of WebLogic Server (version 12.1.2 with all usual caveats with respect to release timeframes, no guarantee, etc.) we've also added support for the HTML5 ServerSent-Event model through collaborating with the GlassFish team and integrating (more...)
We've been busy working on putting in support for the WebSocket Protocol into WebLogic Server with the intent to include it in the next major release (usual caveats apply with respect to dates, times, features, etc.). Running the Autobahn WS Testsuite

In a similar vein to my last post, with this blog I'd like to try and raise the visibility of another bug that is being seen in a few different places, and for which there is already a patch available for it.
The basic issue here is that when an (more...)
Multipart File Upload with WLS 12c
Just a word for anyone out there looking to use the Servlet 3.0 file upload feature with WLS 12c.
If you use the annotation approach on the Servlet class, it works perfectly well
However if you use the web.xml file to specify (more...)
That's quite the mouthful of annotations ..
was posed recently on the WLS EJB OTN
forum asking about why WLS doesn't correctly support this combination of annotations, where the method with the @PostConstruct annotation was not being called as expected.
WebLogic Server has supported the notion of a Singleton Service for a number of releases, in which WebLogic Server will maintain a single instance of a configured singleton service on one managed server within a cluster. The singleton can be migrated to another server in the cluster, either automatically (more...)
