Oracle JDeveloper (10.1.3.2.0) extends the SOA development features from the previous release by introducing the Oracle WebCenter extension. Oracle WebCenter Suite combines the standards-based, declarative development of JavaServer Faces (JSF), the flexibility and power of portals, and a set of integrated Web 2.0 services to boost end-user productivity. Oracle WebCenter Suite provides the tools and services to embed portlets, content, customizable components, Web 2.0 content,
collaboration and communication services directly into your JavaServer Faces (JSF) application. These WebCenter features are in addition to the large set of new features that were introduced in Oracle JDeveloper 10.1.3.0 and 10.1.3.1.0. For more information on WebCenter, visit the
Oracle WebCenter Suite page on OTN.

As the saying goes you never get a second chance at a first impression. In general, that's true, but if you've been thoroughly revitalized, matured, and cosmetically re-engineered, shouldn't you get a second shot at that first impression? I'd argue that's true of Oracle's Java/J2EE Workbench, Oracle JDeveloper.
- Java Product Review — Oracle JDeveloper An IDE Worth a Second Look

I have installed it and it is really great, easy to use, helping you to create good looking widgets. As usual, like all the Apple development tools it is really intuitive. More than a long blog entry on this I am just pointing you to the DashCode page on the Apple site:

Oracle just released on OTN a new product "Oracle Data Integrator" (ODI), I wanted
to quickly take a look to the product, so I have downloaded it and
installed it on my Mac. This product is a 100% Java based solution that
you can quickly installed on mac following these steps:
1- Download and unzip ODI from OTN download page (bottom).
2- Open a terminal Window and go to the folder where you have unzipped ODI, you should have the following content:
Open the index.html and select the Getting Started Guide, this will help you to learn more about ODI using a comprehensive scenario.
3- Setup the environment variables:
> export ODI_JAVA_HOME=/Library/Java/Home/ (need to be Java 5)
> export ODI_HOME=<path to ODI installation folder>/odi/oracledi
4- Go to the $ODI_HOME/bin
> cd $ODI_HOME/bin
5- Start the HSQL databases that contain the sample application and data:
> ./startdemo.sh &
This command starts 3 different instances: repo (metadata repository), src (source db), trg (target db) that are used in the Getting Started guide. To stop the DB run the script ./stopdemo.sh .
6- You can now start the designer too using the command:
> ./designer.sh &
Select the Getting Started project and when you are in the designer switch to the Mac OS X look and feel ;-), using the Menu "Look And Feel > Standard > Mac OS X".

HTTP compression has improved a lot the download time of content from
servers. In the context of Web Service it could be very interesting to
also use HTTP compression to improve the network traffic. Firs, I am
explaining how to compress a SOAP response when you have a Web Service
running in Oracle Containers for J2EE (OC4J) using a generic servlet
filter. I have to give credit to http://www.thomas-bayer.com/
since he has created the Filter and documented how to do such thing
So you can take a look to the following article for more details, you can read the 2 following article, or jump to the next paragraph that explains how to configure your JAX-RPC based service to send compressed HTTP response.
1- Install the compression filter library in your application
Download the compression filter library 2wayfilter-1.2.jar and copy it into the Web application's WEB-INF/lib folder
2- Configure your application to use the filter
The configuration of a servlet filter is done using the web.xml where you reference which servlet or URL will be using the filter. As you may knowin JAX-RPC, the HTTP endpoint of a service are exposed as servlet and defined in the web.xml. You can choose to compress all the endpoint/URL or create a new servlet mapping, that will become a new SOAP endpoint and only compress this one. If you take the option of creating a new endpoint keep in mind that it will not be added to the WSDL automatically, so the client application will have to point explicitly to the compressed endpoint URL to take benefits of it.
<web-app xmlns="http://java.sun.com/xml/ns/j2ee" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
<description>Web Service CustomerServiceSoapHttpPort</description>
<display-name>Web Service CustomerServiceSoapHttpPort</display-name>
<!-- New servlet mapping to handle compressed SOAP Messages -->
<!-- Filter definition with mapping on the compressed endpoint -->
You can now package and deploy your application.
3- Create & Invoke the service
In this basic configuration you have only changed the servlet that is the HTTP endpoint of your service. So the compressed endpoint is not present in the WSDL, but you can use any of the URL to create your proxy.
When you have created your proxy, if you want to access the endpoint that will return the compressed response you must be sure that you are calling the correct endpoint. You can set the endpoint using the setEndpoint method, of your Web Service client.
This is it!
I will in a next post explain how you can using the Oracle Web Service client API send a compressed request that will have to be uncompressed on the server using the same filter.

Groovy release 1.0 is here now ! You can find the release at the following location: - http://dist.codehaus.org/groovy/distributions/ Congratulations to all the Groovy developers, and users that have done a great job with this language that is here in production. And it is interesting to see that more and more projects are using Groovy as part of their infrastructure to simplify development: - SOAPUI - XWiki - Spring 2 integration - Grails - ... and many development teams in custom projects So once again happy new year to all... and enjoy it with Groovy !
