During The Server Side Symposium in Vegas, Thomas Kurian announced that Oracle is acquiring Tangosol, during the keynote, Cameron Purdy (Tangosol’s CEO) has demonstrated how cool Coherence can be, and they have presented how it could be used in the context of XTP (Extreme Transaction Processing).
Soon more to come about this in the different technical side and blog of the Oracle’s community.
Graeme, the Grails Project Lead has published a very interesting benchmark of Grails versus Rails applications, that is available on the Grails wiki:
Grails vs Rails Performance BenchmarkingI let you read and comment on the Wiki the results… Grails development team is open to comment and improvement of the bench to capture as much information as possible.
It is also important to note that performances, productivity are very important when choosing a development environment; but something that is also key for enterprises, is the fact that Grails/Groovy “are” Java/J2EE based. This means that a Grails application is packaged, deployed, administered and monitored like any applications that already exist in the information system on J2EE application servers.
As you may remember, Oracle acquired few months back a data integration solution from Sunopsis, and has integrated it in our product under the name “Oracle Data Integrator” (ODI).
One of the first thing that I look when we got this product was the support for Scripting technologies, since it makes lot of sense to have such support in any ETL. And yes ODI has support for Jython (thought BSF). So when the dev team joined Oracle, I’ve asked the following question “did you try to use Groovy?”… I personnaly did not take the time to test, but one of the developer did and document it in his blog:
“Using Groovy and ODI” from Thierry. When I get a chance I will provide a more complete sample of using Groovy in Oracle Data Integrator.
OracleAS 10g R3 (10.1.3.x) is a certified J2EE 1.4 container, but OracleAS provides already support to some of the features of the Java Enterprise Edition 5: JavaEE 5. One of the key driver of the new EE version was simplification of the development and deployment applications. Here is the list of the JavaEE 5 features that are supported in OracleAS 10gR3 that will simplify the development of applications (in comparison to a standard J2EE 1.x development):
Support of shared library at the EAR level (<library-directory> / applib). (documentation). This comes in addition to the OracleAS 10gR3 classloader framework that allows administrators to create, and version shared libraries that can be used into applications by referencing them in the deployment plan.
Annotations Based Web Services (JSR181) that could be used for Java classes and EJB3 Session Beans (documentation)
Referencing resources using annotations in the Web container: @EJB, @Resource, @Resources, @PostConstruct, @PreDestroy, @PersistenceUnit, @PersistenceContext, @WebServiceRef, @DeclaresRoles, @RunAs (documentation)
Hope that this small summary will give you the opportunity to test some of the features of OracleAS 10g.
Oracle has announced yesterday during EclipseCon in Santa Clara (California) that it open-sources Oracle Toplink as part of the Eclipse Project.
The idea is to open source all the features of Toplink (ORM/JPA, OXM/JAXB, and EIS support), but also features that are currently under development and will be part of the Eclipse project:
Service Data Objects (SDO) implementation and SDO Data Access Service (DAS) that leverages JPA for use with SDO.* XR (XML-Relational) that provides a completely metadata driven approach to obtaining relational data as XML.
DBWS which exposes XR as a web service. With DBWS, you can easily build web services that access relational data without any programming.
One part will be kept by Oracle, this is the “glue” code that is used for the integration with OracleAS that is probably not useful for anybody but Oracle.
For details check out the press release and the FAQ.
If you are at EclipseCon do not hesitate to visit the Oracle booth to learn more about this great news for the Java developers.
It has been a long time that I did not look in the update center and development wiki of Netbeans. And I have been very pleased to see that it is possible now to register OC4J 10g as a server in Netbeans 5.5 (and 6.0). To add it in your environment just do a :
Tools > Update Center
Select “Netbeans Update Center Beta”
Select OC4J 10gYou can then configure a new Server and run/stop the server from your IDE.
This contribution allows Spring applications to leverage the OracleAS transaction manager and its features. In addition to this contribution and some previous investments of Oracle in Spring, see the Oracle and Spring page of OTN; Oracle continues to invest more and more in Spring, as contributor or as user since, as stated by Rod, Spring has an important roles in Oracle Fusion Middleware, and its upcoming Services Component Architecture offering.
When you are running OC4J in stand alone mode you are using the HTTP server that is bundle with it. This HTTP server returns by default for the HTTP information the following information: Server: Oracle Containers for J2EE
If you want to change that you just need to set the http.server.header property. For example,
java -Dhttp.server.header="My blog on Oracle" -jar oc4j.jar
will now look like:
HTTP/1.1 200 OK
Date: Mon, 26 Feb 2007 21:52:53 GMT
Server: My blog on Oracle

Packed with presentations on Grails, Groovy, Ajax & Web 2.0 and JavaEE and the core technologies that support the Grails technology, the first Grails eXchange conference (London from May 30th to June 1st) will be the place to be for any member of the Groovy/Grails community… You can already register on the conference web site: http://www.grails-exchange.com
In the previous entry I showed how you can easily take an XML feed and insert the content in the database. Let’s do the opposite now, meaning taking the data out of your database as XML. In this post I am using the Sql Dataset again but to create an XML document, using the Groovy MarkupBuilder.
As you can see, I use the builder to create XML Elements and attributes employee(first: emp.first_name , last: emp.last_name), I do reference the current record of the dataset (emp), and all this in very simple and concise code.
This will give a result like:
