At my current project, we are replacing the Postgres database with an Oracle one (finally :-)). After putting the first raw version of our Oracle DB in place, one of our existing pieces of code gave an error. It was caused by a query that was processed by Hibernate. The query was comparing the content [...]

In this post I show the steps it takes to secure an (Oracle ADF) web application by SSO as it is supplied with the Oracle Application Server.

Step 1:Install standalone OC4J

download it here
Unpack it to your PC
Set necessary environment variables

Run first time and set password (see for more installation details the oc4j Readme [...]

Since a few releases Oracle JDeveloper (finally) got the refactor option. This comes in very handy, especially when you are training a group of Oracle Forms developers in Oracle ADF. Since ADF and Java is all new to them the chances are rather big that they make a mistake in, for instance, naming classes and [...]

This time just a post that doesn’t have any technical content. This time I just want you to show the impact that a blog can have.
When I started this blog, about one year ago, I just did it as a ‘best practice’ catalog for myself. I had experienced too often a situation in which I [...]

Although I am not using any of the Oracle tools or products at my current project I am still involved with it. One of the things besides my daily job is that I am going to ‘teach’ traditional Oracle developers how to use Java and Oracle ADF in their future projects. I am convinced [...]

A few posts ago I blogged about how you can access BPEL HumanWOrkflow with a standalone Java program. In this post I will go one step further and show you how you can create a viewobject based on the HumanWorkFlowReader. You can use this viewobject for example in your JHeadstart Application Definition file so you [...]

Just for those going through the examples of Oracle BPEL that are delivered with the SOA Suite 10.1.3.1: There is a minor issue with the supplied service ‘StockQuoteService’ which is in the ‘/samples/tools’ directory and is used in some of the supplied tutorials. If you run this service, it will always return ‘0.00′, for every [...]

For a web-application I had once to create a web service proxy to communicate with a web service. In this application we also communicated with BPEL via the HumanWorkflow API. Why this is of interest you will see later.
So creating the proxy was a really simple thing to do with JDeveloper 10.1.3. Just run the [...]

In a previous post I blogged about the use of sequences for the ID column as primary key. This post goes a bit further and describes how you could have audit columns of a table fill automatically. With audit columns I mean the columns in which information is stored about who changed a row and [...]

As you may know it is a good practice to have a distinction between the owner and the user of your database objects. With this distinction you make sure that the user that is connecting to the database by the connection pool in iAS (or any other application server) is not able to drop or [...]
