Back in June, I tried the first release of Eclipse (4.2.x) aka Juno, on my MacOSX laptop. The underlying VM on my system was JDK6 at that point. Unfortunately, the results were terrible, I was not able to complete a single line of code with no lagging and freezing in the code editor. I created a question/topic on …

Όπως και πέρσι, μετά από πρόσκληση του καλού μου φίλου Τάσου Πανουσόπουλου, βρέθηκα στο τμήμα πληροφορικής των ΙΕΚ ΔΕΛΤΑ για να κάνω μια παρουσίαση εθισμού (όπως τις αποκαλώ) στον κόσμο της Java. Όπως έχω γράψει και παλιότερα για μένα τέτοιες προσκλήσεις είναι χαρά, το να μιλάς και να παρουσιάζεις κάτι το οποίο αγαπάς …

This is a note to myself post, but I hope to help others currently trying to figure out how to properly get started with an XA-Datasource definition, for Oracle 10/11g and JBoss 7.1 Application Server. I have made all the related resources link-able.

1. Make sure you have downloaded the correct JDBC drivers from …

My case: I have been using a recent version of liquibase (2.0.5). For various reasons and mostly simplicity, in terms of moving straight away from the model of keeping my own SQL statements and applying them manually,to the context of Liquibase and it's automation, I have been using the formated sql changeset/log …

I am not a huge fan of DB specific and DB oriented development. For years now I have been participating in projects using different systems like MySQL, Ingress, SQLServer and of course Oracle. The last one one (Oracle) seems to be dominating in these recent years in most of the projects I _ve seen. When it comes to …

I am doing a lot of setting up and configuration for Weblogic this week (devops I guess). I have been working with Weblogic for the past 4 years and I have to admit - like Eclipse - I have started getting used of it. I was a Netbeans / JBoss developer, and I've turned to Eclipse/ Weblogic guy. I am writing this post as …

I came across today a case where I needed to complete a unit-integration test of some quite complex enterprise Java code. Actually it was JSF backing bean with a specific inheritance chain, wired all together with some EJB's. Mockito is my library of preference for all these kinds of tests (really lovely library and …

If you ask me,what is your framework of choice when it comes to unit testing, the answer would be Mockito. I have been using it extensively in the past 1 1/2 year and tried to introduce_ it (sometimes under the hood) in some projects. I think it is simple enough to use (simpler than JMock) and to be integrated, so it …

Yesterday evening I was glad to accept an invitation by the creators and admins of the Java Code Geeks site - to participate in this initiative. It was really an honour to be invited on a site that you read every day and hosts useful and interesting material very often. it's been almost 2 years that the Java Code …

This post is just a reminder targeting new Java developers rather than experienced or senior people. Lately I have been reading and browsing on lots of different Java projects - part of my day to day duties. In order to add some fun to this activity I usually engage tools like FindBugs and PMD to check the code and …
