Back in the Gnome 2 days I used to love using Linux as my main developer machine but since Ubuntu and Gnome decided to build a mobile/cell phone interface for desktop PCs its gone back to the dark old days.
After Ubuntu switched to Unity I decided to jump ship (more...)
I recently worked on a project where we were using standard GWT Disclosure Panels and Tree components. When the application was sitting behind SSL we found that the arrow images were not visible in IE6. What was more frustrating was that in every other browser the images displayed correctly.
I've been playing around with RequestFactory, GWT's data centric transport/serialization mechanism and was really struggling to set up a new project that could pull data from an existing set of database tables and I wanted to share my experiences if you decide to use an existing schema.
The tutorial can (more...)

I looked at how to store images in a H2 database using groovy. The example served as nothing more than a little bit of fun. I just wondered how you'd go about doing it and wanted to explore how to get this done in groovy and (more...)
In this post I'll look at setting up a data source for JBOSS so that you can use a JNDI lookup to connect to your database from your web application. It's really easy and takes no time at all. JBOSS includes some example datasource configurations under JBOSS_HOME/docs/examples/jca that you can (more...)
I am slowly building a couple of environments and set of applications that will allow me to explore techniques, design patterns (as-well as re-learn those forgotten ones) and test drive shiny new technologies like GWT and Grails. More of a reference set for myself than anything else.
As part of (more...)
I've been playing around with some database engines based purely on Java recently (H2, HSQLDB and Apache Derby) and I've been pleasantly surprised. The one I'd like to concentrate on here is H2
It lists an impressive set of features especially compared to other databases. There is also a more (more...)
A while back I was playing with JPA/EJB3 persistence and GWT (Google Web Toolkit) but didn't want to use a heavy weight Application Server . The idea behind the application I was looking at was that it should be distributable and always run locally.
I downloaded the hibernate and JPA annotations (more...)
I had intentions of developing my blog back in 2006 and managed to write a few half decent articles. Well its now 2011 and I’ve decided to take up blogging again.
My career has shifted more towards Java and OO Development and I’m no longer working so closely with Application (more...)
While Apex is an intuitive easy to use development environment it can cause some frustrations and has a number of gotchas that are worth been aware of. The following are a few I've discovered over the last couple of months.
Validations of type PL/SQL Expression without conditions
Ending the Silence
It has been well over 3 months since my last post and I know its lame but “I just have not had the time”.
Since then I’ve been coding and documenting as my long stint at my last client came to an end last week. After a (more...)
Oracle 11g is here
Yesterday saw the launch of Oracle 11g. Eager to get my hands on a copy I popped over to OTN but was disappointed to find that its not yet available for download. However there are a stack of white papers looking at the new features. You (more...)
Clear Page Cache When Using Tabs & Sub-tabs
Update - 14th Nov 2007 : I have posted a cleaner solution to this at http://kristianjones.blogspot.com/2007/11/clear-page-cache-when-using-tabs-sub.html
Most pages you create in Apex have a number of modes that govern when processes, items and regions are displayed, executed or evaluated. (more...)
Create table as select for LOV generation
If your creating Apex applications on a regular basis then sooner or later you will have made use of LOVs. Recently I needed to create an lov using the data contained within USER_TAB_COLS as a starting point.
A feature of Oracle DDL allows (more...)
ApEx - BRANCH_TO_PAGE_ACCEPT
A colleague who also works for Oracle Consulting has recently blogged
about a very useful and not so well known feature of ApEx. BRANCH_TO_PAGE_ACCEPT is a special type of request value which basically allows you to branch to a page, passing in a page item value, skip (more...)
After recently reading a post
on Tom Kyte's blog I stumbled across an excellent resource which is quoted by another fellow reader of Tom's blog. The Oracle Co-operative FAQ
was set-up by Jonathan Lewis
and is an excellent resource for anyone who uses the Oracle Database on a (more...)
