The installer of version 1.6.10 (and 1.6.8) of TortoiseSVN has a bug that leads to an incomplete update. You must run the installer a second time and choose the second time the ‘Repair’ option for a proper upgrade. One of the symptoms of an incomplete installation is an exception when trying to compare office files [...]

This question is asked many often. However there is no one answer. Reading a lot of reactions – in one of the Linkedin community groups – I noticed that the answer is strongly related to the (test) experience of the responder. A number of the reactions endorse this question and of course other people have [...]

A little over two years ago I wrote a post on drag and drop in an adf tree component. That post was based on ADF only. In the following post I show that you can have JHeadstart generate a tree for you that supports drag and drop. Not out of the box, but with use [...]

De system directory is where JDeveloper stores the user specific settings, configurations and also (for 11g) the default domain of the embedded weblogic server. It uses the JDEV_USER_HOME environment variable to dettermine the location. If it’s not set is uses a default directory, for 11g on windows XP that’s <user dir>\Application Data\JDeveloper\systemXXX (XXX stands for [...]

Source control is off course an essential part of the development process and Subversion is an excellent system for that purpose. In the past, installation of subversion was a bit complicated because it involved several steps, an Apache webserver and not-so-accessible user management and repository configuration. However, nowadays installation and management can’t be easier, on [...]

Although JDeveloper provides loads of libraries out-of-the-box, you often need other libraries in your application. You can easily add these libraries via the project properties. This provides two options: ‘Add Library’ and ‘Add Jar / Directory’. We normally us the Add Library option because it allows to include the JavaDoc and the source code. However [...]

There are situations where you need a toolbar to provide the user with functionality like insert, update, delete, next, previous and so on. This looks straightforward, but it is not that easy to have only one toolbar to service your whole page. In this post I will show an example of how to implement such [...]

Be aware that the Call for papers for the UKOUG Tech. Conference in December is closing on Monday. ….and yes I know, having Oracle Open World almost opening its doors or The Michigan OakTable Symposium just coming up in the agenda, thinking about stuff in December is a bit strange, but…do you want to miss out [...]

I get a lot of questions on how to select all rows in a table. In this post I describe how you can do that. A common use case for this is when you want to apply changes on a set of records, for instance change the status of all records in a table. You [...]

Something new? Eh? Should you do this? Eh? In all, probably not, but for me this was a good exercise towards some more updated demo scripting for my “Boost your environment with XMLDB” presentation or hopefully more clearer relabeled Oracle Open World name for the almost same presentation called “Interfacing with Your Database via Oracle XML [...]

On the JDeveloper ADF forum there are many questions on how to change the look and feel of components. In this post I’ll explain three ways to do that. Setting skin Selector property For this we need to define a custom skin. <?xml version="1.0" encoding="ISO-8859-1"?> <skins xmlns="http://myfaces.apache.org/trinidad/skin"> <skin> <id>mySkin.desktop</id> <family>MySkin</family> [...]

‘Oracle Team Productivity Center (TPC) is an Application Lifecycle Management (ALM) tool that enables software development teams to collaborate and work productively together when developing applications using JDeveloper.’ (OTN TPC page) TPC provides unified access to different ALM repositories from within JDeveloper and it allows to define relations between the so-called work-items in these (separate) repositories.
