Got a similair error exception in Aptana?

When you install Aptana 1.5 version, you’ll notice that the included Subclipse plugin is 1.4.x.

With Subversion 1.6.x. installed on your system, the Subclipse plugin in Aptana won’t work. Since Subversion client & Subclipse (& for example Tortoise SVN), all need to be from the same version.
So the solution is to upgrade Supclipse to 1.6.x.
However it bugged me, to do so.
Here is the complete solution:

1. Verify Aptana 1.4.x version: In Aptana click:
   Help > About Aptana Studio > Installation Details
   Subclipse 1.4.x. should be in this installed sofware list.
   Shutdown Aptana.
2. Go to your installation folder of Aptana, for example:
   C:\Program Files\Aptana\
3. In the features folder, remove all the folders and jars with subversion or subclipse in the file name:
   C:\Program Files\Aptana\features\
4. In the plugin folder, remove all the folders and jars with subversion or subclipse in the file name:
   C:\Program Files\Aptana\plugins\
5. From now, there is no Subclipse installed in your Aptana. Let’s install 1.6.x.
   In Aptana click: Help > Install New Software
6. Add the following software site, and name it ‘Subclipse’: http://subclipse.tigris.org/update_1.6.x
7. Select the “Core SVN Kit” and “Subclipse” checkboxes, and press “Next”
8. Incase you’ll get the following error: “The operation cannot be completed. See the details.”;
   uncheck: “Subclipse Integration for Mylyn… “
9. Incase you’ll have problems with “Accepting the agreements”, because the “Finish” button does not appear after checking “agree”. Retry the above 3 steps, but make sure, you uncheck the Mylyn on the first window (”Available software”), instead of pressing “Next” first.
10. Restart Aptana & Done! Your SVN should work right now. To verify Aptana 1.6.x version, repeat step 1.

Let’s get started with JavaFX, the java based answer from SUN to Microsoft (Silverlight) and Adobe (Flex). With JavaFX you can develop rich internet applications (RIA).

This is what you need to start coding with JavaFX Script (It’s quiet easy, I use to say; JavaFX Script looks like Javascript and CSS coding with a Java touch.)
- JavaFX 1.0 SDK

You can download it from the SUN JavaFX website: JavaFX.
From this website you can also download the NetBeans IDE 6.5, fine by me but since I’m a Eclipse / RAD user I would love to develop JavaFX from my favorite dev tool; Eclipse 3.2.

Now open your Eclipse IDE and choose:
Help > Software updates > Find and Install > Search for new features to install.
Press:New Remote Site

Name: JavaFX
URL: http://download.java.net/general/openjfx/plugins/eclipse/site.xml

Press Finish and let Eclipse search and install the plugin.
Then restart your IDE; and there you go!
