Ganymede MkII

2008-09-24T09:42:00.001+10:00

Time to try Ganymede install again as the current version has got itself very confused! Install from scratch should take no more than 10-15mins (excluding any download times)

Ganymede - Latest Enterprise install eclipse-jee-ganymede-macosx-carbon.tar.gz
Sysdeo - I still use the old sysdeo plugin for basic tomcat running, used it for many years and its just easy. Installing 3.2.1 from sysdeo
Cypal - For GWT work, get the latest cypal plugin
Maven 2 - Update Manager new site, http://m2eclipse.sonatype.org/update/
Subclipse - Update Manager new site, http://subclipse.tigris.org/update_1.4.x

Some handy tips for linux based systems and java to find out and remove installed versions.

rpm -qa | grep java
rpm -qi package-1.5.0
rpm -e package-1.5.0

New Release - Shine Reference Project

2008-07-14T21:33:00.005+10:00

I have a new release of the GWT/Spring Shine Reference project out here (ver 0.3), which is an important improvement on the previous releases.

Now includes proper Data Layer : using Spring 2.5 annotations, Hibernate 3.2 and integrated HSQLDB runtime memory database.
Upgraded GWT gui to include save/delete/select functionality linking into the exposed Spring services
Maven now builds deployable war files for both the presentation (gwt) and service (spring) layers that can be dropped into a standard Tomcat install.

All of this should "just work" straight out of the box - tested on linux (fedora), mac and windows systems. Follow the "Getting Started" instructions on the project page.

Any feedback, comments, help much appreciated!

Eclipse Ganymede...

2008-07-09T11:36:00.003+10:00

This was just too painful! Unfortunately I would have to recommend to people to stay away from Ganymede if you use Subversion for version control until they sort out connectors, update sites etc. After installing on 4 machines (3 macs, 1 linux) i've finally got 3 out of 4 working - but one of them (one of the identical macs!) just wont fix and the others were such hit and miss affairs. In theory, all you need to do is add in the update site as detailed on the Polarian site

Update Sites - Direct your Eclipse update manager to both the following update sites...
* Subversive plug-in update site :
http://download.eclipse.org/technology/subversive/0.7/update-site/

* Subversive SVN Connectors update site
http://www.polarion.org/projects/subversive/download/eclipse/2.0/update-site/

I realise that its to do with license issues etc, but Eclipse really has to "just work" out of the box with Subversion soon. The update manager really needs work too. Whoever put the "Close" button where they did while hiding off the "Install" button needs to go on a design course - so fed up clicking "close" just when i've chosen "install"....!

Editing Eclipse Startup Params

2007-05-26T16:37:00.000+10:00

On Mac OS X, you start Eclipse by double clicking the Eclipse application. If you need to pass arguments to Eclipse, you'll have to edit the eclipse.ini file inside the Eclipse application bundle: select the Eclipse application bundle icon while holding down the Control Key. This will present you with a popup menu. Select "Show Package Contents" in the popup menu. Locate eclipse.ini file in the Contents/MacOS subfolder and open it with your favorite text editor to edit the command line options.

Adding Ant Paths in OSX

2007-05-26T16:14:00.000+10:00

Just like in linux, add bin path to your .bash_profile

echo 'export PATH=/Applications/java/apache-ant-1.7.0/bin:$PATH' >> ~/.bash_profile

MySQL BLOB Size

2007-05-16T13:06:00.000+10:00

I hadnt really appreciated the limitations on MySQL BLOB sizes, as i was trying to insert a jar file into a table and kept getting out of bounds exceptions... So the available options in your table are :

TINYBLOB - 2(8) - 256 bytes
BLOB - 2(16) - 65,536 - 64kb
MEDIUMBLOB - 2(24) - 16,777,216 - 16MB
LARGEBLOB - 4,294,967,296 - 4096MB
