On Mac OS X, you have to double-click the buttons in the Toolbox to make them activate. To fix this annoyance, run the following from command line and then restart X11:
defaults write org.x.X11 wm_click_through -bool true

Maven Integration with Eclipse
Sunday, October 24th, 2010Install m2eclipse. See instructions on http://maven.apache.org/eclipse-plugin.html.
By default, Eclipse uses the JRE as the default Java environment. When you try to create a new Maven project, you will get the following message:
The Maven Integration requires that Eclipse be running in a JDK, because a number of Maven core plugins are using jars from the JDK.
Please make sure the -vm option in eclipse.ini is pointing to a JDK and verify that Installed JREs are also using JDK installs.
My JDK is installed here:
C:\Program Files\Java\jdk1.6.0_22
To resolve this, first set the JDK as the default Java environment for eclipse. It is set under Window -> Preferences -> Java -> Installed JREs. Click on the thumbnail below for a screenshot.
Next, add the following to eclipse.ini:
-vm
C:\Progra~1\Java\jdk1.6.0_22\bin\javaw.exe
Some notes on the -vm option:
- The path to the JDK must be on the line below the “-vm”.
- The path to the JDK cannot have any spaces. Enclosing the the path in quotes will not work.
- If there are spaces in the path to the JDK, then shorten using the tilde. For example “Program Files” needs to be shortened to “Progra~1″.
- The “-vm” option must be placed before the “-vmargs” option.
Below are the contents of my eclipse.ini:
-startup
plugins/org.eclipse.equinox.launcher_1.1.0.v20100507.jar
--launcher.library
plugins/org.eclipse.equinox.launcher.win32.win32.x86_1.1.0.v20100503

2. sudo vi /etc/profile.d/jdk.sh
3. Add the following two lines:
export JAVA_HOME=/usr/lib/jvm/java-6-sun
export PATH=$JAVA_HOME/bin:$PATH
4. Save and exit
5. Logout and login.
6. Install Java EE 6 SDK:
