Launching¶

Eclipse RCP applications are bundled up with a platform specific launcher. You can run your application as a normal Java application but this is more fun.

The osgi.parentClassloader=ext argument is used to let runtime system know that we want access to JRE extensions (specifically JAI and ImageIO).

• Return to the custom.product editor, and change to the Launching tab.

• We are going to fill in the the Program Launcher section:

  • Enter custom into the Launcher Name field
  • Under Customizing the launcher icon varies per platform select win32
  • Select the Use a single ICO file containing the 6 images: radio button
  • Press Browse... button and select icons/world.ico for the file

• Here is what this looks like when you are done:

  

• Now lets work on the Launching Arguments

  • Select the All Platforms tab, and fill the the following VM Arguments:

    -Xmx386M -Dosgi.parentClassloader=ext
    

    Hint

    If you want you can give your application more memory -Xmx756m is good for working with rasters

  • Select the macosx tab and add the following to the existing VM Arguments:

    -Djava.awt.headless=true
    

• That is it; we have enough information to move along with.
