Under the current situation where java is not part of the core, the entire JRE (or possibly a stripped down version of it) is supposed to be included in this activity.
Tested with JRE 1.6.0_03 on build 623, and sugar-jhbuild.
Currently there is a problem (http://dev.laptop.org/ticket/6026) that prevents many of the existing web start applications from running on Sugar. If you have access to the source code, you can modify your code according to the ticket and hopefully succeed.
Also, the matchbox window manager strips off the frame and display the content on fullscreen, so you are doomed if the only way to close your window is the close icon on the title bar.
Downloading the Activity
With subversion installed, do
svn co http://svn.concord.org/svn/projects/trunk/common/olpc/webstart-activity/jnlp_handler.activity
- Subversion repository: http://svn.concord.org/svn/projects/trunk/common/olpc/webstart-activity/jnlp_handler.activity
- Trac browser for the source
Installing the Bundle
Put jnlp_handler.activity under /usr/share/activities
Put jnlp_handler.activity under ~olpc/Activities Or if you have the .xo, run
in the terminal.
Be sure also to have JRE and correct activity.info.
There are two versions of activity.info under activity/. If you're working with latest source on jhbuild, use activity.info.jhbuild, that is,
cp activity.info.jhbuild activity.info
activity.info.623 is for somewhat older versions of sugar, tested on build 623:
cp activity.info.623 activity.info
The whole JRE should be copied under jre/, which is currently empty. The MANIFEST should correctly reflect the contents of the jre/ subdirectory.
For example, you can do
cd jnlp_handler.activity rmdir jre sh jre-6u3-linux-i586.bin ln -s jre1.6_03 jre
The JRE can be downloaded from http://java.sun.com/javase/downloads.
Look for Java Runtime Environment (JRE), or specifically, the file named "re-6u3-linux-i586.bin".
Creating the Bundle Package (.xo)
Have MANIFEST contain all the files to be included. In case you include the JRE tree, it'll be hard to add the entries manually. Instead you can do for example (after removing the existing jre/ entries in MANIFEST, which is based on jre-6u3-linux-i586.bin),
cd jnlp_handler.activity find jre -type f >> MANIFEST
That will create, for example, jnlp_handler-1.xo in the current directory.
