RMC 7.5.0.1 on Ubuntu 10.04 Lucid - fix the embedded browser

The past days endeavor for sure worth this post. Rational Method Composer was the "must have" software to run on my current dual-boot configuration.

I could not open any element, the backward Eclipse keep throwing errors like:

org.eclipse.swt.SWTError: No more handles (java.lang.UnsatisfiedLinkError: no swt-mozilla-gtk-3349 or swt-mozilla-gtk in swt.library.path, java.library.path or the jar file)
at org.eclipse.swt.SWT.error(SWT.java:3589)
......

I've obviously searched for the error on the net. Seems that the embedded browser xulrunner does not get along with the Eclipse what-ever-the-version which RMC is currently using.

I've tried several trial-and-error solutions:
- set the environment variable with the command "export MOZILLA_FIVE_HOME=/usr/lib/xulrunner-1.9.2.3/", would actually crash the entire RMC Eclipse, with bad bad coredumps :)
- reboot the damn thing after adding more environment variables in the .profile of the current user.
- read the forums and try not to waste precious time mocking with a pretty controllable Eclipse environment on Windows :)

The big thing which fixed it:
1. Make sure you install the xulrunner package using Synaptic. My version is 1.9.2
2. edit the eclipse.ini of the RMC software. In my environment, the command was:

sudo gedit /opt/ibm/rmc75/eclipse.ini

Add the following line:

-Dorg.eclipse.swt.browser.XULRunnerPath=/usr/lib/xulrunner-1.9.2.3


Final note: if you reached this point, you must already know that RMC is by default started as a product with a command such as:
/opt/ibm/rmc75/rmc/rmc
Near the executable you have a rmc.ini file which supports the same fix as above.

Running Method Composer within the Eclipse environment allows me to use multiple workspaces, but this is another story.
