I have set up the Equinox p2 installer. The URL ishttp://jmoney.sf.net/installer/jmoney.jnlp. All the Equinox p2 and Eclipse stuff works very well. Unfortunately I am having terrible trouble with webstart, and it is very unreliable, though it used to work for me . But then I have never been able to get webstart to work.
If webstart is not working for you then you can also try it out by downloading version 3.4.1 of the Equinox p2 installer, then edit p2installer.ini and point the install description tohttp://jmoney.sourceforge.net/installer/jmoney-installer.properties (instead of the Eclipse SDK installation properties file). I think you will find that reliable on any platform and you will get a p2 enabled installation of JMoney.
