Hello Cory,

Sorry, it did not click the first time: I did fix the RhinoClassLoader 
since 1.5beta4 to address that very issue (now the RhinoClassLoader 
properly delegates to its parent before trying anything). If you get the 
lastest CVS version, you should be able to run your ECMA scripts with 
JavaWebStart.

Vincent.
