I have experienced certain error on coldfusion 8, when trying to instantiate a webservice:
ws = createObject("webservice","http://localhost/test.cfc?wsdl");
The error that I receive is the following:
coldfusion.jsp.JavaCompiler$UnknownCompiler: Unable to run the internal Java compiler: java.lang.NoClassDefFoundError: javax/tools/StandardJavaFileManager.


I remember reading a couple weeks ago, on Ars Technica, I think that a developer ported Java 6 for Leopard on his own.
