1- idlj is the tool that shipped with jdk 1.3 and higher releases, and used by ORBD which also shipped by JDK 1.3, and its usually used for just testing, and usually testing java-to-java corba, it doesn't have many features that CORBA supports-which called CORBA services- like security,life sycle,concurrency control,transaction service and many others....it's just include the Naming service, but idl2java which is shipped with visibroker is a complete tool, and if you try the both tools you will see that the classes generated by idl2java is different than the classes generated by idlj, like you will never see the bind() methods in the Helper classes generated by idlj but you will see them in the Helper classes generated by idl2java,

2- I think that visibroker is a very good tool, but there are others like OrbixWeb, and there is also an ORB tool in IBM websphere.



I hope this will help you
