In a Java-to-.NET project, you've proxied, and are trying to access a .NET class in a System.* namespace (for example, System.Transactions.CommittedTransaction).Your Java IDE or compiler won't let you reference the class.
The problem is that java.lang.System is a standard Java class, and the IDE assumes that any proxy class whose full name begins with System.* is actually a member of java.lang.System.
To work around this problem, add the line
to the start of your Java file. Then, in your code, simply reference CommittedTransaction. It'll now work.
You must do this for every proxy class in a System.* namespace; you can't simply import System.* or System.Transactions.*.
This will even work when your proxy class's name conflicts with the name of a standard Java class. For example, to access the proxy of the .NET class System.Object, simply add
Now, all references to Object in your Java file are to System.Object. (To reference the Java Object class, you'll need to explicitly use the fully qualified name java.lang.Object.)
