We have a sample for JavaScript which could be converted for Java. And it could also be enhanced for CPP as well. But no we don't currently have pre-defined ones set up.
Sorry we don't currently have any new sample language definitions that have been added. But if you take a look at and copy the ActiproSoftware.CSharp.xml file, you'll see it's pretty easy to change the keywords, etc. around from C# to C++ and meet your needs.
