Embedded DSL support

Hello,

I use the Netbeans JavaCC plugin very often. However, it misses a lot of features, such as parsing, code completion etc. Therefore, I want to write a new JavaCC plugin. The syntax of the domain specific language (DSL) of JavaCC is not the problem. The problem is, that JavaCC code wraps Java code. I would be interessted if there is a possibility in Netbeans DSL modules to tell Netbeans: "if you come here, use the formatting options, parser, lexer etc. that is available for language X, in this case Java". I do not want to write a complete Java lexer and parser again. I think there must be a possibility to embedd the Java DSL in the JavaCC DSL. Perhaps, some can give me a hint how this could work.
Thanks.

Regards,
Klaus
