Hello

I played around with the maven-nar-plugin that was recommended on this
list. The below pom.xml does produce .h files from the java classes and
also compiles the C files. What's missing though is a way to get a 
.h from "java.sql.Types" as this class is in the JRE's rt.jar and not
in the specified <classDirectory>. Any ideas?

bye,

-christian-

P.S.: Beware the hardcoded paths and Postgres version numbers. Don't
      know yet how to integrate pg_config in maven.

P.P.S.: Directoy layout for the C files is:

	./src/main
	./src/main/c
	./src/main/c/type
	./src/main/include
	./src/main/include/pljava
	./src/main/include/pljava/type
