There's no problem with not included classes here. So that's not needed.

You are still providing insufficient information to efficiently help 
you. What version of JavaNativeCompiler are you using? What version of 
mysql? Where can it be downloaded? How did you compile?

Guessing all this, I now took
- JNC v1.1.1 with gcc-122233-win (compiles for Windows)
- MySQL Connector/J 5.1 from http://dev.mysql.com/downloads/#connector-j
and tried to compiled the jar. java.sql.SQLClientInfoException does not 
yet exist in GCJ (indeed it's quite new that class).

So, downgraded to MySQL Connector/J 5.0. Here some com.mchange classes 
and org.jboss classes are missing. Using -findirect-dispatch helps here 
and should solve the problem (I guess these classes are never needed at 
runtime since a Sun JRE doesn't have them either).

This class exists in recent GCJs. What version are you using? Please update.


Again: Please, always add all information so that people willing to help 
you can fully reproduce the problem.


Hope that helps
