Create the .jar file

The createJar() method compiles the class files you specify in the classnames list. The files in the list must have the .class extension.

public String createJar(UDTMetaData mdata, String[] classnames) 
   throws SQLException;

The driver creates a JAR file named sqlname.jar (where sqlname is the name you specified by calling UDTMetaData.setSQLName()) and returns the file name to your application.
