Compiling java files which has other Imports

Hi All,

I have imported another java file from a package (jar file). This
package is converted into a static ibrary .a
If I compile the HelloWorld.java which has the import com.test.Hello. it fails.

import com.test.Hello;

class HelloWorld
{
   HelloWorld()
   {
       Hello tst = new Hello();
       tst.printMessage();
   }
}

-gcj -c HelloWorld.java

-gcj -c HelloWorld.java -L. -lNatHello.a

Can anyone please help me

Thanks
