Thomas.
Thank you.
I resolved WARNING message problem.
LargeObject needed close().
It was simple problem.
--- Solved
import java.sql.SQLException;
import java.util.logging.Logger;
import org.postgresql.pljava.internal.LargeObject;
public class CreateOidTest {
public static int createOid() {
try {
LargeObject obj = LargeObject.create(LargeObject.INV_WRITE);
Logger.getAnonymousLogger().info("create OID");
obj.close(); // needed
} catch (SQLException e) {
e.printStackTrace();
}
return 1;
}
}

Thank you,
