You can use ProcessBuilder. This code launches sql*plus and runs the script in the 'filename' variable. It displays the results in NetBeans console.
import java.io.BufferedReader;
import java.io.InputStreamReader;
import java.io.File;
import java.util.Map;
public class test1 {
    public static void main (String args []) {
        test_script();
    public static void test_script () {
        String fileName = "@test_table.sql";
        String sqlPath = "E:\\";
        String sqlCmd = "sqlplus";
        String arg1   = "user/password@sid"; -- plug in your user, password and db name
        String arg2   = fileName;
        try {
            String line;
            ProcessBuilder pb = new ProcessBuilder(sqlCmd, arg1, arg2);
            Map<String, String> env = pb.environment();
            env.put("VAR1", arg1);
            env.put("VAR2", arg2);
            pb.directory(new File(sqlPath));
            pb.redirectErrorStream(true);
            Process p = pb.start();
          BufferedReader bri = new BufferedReader
            (new InputStreamReader(p.getInputStream()));
          BufferedReader bre = new BufferedReader
            (new InputStreamReader(p.getErrorStream()));
          while ((line = bri.readLine()) != null) {
            System.out.println(line);
          bri.close();
          while ((line = bre.readLine()) != null) {
            System.out.println(line);
          bre.close();
          System.out.println("Done.");
        catch (Exception err) {
          err.printStackTrace();
}Here is the contents of the script placed at E:\\test_table.sql
Prompt drop TABLE ANOTHER_TEST;
DROP TABLE ANOTHER_TEST CASCADE CONSTRAINTS
Prompt Table ANOTHER_TEST;
CREATE TABLE ANOTHER_TEST
