How to generate jasper report in pdf format using swing

Question

hi all,
im new to swing and jasper.. can anybody provide me some example on how to generate the jasper report in pdf format? i will call the reportManager from sessionBean.. below is my code:
1)delegate:
public GenerateReportDto generateIntoPdfReport(String fileName, String outputFileName, Map parameters){
GenerateReportDto generateReportDto = getAuditTrailServiceRemote().generateIntoPdfReport(fileName, outputFileName, parameters);
return generateReportDto;
2)sessionBean:
public GenerateReportDto generateIntoPdfReport(String fileName, String outputFileName, Map parameters){
//Map parameters = new HashMap();
ReportManager reportManager = new ReportManager();
3)ReportManager()
public void generateIntoPdfReport(String fileName, String outputFileName, Map parameters) {
          Connection conn = null;
          try {
               conn = dataSource.getConnection();
               //Generate the report to bytes
               File reportFile = new File(fileName);               
               byte[] bytes =
                    JasperRunManager.runReportToPdf(
                         reportFile.getPath(),
                         parameters,
                         conn
          //conn.close();
          //Write the bytes to a file
          ByteBuffer buf = ByteBuffer.wrap(bytes);
          File file = new File(outputFileName);
          // (if the file exists)
          boolean append = false;
          // Create a writable file channel
          FileChannel wChannel = new FileOutputStream(file, append).getChannel();
          // Write the ByteBuffer contents; the bytes between the ByteBuffer's
          // position and the limit is written to the file
          wChannel.write(buf);
          // Close the file
          wChannel.close();
          } finally {
               if (conn != null) {
conn.close();
Any help would be highly appreciated. Thanks in advance

Hi ,
One 'simple' way is by using the DBMS_SCHEDULER db package and the procedure CREATE_JOB(....) using as job_type the value 'EXECUTABLE'...
Read for further info in 'PL/SQL Packages and Types Reference'.
If you have access to OEM ... you can configure this there using wizard.....
Other way is to use the External Procedure call capabiblity of Oracle DB Server...:
