Example: Using record-level access (part 2 of 2)

[ Previous part ]

Use the following as an example for your program.

import java.io.*;
import java.util.*;
import com.ibm.as400.access.*;

public class RLACreateExample
{
  public static void main(String[] args)
  {
    AS400 system = new AS400(args[0]);
    String filePathName = "/QSYS.LIB/MYLIB.LIB/MYFILE.FILE/MBR1.MBR";  Note 1 

    try
    {
      SequentialFile theFile = new SequentialFile(system, filePathName);
	  
      // Begin Note Two
      CharacterFieldDescription lastNameField = 
         new CharacterFieldDescription(new AS400Text(20), "LNAME");
      CharacterFieldDescription firstNameField = 
         new CharacterFieldDescription(new AS400Text(20), "FNAME");
      BinaryFieldDescription yearsOld = 
         new BinaryFieldDescription(new AS400Bin4(), "AGE");

      RecordFormat fileFormat = new RecordFormat("RF");
      fileFormat.addFieldDescription(lastNameField);
      fileFormat.addFieldDescription(firstNameField);
      fileFormat.addFieldDescription(yearsOld);

      theFile.create(fileFormat, "A file of names and ages");  Note 2 
      // End Note Two


      theFile.open(AS400File.READ_WRITE, 1, AS400File.COMMIT_LOCK_LEVEL_NONE);

      // Begin Note Three
      Record newData = fileFormat.getNewRecord();
      newData.setField("LNAME", "Doe");
      newData.setField("FNAME", "John");
      newData.setField("AGE", new Integer(63));

      theFile.write(newData);  Note 3 
      // End Note Three
      
      theFile.close();
    }
    catch(Exception e)
    {
      System.out.println("An error has occurred: ");
      e.printStackTrace();
    }

    system.disconnectService(AS400.RECORDACCESS);

    System.exit(0);
  }
}

1. (args[0]) in the previous line and MYFILE.FILE are pieces of code that are prerequisites for the rest of the example to run. The program assumes that the library MYLIB exists on the server and that the user has access to it.
2. The text within the Java™ comments labeled "Begin Note Two" and "End Note Two" shows how to create a record format yourself instead of getting the record format from an existing file. The last line in this block creates the file on the server.
3. The text within the Java comments labeled "Begin Note Three" and "End Note Three" shows a way to create a record and then write it to a file.
