Help Writing File and Members to AS/400

["Jateen Patel" <patel_jateen@xxxxxxxxxxx>]

HI! All,

I am new to the AS/400 world and would sincerely appreciate any help I can 
get for the following.

I want to write a java class (which would run on the AS/400) that would 
accept a fileName, fileMemberName and pContents. The class should then 
create a file with the fileName, if it does not already exist and then add a 
member with name fileMemberName. Then it should write the String pContents 
to the member just created. The length of pContents can be different for 
different members in the same file.  The class i wrote below throws a file 
already exists exception when I call the methog writeFileOnAS400() for the 
second time.

All help appreciated...Thanks




import com.ibm.as400.access.*;

public class AS400Utility
{

public static void writeFileOnAS400(String pFileName, String 
pFileMemberName, String pContents ) throws Exception
{
AS400 as400 = new AS400();
String as400FileName = "/QSYS.LIB/IQFILES.LIB/" + pFileName + ".FILE";
String as400MemberName = pFileMemberName + ".MBR";

// Create a file object that represents the file
SequentialFile newFile = new SequentialFile(as400, as400FileName + "/" + 
as400MemberName);

// Create the file
newFile.create(pContents.getBytes().length, "*DATA", "Data file created with 
" + pContents.getBytes().length + "byte record." );


// Open the file for writing only.
// Note: The record format for the file
// has already been set by create()
newFile.open(AS400File.WRITE_ONLY, 0, AS400File.COMMIT_LOCK_LEVEL_NONE);


// Write a record to the file. Because the record
// format was set on the create(), getRecordFormat()
// can be called to get a record properly formatted
// for this file.
Record writeRec = newFile.getRecordFormat().getNewRecord();
writeRec.setField(0, pContents);
newFile.write(writeRec);


// Close the file since I am done using it
newFile.close();

// Disconnect since I am done using
// record-level access
as400.disconnectService(AS400.RECORDACCESS);

}

public static void main(String args[])
{
System.out.println("Writing file to AS400...");
try
{
writeFileOnAS400("BPL0000004", "M001", "<SampleXML>The sample file 
1</SampleXML>");
System.out.println("Finished writing file 1");
writeFileOnAS400("BPL0000004", "M002", "<SampleXML>The sample file 2 is 
larger than sample file 1</SampleXML>");
}
catch(Exception e)
{
e.printStackTrace();
}
System.out.println("Completed file writing to AS400...");
}
}
