Trouble with ExportCommand

Hello,

I'm working with javacvs for the first time.  I'm trying to write a program
to export files from a repository that have been tagged a particular way.
I can connect to the repository just fine.  But, when I execute my
ExportCommand, I get this big exception:

  java.io.IOException: The file exists.

    boolean java.io.Win32FileSystem.createFileExclusively(java.lang.String)
    boolean java.io.File.createNewFile()

    void
org.netbeans.lib.cvsclient.response.SetStickyResponse.process(org.netbeans.lib.cvsclient.util.LoggedDataInputStream,
 org.netbeans.lib.cvsclient.response.ResponseServices)
    void org.netbeans.lib.cvsclient.Client.handleResponse()
    void org.netbeans.lib.cvsclient.Client.processRequests(java.util.List)
    void
org.netbeans.lib.cvsclient.command.export.ExportCommand.postExpansionExecute(org.netbeans.lib.cvsclient.ClientServices,
 org.netbeans.lib.cvsclient.event.EventManager)
    void
org.netbeans.lib.cvsclient.command.export.ExportCommand.execute(org.netbeans.lib.cvsclient.ClientServices,
 org.netbeans.lib.cvsclient.event.EventManager)
    void
org.netbeans.lib.cvsclient.Client.executeCommand(org.netbeans.lib.cvsclient.command.Command,
 org.netbeans.lib.cvsclient.command.GlobalOptions)
    void cvs_test.cvs_test.<init>()
    void cvs_test.cvs_test.main(java.lang.String[])
  Process exited with exit code 0.


Can someone tell by the code below what I could be doing wrong?


static final String USERNAME   = "my_id";
static final String PASSWORD   = "my_password";
static final String HOSTNAME   = "my_server";
static final String REPOSITORY = "/u1/CVSRepository/tms";
static final String CVSROOT    = ":pserver:" + USERNAME + "@" + HOSTNAME +
":" + REPOSITORY;
static final String LOCALPATH  = "D:/MY_MODULE/SQL";
static final String TAG        = "my_tag";
static final String MODULE     = "MY_MODULE";

Client client;
GlobalOptions gOptions = new GlobalOptions();

public cvs_test() {
File workingDir = new File(LOCALPATH);
try {
  if (!(workingDir.exists()))
    workingDir.mkdirs();
  }
catch (Exception e) {
  e.printStackTrace();
  return;
}

PServerConnection connection = new PServerConnection();
connection.setUserName(USERNAME);
connection.setEncodedPassword(StandardScrambler.getInstance().scramble(PASSWORD));
connection.setHostName(HOSTNAME);
connection.setRepository(REPOSITORY);
try {
  connection.open();
  client = new Client(connection, new StandardAdminHandler());
  client.getEventManager().addCVSListener(new BasicListener());
  client.setLocalPath(workingDir.getAbsolutePath());

  gOptions.setCVSRoot(CVSROOT);
}
catch (AuthenticationException e) {
  e.printStackTrace();
  return;
}

// export -r <my_tag> <my_module>
ExportCommand ec = new ExportCommand();
ec.setExportByRevision(TAG);
ec.setModule(MODULE);
System.out.println(ec.getCVSCommand());

try {
  client.executeCommand(ec, gOptions);
}
catch (AuthenticationException e) {
  e.printStackTrace();
}
catch (CommandException e) {
  e.printStackTrace();
}

//  Close the connection.
try {
  client.getConnection().close();
}
catch (Exception e) {
  e.printStackTrace();
}
