Protocol error: root request missing

I'm working to incorporate the JavaCVS library into a project I'm working on, but whenever I try to update a file or list of files, I keep getting the error in the subject.

The code I'm using to connect and do the update is listed below, and the cvs server is running cvs version 1.11.1p1

Any help on this matter would be greatly appreciated.

Thanks,

if(m_client == null)
	{
	m_client = new Client(m_connection, new StandardAdminHandler());
	
	m_client.getEventManager().addCVSListener(this);
}
		
UpdateCommand com = new UpdateCommand();
com.setFiles(files);
com.setRecursive(true);
	
GlobalOptions options = new GlobalOptions();
options.setCVSRoot(":pserver:"+m_user+"@"+m_server+":"+m_repositoryPath); 
		
try {
	m_client.executeCommand(com,options);
} catch (CommandException e) {
	e.printStackTrace();
	return COMMAND_EXCEPTION;
} catch (AuthenticationException e) {
	e.printStackTrace();
	return INVALID_PASSWORD;
