Dear all,
I traced the codes and found something strange. When issuing
"extendedTransfer", it creates a "FeatureList" object. The following
is the constructor
public FeatureList(String featReplyMsg) {
featVector = new Vector();
StringTokenizer responseTokenizer
= new StringTokenizer(featReplyMsg,
System.getProperty("line.separator"));
// ignore the first part of the message
if (responseTokenizer.hasMoreElements()) {
responseTokenizer.nextToken();
}
while ( responseTokenizer.hasMoreElements() ) {
String line = (String) responseTokenizer.nextElement();
line = line.trim().toUpperCase();
if ( !line.startsWith( "211 END" ) ) {
featVector.add( line );
...
I found it's because "System.getProperty("line.separator")" returns
null. In Unix system, it's supposed to return "\n". Does anyone knows
why?
Best regards,
Fu-Ming

Subject: some problem about gridftp client
To: [email protected]
Hello, all,
I tried to use gridftp client(java version) to transfer files.
However, I got NullPointerException when transferring files. I tried
to check the string and it looked like the string on the control
channel will be dealed with by StringTokenizer. Because I checked the
string, it is "211-Extensions supportednull UTF8null LANG ENnull
DCAUnull PARALLELnull SIZEnull MLSTnull
Type*;Size*;Modify*;Perm*;Charset;UNIX.mode*;UNIX.owner*;UNIX.group*;Unique*;UNIX.slink*;null
ERETnull ESTOnull SPASnull SPORnull REST STREAMnull MDTMnull 211
Endnull" and there is no delimiter.
I also checked the message on gridftp server. please refer the following

I also tried to compare these information with other message and found
there are more information afer "211 End". Does anyone knows what's
going on??
