I am getting this exception when attempting to read from a named pipe :
jcifs.smb.SmbException: No description available. Please update error string
for errorCode=233
java.lang.Throwable(java.lang.String)
java.lang.Exception(java.lang.String)
java.io.IOException(java.lang.String)
jcifs.smb.SmbException(int)
void jcifs.smb.SmbTransport.send(jcifs.smb.ServerMessageBlock,
jcifs.smb.ServerMessageBlock)
void jcifs.smb.SmbSession.send(jcifs.smb.ServerMessageBlock,

void jcifs.smb.SmbTree.send(jcifs.smb.ServerMessageBlock,

void jcifs.smb.SmbFile.send(jcifs.smb.ServerMessageBlock,
jcifs.smb.ServerMessageBlock)
int jcifs.smb.SmbFileInputStream.read(byte [], int, int)
int jcifs.smb.SmbFileInputStream.read(byte [])
int java.io.InputStreamReader.fill(char [], int, int)
int java.io.InputStreamReader.read(char [], int, int)
void java.io.BufferedReader.fill()
java.lang.String java.io.BufferedReader.readLine(boolean)
java.lang.String java.io.LineNumberReader.readLine()
com.esuccess.citadel.test.sysadmin.Test(java.lang.String [])
void com.esuccess.citadel.test.sysadmin.Test.main(java.lang.String [])
The code is as follows:
try {
SmbNamedPipe pipe =
new SmbNamedPipe(
"smb://ryan:madeup@hammerhead/IPC$/tran.dat",
SmbNamedPipe.PIPE_TYPE_RDWR);
InputStream is = pipe.getNamedPipeInputStream();
OutputStream os = pipe.getNamedPipeOutputStream();
InputStreamReader isr = new InputStreamReader(is);
OutputStreamWriter osw = new OutputStreamWriter(os);
BufferedWriter bw = new BufferedWriter(osw);
LineNumberReader lnr = new LineNumberReader(isr);
PrintWriter pw = new PrintWriter(bw, true);
for (int i = 0; i < 10; i++) {
pw.println(TRAN_RECORD);
// Thread.sleep(1000);
String s = lnr.readLine();
System.out.println(s);
}
} catch (Exception e) {
e.printStackTrace();
}
The first iteration works, but on the second iteration the exception is
thrown. If I put the "sleep" for 1 second in, I don't get the exception. I
have narrowed it down to this part of the SmbTransport.send method :
switch (response.errorCode & 0xFF) {
case SmbException.SUCCESS :
break;
case SmbException.ERRDOS :
switch ((response.errorCode >> 16) & 0xFFFF) {
case SmbException.ERRnoaccess :
throw new SmbAuthException(response.errorCode);
}
throw new SmbException(response.errorCode);
<<<<<<<<<<<<<<<----------------
case SmbException.ERRSRV :
switch ((response.errorCode >> 16) & 0xFFFF) {
case SmbException.ERRbadpw :
case SmbException.ERRaccess :
case SmbException.ERRaccountExpired :
The value of response just before the exception is thrown is :
SmbComReadAndXResponse[command=SMB_COM_READ_ANDX,received=true,errorCode=No
description available. Please update error string for
errorCode=233,flags=0x0098,flags2=0x8001,tid=2048,pid=19719,uid=2048,mid=7,w
ordCount=0,byteCount=0,andxCommand=0xFF,andxOffset=0,dataCompactionMode=0,da
taLength=0,dataOffset=0]
The value of request just before the exception is thrown is :
SmbComReadAndX[command=SMB_COM_READ_ANDX,received=false,errorCode=0x00000000
,flags=0x0018,flags2=0x8001,tid=2048,pid=19719,uid=2048,mid=7,wordCount=12,b
yteCount=0,andxCommand=0xFF,andxOffset=0,fid=2048,offset=72,maxCount=4096,mi
nCount=4096,openTimeout=-1,remaining=0,offset=4096]
I am running within IBM VisualAge for Java 3.5 on Windows NT Workstation
4.0, and the process on the other end of the named pipe is a native NT
application running on locally on my machine.
Please let me know if you need any more information.
