Susmit Sarkar commented on SSHD-1209:
-------------------------------------
Welcome to the community
The version is 2.7.0 it's mentioned above.
You can have a look at this class
[https://github.com/apache/mina-sshd/blob/2fc98f7a21a7b83d2b2bc72d48a2194caa7f8fd1/sshd-contrib/src/main/java/org/apache/sshd/contrib/server/subsystem/sftp/DetailedSftpErrorStatusDataHandler.java]
only difference is I have implemented is adding few more interfaces:
ChannelSessionAware, AsyncCommandErrorStreamAware, CommandDirectErrorStreamAware
to write any sftp related exception to the command line output, and have
overrwritten few default methods
resolveErrorMessage() and setIoErrorStream(IoOutputStream errStream)
> Write to error stream for custom exception is appending a extra word at the
> beginning

> Hello Team,
>
> We have a class as below
>
> {code:java}
> DetailedSftpErrorStatusDataHandler implements SftpErrorStatusDataHandler,
> ChannelSessionAware, DetailedSftpErrorStatusDataHandler implements
> SftpErrorStatusDataHandler, ChannelSessionAware,
> AsyncCommandErrorStreamAware, CommandDirectErrorStreamAware {
> {code}
> and we have overridden the :
>
> resolveErrorMessage and setIoErrorStream(IoOutputStream errStream)
> {code:java}
> @Override
> public void setIoErrorStream(IoOutputStream errStream) {
> this.errStream = errStream;
> }
> {code}
> finally we are writing to the error stream:
> {code:java}
> private void writeMsgToErrorStream(String refinedUserExitMessage) {
> ByteArrayBuffer buf = new ByteArrayBuffer();
> buf.putString(refinedUserExitMessage +
> System.getProperty("line.separator"));
> try { if (errStream != null) {
> errStream.writeBuffer(buf);
> }
> } catch (Exception e) {
> }
> }
> {code}
> Once the data is written to error stream we are gettig proper message to the
> console:
> !image-2021-08-19-12-50-01-922.png!
> But there is an extra charater getting appended at the first character *<*
> Utils.java ....
> I have no idea from where this *<* is coming from, and that changes with the
> first character like if it is P it would be *>, when starting with S it gets
> appended with Z*
> Any help will be appreciated.
> Thanks,
> Susmit
