Hi,

This is a post about the jcifs-1.2.1 library. If the post is for the wrong 
product/version, I'm sorry. I couldn't find the correct classification for this 
(possible) bug.

In short : the jcifs-1.2.1 NTLM filter works on Tomcat but fails on Weblogic.
In detail :
I believe that at startup, the jcifs-1.2.1 NTLM filter tries to connect to 3 
possible ports on the domain controller server: 0, 139 and 445.
A ConnectException is 'catch-ed' for each attempt.

With tomcat4.1/jre 1.4.2, a ConnectException is indeed thrown and handled, but 
BEA Weblogic 7.0 throws a SocketException ! (see stack trace below)

I replaced the ConnectException with SocketException in the code 
(jcifs.smb.SmbTransport.java, method doConnect, line 274) and all works fine 
now.

I also reviewed sun's doc on the Socket constructor and it can throw an 
IOException, so even my change won't cover all possible Exceptions.

I'm going to continue to work with my own fix, but if it's wrong, I would 
appreciate if you could let me know. Otherwise I assume that this will get 
fixed in a next release and will use my own patch until then.

Thank you !

Changed in SmbTransport.java at line 274 :

        try {
            negotiate( port, resp );
        } catch( SocketException ce ) { // changed from ConnectException !
            port = port == 445 ? 139 : 445;
            negotiate( port, resp );
        }
