[jcifs] Problem connecting to a samba file share

[Hite, Sharon (NIH/NIEHS) [E]]

I am trying to troubleshoot a problem connecting to a samba file share.
I can connect manually, but when I use JCIFS to connect, I get this
message:

 

[2009-02-09 16:49:05,648] ERROR appLog The specified share name
//devwww/devwww cannot be found.

My application has had no problems connecting for over two years so I
don't think it's my code.  However, I need some ideas on where to look
to resolve this issue.  For reference, here is the code I use to test
connections:

 

        jcifs.Config.setProperty( "jcifs.netbios.client.writeSize",
"65535");

        jcifs.Config.setProperty( "jcifs.netbios.client.snd_buf_size",
"60416");

        jcifs.Config.setProperty("jcifs.smb.lmCompatibility","3"); //
Allows use of LMv2

        jcifs.Config.setProperty("jcifs.netbios.wins",props.getIp());

 
jcifs.Config.setProperty("jcifs.smb.client.username",props.getUsername()
);

 
jcifs.Config.setProperty("jcifs.smb.client.password",props.getPassword()
);

 
jcifs.Config.setProperty("jcifs.smb.client.domain",props.getDomain());

 

            try {

                appLog.debug("Testing connection to the share " +
fileShare;

                //noinspection UNUSED_SYMBOL

                SmbFileInputStream in = new SmbFileInputStream("smb:" +
fileShare + "/index.cfm");

            } catch (SmbException e) {

                appLog.error("The specified share name " +
props.getFileShares(i) + " cannot be found.",e);

                System.exit(-1);

            } catch (MalformedURLException e) {

                appLog.fatal("MalformedURLException testing file share "
+ props.getFileShares(i),e);

                System.exit(-1);

            } catch (UnknownHostException e) {

                appLog.fatal("UnknownHostException testing file share "
+ props.getFileShares(i),e);

                System.exit(-1);

            } catch (IOException e) {

                appLog.fatal("IOException testing file share " +
props.getFileShares(i),e);

                System.exit(-1);

            }
