How to Update jsch.jar

Anonymous — Thu, 01 Sep 2016 09:53:02 GMT

Hi,
I'm still using TOS 6.1.1 on Windows 7.
I have problem with FTP connection like this:

Exception in component tFTPConnection_1
com.jcraft.jsch.JSchException: Algorithm negotiation fail

I ve found the solution - upgrade jsch-0.1.51 to jsch-0.1.54.
How can I do this ?

Hi,
Could you please try to rename your new .jar file with the old one(rename jsch-0.1.54 as jsch-0.1.51) and restart your studio to see if it works?

Best regards

I had the same issue using TOS 6.1 to connect to a FTP with implicit TLS.

I had the sftp support checked.

Following this thread, I downloaded jsch-0.1.55, copied it into D:\Talend\TOS_DI-20151214_1327-V6.1.1\workspace\.Java\lib and renamed it jsch-0.1.51.jar. After restzrting the studio, same issue.

I then copied it to D:\Talend\TOS_DI-20151214_1327-V6.1.1\configuration\.m2\repository\org\talend\libraries\jsch-0.1.51\6.0.0-SNAPSHOT to replace the existing jsch-0.1.51-6.0.0-SNAPSHOT.jar

It now works after restarting the studio

Hope it helps !
