Do u mean another jsch bundle or another camel-ftp bundle?

Anyways, the only other jsch bundle that exported com.jcraft.jsch has been
stopped which I guess should have same effect has uninstalling.

No， you should uninstall it.
If you just stop the bundle, the export packages of that bundle can 
still be resolved.


There is no other camel-ftp bundle in Servicemix.

Kindly guide me through how best to resolve this.

rgds.

camel-ftp feature to install the bundle,

If I remember right, we didn't fix the camel-sftp bundle issue by 
upgrading the jsch bundle before camel 2.2.0 released.

Can you check if there is another bundle which exports the 
com.jcraft.jsch package ?

If so , you need to uninstall that bundle.

This is what camel-ftp headers look like:

And this is what my jsch headers looks like:

Bundle 246

Import-Package = com.jcraft.jzlib;resolution =

Export-Package =

com.jcraft.jsch,javax.crypto.spec,javax.crypto,javax.crypto.interfaces";version=
"0.1.42"

Am I missing something? Or may be you can point to me where I can
download
the right jsch.

Thanks.

Hi Lekkie,

Could you remember me some informations such as:
- the ServiceMix version that you use
- if you use JBI, your xbean and Camel route builder

Did you check if no other jsch jar is present in the classloader ?

I checked in Camel 2.2.0, in the FTP component and the jsch version used
is the 0.1.40.
You can have a look here:
http://svn.apache.org/repos/asf/camel/tags/camel-2.2.0/components/camel-ftp/pom.xml

JB
