Hi,

We are using Servicemix4.
We had the ftp bean specification like below

<ftp:poller service="ns:ftpPoller" endpoint="ftpPollerEndpoint"
                targetService="ns:ftpSender" targetEndpoint="ftpSenderEndpoint"
                
uri="ftp://testftp:[email protected]:21/home/testftp/poller";>
                <property name="marshaler">
                        <bean 
class="org.apache.servicemix.components.util.BinaryFileMarshaler"
/>
                </property>
        </ftp:poller>

        <ftp:sender service="ns:ftpSender" endpoint="ftpSenderEndpoint"
                uri="file:/home/prakash/test/sender">
                <property name="marshaler">
                        <bean 
class="org.apache.servicemix.components.util.BinaryFileMarshaler"
/>
                </property>
        </ftp:sender>

But it is throwing error. The error report in servicemix.log says :-

15:50:43,038 | ERROR | xtenderThread-74 | ServiceAssemblyInstaller         |

I am not getting any idea what to fix?
Is it a configuration issue or servicemix bundle issue or ftp server issue?

Could you please suggest the solution for this.

Thanks.

Prakash
