TheKidCof,
In order to transfer regular text files over the service bus, you should
specify another Marshaler, which transforms the plain text file to an
XML message and back again. You can write your own Marshaler, extending
DefaultFileMarshaler, but ServiceMix also contains
org.apache.servicemix.components.util.SimpleFlatFileMarshaler, which
appears to be what you need. My guess is that you just have to create
the bean (using Spring syntax?) and assign it to the marshaler
attribute, but I have never used it myself, so I don't have any working
code snippets to get you started...
Regards,
Gert

Well, it creates the file in the senders folder however it's empty. This is
the error msg i get. The question is how how can i transfer regular text
files? , non xml files.
What I would like to do is this , have service mix polling via ftp a folder
for files on another computer and transfer the files to my local computer,
then once the file arrives have servicemixFTP scan the directory for the
files and once it picks up the files, send a message VIA JMS to a webservice
or EJB(3.0) stateless, then i will process the files. I'm using geronimo 2.0
m3(my own complied version, I fixed a few bugs in it already.) This is my
goal. The problem is I have never worked with serviceMIX and it's hard to
find books or documents on how things work in serviceMIX when it comes to
serviceMIX-FTP or File.
In advance, Thank you again for all your help.

TheKidCof,
In the previous example, the file was copied from one FTP location
(referred to by <ftp:poller/>) to another (the <ftp:sender/>)
If you want to store the files in a local directory, you'll have to
create a second SU, using servicemix-file. Create the zip file
(my-file-su.zip) which contains an xbean.xml file like this
<beans xmlns:file="http://servicemix.apache.org/file/1.0";
xmlns:my="http://my.own/smx";>
<file:sender service="my:file-sender" endpoint="endpoint"
uri="..." />
</beans>
Add my-file-su.zip to your service assembly and update META-INF/jbi.xml to
reflect the additional SU, adding this <service-unit/> block:
<service-unit>
<identification>
<name>my-su</name>
<description>My First :: File Service Unit</description>
</identification>
<target>
<artifacts-zip>my-file-su.zip</artifacts-zip>
<component-name>servicemix-file</component-name>
</target>
</service-unit>
Now, you can change the targetService and targetEndpoint attribute of the
<ftp:poller/> element to connect it to your <file:sender/> to finish up
your configuration.
Is this the information you were looking for?

Gert

Hey Gert,
Thank you so much for your help. It worked, however where does it
copy the file to? I want the FTP component to copy a text file to
directory
of my choosing. How do i get the xbean to configured to ftp the file to
the
folder of my choice?
If you could help me out that would be great.

<ftp:poller service="my:poller" endpoint="endpoint"
targetService="my:sender" targetEndpoint="endpoint"
uri="..." />
<ftp:sender service="my:sender" endpoint="endpoint"
uri="..." />
</beans>
Next, create a zip file (my-sa.zip) which contains the previous ZIP file
and META-INF/jbi.xml:
<jbi xmlns="http://java.sun.com/xml/ns/jbi"; version="1.0">
<service-assembly>
<identification>
<name>my-sa</name>
<description>My First :: SA</description>
</identification>
<service-unit>
<identification>
<name>my-su</name>
<description>My First :: FTP Service Unit</description>
</identification>
<target>
<artifacts-zip>my-su.zip</artifacts-zip>
<component-name>servicemix-ftp</component-name>
</target>
</service-unit>
</service-assembly>
</jbi>
Now, install the servicemix-ftp component (just copy the installer zip
you find in /components to /deploy) and any required components. If
everything is OK, just copy the my-sa.zip to the /deploy directory and
you should be up and running.
Hope this helps,
Gert

above
mentioned link aren't detailed enough for me.
I am new to service mix therefore anyhelp would be greatly appreciated.
