    Camel 2.5/2.6 - FTP Endpoint not working on ESB 4.3.0/4.3.1

    Rob Stoner Newbie

      Hi all,

       

      I am trying to run the camel-example-osgi sample (for both Camel 2.5 and 2.6).  It runs with a "timer", "log", "bean" or "file" endpoint, but when I change the endpoint to "ftp", and install the bundle, it immediately dumps out a type not present exception. 

       

      Sample Code:

       

         features:list | grep -v uninstall

      Any suggestions would be appreciated,

       

      Thanks,

      (PS, in Camel 2.2 and 2.3, this application builds and runs with a local FTP server, however does not retrieve files from the remote server I am making a request to.  The stepwise functionality from 2.6 would be nice to have.)

          Can you try stopping the server. clear the data folder. And start server again.

            L.S.,

             

             

            Could you paste the full Spring XML configuration file you're using?  I have just tried this locally with 4.3.1-fuse-00-00 and the file below seems to work fine on my machine:

             

            <beans xmlns="http://www.springframework.org/schema/beans"

                  <log message="Processing ${file:name}"></log>
                </route>
              </camelContext>
            
            </beans>   
            

             

             

            Regards,

             

            Gert

             

             

            P.S. Feel free to replace '&#38;' with '&amp;' - substitution happened automatically when I copy-pasted this in here

              Thanks for the responses.  After stopping the server, clearing out the data directory, starting the server and running Gert's code as posted, I get this exception:

              Which is slightly different. 

               

              All features, including camel-ftp installed without error before running this sample. 

               

              Any ideas?

               

              thanks,

                L.S.,

                 

                 

                I was able to reproduce this using OSGi bundle packaging instead of deploying a plain Spring XML file as I was doing before and then got things working again with a little hack to the MANIFEST.MF information.

                 

                If you add either one of these, it works fine on my machine:

                - a Require-Bundle for org.apache.camel.camel-core and org.apache.camel.camel-ftp

                - an Import-Package for the missing type reported in the original exception (org.apache.camel.component.file.strategy)

                 

                The reason this works fine with the plain Spring XML approach is because that comes with a DynamicImport-Package=* to allow things to get wired to any package in the system.

                 

                Anyway, we also want to get this working out-of-the-box again without any additional MANIFEST tinkering, so I raised http://fusesource.com/issues/browse/MR-420 to ensure we don't forget to look into this.

                 

                 

                Thanks for taking the time to report this,

                  I have attached a patched JAR to the ticket

                  http://fusesource.com/issues/browse/MR-420

                   

                  You can override this JAR file in the system/org/apache/camel/camel-ftp ... directory.

                   

                  You would need to stop the server.

                  Override the JAR

                  And start the server again.

                   

                  Pay attention if you reinstall the server/camel-ftp feature it may re-download the original JAR, which mean you would have to patch the JAR again.
