File Transfer

[ptjcarlo]

Hi guys,

Would you recommend to use switchyard on creating a file transfer service?

I want to create a simple switchyard project that can transfer a file from my local directory and pass it on a FTP server?

Any best practice that you can suggest?

Many Thanks,

Hi,

I would probably use a:

• File service
• Camel component
• FTP reference

With this should be straight forward to implement.

Thanks Jorge

I tried to create java class that implements getting a file in a local directory and put it in ftp server. However, got an error message while enabling the service in EAP,

"Internal Server Error

{

    "outcome" => "failed",

    "failure-description" => {"JBAS014671: Failed services" => {"jboss.deployment.unit.\"FileToFTP_proj-0.0.1-SNAPSHOT.jar\".SwitchYardService" => "org.jboss.msc.service.StartException in service jboss.deployment.unit.\"FileToFTP_proj-0.0.1-SNAPSHOT.jar\".SwitchYardService: org.switchyard.SwitchYardException: SWITCHYARD030412: Unknown Service name '{urn:com.example.switchyard:FileToFTP_proj:1.0}FTPUploaderService'.

File/FTP binding and Java Interface (FTPUploaderService') -> Java Bean component (FTPUploaderServiceBean_new)

Hi Carlo,

I don't know how you are progressing with this, but it should be easier than that.

Just to get you started:
