Question

Is it possible to invoke sftp outbound endpoint, and send a file, through the code?
I have a reference to a File object in java code (in a custom transformer), and I want to invoke sftp outbound endpoint and pass that File reference. Is this doable?
Thanks.

Pass it a FileInputStream, that should work.

muleContext.getClient().dispatch("sftp://...", new FileInputStream(file), null);

If not, you’ll have to pass it a byte[].

Note that dispatch is asynchronous: the call will return immediately while the SFTP communication occurs. if you want to wait until it’s done, use send with a time-out as last parameter.

Since you have several SFTP connectors configured, you’ll have to specify the connector name in the URL. Supposing you want to dispatch using SFTP_Upload_Connector, you’ll have to use:

muleContext.getClient().dispatch("sftp://...?connector=SFTP_Upload_Connector", new FileInputStream(file), null);

If you want to set a particular destination file name, pass it as a property named filename in the properties map, for example using:

muleContext.getClient().dispatch("sftp://...?connector=SFTP_Upload_Connector", new FileInputStream(file), Collections.singletonMap("filename", "somen_ame"));
