Question

I use

<gzip-compress-transformer/>
<base64-encoder-transformer/>

after a file connector, and then write a component to deal with the gzip+base64 content.
How can i get the file name in the component?

Answer 1

Note that we introduced annotations in Mule 3 for doing runtime injection, this means you can specify how to invoke a component without needing transformers i.e.

public void save(@Payload String fileContents, @InboundHeaders(“originalFilename”) String originalFilename)

See: http://www.mulesoft.org/documentation/display/MULE3USER/Creating+Service+Objects+and+Transformers+Using+Annotations
