WSO2 ESB - writing files out of base64

Question

I have a proxy which accepts XML files with Base64 encoded files in it. For example the XML looks like:

  Hello World

        

Answer 1

You have several options,

1. If file sizes are small, iterate through <attachments> and for each attachment, decode using the script mediator and write to a file with syntax like,
   

   <property name="transport.vfs.ReplyFileName"
             expression="expression-to-compute-file-name"
             scope="transport"/>
   <property action="set" name="OUT_ONLY" value="true"/>
   <send>
       <endpoint>
           <address uri="vfs:file:///home/user/test/out"/>
       </endpoint>
   </send>
   

2. If the files are large then it's more efficient to write your own class mediator

Answer 2

Send the files to an local filesystem . Use VFS proxy
