Mule: Two file outbound endpoint and one inbound endpoint to the same location issue

Question

<flow name="flow1"..>

  <file:outbound-endpoint path="${workdir}/folder/inbox"/>
  ..
  ..
</flow>

<flow name="flow2"..>
  ..
  <file:outbound-endpoint path="${workdir}/folder/inbox"/>

=================================================

My first two flows are have the same file outbound endpoint path and my third flow's inbound endpoint path is pointing to same folder location. I get the error:

=================================================

Can I have two outbound endpoints in a single flow, whose path is same as as inbound endpoint of another flow path?

<flow name="flow1"..>
  ..
  <file:outbound-endpoint path="${workdir}/folder/inbox"/>
  ..
  ..
  <file:outbound-endpoint path="${workdir}/folder/inbox"/>
  ..
</flow>

Answer 1

Try disabling streaming in your file connector:

<file:connector name="sampleFileConnector"  streaming="false" ></file:connector> 

Then in all of your file endpoints refer this connector.

<file:outbound-endpoint connector-ref="sampleFileConnector" path="${workdir}/folder/inbox"/>

Answer 2

<object-to-byte-array-transformer/>     

// need to convert from an input stream to a byte array to avoid having the wire-tap close it

Adding above mentioned object-to-byte-array-transformer helped to convert input stream.
