Can MULE post XML-file over HTTP from local directory? - http

Question

I need to transfer XML-files over HTTP POST. Can Mule be configured to do this. I've been trying with an easy flow, inbound file --> outound HTTP but it's not working. Does anyone have any experience of this?
<flow name="rpg_uploadFlow1" doc:name="rpg_uploadFlow1">
<file:inbound-endpoint path="C:\Users\Claes\Documents\CD-utveckling\paper-rpg\OUT" moveToDirectory="C:\Users\Claes\Documents\CD-utveckling\paper-rpg\sent" responseTimeout="10000" mimeType="text/xml" doc:name="File"/>
<http:outbound-endpoint exchange-pattern="one-way" host="http://XXXXXXXXXXX.ashx?SystemName=XXXX&UserName=XXXX&PassWord=XXXXX" port="80" disableTransportTransformer="true" doc:name="HTTP"/>
</flow>
Error;

Answer 1

I have had trouble in some spots with the file endpoint because it passes along a filereader as the payload instead of the actual text. Try adding a file-to-string converter:
<flow name="rpg_uploadFlow1" doc:name="rpg_uploadFlow1">
<file:inbound-endpoint path="C:\Users\Claes\Documents\CD-utveckling\paper-rpg\OUT" moveToDirectory="C:\Users\Claes\Documents\CD-utveckling\paper-rpg\sent" responseTimeout="10000" mimeType="text/xml" doc:name="File"/>
<file:file-to-string-transformer doc:name="File to String"/>
<http:outbound-endpoint exchange-pattern="one-way" host="http://XXXXXXXXXXX.ashx?SystemName=XXXX&UserName=XXXX&PassWord=XXXXX" port="80" disableTransportTransformer="true" doc:name="HTTP"/>
</flow>

Answer 2

You can use a mule byte array to string transformer to make your request as string and then post it to your http outbound.
<flow name="rpg_uploadFlow1" doc:name="rpg_uploadFlow1">
<file:inbound-endpoint path="C:\Users\Claes\Documents\CD-utveckling\paper-rpg\OUT" moveToDirectory="C:\Users\Claes\Documents\CD-utveckling\paper-rpg\sent" responseTimeout="10000" mimeType="text/xml" doc:name="File"/>
<byte-array-to-string-transformer></byte-array-to-string-transformer>
.....
Coming to your error. I gues it is not related to mule tags and endpoints. It is something in accessing the url you are trying.
See the below post for the issue related to UnknownHostException.
java.net.UnknownHostException when accessing a URL

Answer 3

Try this:
You can use a mule byte array to string transformer to make your requested File as string and then use SetPayload or Attachment Connector and post it to your http outbound.
