Thanks @Rohit Reddy for your response.​ .

But i am facing issue while implementing solution this into Dataweave.

In Mule 3 use the enricher. Here is an example that wraps the json to object in an enricher and extracts a value into a variable and leaves the payload intact:

<flow name="test">
		<poll frequency="10000" doc:name="Poll">
			<logger level="ERROR" message="started" doc:name="Logger" />
		</poll>
 
		<set-payload doc:name="Set Payload"
			value="{&quot;myField&quot;:&quot;myValue&quot;}" />
		<enricher target="#[flowVars.myFieldVar]">
			<processor-chain>
				<json:json-to-object-transformer
					returnClass="java.util.HashMap" />
				<set-payload value="#[payload.myField]" />
			</processor-chain>
		</enricher>
 
		<choice>
			<when expression="#[flowVars.myFieldVar =='myValue']">
				<logger level="INFO" message="myField is equal to myValue" />
			</when>
			<otherwise>
				<logger level="INFO" message="meh" />
			</otherwise>
		</choice>
 
		<logger level="INFO" message="Payload is still original payload #payload" />
 
 
	</flow>

LoggerMessageProcessor: myField is equal to myValue
LoggerMessageProcessor: Payload is still original payload {"myField":"myValue"}

 Note you can also save multiple targets at once for setting multiple variables in one enricher. But the syntax is slightly different. Google the docs to find that syntax.

Also note if you have multiple processors in your enricher they need to be wrapped in a processor-chain, like in the example.

Hi Shekh,

Thank you for your reply.

Tried the link above. But no luck. Still getting the same issue for the type .xlsx. Able to receive the attachment with 412 bytes - file size. When I save this in my local (file size is zero) and tried to open, getting the below error message. Anything need to check from smtp side? No clue on what I am missing here.

<set-attachment attachmentName="#flowVars.fileNamePattern.xlsx" value="#payload" contentType="text/html" doc:name="Attach Excel File"/>
