Email csv file from local machine using cMail component throws Null Pointer

[Anonymous]

Hi 

I am trying to send the CSV file from my local machine via email using cMail component. The code in my cProcessor is below is :

import java.io.File;

String path = "C:\\Users\\Talend\\Downloads\\Report_20190226.csv";
exchange.getIn().addAttachment(path.substring(path.lastIndexOf("\\")+1), new javax.activation.DataHandler(new javax.activation.FileDataSource(path)));
exchange.getIn().setBody("Hello");
System.out.println(path);

but it gives the following exception: 

java.lang.NullPointerException

Please help me where my exchange is getting null.
The flow is shown in the image attached.

Thanks

Hi,

   Before doing the processing, could you please print and verify whether the file names are parsed in the right way?

   Please assign the data to a variable and print the steps like last index parse. It should give you a clue.
