SAP CPI - Groovy script to split a string and make an array list

[#1]

Hi guys,

I am writing the below code to split the string(separated by comma) into a list array.

I am giving multiple values to "source value" in content modifier.

Code:

import com.sap.gateway.ip.core.customdev.util.Message;

import java.util.HashMap;

import java.util.regex.*;

import groovy.xml.*;

def Message processData(Message message) {

def headers = message.getHeaders();

def rows;

def properties = message.getProperties();

def credentials = properties.get("UserList");

List<String> myList = Arrays.asList(credentials.split(","));

for(i=0;i < myList.size();i++)

{

rows = rows + (myList[i]+"\n");

}

// rows = rows.replace("null","");

message.setBody(rows)

return message;

}

But when I run this, I was able to get the below output.

I am getting a null at the beginning, I can simply replace it. I also tries to assign null value to my variable"rows". But still I am getting the same output. I want to know what is wrong with my groovy code.

Thank you!

Hello Veena,

Since you already created List, you can check and remove null values first, then continue with your logic.

list.removeAll([null])
