Basic Script Example for Beginners

The main entry point is function processData by default. You can change it in the UI.

This function gets Message object defined in and returns it back.

Message object contains:

It also supports SOAP headers & attachments but for clarity, we will look into that later.

Changing body

In this basic example we don't modify XML using XML libraries. We just treat it as a string.

message.getBody function can return different Java types. There is a related blog post in SAP Community.

Changing headers & properties

They provide similar functions. You can get a Java Map object by calling message.getHeaders() and message.getProperties().

You can use functions on the message object to set new headers, or modify existing ones.


Try it on Groovy IDE
import java.util.HashMap;

def Message processData(Message message) {
    println "You can print and see the result in the console!"
    def body = message.getBody(String);
    message.setBody(body + "Body is modified");
    def map = message.getHeaders();
    def value = map.get("oldHeader");
    println "oldHeader value: " +value
    message.setHeader("oldHeader", value + " World!");
    message.setHeader("newHeader", "newHeader value");

    def mapProperties = message.getProperties();
    def valueProperty = mapProperties.get("oldProperty");
    message.setProperty("oldProperty", valueProperty + "modified");
    message.setProperty("newProperty", "newProperty value");
    return message;
