Coding Structure for Java Callout Main Class

Update the code as per the need in the try block
import com.apigee.flow.execution.ExecutionContext;
import com.apigee.flow.execution.ExecutionResult;
import com.apigee.flow.execution.spi.Execution;
import com.apigee.flow.message.MessageContext;
//@Component
public class App implements Execution{
public ExecutionResult execute(MessageContext messageContext, ExecutionContext executionContext) {
try {
        messageContext.setVariable("foo", "Heloo");
        return ExecutionResult.SUCCESS;
    } 
catch (Exception e) {
        return ExecutionResult.ABORT;

Build or Generate Project JAR file

• Right click on project
• Select Run as > Maven Clean
• Select Run as > Maven Install
• Open your project Location > Target > ProjectName+-jar-with-dependencies.jar  

This will be the jar which needs to be imported on Apigee as a jar resource

Note the class name in the javacallout should be the class qualified name

for example : right click on /src/main/java copy qualifier name /testing-app/src/main/java/JavaApigee/test_app/AthenaDataFetcher.java here classname would be JavaApigee.test_app.AthenaDataFetcher
