Enhancing OSB Integration: How to Call a Java Method to Concatenate Strings

Oracle Service Bus (OSB) offers extensive modularity, allowing for the integration of a diverse range of technologies. In this article, we will explore how to use Java methods in OSB with the objective of implementing a use case that involves concatenating two strings. We will achieve this by leveraging a Java callout, which will enhance the flexibility and functionality of our integration solution.

To get started, let's create a Java class and generate a JAR file from

package Addpkg;

public class AddInt {

    public AddInt() {

        super();

    }

    

    public static int addNum(int num1,int num2)

    {

        int num3=0;

        num3=num1+num2;

    return    num3; 

    }

}

 

Now create JAR file of the above class by following this tutorial  Generate JAR in JDEVELOPER

Once JAR file generated , now lets create Application in JDEVELOPER 

1. Go to Jdeveloper --> Create Application

Provide Application Name 

Once Application Created , Create a Project --> Service Bus Project

Provide project Name : AdditionJavaPRJ
