Integrating SaaS with external applications using JCS-SX

Venkatesh Yadavalli-OracleJun 29 2016 — edited Jul 1 2016

Overview

An enterprise wants to assign a Credit Health Score to every account/opportunity. This score ranges from 1 to 10 and is calculated based on a complex logic involving data from several internal and external systems. The enterprise has built a bespoke web application developed and maintained by a development team within the enterprise that

  • Exposes the Credit health score calculation logic as a web service and is deployed in JCS-SX
  • Is deployed on Oracle Cloud Services: Java Cloud Service SaaS Extension
  • Is used to calculate the credit health score of every account/opportunity

This short screen cast provides a brief functional and technical overview of this solution.

Figure 3: Integrate SaaS applications with external systems

Solution Approach

A sales manager logs into Oracle Sales Cloud to view the details of an account. When the user selects an account, on the default account view page, he finds a new custom field called “Credit Health Score”. The value of this custom field is fetched by invoking the Credit Health Score web service deployed in JCS-SX. Please refer to this sample application on oracle cloud developer portal for more detailed explanation about building this extension.

The pre-configured security and trust between PaaS (JCS-SX) and SaaS (Sales Cloud) enables Sales Cloud to make secure web service call to the bespoke application deployed in JCS-SX without any additional security setup. Please refer to this blog for more details on securing web service interactions between Oracle Sales Cloud and JCS-SX.

JRE may not be enabled in your browser. Check whether it is enabled or not?

You can verify that from 'Tools -> Internet Options -> Advanced -> Java (sun)'

I'm having trouble deciphering that message as well. ..Mostly because you did not copy/paste it.

The JVM being used by the browser is earlier than the version of javac you compiled the applet with.

So update the browser's JVM or use the -target switch of javac.

If you get a message you can't 'decipher', post it. Just saying you can't decipher it only wastes time.

I'm running Java SE 7, which should be the latest version of Java available. Does this mean I need to update my compiler?

Sorry that I keep asking these questions but I want to make sure my applets will run properly in the future.

No, it means that your browser isn't running Java 7, but has an older plugin.

Then maybe use the target flag when compiling so it's compatible with 1.5. Version 1.6 tops. Unless you really need to use all the new features.
