Java-backed web scripts are web scripts whose controller implementation is written in Java, rather than JavaScript.
Java-backed web scripts are useful when you want to:
- Access Content Services not available by using the JavaScript API
- Interact with systems whose only API is exposed by using Java
- Override how responses are rendered, such as to stream large content
- Ensure that performance is absolutely critical
Unlike scripted web scripts, Java-backed web scripts require more tooling for their development as you must compile the Java source code, package, and deploy to the Content Services server.
A Java-backed web script is constructed like a scripted web script, except that a Java class replaces the controller script. It still has the same intent of encapsulating the behavior of the web script and producing a model for subsequent rendering by a response template. Content Services is aware of the Java class through Spring Framework configuration, which identifies the Java class as being the behavior for the web script. All other components are exactly the same as those for scripted web scripts.
