A number of JavaScript root objects are available when you are implementing a controller for a Repo Web Script, such ascompanyhome andpeople. Sometimes you might have custom Java code that you want to call from JavaScript controllers, this is possible by adding custom JavaScript root objects.
Architecture Information:Platform Architecture
It is possible to create and add custom script APIs implemented in Java and accessible as root objects in JavaScript. This provides an integration point for Content Services extensions to provide custom JavaScript APIs where appropriate.
In order to implement a custom JavaScript API it is recommended that you develop a POJO (Plain Old Java Object) that extends the base classorg.alfresco.repo.processor.BaseProcessorExtension. Thepublic methods of your class will be those that will be accessible from JavaScript.
Let’s implement a custom root object that can print text to the log (i.e.tomcat/logs/catalina.out):
package org.alfresco.training.jscript;import org.alfresco.repo.processor.BaseProcessorExtension;public class CustomProcessorExtension extends BaseProcessorExtension { public void log2StdOut(String text) { System.out.println(text); }}This class needs to be defined as a Spring Bean with parent set tobaseJavaScriptExtension:
<bean parent="baseJavaScriptExtension"> <property name="extensionName" value="custom" /></bean>TheextensionName property is used to configure what root object name you want to use in the JavaScript controllers.
The newcustom root object can now be used in the JavaScript controller as follows:
custom.log2StdOut("Hello World!");JavaScript root object implementations does not lend themselves very well to be manually installed in an application server.
See Deployment SDK Project instead.
