Having problems creating a new kind of Webscript

[oluwasegzy]

I am trying to create custom tag in my webscript description file the would represent an extension to the description URI.

I am using the example java code in the Alfresco Professional

Chapter 11; Creating a new Kind of Web Script

NodeWebScript.java and NodeWebScriptExtension.java

after deploying my java classes and the nodewebscript-context.xml below shown

<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE beans PUBLIC '-//SPRING//DTD BEAN 2.0//EN' 'http://www.springframework.org/dtd/spring-beans-2.0.dtd'>
<beans>
<bean id="webscript.org.example.nodewebscript"
class="org.example.NodeWebScript" parent="webscript" scope="prototype">
<property name="repository" ref="repositoryHelper"/>
</bean>
<bean id="webscriptdesc.org.example.nodewebscript"
class="org.example.NodeWebScriptExtension"/>
</beans>

Alfresco Application does not start but throws the following exception

Exception

I dont seems to understand where this exception is coming from

You can probably ignore that error,  since its due to a problem shutting down alfresco.    The cause of Your problem is probably higher up.

I just took a closer look at all the Stack Trace and then i found this line which i think is the actual case of the problem am having

Am not having this exception at shutdown, am having it at launching the Alfresco Application

   at org.apache.catalina.startup.Bootstrap.main(Bootstrap.java:414)

O.K.   That's a straightforward problem with your code, you need to make sure your class has a public setRepository method.

My code has a setRepository public method, the listing of my code is show below


package org.example;
import java.io.Serializable;
import java.util.HashMap;
import java.util.Map;
import org.alfresco.repo.model.Repository;
import org.alfresco.service.cmr.repository.NodeRef;
import org.springframework.extensions.webscripts.*;
//import org.alfresco.web.scripts.Cache;
//import org.alfresco.web.scripts.DeclarativeWebScript;
//import org.alfresco.web.scripts.Status;
//import org.alfresco.web.scripts.WebScriptException;
//import org.alfresco.web.scripts.WebScriptRequest;
public class NodeWebScript extends DeclarativeWebScript{
   private Repository repository;
   public void setRepository(Repository repository)
   {
   this.repository = repository;
   }
   protected Map<String, Object> executeImpl(WebScriptRequest req,
   Status status, Cache cache)
   {
   // extract node path from description extensions
   Map<String, Serializable> extensions =
   getDescription().getExtensions();
   String path = (String)extensions.get("path");
   // search for folder within Alfresco content repository
   String nodePath = "workspace/SpacesStore/" + path;
   NodeRef node = repository.findNodeRef("path", nodePath.split("/"));
   // validate that node has been found
   if (node == null)
   {
   throw new WebScriptException(Status.STATUS_NOT_FOUND,
   "Path " + path + " not found");
   }
   // construct model for response template to render
   Map<String, Object> model = new HashMap<String, Object>();
   model.put("node", node);
   return model;
   }

}

what could be wrong with it
