ServiceRegistry

tejaswini — Tue, 09 Feb 2010 09:27:56 GMT

i am trying to read a node using contentReader. for that i should have a ServiceRegistry. what i am doing is getting that with help of injection in .xml but after that i am getting exceptions. will anybody help me out? thanks in advance.

Not without details of the exception. Your code would also help people to answer you.

The service registry is a hack for the times when you can't use injection, so you should not need it.

good morning.,
   i am doing something like this—>
       class WebSettingBean implements Serializable
       {
         protected ServiceRegistry serviceRegistry;

   //getter and setter methods
        public void setActive(ActionEvent event) {

       //some actions and System.out.println()s
       }
     whn i run this code it works fine and i get the output on console
     now i am adding two statements to evaluate() as
           ApplicationContext cxt = new ClassPathXmlApplicationContext("classpath:alfresco/application-context.xml");
           ServiceRegistry serviceRegistry=(ServiceRegistry)cxt.getBean("serviceRegistry");

the bean has configured in someco-action-context.xml as

<bean id="name" class="com.someco.bean.WebSettingsBean">
   <property name="serviceRegistry">
      <ref bean="ServiceRegistry"/>
   </property>
   <property name="repository">
      <ref bean="JCR.Repository"/>
   </property>
</bean>

the web-client-config-custom conatains

<action id="web_enable">
            <permissions>
               <!– each permission can be an Allow or Deny check –>
               <permission allow="true">Write</permission>
            </permissions>
            <!– new code –>
            <evaluator>com.someco.action.evaluator.WebEnableEvaluator</evaluator>

            <label-id>enableWeb</label-id>
            <image>/images/icons/create_website.gif</image>
             <action-listener>#{WebSettingsBean.setActive}</action-listener>

            <action>dialog:executeScript</action>
            <action-listener>#{BrowseBean.setupSpaceAction}</action-listener>


            <params>
               <param name="id">#{actionContext.id}</param>
               <param name="active">true</param>
            </params>
         </action>

i am getting exceptions as

   hope this will give u an idea of my problem
goodday!!!!

Re: ServiceRegistry

mrogers — Wed, 10 Feb 2010 22:12:31 GMT

You should not need to call the following code since the context is already loaded.

ApplicationContext cxt = new ClassPathXmlApplicationContext("classpath:alfresco/application-context.xml");
ServiceRegistry serviceRegistry=(ServiceRegistry)cxt.getBean("serviceRegistry");

This is a realy bad idea on starting a separatly managed Beancontext!

This looks like using Alfresco Explorer JSF Client. This means you´re able to use FacesContext instance which is bound to the local thread!

ServiceRegistry serviceRegistry = org.alfresco.web.bean.repository.Repository.getServiceRegistry(FacesContext.getCurrentInstance());

bwagner — Fri, 16 Apr 2010 08:54:46 GMT

any hint how to do this for JCR Repository? I tried the wiki example


final ApplicationContext context = new ClassPathXmlApplicationContext("classpath:alfresco/application-context.xml");
final Repository repository = (Repository) context.getBean("JCR.Repository");
‍‍‍‍

which leads to errors

Hi there,

I'm having trouble importing the service registry for a java backed (share) webscript that implements ApplicationContextAware:

import org.alfresco.service.ServiceRegistry;

What jar is it located, or did it change for the 3.4b version of alfresco community, can't resolve 'ServiceRegistry' which I intend to use for content/workflow services

Anyone can please give me a clue?

Thank you in advance

Re: ServiceRegistry

mrogers — Fri, 25 Feb 2011 13:33:17 GMT

If you are using a "Java Backed WebScript" then you don't need it, use spring injection instead.

Its in the Repository Project.

Hello mrogers, thanks for answering! I'll take a look at that

Re: ServiceRegistry

flopez — Mon, 28 Feb 2011 15:28:49 GMT

Hello again, indeed I've tried to inyect it but it seems I'm missing something or I'm just misunderstanding it, here is a simplified version of what I'm trying to do:

I have my java class TestWebScript.java which Im making application context aware so that I can inject the context and get from it ServiceRegistry like this:



import org.springframework.context.ApplicationContext;
import org.springframework.context.ApplicationContextAware;

import org.alfresco.service.ServiceRegistry;

public class TestWebScript extends AbstractWebScript implements ApplicationContextAware {

    private ServiceRegistry serviceRegistry;
    private ApplicationContext applicationContext;  
   
     @Override
    public void setApplicationContext(ApplicationContext arg0) throws BeansException {
       this.applicationContext = applicationContext;   
    }

    public void execute(WebScriptRequest req, WebScriptResponse res){

       this.serviceRegistry=(ServiceRegistry)applicationContext.getBean("serviceRegistry");   
       // serviceRegistry.getAnyServices and use them
    }
   
}
‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍

To make this class compile in share, I had to add the 'alfresco-repository-3.4.c.jar' from the repository project as you suggested so that it recognizes the
import org.alfresco.service.ServiceRegistry;

I include the definition for my bean in the slingshot-application-context.xml in share, like this:

   <bean id="webscript.org.alfresco.components.package.testwebscript.get" 
      class="package.TestWebScript "
      parent="webscript">
        <property name="serviceRegistry" ref="ServiceRegistry" />
   </bean>‍‍‍‍‍

Like suggested in most other places, but context can't bes initializad because share don't seem to resolve/find the 'ServiceRegistry' bean the only one available is referenced as: <property name="serviceRegistry" ref="webframework.service.registry" /> But that's not the one… what am I missing?

Thank you in advance.

Re: ServiceRegistry

mrogers — Mon, 28 Feb 2011 16:32:36 GMT

Ah…. You can't access the Service Registry or any of the Java API's from Share What you have to do is call one of Alfresco's remote imterfaces.

Re: ServiceRegistry

waynejiang — Wed, 08 Feb 2012 02:43:42 GMT

If you need get the current user in java backed webscript frm Share. Code as below,

import org.springframework.extensions.surf.RequestContext;
import org.springframework.extensions.surf.support.ThreadLocalRequestContext;
import org.springframework.extensions.webscripts.AbstractWebScript;
import org.springframework.extensions.webscripts.WebScriptRequest;
import org.springframework.extensions.webscripts.WebScriptResponse;
import org.springframework.extensions.webscripts.connector.User;

public class DemoAction extends AbstractWebScript {
    @Override
    public void execute(WebScriptRequest request, WebScriptResponse response) {
        RequestContext context = ThreadLocalRequestContext.getRequestContext();
        User user = context.getUser();
    }
}‍‍‍‍‍‍‍‍‍‍‍‍‍‍
