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.

i am using the web-config-custom.xml for refrences of nodeRef etc. i am able to get the path,name and id of the node which i select or browse(the particular node i am interested in).now i want to get the content.g.text or picture inside. how i can do that?

thanks for the quick reply

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!!!!

mrogers

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");

tejaswini

good morning.,
thnks…
   so how we can get the ServceRegistry?
if its available then how to access? and if its present then whn i try———–>

System.out.println("service regisrt="+serviceregistry);
why it gives null???

   will u pls tell me how to do that?
   its very urgent….

goodday!!!

tejaswini

good morning.,
i am still stuck on the same problem and i dont know how to move further. let me know the way by which i can achieve that.
pls hurry up ….
goodday!!!!

cheffilet

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

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

mrogers

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

flopez

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.

mrogers

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.

waynejiang

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();
    }
}‍‍‍‍‍‍‍‍‍‍‍‍‍‍
