Before you spread your confusion what are you attempting to do?

Why are you trying to lookup the ServiceRegistry in JNDI?

Please, what do i have to do ? It seems that the Problem is alreaday here:

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

robobot

after hours i made one step into the right direction…

        // Setup Spring and Transaction Service
       // ok
        ApplicationContext context = new ClassPathXmlApplicationContext("classpath*:alfresco/application-context.xml");                   
       // error
        ServiceRegistry registry = (ServiceRegistry)context.getBean(ServiceRegistry.SERVICE_REGISTRY);
‍‍‍‍‍‍‍

–> Caused by: org.springframework.beans.factory.NoSuchBeanDefinitionException: No bean named 'ServiceRegistry' is defined

System.out.println("beans: "+context.getBeanDefinitionCount()); –> 0

what do i have to do ?

thanks in advance

Have you read this WIki Page? It does roughly what you're attempting: http://wiki.alfresco.com/wiki/Java_Foundation_API

The best way to work would be to have your class managed by Spring, and use dependency injection to retrieve the ServiceRegistry bean for you. In fact, using this method, you will be able to access all of Alfrescos service classes directly.

robobot

hello,
yes i have already read this short article. once again, step by step:

1. after downloading the latest alfresco sdk i carefully added all the libs found in "SDK AlfrescoEmbedded" in its build path.
2. I added the project to the build path of "SDK JCRSamples". In this project i modified the file "custom-repository.properties" as follows:

dir.root=C:/Alfresco/alf_data‍

3. i copied the 3 files from the SDK JCRSamples Project into the alfresco extension folder

C:\Alfresco\tomcat\shared\classes\alfresco\extension‍

    custom-alfresco-shared.properties
    custom-repository-context.xml
    custom-repository.properties

4. i started my local alfresco 3.2 installation at

http://localhost:8080/alfresco‍

5. i run MixedExample from the eclipse workspace and until this point i am happy.

Now i want to use this with an remote alfresco installation.

Alfresco runs for example at http://192.168.20.144:8080/alfresco/

To keep my question simple: how can "MixedExamples" communicate with "http://192.168.20.144:8080/alfresco/" instead of "http://localhost:8080/alfresco"
