Access Alfresco Repository using JCR and Spring APIs

[rishidx]

Hi All,

I am new to Alfresco and only want to connect to Alfresco Repository. I am following this link:
http://wiki.alfresco.com/wiki/Introducing_the_Alfresco_Java_Content_Repository_API

I am using Eclipse Galileo for development and created a Java project on it. I have included every JAR that were available in Alfresco SDK. Initially, When I ran the code

System.out.println("Start");
ApplicationContext appctx = new ClassPathXmlApplicationContext("classpath:alfresco/application-context.xml");
System.out.println(" ..Done");
‍‍‍‍‍

I got error:

<em>org.springframework.beans.factory.BeanDefinitionStoreException: IOException parsing XML document from class path resource [alfresco/application-context.xml]; nested exception is java.io.FileNotFoundException: class path resource [alfresco/application-context.xml] cannot be opened because it does not exist </em>

for which I added <Alfresco-Tomcat-Folder>/WEB-INF/classes in Projects's classpath in Eclipse and this error got resolved. But now, I am getting a new Error:

<em>org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'propertyValueCache' defined in class path resource [alfresco/cache-context.xml]: Initialization of bean failed; nested exception is org.springframework.beans.TypeMismatchException: Failed to convert property value of type 'java.lang.String' to required type 'boolean' for property 'disableSharedCache'; nested exception is java.lang.IllegalArgumentException: Invalid boolean value [${system.cache.disableImmutableSharedCaches}]

I have also tried the same with Alfresco SDK by importing them to Eclipse Galileo but still getting the same error.
I am working to remove this error from past 3-4 days. Can any one please help me out.

Thanks

which SDK example you are trying to run?
For most of the examples you need to make sure you are point to correct alf_data folder of your alfresco in alfresco-global.properties file.
If you read the instructions most of the errors you will be able to solve.
Also I hope your alfresco instance is working fine.

Thanks for reply and sorry for my late reply. Alfresco version is working fine.

What do you mean by alfresco-global.properties?

I have written a simple java application in Eclipse Helios and added all JARs available in Alfresco SDK.
then, I have added C:/Alfresco/…/alfresco/application-context.xml in Eclipse classpath as well as system's classpath.
then i have ran the below code:

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

        // Login to workspace
        // Note: Default workspace is the one used by Alfresco Web Client which contains all the Spaces
        //       and their documents
        Session session = repository.login(new SimpleCredentials("admin", "admin".toCharArray()));

        try
        {
            // Retrieve Company Home
            Node root = session.getRootNode();
            Node companyHome = root.getNode("app:company_home");
            
            // Iterator through children of Company Home
            NodeIterator iterator = companyHome.getNodes();
            while(iterator.hasNext())
            {
                Node child = iterator.nextNode();
                System.out.println(child.getName());

                PropertyIterator propIterator = child.getProperties();
                while(propIterator.hasNext())
                {
                    Property prop = propIterator.nextProperty();
                    if (!prop.getDefinition().isMultiple())
                    {
                        System.out.println(" " + prop.getName() + " = " + prop.getString());
                    }
                }
            }
        }
        finally
        {
            session.logout();
            System.exit(0);
        }

This gave the exception which i mentioned in my above post.

When will the code access global properties file??? Am i missing something???

Thanks and Regards
Rishi

If you have solved the issue, please let me know how to proceed further, even I'm facing the same error from one week
