NullPointer@uploading a file from local system to alfresco

Hello,Below is the code I have written to upload a file from my local system to Alfresco repository..####################################################package org.alfresco.sample;import javax.jcr.Node;import javax.jcr.Repository;import javax.jcr.RepositoryException;import javax.jcr.Session;import

The following statement will cause problems:
new FileFolderServiceImpl();

There's lots of initialisation missing here. You need to either grab the FileFolderService bean from spring. Or access it through the repository's service registry.

Thanks!

How we can get access to FileFolderServiceImpl through "service registry"?

Either you use the service registrys getter method:

org.alfresco.service.ServiceRegistry.getFileFolderService();‍

Or you inject it in your spring bean configuration, for example

<bean id="yourBean" class="org.xyz.yourBean">
      <property name="fileFolderService">
         <ref bean="FileFolderService" />
      </property>
</bean>‍‍‍‍‍

in a *-context.xml file.

Which you decide to use depends on the context you are in.

Thanks…

I modified my code as per your suggestion but got Null pointer @ getFileFolderService()–> getService(). I debugged but found nothing relevent. Can you please suggest?

Same problem, but this time you have an uninitialised ServiceRegistry.
You need to get the "ServiceRegistry" from spring not create it yourself.

Your "repository" variable has a getServiceRegistry() method. Try to use that instead.

Sorry …. plz ignore fileoutputstream logic that is just for testing only…

i have another doubt .. is it model for file/folder needed to run this java application. I have custom-repository.properties and custom-repository-context.xml if any other things needed plz tell me in detail

Thank in advance

Re: NullPointer@uploading a file from local system to alfresco

Hello All

I finally got remedy for this issue 🙂 Thanks for your suggestions and helps!

sangi,

For your problem; suggess you do the following modifications:

1) Change the way you are getting access to company home in Noderef:
ServiceRegistry serviceRegistry = (ServiceRegistry) context.getBean("ServiceRegistry");

// Get root node for default store: SpacesStore
NodeRef rootNodeRef = serviceRegistry.getNodeService().getRootNode(new StoreRef("workspace://SpacesStore"));
// Find children of root node with association name "app:company_home" (must be one)

List<NodeRef> nodes = (List<NodeRef>) serviceRegistry.getSearchService().selectNodes(rootNodeRef, "app:company_home", null,serviceRegistry.getNamespaceService(), false);

if (nodes.size() == 0) {
throw new AlfrescoRuntimeException("Unable to find store path: app:company_home");
}

NodeRef companyHome = nodes.get(0);

2) Get FileFolderService from spring:
FileFolderService fileFolderService = (FileFolderService) context.getBean("fileFolderService");

And then use it like below:

FileInfo fileinfo = fileFolderService.create(companyHome, file.getName(), ContentModel.TYPE_CONTENT);

3) Get ContentService also from spring:
ContentService contentService = (ContentService) context.getBean("contentService");

regards-
Amit.

Anything i missed ? ? ?

LOGIC :

   File file=new File("/home/chander/test.txt");
           System.out.println("Inside tcheckin-2 :");
           ServiceRegistry serviceRegistry = (ServiceRegistry) context.getBean("ServiceRegistry");
           NodeRef rootNodeRef = serviceRegistry.getNodeService().getRootNode(new StoreRef("workspace://SpacesStore"));
        // Find children of root node with association name "app:company_home" (must be one)
           System.out.println("rootNodeRef :"+rootNodeRef.getId());
        List<NodeRef> nodes = (List<NodeRef>) serviceRegistry.getSearchService().selectNodes(rootNodeRef, "app:company_home", null,serviceRegistry.getNamespaceService(), false);

        if (nodes.size() == 0) {
        throw new AlfrescoRuntimeException("Unable to find store path: app:company_home");
        }
System.out.println("nodes size :"+nodes.size());
        NodeRef companyHome = nodes.get(0);

        System.out.println("companyHome :"+companyHome);
        FileFolderService fileFolderService = (FileFolderService) context.getBean("fileFolderService");
           System.out.println("file.getName() : "+file.getName());
           FileInfo fileinfo = fileFolderService.create(companyHome, file.getName(), ContentModel.TYPE_CONTENT);
           System.out.println("fileinfo.getName() : "+fileinfo.getName());
           NodeRef fileRef = fileinfo.getNodeRef();
           System.out.println(" fileRef.getId() :"+fileRef.getId());
           InputStream contentStream=new BufferedInputStream(new FileInputStream(file));
           ContentService contentService = (ContentService) context.getBean("contentService");
           System.out.println("Inside tcheckin-5 :"+contentService.toString());
           ContentWriter writer = contentService.getWriter(fileRef, ContentModel.PROP_CONTENT, true);
           String contentUrl = writer.getContentUrl();
            System.out.println("contentUrl :"+contentUrl);

           writer.putContent(contentStream);
           }

Hi Sangi

Save the session object at the end (after writer.putContent(contentStream);
###################
session.save();
###################

You will then be able to see your uploded file in alfresco ui(console) :wink:

regards
Amit

This is how i am creating Session :

context = new ClassPathXmlApplicationContext("classpath:alfresco/application-context.xml");
       Repository repository = (Repository)context.getBean("JCR.Repository");
       // /home/chander/apps/eswar/alfrescoLabs3b/tomcat/webapps/alfresco/WEB-INF/classes/alfresco
       // login to workspace (here we rely on the default workspace defined by JCR.Repository bean)
      Session session = repository.login(new SimpleCredentials("admin", "admin".toCharArray()));
      System.out.println("Session Id "+session.getUserID());

Hi everybody,

Do you have any ideas on how we can "programatically" do versioning of these uploaded files? If so, please share…

Thanks in advance
Amit.
