Hi himanshu,

Content stored in WCM is stored in a different type of repository (AVM) so you have to access it differently.

Code like this below has worked for us:


script: {
   var store="youwebapp–sandboxname";
   var contentPath ="/www/avm_webapps/ROOT/path/to/your/content";
   if (storeExists(store)) {   
      var node = avm.lookupNode(store + ":" + contentPath);
           if (node == null) {
              status.code = 404;
         status.message = store + " could not be found.";
         status.redirect = true;
         return;
           }
           model.data = node;
   }
}

function storeExists(store){
   var storeRoot = avm.lookupStore(store);
   if (storeRoot == null){
      status.code = 404;
      status.message = store + " could not be found.";
      status.redirect = true;
      return false;
   }   
   return true;
}

Hi Mark,

Thanks for the help. The code works .

I was now trying to do the same thing with java backed web scripts. But as usual, I am again stuck with which classes to use.

I was able to access a file in my web project by instantiating an object of the NodeRef class with that file's "Alfresco Node Reference" value.

But i want to access it by using the name (or the path) of the file and not its reference. My tasks include retrieving the list of the files in a particular folder(space) within the web project.

Thanks again.

Regards
Himanshu

Hi Himanshu,

Is there a particular reason why you need to use a Java backed web script? Having the script in JS and FTL gives you a lot of flexibility and we have found performance to be acceptable.

There is API documentation in the wiki - http://wiki.alfresco.com/wiki/Alfresco_Content_Management_Java_API.

I have also found it useful to look at the java code for the webscript objects, usch as ScriptNode in the SDK.
