No replies!!!
So far I managed to write the custom action which displays nodeuuid, username, nodetype and nodename when a user clicks on the subscribe link/action. I have used javascript based webscript to do it.
Now I need to put these values in a database.
Any idea how can I put above data into database?

Please help!!

Thanks
Sans!!

Perhaps you should say what you are trying to do rather than how.

To write to another database you will need to use Java and just use standard JDBC.

Step 4. There is a send email action. You can bolt two actions together or even better execute a sendEmail action post commit from your first action.

Hi mrogers,
I have written the subscribe action which inserts data into non alfresco tables.( like userid, nodeuuid of the subscribed document, resource name and resource type-file or folder)
If there is any change/update to the subscribed document, I want to send an email to people who have subscribed to the document.
I know there is an inbound rule which sends an email to group/person on update or delete of space or sub-space.
Can you please tell me if there is a way that I can link that rule with my requirement?

Please help!!

Thanks
Sanjay!!

Hi,
I have written a subscribe action which on click puts data in non-alfresco tables. Now I want to add My Subscriptions page the way Documents I am editing or Documents - My Favorites work.
Any Idea how can I do this?

Thanks

One way of doing this is to have a policy that fires when a node is updated. I'd add a "subscribed" aspect onto the nodes that triggers your buisness logic on create and on update. That will have to read your custom tables and send emails. Or just run a Stored Proc or a webscript or something in your external application that sends the emails.

Are you sure your architecture is correct? You could manage these subscriptions within alfresco and avoid the complications of having a dependency between systems.

Hi,
I could have used the logic of adding subscribed aspect onto the nodes.
But how am I going to scale it up for multiple users?
If two users subscribe to the same document, then how shall I reflect/show it onto the node?
Also if one of the users unsubscribes, remove the aspect but then other users will also be unsubscribed.
If there is any better approach please suggest.

Thanks
Sans

Hi,
One more quick question on the subscribe action.
I have written the subscribe action earlier with GET webscript. But the problem I found with Ajax GET request is that when you run your action in IE7, it caches your reponse and on the next click of action it doen't even submit the GET request. It simply shows the cached success or faliure message.
To work around this problem, now I am trying to convert my GET webscript into POST webscript.
But I am not sure How do I pass the nodeRef from javascript to my Java class.
Here are the snippets from different files.
subscribe-action-min.js

this.modules.actions.genericAction(
        {
           success:
           {
              message: this.msg("message.subscribe.success", file.displayName)
           },
           failure:
           {
              callback:
              {
                 fn: failureHandler,
                 scope: this
              }
           },
           webscript:
           {
         name: "subscribe/site/{site}/{container}",
              method: Alfresco.util.Ajax.POST
           },
      wait:
               {
                     message: this.msg("message.please-wait")
               },
           params:
           {
              site: this.options.siteId,
              container: this.options.containerId
           },
           config:
           {
              requestContentType: Alfresco.util.Ajax.JSON,
              dataObj:
              {
                 nodeRefs: [file.nodeRef]
              }
           }
        });‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍

SubscribeWebScript.java

public class SubscribeWebScript extends AbstractWebScript
{
……final public void execute(WebScriptRequest req, WebScriptResponse res) throws IOException
    {
        try
       {
           //userTransaction = registry.getTransactionService().getUserTransaction(); 
          authenticationService = registry.getAuthenticationService();
          String userName = authenticationService.getCurrentUserName();
          
          String rootNodeRef = req.getParameter("nodeRefs");
            
            if(rootNodeRef != null && NodeRef.isNodeRef(rootNodeRef))
            {
               nodeRef = new NodeRef(rootNodeRef);
               nodeuuid = nodeRef.getId();
            }
            
            nodeService = registry.getNodeService();
            String fileName = (String) nodeService.getProperty(nodeRef, ContentModel.PROP_NAME);
‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍

This one bombs out on (String) nodeService.getProperty(nodeRef, ContentModel.PROP_NAME);
Giving following exception.
