How to publish list of pages by java(Servlet or services) ?

[Shahid_Siddiqui_04]

Let's assume I have list of path like, /content/us/en/a,  /content/us/en/b,  /content/us/en/c etc. and I want to publish these content from java 

What I have ?

List<String> allPaths = allPagesPathWhichNeedToPublish();

and want to publish all pages which is in allPaths list. What java steps I need to follow to publish path/pages one by one.

Hello @Shahid_Siddiqui_04 

We can use Replicator API to publish pages

• create a Replicator instance by using @Reference annotation.

@Reference
private Replicator replicator;

• Get a session

ResourceResolver resolver = request.getResourceResolver();
javax.jcr.Session session = resolver.adaptTo(Session.class);

• Replicate the page by looping through the list

    try {
             replicator.replicate(session, ReplicationActionType.ACTIVATE, path);
             log.info("Page activated: ", path);

    } catch (ReplicationException e) {
            log.info("Replication failed "+e.getMessage(), path);
    }

Hi @Shahid_Siddiqui_04,

Like @aanchal-sikka already described, you should use Replicator java API.

There are two options in your case:

1. Iterate through all elements in your list and run replicate method for each item.
   

   @Reference
   private Replicator replicator;
   
   // place for other code
   
   List<String> allPaths = allPagesPathWhichNeedToPublish();
   
   Session session = resourceResolver.adaptTo(Session.class);
   for(String path : allPaths) {
     try {
       replicator.replicate(session, ReplicationActionType.ACTIVATE, path, null);
     } catch (ReplicationException e) {
       e.printStackTrace();
     }
   }​

2. Use dedicate replicate method, that is consuming array of paths, in this case you do not have to iterate through the collection in your code - this option looks much cleaner and better utilizes api capabilities
   

   @Reference
   private Replicator replicator;
   
   // place for other code
   
   List<String> allPaths = allPagesPathWhichNeedToPublish();
   // converting to array as this is format accepted by replicator
   String [] paths = allPaths.toArray(new String[allPaths.size()])
   
   try {
     replicator.replicate(resourceResolver.adaptTo(Session.class), ReplicationActionType.ACTIVATE, paths, null);
   } catch (ReplicationException e) {
       e.printStackTrace();
   }

Make sure that resource resolver object you will be suing has a proper level of permission to replicate pages. You can consider to create proper service user and create resource resolver using this user, to have full control of permission set.
