Not able to delete a subscription using the RAM 7511 java api

In the for loop, remove the asset.addSubscription(subscription); statement. Setting the action to RAMAction.DELETE is the only thing required. Also it's not necessary to update the asset inside the loop. If you have multiple subscriptions, it gets expensive to update the asset everytime.

Just a suggestion but in the println you could include the user as well.

Here's the code I executed against our 7.5.1.1 development test server:

    public static RAMSession session = null;

    public static void main(String[] args) {
        session = new RAMSession("http://<ram_server_url>/", "admin_userid", "admin_password");
        RAMAsset asset = session.getAsset(new AssetIdentification("asset_guid", "asset_version"));
        RAMSubscription[] subscriptions = asset.getSubscriptions();

        for (RAMSubscription subscription : subscriptions) {
            subscription.setAction(RAMAction.DELETE);
            System.out.println("Deleted the subscription for user" + subscription.getUser());
        }
        session.put(asset, new RAMStatusMonitor());
    }
