How can I get the list of pages in a folder?

Hi,

I want to have the list of pages of news in news folder. I want to return the title & date of created time sorted one.

I need a limit number in order to return those # of news pages information. I have a dialog which has 2 field: Path of news & limit number;

    String parentPage = properties.get("parentPage", currentPage.getPath());
    // this one shows me the path parentPage: /content/ci/news

   (I am not sure how to write this part: TagManager tagM = resourceResolver.adaptTo(TagManager.class); )?!

   I tried with pagemanager which wasn't success.

Now, how should I return the list of pages in this path?

Thanks,

Bahareh
