how to access the sibling pages of a page if I only have the Path of page?

[rahul234dabas]

I want to get sibling pages of a particular page  of which I only have url

I know how to get sibling pages of the current page, I used Page class to fetch the sibling pages but 

I want to know if I can do it for other pages if I have the URL.

Please help me to find out if it's possible and if so how.

If you are able to fetch siblings of current page, then same logic you can use for other pages as well as you already have a path. You can use ResourceResolver to get Page resource and use same logic.

resourceResolver.getResource(PAGE_PATH).adaptTo(Page.class);

To get siblings, you can just get Parent of a Page and then iterate child nodes as explained here

resourceResolver.getResource(PAGE_PATH).adaptTo(Page.class);

Please confirm if resourceResolver is coming null or resourceResolver.getResource(PAGE_PATH)?

Sample code from default project structure. 

@Model(adaptables = Resource.class)
public class HelloWorldModel {

    @SlingObject
    private ResourceResolver resourceResolver;

    @PostConstruct
    protected void init() {
       Resource res =  resourceResolver.getResource("/content/we-retail");
    }
}

Once you get the Page object you can use this to get all the siblings of that page.

page.getParent().listChildren();

I don't have page object , I only have page path

[Sachin_Arora_]

As explained above, you can get Page object using this code.

resourceResolver.getResource(PAGE_PATH).adaptTo(Page.class);
