[opencms-dev] How to check existance of a resource

[Farnaz Fotrousi]

Hi,
In CMS workplace, I have created some pages with links in. These links refer to pages which created before in CMS Workplace. 
I would like to check existance of these resources dynamically. I mean if resource for the url exists, creates link otherwise doesn't create .
Would you please help me how I can check existance of the resourece? Is there any API which can help me?
 
Regards,
Farnaz Fotrousi
