How to access property under jcr:content of page from a component inside a parsys of the page

Hi,

I have a parsys component in my page inside this parsys i have dragged and dropped a custom component into the parsys. Now i had customized the page property dialog.Now when i add value to the page dialog this value gets stored under /content/page/jcr:content/customprop .Now i want to access this custom property value inside my custom dragged component jsp inside parsys.

Within Same component i know we can access properties like          <%=properties.get("sling:resourceType", "default title")%>

Whereas how do i access page property inside the component.

Please let me know.

Regards,

Raja
