For instance ,let consider the name of the property as "XX".It is stored in the local parameter PropertyName.

If you are doing this in an Activity and don't mind using Java Steps; you can use code like this:
String PropertyName=tools.getParamValue("PropertyName");
String PropertyValue=tools.getParamValue("PropertyValue");
myStepPage.putString( PropertyName, PropertyValue );
I have a set of properties including 'title' and 'city' here; and using different parameters to my Activity the code above will set the appropriate property:
Here's the Parameter Tab for my Activity:
And the Steps - just a Page-New , the Java Steps (the code already pasted above), and a Show-Page:

For completeness here's the Pages & Classes tab, change this for your class structure of course:
And when I run this with the Parameter set to 'Title' :
The Show-Page confirms the '.Title' property is set:
<pagedata>
<pxObjClass>GCS-GCSApp-Work</pxObjClass>
<Title>Hello</Title>
<pzStatus>valid</pzStatus>
</pagedata>
If I run it again with 'PropertyName' set to 'City', it changes to this:
<pagedata>
<pxObjClass>GCS-GCSApp-Work</pxObjClass>
<City>Hello</City>
<pzStatus>valid</pzStatus>
</pagedata>
TIP: It is informative to use the 'Show Java' option on the 'Actions' Button on the Activity Screen in the Designer Studio - I used this to remind myself how to get at the API needed to fetch stuff from the parameters page for instance : just create a standard 'Property-Set' step which references 'Param.yourparam' , save the Activity and then 'View Java'.
Also: The Engine Java API is available from the Designer Studio from the Resources > Engine API menu. (on 721, other versions have a 'help' menu).
Useful Engine Classes to look at to start with:
PublicAPI (this is what 'tools' is an instance of, in automatic code)
ClipboardPage (this is what 'myStepPage' is an instance of , in automatic code).
ClipboardProperty
Hope this helps,

It would best to push the property value to the clipboard so that it would be easier to access.
Have you tried that already?
