Hi every one

How to pass the Datatable value into backing bean;

I using this code, but i con't get that value in backing bean;
//This is XHTML Code

Datatable Value is= "#{sysCountryList.resultList}"

<s:link  value="Click Me" action="#{report.ExportToPdf()}"  target="_blank">
//Here i pass that datatable value;
<f:param name="DATATABLEVALUE" value="#{sysCountryList.resultList}"/>
</s:link>


//This is my bean class
//Here i get that datatable value
public void setReportName(String DATATABLEVALUE)
{
this._data=DATATABLEVALUE;
}
public String getReportName()
{
return this._data;
}

But the datatable value is null,

How can i get the datatable value in my backingbean,

Anybody help me:

Thanks
