Answer 1

You should use the setPropertyActionListener with action . Listeners are called before your action is invoked. It seems like the setPropertyActionListener is getting called after actionListener.
Change actionListener="#{tableBean.printView}" to action="#{tableBean.printView}"
and method to
public void printView() {
try{
System.out.print("Selected Person "+getSelectedJob.getName());
}catch(Exception e){
}
}
see this for better understanding of what to use ,

Answer 2

You can use datatable selection like this
<p:dataList value="#{tableBean.getList()}" selection="#{tableBean.selectedJob}" var="job" id="cars"
paginator="true" rows="5" effectSpeed="fast"
paginatorTemplate="{PreviousPageLink} {CurrentPageReport} {NextPageLink} {RowsPerPageDropdown}"
rowsPerPageTemplate="5" type="none">
