Question

I am trying to create a datatable using JSF primefaces. I know there is a tag called datatable but am really unclear on how to use it. As in I can’t picture its relationship with the bean. My table should be ID, Status, Details. Any idea how to do this or where to go for it?
oh forgot to add that the number of rows will depend on returned from resultset from database.
Thanks,

You need to convert your result set into the List of entity (for example List<Book> ) and then set it as Bean ‘s property,

and use following code in XHTML

 <p:dataTable id="books" value="#{yourBean.books}" var="book">  

    <p:column>  
        <f:facet name="header">  
            <h:outputText value="Title" />  
        </f:facet>  
        <h:outputText value="#{book.title}" />  
    </p:column>  

    <p:column>  
        <f:facet name="header">  
            <h:outputText value="Author" />  
        </f:facet>  
        <h:outputText value="#{book.author}" />  
    </p:column>  

</p:dataTable>
