            <apex:tab id="tab1" name="tab1" >                <apex:detail/>              </apex:tab>               <apex:tab id="tab2" name="tab2" >                 <apex:include pagename="page2" />                 </apex:tab>

`

you need wrap <apex:tab> components in <apex:tabpanel> component, so:

<apex:tabpanel selectedtab="tab1">   <apex:tab name="tab1">     <!-- put tab 1 content here -->   </apex:tab>   <apex:tab name="tab2">     <!-- put tab2 content here -->   </apex:tab>   <!-- etc --> </apex:tabpanel>
