<tag>
<name>pager</name>
<tagclass>org.apache.struts.taglib.logic.PagerTag</tagclass>
<bodycontent>JSP</bodycontent>

Sample of JSP page with pager tag -
<bean:define id="offset" name="newsSlide" property="offset"
type="java.lang.Integer"/>
<bean:define id="pageSize" name="newsSlide" property="slideLength"
type="java.lang.Integer"/>
<bean:define id="totalSize" name="newsSlide" property="totalLength"
type="java.lang.Integer"/>
<logicext:pager id="pager" resultId="pagerPanel"
show="false" offset="offset" pageSize="pageSize"
totalSize="totalSize">
<logic:greaterThan name="pager" property="pagesTotal" value="1">
<table>
<tr>
<td>
<logic:equal value="true" property="hasPrev" name="pager">
<html:link property="prev.link" name="pager" forward="news">Prev</html:link>
</logic:equal>
<logic:equal value="false" property="hasPrev" name="pager">Prev</logic:equal>
</td>
<logic:iterate property="linksIterator" name="pager" id="pagerItem">
<td>
<logic:equal value="false" property="isCurrent" name="pagerItem">
<html:link property="link" name="pagerItem" forward="news">
<bean:write property="label" name="pagerItem"/>
</html:link>
</logic:equal>
<logic:equal value="true" property="isCurrent" name="pagerItem">
<bean:write property="label" name="pagerItem"/>
</logic:equal>
</td>
</logic:iterate>
<td>
<logic:equal value="true" property="hasNext" name="pager">
<html:link property="next.link" name="pager" forward="news">Next</html:link>
</logic:equal>
<logic:equal value="false" property="hasNext" name="pager">Next</logic:equal>
</td>
</tr>
</table>
</logic:greaterThan>
</logicext:pager>
<bean:write name="pagerPanel" filter="false"/>
.... page of the list
<bean:write name="pagerPanel" filter="false"/>
