JSF 1.1 DataTable Reuse - jsf

Question

I am working on a project that the previous programmer(s) duplicate code everywhere. I need to make a change to some JSF code but don't want to duplicate my changes every where. I figure there has to be a better way.
Here is the scenario; There are multiple dataTable that show up on several different tabs, all on the same page. Each dataTable is the same in every way except that the id and value/data source is different. I need to use the same technology that this was built with so I can't change the version or anything.
Setup:
Websphere 7
Java 1.5
JSF 1.1
Tomahawk 1.1
How can I externalize the dataTable and define the id and value when the dataTable is included? That way I don't have to make the same change multiple times for each table.
Tabbed Panel where each Edit.jsp page contains the dataTable below.
<odc:tabbedPanel id="sampleTab" styleClass="tabbedPanel_3"
slantActiveRight="4" slantActiveLeft="4" slantInactiveRight="4"
slantInactiveLeft="4" width="100%" height="100%"
variableTabLength="true" showBackNextButton="true" showTabs="true">
<!-- Start Test panel -->
<odc:bfPanel id="testsDisplayPanel" name="IPA"
showFinishCancelButton="false">
<jsp:include flush="true" page="editHeader.jsp" />
<jsp:include flush="true" page="testEdit.jsp" />
</odc:bfPanel>

<odc:bfPanel id="elisaDisplayPanel" name="ELISA"
showFinishCancelButton="false">

Answer 1

To solve this problem I broke up the jsf code into several jsp files and inserted them where needed.
dataTableElisa.jsp
<h:dataTable id="elisaTestResults" styleClass="data-entry"
value="#{pc_SampleEdit.sample.test.elisaTestResults}" var="elisaTestResults" border="0"
cellpadding="0" cellspacing="0" rowClasses="none, grey-highlight">
<jsp:include flush="true" page="innerTable.jsp"/>
</h:dataTable>
dataTableNmo.jsp
<h:dataTable id="nmoTestResults" styleClass="data-entry"

</h:dataTable>
