Java EE (Java Enterprise Edition) General Discussion

Hi,

I am newbie to jsf. I have 2 Double fields one is lower limit and other one upper limit.

I want to compare those 2 field values 'upper limit' should be greater than the 'lower limit'.

If upper limit entered is less than lower limit and when user clicks the submit button it should display error message in UI.
<code>
<tr>
<td width="30%" align="right"><b><h:outputText id="lLowerMileLimit" value="Lower Mile Limit" /></b><span style="color:red">*</span>
</td>
<td width="50%" align="left">: <h:inputText id="lowerMileLimit" value="#{awardZoneMast.lowerMileLimit}" required="true" >
<t:validateRegExpr pattern="((^\d{1,10}$)|(^\d{1,10}\.\d{0,6}$))" />
</h:inputText>
<h:message for="lowerMileLimit" showSummary="true" showDetail="false" style="color:red" />
</td>
</tr>

<tr>
<td width="30%" align="right"><b><h:outputText id="uUpperMileLimit" value="Upper Mile Limit" /></b><span style="color:red">*</span>
</td>
<td width="50%" align="left">: <h:inputText id="upperMileLimit" value="#{awardZoneMast.upperMileLimit}" required="true">
<t:validateRegExpr pattern="((^\d{1,10}$)|(^\d{1,10}\.\d{0,6}$))" />
</h:inputText>
<h:message for="upperMileLimit" showSummary="true" showDetail="false" style="color:red" />
</td>
</tr>
</code>
