Problem:
When user clicks a save button, the entered values are validated in a Backing bean method based on a business rule. If the validation fails, a confirmation message or pop up should be displayed to the user whether the user wishes to continue with save.
Solution:
This is little tricky. We call the validation method inside the action method of save button. We have to use a hidden parameter whose value is set to true if the validation fails ie we need to prompt the user. Using a javascript check if the value of hidden parameter is true then show the confirmation message. When user clicks ok in the confirmation message, from the javascript call the action (save) method of a hidden command button. Call the javascript on loading the page
Here is the javascript
function showConfirmation(){
var value=document.getElementById('formId:valid').value;
if(value == "true"){
if(confirm("There are values that are at 0.Do you want to save the information ?")){
document.getElementById('formId:hiddenButton').click();
}else{
return false
}
}
}
<body onload=showConfirmation()>
<h:form id="formId">
<h:commandButton id="save" type="submit" value="Save" action="#{BackingBean.save}"/>
<h:inputHidden id="valid" value="#{BackingBean.showconfirmation}"/>
<h:commandButton id="hiddenButton" value="hidden" action="#{BackingBean.saveWithZero}" style="visibility:hidden;" />
</h:form>
</body>
Make sure that you set showconfirmation=false in your backing bean until you need to show the pop up.
When a command button is clicked, display a prompt to the user if user selects 'OK' execute the action other wise stay in the current page.
Solution:
Use javascript confirmation dialog in <commandButton>
<h:commandButton value="Save" action="#{BackingBean.save}" onclick="if (!confirm('Are you sure you want to save?')) return false" >
Problem :
To create a table from a list of objects obtained from DB in which each row has a button.On clicking the button the details of the row is displayed as next row.
This is not possible with JSF <h:dataTable>
Solution:
Use JSTL to iterate through the list and use plain html to create the table.
Use jsf components inside the <td> of the table
Here is the sample code
<table>
<tr class="colHdr">
<td >Column 1</td>
<td >Column 2</td>
<td >Column 3</td>
<td >Column 4</td>
<td >Column 5</td>
</tr>
<!-- use jstl1.2 for iterating the list of hardware objects-->
<c:forEach items="#{BackingBean.hardwareList}" var="hardware" varStatus="status">
<tr>
<td colspan="5" class="colStyle">
<h:outputText value="#{hardware.hardwareDesc}"/>
</td>
</tr>
<!--use status var to alter the row color -->
<tr class="${status.index % 2 == 0 ? 'style1' : 'style2'}">
<td> <!--use f:setPropertyActionListener to get which hardware's(row) detail button is clicked -->
<h:commandButton value="Hardware Details" action="#{BackingBean.details}">
f:setPropertyActionListener target="#{BackingBean.hardware}" value="#{hardware}" />
<!-- Backing bean must have getter and setter for hardware type -->
</h:commandButton>
</td>
<td><h:inputText size="4" value="#{hardware.col1}"/></td>
<td><h:inputText size="4" value="#{hardware.col2}"/></td>
<td><h:inputText size="4" value="#{hardware.col3}"/></td>
<td><h:inputText size="4" value="#{hardware.col4}"/></td>
<!-- this column is rendered only for hardware whose group is true-->
<td><h:inputText size="4" rendered="#{hardware.group}" value="#{hardware.col5}"/></td>
</tr>
<!-- On clicking the detail button set the showDetails
(of the corresponding hardware object obtained through the f:setPropertyActionListener)
to true in the backing bean -->
<h:panelGroup rendered="#{hardware.showDetails}">
<tr>
<td colspan="5">
<hr />
</td>
</tr>
<tr>
<td class="text1">Minimum</td>
<td class="text1"><h:outputText value="#{hardware.col1Min}"/></td>
<td class="text1"><h:outputText value="#{hardware.col2Min}"/></td>
<td class="text1"><h:outputText value="#{hardware.col3Min}"/></td>
<td class="text1"><h:outputText value="#{hardware.col4Min}"/></td>
<td class="text1"><h:outputText value="#{hardware.col5Min}"/></td>
</tr>
<tr>
<td class="genText">Optimal</td>
<td class="expLineAlt"><h:outputText value="#{hardware.col1Opt}"/></td>
<td class="expLineAlt"><h:outputText value="#{hardware.col2Opt}"/></td>

A Servlet is controlled by the Container. The servlet has only one state - Initialized.
The init() method of the Generic Servlet is called if it is not overriden in the MyServlet. The init() can be used to initalize the database before processing the request.
The service() method of the HttpServlet is called. We don't need to override it.
The service() method in HttpServlet calls the overrriden doGet() or doPost() of MyServlet.
