Copy Firefox settings to another machine

Recently, I moved to a new machine and needed to copy all my Firefox bookmarks, cookies, and passwords from the old box. A neat little utility does the job: MozBackup by Pavel Cvrcek. It exports the information to a file which can then be used on the new PC to import the settings. It even remembered all the sites I'd visited. The move to the new system was made much less painful thanks to this free utility.

15 CSS tricks that must be learned

Show/hide controls dynamically in JSF

We often need to show a set of controls dynamically based on what a user selects in a component in JSF. This example shows how to accomplish this in JSF and Seam, using the JBoss' EL extensions, which make life easier in your XHTML tags.

In this case, we're using an h:selectOneRadio control. We want to show and hide the rich:Panel controls; we wrap them in an a4j:outputPanel and then just re-render that when the user clicks a radio element. Note that for radio buttons, we have to use the onclick event; onchange is for h:selectOneMenu and other select controls.

<h:selectoneradio value="#{webencode.requestType}" id="rdoRequestType" styleclass="radio" layout="pageDirection">
<f:selectitem itemvalue="program" itemlabel="Series or Program">
<f:selectitem itemvalue="special" itemlabel="Special">
<a4j:support ajaxsingle="true" event="onclick" rerender="program">
</a4j:support>

<a4j:outputpanel id="program">
<rich:panel rendered="#{webencode.checkRequestType('program')}">
  program stuff goes here
</rich:panel>
<rich:panel rendered="#{webencode.checkRequestType('special')}">
  special stuff goes here
</rich:panel>
</a4j:outputpanel>

We can't call the equalsIgnoreCase() method on a string from within an EL expression, so we use a Seam method call that returns true/false based on string equality:

public Boolean checkRequestType(String requestType){
return (this.requestType.equalsIgnoreCase(requestType)) ? true : false;
}

With the a4j:support tag, we use AJAX to re-render the a4j:outputPanel when the user clicks the radio buttons. Then the custom checkRequestType() bean method is called and returns a Boolean based on the value of the radio button group.

Convert entity to selectItem in Seam

When using entity classes and Hibernate to display data in JBoss Seam, you can easily convert the entity to a selectItem element for use in a dropdown box, radio button group, or checkbox items. Here's an example:

<h:selectOneMenu >
  <f:selectItem itemLabel="" itemValue="#{null}"/>
  <s:selectItems var="tape" itemValue="#{tape.description}" 
  value="#{tapeformatList.resultList}" label="#{tape.description}" />
  <s:convertEntity/>
</h:selectOneMenu>

Note the null element to allow users to leave the selection blank. You can also achieve this by using the noSelectionLabel attribute. Also of note is the itemValue attribute on the Seam selectItems tag: This enables a custom value instead of the automatic numeric ID generated by Seam. In this case, the entity's description is used for the value.

Here's what this code generates in HTML:

<select name="tapeformatSearch:j_id14" size="1">    
 <option></option>
 <option value="VHS">VHS</option>
 <option value="DVD">DVD</option>
 <option value="Beta-SP">Beta-SP</option>
 <option value="Digi-Beta">Digi-Beta</option>

 <option value="HD-Cam">HD-Cam</option>
 <option value="DV-Cam">DV-Cam</option>
 <option value="Mini-DV">Mini-DV</option>
 <option value="DVC-PRO HD">DVC-PRO HD</option>
</select>
