@PostConstruct Method Not Called In JSF 2.0

[Andy Holm]

A method annotated with @PostConstruct on my managed bean is not being called in JSF 2.0.

Here is a snippet of my managed bean:

  @ManagedBean
@RequestScoped
public class InfoBean
{
	//properties removed...
	
	@PostConstruct
	public void validate() 
	{
                     //logic removed...
                }
}

Here's a snippet from my web.xml:

    <?xml version='1.0' encoding='UTF-8'?>

    <web-app version="2.5"
         xmlns="http://java.sun.com/xml/ns/javaee"
         xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
         xsi:schemaLocation="http://java.sun.com/xml/ns/javaee http://java.sun.com/xml/ns/javaee/web-app_2_5.xsd">

Here's my faces-config.xml

<faces-config xmlns="http://java.sun.com/xml/ns/javaee" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
    xsi:schemaLocation="http://java.sun.com/xml/ns/javaee http://java.sun.com/xml/ns/javaee/web-facesconfig_2_0.xsd"
    version="2.0">

</faces-config>

Here's a list of the jars I am using:

antlr-2.7.6.jar
commons-collections-3.1.jar
commons-el-1.0.jar
dom4j-1.6.1.jar
el-impl-2.2.0.jar
hibernate3.jar
javassist-3.9.0.GA.jar
jconn3.jar
jsf-api.jar
jsf-impl.jar
jta-1.1.jar
log4j-1.2.16.jar
slf4j-api-1.5.11.jar
slf4j-simple-1.5.11.jar
tomahawk-1.1.9.jar


Any ideas?

[Andy Holm]

No one has any idea? What more information could I include to help point to the problem?

You probably need to include the commons-annotations jar, since I didn't spot it in the list.

I haven't had problems in my JSF 2.0 projects, but I've had spotty results using this annotation in my JSF 1.x projects. I think the server may need some configuration in order to get the classloader to process the annotation properly.

Also, you need to know that if you're using Tomcat6, it should be release 6.0.18 or later, as there were bugs relating to inheritance of annotations in earlier versions. Specifically, inherited annotations weren't being processed.
