PropertyNotFoundException Target Unreachable, identifier ‘patientBean’ resolved to null

I have been trying to get a simple @ManagedBean example working without the use of faces-config.xml. My bean is fairly simple:

@ManagedBean(name = "patientBean")
@SessionScoped
public class PatientBean {
    Integer randomInt = null;
    Integer userNumber = null;
    String response = "test";
    private long maximum = 10;
    private long minimum = 0;

But when I try to access this through a simple facelet page such as:

<h:inputText
 id="userNo"
 value="#{patientBean.userNumber}">

I get this error complainign about the managed bean target:

While I have searched the net looking for the answer without luck, I stubled upon the issue. In the maven war plugin, there was an attribute to <archiveClasses>true</archiveClasses> which creates a jar of all classes and adds that jar to the WEB-INF/lib directory.

<plugin>
 <groupId>org.apache.maven.plugins</groupId>
 <artifactId>maven-war-plugin</artifactId>
 <version>${plugin-war-version}</version>
 <configuration>
 <archive>
 <addMavenDescriptor>false</addMavenDescriptor>
 </archive>
 <strong><archiveClasses>true</archiveClasses></strong>
 <failOnMissingWebXml>false</failOnMissingWebXml>
 </configuration>
 </plugin>

This causes the bean to not be found unless I mapped it directly into the faces-config.xml:

<managed-bean>
 <managed-bean-name>patientBean</managed-bean-name>
 <managed-bean-class>com.baselogic.chapter03.web.PatientBean</managed-bean-class>
 <managed-bean-scope>session</managed-bean-scope>
 </managed-bean>

setting this to false in the maven-war-plugin allowed me to remove the faces-config.xml entry.

<archiveClasses>false</archiveClasses>
