Null pointer exception is coming while trying to load application context while migrating to jsf 1.2.

Below is the stack trace

Below is the faces-xml

 <managed-bean>
    <description>This bean is used for customer profile</description>
    <managed-bean-name>CustomerSearchBean</managed-bean-name>
    <managed-bean-class>com.tms.cdqi.presentation.jsf.bean.customerprofile.CustomerSearchBean</managed-bean-class>
    <managed-bean-scope>request</managed-bean-scope>
    <managed-property>
        <property-name>commandInvoker</property-name>
        <value>#{commandInvoker}</value>
    </managed-property>
    <managed-property>
        <property-name>applicationContextFactory</property-name>
        <value>#{cdqiApplicationContextFactory}</value>
    </managed-property>

</managed-bean>

Edit 1: Below is the Application context xml

       <beans xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
  xmlns="http://www.springframework.org/schema/beans"
  xsi:schemaLocation="
            http://www.springframework.org/schema/beans
     http://www.springframework.org/schema/beans/spring-beans.xsd">

<bean id="cdqiApplicationContextFactory"
    class="com.tms.cdqi.framework.context.CDQIApplicationContextFactoryImpl" />

Edit 2 Code

    The application context  where null pointer is occurring

    CDQIApplicationContext context = this.getApplicationContextFactory()
            .getApplicationContext();
