PolicyContext in Tomcat not being set in Tomcat 6.0.44

[Saurabh Sam]

I am using Apache-Tomcat version: 6.0.44 and my and OS is window 10.My Java version in jdk1.6.0_45.
I am using Jaas Realm for Authentication. My authentication is working well but when I tried to get HttpServletRequest object from javax.security.jacc.PolicyContext in login() method of my Custom Login class which extends javax.security.auth.spi.LoginModule by below code:

HttpServletRequest request = (HttpServletRequest) PolicyContext.getContext("javax.servlet.http.HttpServletRequest")

, I am getting below error:

“javax.security.auth.login.LoginException: java.lang.IllegalArgumentException: unknown handler key at javax.security.jacc.PolicyContext.getContext(PolicyContext.java:311)”

When I printed

PolicyContext.getContextID()

, it is returning null
and

PolicyContext.getHandlerKeys()

returning Blank array.

I have already set jaas.config and configuration in context.xml. My question is : Do I need to set PolicyContext explicitly in Tomcat ? If yes , how?
