EJBSecurityManager

public EJBSecurityManager(EjbDescriptor ejbDescriptor,
                  org.glassfish.api.invocation.InvocationManager invMgr,
                  EJBSecurityManagerFactory fact)
                   throws Exception

Throws:

Exception

Method Detail

getUsesCallerIdentity

public boolean getUsesCallerIdentity()

loadPolicyConfiguration

public void loadPolicyConfiguration(EjbDescriptor eDescriptor)
                             throws Exception

Throws:

Exception

getContextID

public static String getContextID(EjbDescriptor ejbDesc)

authorize

public boolean authorize(org.glassfish.api.invocation.ComponentInvocation compInv)

This method is called by the EJB container to decide whether or not a method specified in the Invocation should be allowed.

Specified by:

authorize in interface com.sun.enterprise.security.SecurityManager

Parameters:

compInv - invocation object that contains all the details of the invocation.

Returns:

A boolean value indicating if the client should be allowed to invoke the EJB.

preInvoke

public void preInvoke(org.glassfish.api.invocation.ComponentInvocation inv)

This method is used by MDB Container - Invocation Manager to setup the run-as identity information. It has to be coupled with the postSetRunAsIdentity method. This method is called for EJB/MDB Containers

Specified by:

preInvoke in interface com.sun.enterprise.security.SecurityManager

postInvoke

public void postInvoke(org.glassfish.api.invocation.ComponentInvocation inv)

This method is used by Message Driven Bean Container to remove the run-as identity information that was set up using the preSetRunAsIdentity method

Specified by:

postInvoke in interface com.sun.enterprise.security.SecurityManager

isCallerInRole

public boolean isCallerInRole(String role)

This method returns a boolean value indicating whether or not the caller is in the specified role.

Specified by:

isCallerInRole in interface com.sun.enterprise.security.SecurityManager

Parameters:

role - role name in the form of java.lang.String

Returns:

A boolean true/false depending on whether or not the caller has the specified role.

getCallerPrincipal

public Principal getCallerPrincipal()

This method returns the Client Principal who initiated the current Invocation.

Specified by:

getCallerPrincipal in interface com.sun.enterprise.security.SecurityManager

Returns:

A Principal object of the client who made this invocation. or null if the SecurityContext has not been established by the client.

destroy

public void destroy()

Specified by:

destroy in interface com.sun.enterprise.security.SecurityManager

getCurrentSubject

public Subject getCurrentSubject()

This will return the subject associated with the current call. If the run as subject is in effect. It will return that subject. This is done to support the JACC specification which says if the runas principal is in effect, that principal should be used for making a component call.

Specified by:

getCurrentSubject in interface com.sun.enterprise.security.SecurityManager

Returns:

Subject the current subject. Null if this is not the run-as case

doAsPrivileged

public Object doAsPrivileged(PrivilegedExceptionAction pea)
                      throws Throwable

Specified by:

doAsPrivileged in interface com.sun.enterprise.security.SecurityManager

Throws:

Throwable

runMethod

public Object runMethod(Method beanClassMethod,
               Object obj,
               Object[] oa)
                 throws Throwable

Runs a business method of an EJB within the bean's policy context. The original policy context is restored after method execution. This method should only be used by com.sun.enterprise.security.SecurityUtil.

Parameters:

beanClassMethod - the EJB business method

obj - the EJB bean instance

oa - parameters passed to beanClassMethod

Returns:

return value from beanClassMethod

Throws:

InvocationTargetException - if the underlying method throws an exception

Throwable - other throwables in other cases

invoke

public Object invoke(Method beanClassMethod,
            boolean isLocal,
            Object o,
            Object[] oa)
              throws Throwable

This method is similiar to the runMethod, except it keeps the semantics same as the one in reflection. On failure, if the exception is caused due to reflection, it returns the InvocationTargetException. This method is called from the containers for ejbTimeout, WebService and MDBs.

Specified by:

invoke in interface com.sun.enterprise.security.SecurityManager

Parameters:

beanClassMethod, - the bean class method to be invoked

isLocal, - true if this invocation is through the local EJB view

o - the object on which this method is to be invoked in this case the ejb,

oa - the parameters for the method,

c, - the container instance can be a null value, where in the container will be queried to find its security manager.

Returns:

Object, the result of the execution of the method.

Throws:

Throwable

resetPolicyContext

public void resetPolicyContext()

Specified by:

resetPolicyContext in interface com.sun.enterprise.security.SecurityManager
