java.lang.Objectjava.security.Permission
javax.security.jacc.EJBMethodPermission
Class for EJB method permissions.
The name of an EJBMethodPermission contains the value of the ejb-name element in the application's deployment descriptor that identifies the target EJB.
The actions of an EJBMethodPermission identifies the methods of the EJB to which the permission applies.
Implementations of this class MAY implement newPermissionCollection or inherit its implementation from the super class.

Constructor Detail |
public EJBMethodPermission(java.lang.String name, java.lang.String actions)
The name contains the value of the ejb-name element corresponding to an EJB in the application's deployment descriptor.
The actions contains a methodSpec. The syntax of the actions parameter is defined as follows:
methodNameSpec ::= methodName | emptyString methodInterfaceName ::= String methodInterfaceSpec ::= methodInterfaceName | emptyString typeName ::= typeName | typeName [] methodParams ::= typeName | methodParams comma typeName methodParamsSpec ::= emptyString | methodParams methodSpec ::= null | methodNameSpec | methodNameSpec comma methodInterfaceName | methodNameSpec comma methodInterfaceSpec comma methodParamsSpec
A MethodInterfaceName is a non-empty String and should contain a method-intf value as defined for use in EJB deployment descriptors. An implementation must be flexible such that it supports additional interface names especially if they are standardized by the EJB Specification. The EJB Specification currently defines the following method-intf values:
{ "Home", "LocalHome", "Remote", "Local", "ServiceEndpoint" }
A null or empty string methodSpec indicates that the permission applies to all methods of the EJB. A methodSpec with a methodNameSpec of the empty string matches all methods of the EJB that match the methodInterface and methodParams elements of the methodSpec.
A methodSpec with a methodInterfaceSpec of the empty string matches all methods of the EJB that match the methodNameSpec and methodParamsSpec elements of the methodSpec.
A methodSpec without a methodParamsSpec matches all methods of the EJB that match the methodNameSpec and methodInterface elements of the methodSpec.
The order of the typeNames in methodParams array must match the order of occurence of the corresponding parameters in the method signature of the target method(s). Each typeName in the methodParams must contain the canonical form of the corresponding parameter's typeName as defined by the getActions method. A methodSpec with an empty methodParamsSpec matches all 0 argument methods of the EJB that match the methodNameSpec and methodInterfaceSpec elements of the methodSpec.
name
- of the EJB to which the permission pertains.
actions
- identifies the methods of the EJB to which the
permission pertains.public EJBMethodPermission(java.lang.String EJBName, java.lang.String methodName, java.lang.String methodInterface, java.lang.String[] methodParams)
EJBName
- The string representation of the name of the EJB as it
appears in the corresponding ejb-name element in the deployment
descriptor.
methodName
- A string that may be used to indicate the method of
the EJB to which the permission pertains. A value of null or ""
indicates that the permission pertains to all methods that
match the other parameters of the permission specification
without consideration of method name.
methodInterface
- A string that may be used to specify the EJB
interface to which the permission pertains. A value of null or "",
indicates that the permission pertains to all methods that match the
other parameters of the permission specification without consideration
of the interface they occur on.
methodParams
- An array of strings that may be used to specify
(by typeNames) the parameter signature of the target methods. The
order of the typeNames in methodParams array must match
the order of occurence of the corresponding parameters
in the method signature of the target method(s). Each typeName in
the methodParams array must contain the canonical form of the
corresponding parameter's typeName as defined by the getActions method.
An empty methodParams array is used to represent
a method signature with no arguments. A value of null indicates that
the permission pertains to all methods that match the other
parameters of the permission specification without consideration
of method signature.public EJBMethodPermission(java.lang.String EJBName, java.lang.String methodInterface, java.lang.reflect.Method method)
A container uses this constructor prior to checking if a caller has permission to call the method of an EJB.
EJBName
- The string representation of the name of the EJB as it
appears in the corresponding ejb-name element in the deployment
descriptor.
methodInterface
- A string that may be used to specify the EJB
interface to which the permission pertains.
A value of null or "", indicates that the permission pertains
to all methods that match the other parameters of the
permission specification without consideration of the
interface they occur on.
method
- an instance of the Java.lang.reflect.Method class
corresponding to the method that the container is trying to determine
whether the caller has permission to access. This value must not be
null.Method Detail |
public boolean equals(java.lang.Object o)
Two Permission objects, P1 and P2, are equivalent if and only if P1.implies(P2) && P2.implies(P1).
o
- the EJBMethodPermission object being tested for equality
with this EJBMethodPermission
public java.lang.String getActions()
methodNameSpec ::= methodName | emptyString methodInterfaceName ::= String methodInterfaceSpec ::= methodInterfaceName | emptyString typeName ::= typeName | typeName [] methodParams ::= typeName | methodParams comma typeName methodParamsSpec ::= emptyString | methodParams methodSpec ::= null | methodName | methodNameSpec comma methodInterfaceName | methodNameSpec comma methodInterfaceSpec comma methodParamsSpec
The canonical form of each typeName must begin with the fully qualified Java name of the corresponding parameter's type. The canonical form of a typeName for an array parameter is the fully qualified Java name of the array's component type followed by as many instances of the string "[]" as there are dimensions to the array. No additional characters (e.g. blanks) may occur in the canonical form.
A MethodInterfaceName is a non-empty String and should contain a method-intf value as defined for use in EJB deployment descriptors. An implementation must be flexible such that it supports additional interface names especially if they are standardized by the EJB Specification. The EJB Specification currently defines the following method-intf values:
{ "Home", "LocalHome", "Remote", "Local", "ServiceEndpoint" }
public int hashCode()
public boolean implies(java.security.Permission permission)
The argument permission applies to a subset of the methods to which this permission applies if all of the following conditions are met.
The name and actions comparisons described above are case sensitive.
permission
- "this" EJBMethodPermission is checked to see if
it implies the argument permission.
