public final Class WebUserDataPermission

Creates a new WebUserDataPermission with the specified name and actions.

The name contains a URLPatternSpec that identifies the web resources to which the permissions applies. The syntax of a URLPatternSpec is as follows:

         URLPatternList ::= URLPattern | URLPatternList colon URLPattern

         URLPatternSpec ::= null | URLPattern | URLPattern colon URLPatternList

A null URLPatternSpec is translated to the default URLPattern, "/", by the permission constructor. The empty string is an exact URLPattern, and may occur anywhere in a URLPatternSpec that an exact URLPattern may occur. The first URLPattern in a URLPatternSpec may be any of the pattern types, exact, path-prefix, extension, or default as defined in the Jakarta Servlet Specification). When a URLPatternSpec includes a URLPatternList, the patterns of the URLPatternList identify the resources to which the permission does NOT apply and depend on the pattern type and value of the first pattern as follows:

• No pattern may exist in the URLPatternList that matches the first pattern.
• If the first pattern is a path-prefix pattern, only exact patterns matched by the first pattern and path-prefix patterns matched by, but different from, the first pattern may occur in the URLPatternList.
• If the first pattern is an extension pattern, only exact patterns that are matched by the first pattern and path-prefix patterns may occur in the URLPatternList.
• If the first pattern is the default pattern, "/", any pattern except the default pattern may occur in the URLPatternList.
• If the first pattern is an exact pattern a URLPatternList must not be present in the URLPatternSpec.

The actions parameter contains a comma separated list of HTTP methods that may be followed by a transportType separated from the HTTP method by a colon.

         ExtensionMethod ::= any token as defined by RFC 2616
                 (that is, 1*[any CHAR except CTLs or separators])

         HTTPMethod ::= "Get" | "POST" | "PUT" | "DELETE" | "HEAD" |
                 "OPTIONS" | "TRACE" | ExtensionMethod

         HTTPMethodList ::= HTTPMethod | HTTPMethodList comma HTTPMethod

         HTTPMethodExceptionList ::= exclaimationPoint HTTPMethodList

         HTTPMethodSpec ::= emptyString | HTTPMethodExceptionList |
                 HTTPMethodList

         transportType ::= "INTEGRAL" | "CONFIDENTIAL" | "NONE"

         actions ::= null | HTTPMethodSpec |
                 HTTPMethodSpec colon transportType

If duplicates occur in the HTTPMethodSpec they must be eliminated by the permission constructor.

An empty string HTTPMethodSpec is a shorthand for a List containing all the possible HTTP methods.

If the HTTPMethodSpec contains an HTTPMethodExceptionList (i.e., it begins with an exclaimationPoint), the permission pertains to all methods except those occuring in the exception list.

An actions string without a transportType is a shorthand for a actions string with the value "NONE" as its TransportType.

A granted permission representing a transportType of "NONE", indicates that the associated resources may be accessed using any connection type.

Parameters

name:String

the URLPatternSpec that identifies the application specific web resources to which the permission pertains. All URLPatterns in the URLPatternSpec are relative to the context path of the deployed web application module, and the same URLPattern must not occur more than once in a URLPatternSpec. A null URLPatternSpec is translated to the default URLPattern, "/", by the permission constructor. All colons occuring within the URLPattern elements of the URLPatternSpec must be represented in escaped encoding as defined in RFC 2396.

actions:String

identifies the HTTP methods and transport type to which the permission pertains. If the value passed through this parameter is null or the empty string, then the permission is constructed with actions corresponding to all the possible HTTP methods and transportType "NONE".

Creates a new WebUserDataPermission with name corresponding to the URLPatternSpec, and actions composed from the array of HTTP methods and the transport type.

Parameters

urlPatternSpec:String

the URLPatternSpec that identifies the application specific web resources to which the permission pertains. All URLPatterns in the URLPatternSpec are relative to the context path of the deployed web application module, and the same URLPattern must not occur more than once in a URLPatternSpec. A null URLPatternSpec is translated to the default URLPattern, "/", by the permission constructor. All colons occurring within the URLPattern elements of the URLPatternSpec must be represented in escaped encoding as defined in RFC 2396.

HTTPMethods:String[]

an array of strings each element of which contains the value of an HTTP method. If the value passed through this parameter is null or is an array with no elements, then the permission is constructed with actions corresponding to all the possible HTTP methods.

transportType:String

a String whose value is a transportType. If the value passed through this parameter is null, then the permission is constructed with actions corresponding to transportType "NONE".

Creates a new WebUserDataPermission from the HttpServletRequest object.

Parameters

request:HttpServletRequest

the HttpServletRequest object corresponding to the Jakarta Servlet operation to which the permission pertains. The permission name is the substring of the requestURI (HttpServletRequest.getRequestURI()) that begins after the contextPath (HttpServletRequest.getContextPath()). When the substring operation yields the string "/", the permission is constructed with the empty string as its name. The constructor must transform all colon characters occurring in the name to escaped encoding as defined in RFC 2396. The HTTP method component of the permission's actions is as obtained from HttpServletRequest.getMethod(). The TransportType component of the permission's actions is determined by calling HttpServletRequest.isSecure().
