JAVA Servlet2.3外文书籍源码

<!--
The web-resource-name contains the name of this web resource
collection
-->

<!ELEMENT web-resource-name (#PCDATA)>

<!--
The http-method contains an HTTP method (GET | POST |...)
-->

<!ELEMENT http-method (#PCDATA)>

<!--
The user-data-constraint element is used to indicate how data
communicated between the client and container should be protected
-->

<!ELEMENT user-data-constraint (description?, transport-guarantee)>

<!--
The transport-guarantee element specifies that the communication
between client and server should be NONE, INTEGRAL, or
CONFIDENTIAL. NONE means that the application does not require any
transport guarantees. A value of INTEGRAL means that the application
requires that the data sent between the client and server be sent in
such a way that it can't be changed in transit. CONFIDENTIAL means
that the application requires that the data be transmitted in a
fashion that prevents other entities from observing the contents of
the transmission. In most cases, the presence of the INTEGRAL or
CONFIDENTIAL flag will indicate that the use of SSL is required.
-->

<!ELEMENT transport-guarantee (#PCDATA)>

<!--
The auth-constraint element indicates the user roles that should
be permitted access to this resource collection. The role-name 
used here must either correspond to the role-name of one of the 
security-role elements defined for this web application, or be 
the specially reserved role-name "*" that is a compact syntax for 
indicating all roles in the web application. If both "*" and 
rolenames appear, the container interprets this as all roles.
If no roles are defined, no user is allowed access to the portion of
the web application described by the containing security-constraint.
The container matches role names case sensitively when determining 
access.
-->

<!ELEMENT auth-constraint (description?, role-name*)>

<!--
The role-name element contains the name of a security role.
-->

<!ELEMENT role-name (#PCDATA)>

<!--
The login-config element is used to configure the authentication
method that should be used, the realm name that should be used for
this application, and the attributes that are needed by the form login
mechanism.
-->

<!ELEMENT login-config (auth-method?, realm-name?, form-login-config?)>

<!--
The realm name element specifies the realm name to use in HTTP
Basic authorization
-->

<!ELEMENT realm-name (#PCDATA)>

<!--
The form-login-config element specifies the login and error pages
that should be used in form based login. If form based authentication
is not used, these elements are ignored.
-->

<!ELEMENT form-login-config (form-login-page, form-error-page)>

<!--
The form-login-page element defines the location in the web app
where the page that can be used for login can be found. The path
begins with a leading / and is interpreted relative to the root of the
WAR.
-->

<!ELEMENT form-login-page (#PCDATA)>

<!--
The form-error-page element defines the location in the web app
where the error page that is displayed when login is not successful
can be found. The path begins with a leading / and is interpreted 
relative to the root of the WAR.

-->

<!ELEMENT form-error-page (#PCDATA)>

<!--
The auth-method element is used to configure the authentication
mechanism for the web application. As a prerequisite to gaining 
access to any web resources which are protected by an authorization
constraint, a user must have authenticated using the configured
mechanism. Legal values for this element are "BASIC", "DIGEST",
"FORM", or "CLIENT-CERT".
-->

<!ELEMENT auth-method (#PCDATA)>

<!--
The security-role element contains the declaration of a security
role which is used in the security-constraints placed on the web
application.
-->

<!ELEMENT security-role (description?, role-name)>

<!--
The security-role-ref element defines a mapping between the name of 
role called from a Servlet using 
isUserInRole(String name) and the name of a security role defined 
for the web application. For example, 
to map the security role reference "FOO" to the security role 
with role-name "manager" the sytax would 
be:

<security-role-ref>
  



<role-name>FOO</role-name>
  
<role-link>manager</manager>
</security-role-ref>

In this case if the servlet called by a user belonging to the "manager" 
security role made the API call 
isUserInRole("FOO") the result would be true.
Since the role-name "*" has a special meaning for authorization 
constraints, its value is not permitted here.
-->

<!ELEMENT security-role-ref (description?, role-name, role-link)>

<!--
The role-link element is used to link a security role reference
to a defined security role. The role-link element must contain the
name of one of the security roles defined in the security-role
elements.
-->

<!ELEMENT role-link (#PCDATA)>

<!--
The env-entry element contains the declaration of a web application's
environment entry. The declaration consists of an optional
description, the name of the environment entry, and an optional
value.  If a value is not specified, one must be supplied
during deployment.
-->

<!ELEMENT env-entry (description?, env-entry-name, env-entry-value?,
env-entry-type)>

<!--
The env-entry-name element contains the name of a web applications's
environment entry.  The name is a JNDI name relative to the
java:comp/env context.  The name must be unique within a web application.

Example: 

<env-entry-name>minAmount</env-entry-name>
-->

<!ELEMENT env-entry-name (#PCDATA)>

<!--
The env-entry-value element contains the value of A_COMPONENT's
environment entry. The value must be a String that is valid for the
constructor of the specified type that takes a single String
parameter, or for java.lang.Character, a single character.

Example: 

<env-entry-value>100.00</env-entry-value>
-->

<!ELEMENT env-entry-value (#PCDATA)>

<!--
The env-entry-type element contains the fully-qualified Java type of
the environment entry value that is expected by THE_COMPONENT's
code.

The following are the legal values of env-entry-type:

	java.lang.Boolean
	java.lang.Byte
	java.lang.Character
	java.lang.String
	java.lang.Short
	java.lang.Integer
	java.lang.Long
	java.lang.Float
	java.lang.Double
-->

<!ELEMENT env-entry-type (#PCDATA)>

<!--
The ejb-ref element is used for the declaration of a reference to
an enterprise bean's home. The declaration consists of:

	- an optional description
	- the EJB reference name used in the code of
	  the servlet that's referencing the enterprise bean
	- the expected type of the referenced enterprise bean
	- the expected home and remote interfaces of the referenced
	  enterprise bean
	- optional ejb-link information, used to specify the referenced
	  enterprise bean
 
-->

<!ELEMENT ejb-ref (description?, ejb-ref-name, ejb-ref-type, home, 
remote, ejb-link?)>

<!--
The ejb-ref-name element contains the name of an EJB reference. The
EJB reference is an entry in the servlet's environment and is
relative to the java:comp/env context.  The name must be unique
within the web application.

It is recommended that name is prefixed with "ejb/".

Example: 

<ejb-ref-name>ejb/Payroll</ejb-ref-name>
-->

<!ELEMENT ejb-ref-name (#PCDATA)>

<!-- The ejb-ref-type element contains the expected type of the 
referenced enterprise bean. The ejb-ref-type element must be one of the following:

   <ejb-ref-type>Entity</ejb-ref-type>
   <ejb-ref-type>Session</ejb-ref-type>
-->

<!ELEMENT ejb-ref-type (#PCDATA)>

<!--
The home element contains the fully-qualified name of the enterprise
bean's home interface.

Example:

<home>com.aardvark.payroll.PayrollHome</home>
-->

<!ELEMENT home (#PCDATA)>

<!--
The remote element contains the fully-qualified name of the enterprise
bean's remote interface.

Example: 

<remote>com.wombat.empl.EmployeeService</remote>
-->

<!ELEMENT remote (#PCDATA)>

<!--
The ejb-link element is used in the ejb-ref or ejb-local-ref
elements to specify that an EJB reference is linked to another
enterprise bean.

The value of the ejb-link element must be the ejb-name of an
enterprise bean in the same J2EE application unit.

The name in the ejb-link element may be composed of a
path name specifying the ejb-jar containing the referenced enterprise
bean with the ejb-name of the target bean appended and separated from
the path name by "#".  The path name is relative to the WAR
containing the web application that is referencing the enterprise bean.
This allows multiple enterprise beans with the same ejb-name to be
uniquely identified.

Examples: 

	<ejb-link>EmployeeRecord</ejb-link>

	<ejb-link>../products/product.jar#ProductEJB</ejb-link>

-->

<!ELEMENT ejb-link (#PCDATA)>


<!--
The ejb-local-ref element is used for the declaration of a reference to
an enterprise bean's local home. The declaration consists of:

	- an optional description
	- the EJB reference name used in the code of THE_COMPONENT
	  that's referencing the enterprise bean
	- the expected type of the referenced enterprise bean
	- the expected local home and local interfaces of the referenced
	  enterprise bean
	- optional ejb-link information, used to specify the referenced
	  enterprise bean
-->

<!ELEMENT ejb-local-ref (description?, ejb-ref-name, ejb-ref-type,
		local-home, local, ejb-link?)>

<!-- 

The local element contains the fully-qualified name of the
enterprise bean's local interface. 

Used by ejb-local-ref

-->
<!ELEMENT local (#PCDATA)>

<!-- 

The local-home element contains the fully-qualified name of the
enterprise bean's local home interface. 

Used by ejb-local-ref
-->
<!ELEMENT local-home (#PCDATA)>




<!--
The run-as element, if defined for a servlet, overrides the security 
identity used to call an EJB
by that servlet in this web application. The role-name is one of the 
security roles already
defined for this web application.

Used by: <servlet>
-->
<!ELEMENT run-as (description?, role-name)>



<!--
The ID mechanism is to allow tools to easily make tool-specific
references to the elements of the deployment descriptor. This allows
tools that produce additional deployment information (i.e information
beyond the standard deployment descriptor information) to store the
non-standard information in a separate file, and easily refer from
these tools-specific files to the information in the standard web-app
deployment descriptor.
