<!--
This is the XML DTD for the Servlet 2.3 deployment descriptor.
All Servlet 2.3 deployment descriptors must include a DOCTYPE
of the following form:

  <!DOCTYPE web-app PUBLIC
	"-//Sun Microsystems, Inc.//DTD Web Application 2.3//EN"
	"http://java.sun.com/dtd/web-app_2_3.dtd">

-->

<!--
The following conventions apply to all J2EE deployment descriptor
elements unless indicated otherwise.

- In elements that contain PCDATA, leading and trailing whitespace
  in the data may be ignored.

- In elements whose value is an "enumerated type", the value is
  case sensitive.

- In elements that specify a pathname to a file within the same
  JAR file, relative filenames (i.e., those not starting with "/")
  are considered relative to the root of the JAR file's namespace.
  Absolute filenames (i.e., those starting with "/") also specify
  names in the root of the JAR file's namespace.  In general, relative
  names are preferred.  The exception is .war files where absolute
  names are preferred for consistency with the servlet API.
-->


<!--
The web-app element is the root of the deployment descriptor for
a web application.
-->
<!ELEMENT web-app (icon?, display-name?, description?, distributable?,
context-param*, filter*, filter-mapping*, listener*, servlet*,
servlet-mapping*, session-config?, mime-mapping*, welcome-file-list?,
error-page*, taglib*, resource-env-ref*, resource-ref*, security-constraint*,
login-config?, security-role*, env-entry*, ejb-ref*,  ejb-local-ref*)>

<!--
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.


Used in: security-constraint
-->
<!ELEMENT auth-constraint (description?, role-name*)>

<!--
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".

Used in: login-config
-->
<!ELEMENT auth-method (#PCDATA)>

<!--
The context-param element contains the declaration of a web
application's servlet context initialization parameters.

Used in: web-app
-->
<!ELEMENT context-param (param-name, param-value, description?)>

<!--
The description element is used to provide text describing the parent
element.  The description element should include any information that
the web application war file producer wants to provide to the consumer of
the web application war file (i.e., to the Deployer). Typically, the tools
used by the web application war file consumer will display the description
when processing the parent element that contains the description.

Used in: auth-constraint, context-param, ejb-local-ref, ejb-ref,
env-entry, filter, init-param, resource-env-ref, resource-ref, run-as,
security-role, security-role-ref, servlet, user-data-constraint,
web-app, web-resource-collection
-->
<!ELEMENT description (#PCDATA)>

<!--
The display-name element contains a short name that is intended to be
displayed by tools.  The display name need not be unique.

Used in: filter, security-constraint, servlet, web-app

Example:

<display-name>Employee Self Service</display-name>
-->
<!ELEMENT display-name (#PCDATA)>

<!--
The distributable element, by its presence in a web application
deployment descriptor, indicates that this web application is
programmed appropriately to be deployed into a distributed servlet
container

Used in: web-app
-->
<!ELEMENT distributable EMPTY>

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

The name in the ejb-link element is 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 file
containing the web application that is referencing the enterprise bean.
This allows multiple enterprise beans with the same ejb-name to be
uniquely identified.

Used in: ejb-local-ref, ejb-ref

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 web application
	  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

Used in: web-app
-->
<!ELEMENT ejb-local-ref (description?, ejb-ref-name, ejb-ref-type,
		local-home, local, ejb-link?)>

<!--
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 web application 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

	  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 web application'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/".

Used in: ejb-local-ref, ejb-ref

Example:

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

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>

Used in: ejb-local-ref, ejb-ref
-->
<!ELEMENT ejb-ref-type (#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>

Used in: env-entry
