The instance documents may indicate the published version of
the schema using the xsi:schemaLocation attribute for the
Java EE namespace with the following location:
http://java.sun.com/xml/ns/javaee/ejb-jar_3_1.xsd
]]>
The following conventions apply to all Java EE
deployment descriptor elements unless indicated otherwise.
- 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.
This is the root of the ejb-jar deployment descriptor.
The ejb-name element contains the name of an enterprise
bean. The name must be unique within the ejb-jar or
.war file.
The keyref indicates the references from
relationship-role-source must be to a specific ejb-name
defined within the scope of enterprise-beans element.
A role-name-key is specified to allow the references
from the security-role-refs.
The keyref indicates the references from
security-role-ref to a specified role-name.
The access-timeoutType represents the maximum amount of
time (in a given time unit) that the container should wait for
a concurrency lock before throwing a timeout exception to the
client.
A timeout value of 0 means concurrent access is not permitted.
A timeout value of -1 means wait indefinitely to acquire a lock.
The async-methodType element specifies that a session
bean method has asynchronous invocation semantics.
The activation-configType defines information about the
expected configuration properties of the message-driven bean
in its operational environment. This may include information
about message acknowledgement, message selector, expected
destination type, etc.
The configuration information is expressed in terms of
name/value configuration properties.
The properties that are recognized for a particular
message-driven bean are determined by the messaging type.
The activation-config-propertyType contains a name/value
configuration property pair for a message-driven bean.
The properties that are recognized for a particular
message-driven bean are determined by the messaging type.
The activation-config-property-name element contains
the name for an activation configuration property of
a message-driven bean.
For JMS message-driven beans, the following property
names are recognized: acknowledgeMode,
messageSelector, destinationType, subscriptionDurability
The activation-config-property-value element
contains the value for an activation configuration
property of a message-driven bean.
The around-invoke type specifies a method on a
class to be called during the around invoke portion of an
ejb invocation. Note that each class may have only one
around invoke method and that the method may not be
overloaded.
If the class element is missing then
the class defining the callback is assumed to be the
interceptor class or component class in scope at the
location in the descriptor in which the around invoke
definition appears.
The around-timeout type specifies a method on a
class to be called during the around-timeout portion of
a timer timeout callback. Note that each class may have
only one around-timeout method and that the method may not
be overloaded.
If the class element is missing then
the class defining the callback is assumed to be the
interceptor class or component class in scope at the
location in the descriptor in which the around-timeout
definition appears.
The assembly-descriptorType defines
application-assembly information.
The application-assembly information consists of the
following parts: the definition of security roles, the
definition of method permissions, the definition of
transaction attributes for enterprise beans with
container-managed transaction demarcation, the definition
of interceptor bindings, a list of
methods to be excluded from being invoked, and a list of
exception types that should be treated as application exceptions.
All the parts are optional in the sense that they are
omitted if the lists represented by them are empty.
Providing an assembly-descriptor in the deployment
descriptor is optional for the ejb-jar or .war file producer.
The cmp-fieldType describes a container-managed field. The
cmp-fieldType contains an optional description of the field,
and the name of the field.
The field-name element specifies the name of a
container managed field.
The name of the cmp-field of an entity bean with

methods for the relationship. The cmr-field-type element is
used only for collection-valued cmr-fields. It specifies the
type of the collection that is used.
The cmr-field-name element specifies the name of a
logical relationship field in the entity bean
class. The name of the cmr-field must begin with a
lowercase letter. This field is accessed by methods
whose names consist of the name of the field
specified by cmr-field-name in which the first
letter is uppercased, prefixed by "get" or "set".
The cmr-field-type element specifies the class of a
collection-valued logical relationship field in the entity
bean class. The value of an element using cmr-field-typeType
must be either: java.util.Collection or java.util.Set.
The concurrency-management-typeType specifies the way concurrency
is managed for a singleton or stateful session bean.
The concurrency management type must be one of the following:
Bean
Container
Bean managed concurrency can only be specified for a singleton bean.

must manage transaction scopes for the enterprise bean's
method invocations. It defines an optional description, a
list of method elements, and a transaction attribute. The
transaction attribute is to be applied to all the specified
methods.
The depends-onType is used to express initialization
ordering dependencies between Singleton components.
The depends-onType specifies the names of one or more
Singleton beans in the same application as the referring
Singleton, each of which must be initialized before
the referring bean.
Each dependent bean is expressed using ejb-link syntax.
The order in which dependent beans are initialized at
runtime is not guaranteed to match the order in which
they are listed.

]]>
The version specifies the version of the
EJB specification that the instance document must
comply with. This information enables deployment tools
to validate a particular EJB Deployment
Descriptor with respect to a specific version of the EJB
schema.
The metadata-complete attribute defines whether this
deployment descriptor and other related deployment
descriptors for this module (e.g., web service
descriptors) are complete, or whether the class
files available to this module and packaged with
this application should be examined for annotations
that specify deployment information.
If metadata-complete is set to "true", the deployment
tool must ignore any annotations that specify deployment
information, which might be present in the class files
of the application.
If metadata-complete is not specified or is set to
"false", the deployment tool must examine the class
files of the application for annotations, as
specified by the specifications.

EJBNAME*
This style is used to refer to all the methods of the
specified enterprise bean's business, home, component,
and/or web service endpoint interfaces.
2.
EJBNAMEMETHOD
This style is used to refer to the specified method of
the specified enterprise bean. If there are multiple
methods with the same overloaded name, the element of
this style refers to all the methods with the overloaded
name.
3.
EJBNAMEMETHODPARAM-1PARAM-2
...
PARAM-n
This style is used to refer to a single method within a
set of methods with an overloaded name. PARAM-1 through
PARAM-n are the fully-qualified Java types of the
method's input parameters (if the method has no input
arguments, the method-params element contains no
method-param elements). Arrays are specified by the
array element's type, followed by one or more pair of
square brackets (e.g. int[][]). If there are multiple
methods with the same overloaded name, this style refers
to all of the overloaded methods.
Examples:
Style 1: The following method element refers to all the
methods of the EmployeeService bean's business, home,
component, and/or web service endpoint interfaces:
EmployeeService*
Style 2: The following method element refers to all the
create methods of the EmployeeService bean's home
interface(s).
EmployeeServicecreate
Style 3: The following method element refers to the
create(String firstName, String LastName) method of the
EmployeeService bean's home interface(s).
EmployeeServicecreatejava.lang.Stringjava.lang.String
The following example illustrates a Style 3 element with
more complex parameter types. The method
foobar(char s, int i, int[] iar, mypackage.MyClass mycl,
mypackage.MyClass[][] myclaar) would be specified as:
EmployeeServicefoobarcharintint[]mypackage.MyClassmypackage.MyClass[][]
The optional method-intf element can be used when it becomes
necessary to differentiate between a method that is multiply
defined across the enterprise bean's business, home, component,
and/or web service endpoint interfaces with the same name and
signature. However, if the same method is a method of both the
local business interface, and the local component interface,
the same attribute applies to the method for both interfaces.
Likewise, if the same method is a method of both the remote
business interface and the remote component interface, the same
attribute applies to the method for both interfaces.
For example, the method element
EmployeeServiceRemotecreatejava.lang.Stringjava.lang.String
can be used to differentiate the create(String, String)
method defined in the remote interface from the
create(String, String) method defined in the remote home
interface, which would be defined as
EmployeeServiceHomecreatejava.lang.Stringjava.lang.String
and the create method that is defined in the local home
interface which would be defined as
EmployeeServiceLocalHomecreatejava.lang.Stringjava.lang.String
The method-intf element can be used with all three Styles
of the method element usage. For example, the following
method element example could be used to refer to all the
methods of the EmployeeService bean's remote home interface
and the remote business interface.
EmployeeServiceHome*
]]>
The method-intf element allows a method element to
differentiate between the methods with the same name and
signature that are multiply defined across the home and
component interfaces (e.g, in both an enterprise bean's
remote and local interfaces or in both an enterprise bean's
home and remote interfaces, etc.); the component and web
service endpoint interfaces, and so on.
Local applies to the local component interface, local business
interfaces, and the no-interface view.
Remote applies to both remote component interface and the remote
business interfaces.
ServiceEndpoint refers to methods exposed through a web service
endpoint.
Timer refers to the bean's timeout callback methods.
MessageEndpoint refers to the methods of a message-driven bean's
message-listener interface.
The method-intf element must be one of the following:
Home
Remote
LocalHome
Local
ServiceEndpoint
Timer
MessageEndpoint
The method-nameType contains a name of an enterprise
bean method or the asterisk (*) character. The asterisk is
used when the element denotes all the methods of an

fully-qualified Java type names of the method parameters.
The method-param element contains a primitive
or a fully-qualified Java type name of a method
parameter.
The method-permissionType specifies that one or more
security roles are allowed to invoke one or more enterprise
bean methods. The method-permissionType consists of an

The security roles used in the method-permissionType
must be defined in the security-role elements of the
deployment descriptor, and the methods must be methods
defined in the enterprise bean's business, home, component
and/or web service endpoint interfaces.
The unchecked element specifies that a method is

afterBegin, beforeCompletion, and/or afterCompletion methods
- an optional list of the session bean class and/or
superclass around-invoke methods.
- an optional list of the session bean class and/or
superclass around-timeout methods.

to be used for the execution of the bean's methods
- an optional declaration of the bean's resource
manager connection factory references
- an optional declaration of the bean's resource
environment references.
- an optional declaration of the bean's message
destination references
The elements that are optional are "optional" in the sense
that they are omitted when if lists represented by them are
empty.
The service-endpoint element may only be specified if the
bean is a stateless session bean.
The local-bean element declares that this
session bean exposes a no-interface Local client view.
The service-endpoint element contains the
fully-qualified name of the enterprise bean's web
service endpoint interface. The service-endpoint
element may only be specified for a stateless
session bean. The specified interface must be a
valid JAX-RPC service endpoint interface.
The ejb-class element specifies the fully qualified name
of the bean class for this ejb. It is required unless
there is a component-defining annotation for the same
ejb-name.
The timeout-method element specifies the method that
will receive callbacks for programmatically
created timers.
The init-on-startup element specifies that a Singleton
bean has eager initialization.
This element can only be specified for singleton session
beans.
The init-method element specifies the mappings for
EJB 2.x style create methods for an EJB 3.x bean.
This element can only be specified for stateful
session beans.
The remove-method element specifies the mappings for
EJB 2.x style remove methods for an EJB 3.x bean.
This element can only be specified for stateful
session beans.
The session-typeType describes whether the session bean is a
singleton, stateful or stateless session. It is used by
session-type elements.
The value must be one of the three following:
Singleton
Stateful
Stateless
The stateful-timeoutType represents the amount of time
a stateful session bean can be idle(not receive any client
invocations) before it is eligible for removal by the container.
A timeout value of 0 means the bean is immediately eligible for removal.
A timeout value of -1 means the bean will never be removed due to timeout.
The time-unit-typeType represents a time duration at a given
unit of granularity.
The time unit type must be one of the following :
Days
Hours
Minutes
Seconds
Milliseconds
Microseconds
Nanoseconds
The timerType specifies an enterprise bean timer. Each
timer is automatically created by the container upon
deployment. Timer callbacks occur based on the
schedule attributes. All callbacks are made to the
timeout-method associated with the timer.
A timer can have an optional start and/or end date. If
a start date is specified, it takes precedence over the
associated timer schedule such that any matching
expirations prior to the start time will not occur.
Likewise, no matching expirations will occur after any
end date. Start/End dates are specified using the
XML Schema dateTime type, which follows the ISO-8601
standard for date(and optional time-within-the-day)
representation.
An optional flag can be used to control whether
this timer has persistent(true) delivery semantics or
non-persistent(false) delivery semantics. If not specified,
the value defaults to persistent(true).
A time zone can optionally be associated with a timer.
If specified, the timer's schedule is evaluated in the context
of that time zone, regardless of the default time zone in which
the container is executing. Time zones are specified as an
ID string. The set of required time zone IDs is defined by
the Zone Name(TZ) column of the public domain zoneinfo database.
An optional info string can be assigned to the timer and
retrieved at runtime through the Timer.getInfo() method.
The timerType can only be specified on stateless session
beans, singleton session beans, and message-driven beans.
The trans-attributeType specifies how the container must
manage the transaction boundaries when delegating a method
invocation to an enterprise bean's business method.
The value must be one of the following:
NotSupported
Supports
