read-only

Specifies that a field is read-only if true. If this element is absent, the default value is false .

Superelements

cmp-field-mapping (sun-cmp-mappings.xml)

Subelements

none - contains data

realm

Specifies the name of the realm used to process all authentication requests associated with this application. If this element is not specified or does not match the name of a configured realm, the default realm is used. For more information about realms, see Realm Configuration in Sun Java System Application Server Platform Edition 9 Developer’s Guide.

Attributes

The following table describes attributes for the refresh-field element.

Table A–89 refresh-field Attributes


Attribute	Default	Description
`name`	none	Specifies the input parameter name.
`scope`	`request.parameter`	(optional) Specifies the scope from which the input parameter is retrieved. Allowed values are `context.attribute`, `request.header`, `request.parameter`, `request.cookie`, `session.id`, and `session.attribute`.

refresh-period-in-seconds

Specifies the rate at which a read-only-bean must be refreshed from the data source. If the value is less than or equal to zero, the bean is never refreshed; if the value is greater than zero, the bean instances are refreshed at the specified interval. This rate is just a hint to the container. Default is 0 (no refresh).

Superelements

ejb (sun-ejb-jar.xml)

Subelements

none - contains data

removal-timeout-in-seconds

Specifies the amount of time a bean instance can remain idle in the container before it is removed (timeout). A value of 0 specifies that the container does not remove inactive beans automatically. The default value is 5400.

If removal-timeout-in-seconds is less than or equal to cache-idle-timeout-in-seconds, beans are removed immediately without being passivated.

Applies to stateful session beans.

For related information, see cache-idle-timeout-in-seconds.

`auth-recipient`	none	Specifies whether recipient authentication occurs before or after content authentication. Allowed values are `before-content` and `after-content`.

res-ref-name

Specifies the res-ref-name in the corresponding Java EE deployment descriptor file resource-ref entry. The res-ref-name element specifies the name of a resource manager connection factory reference. The name must be unique within an enterprise bean.

Superelements

resource-ref (sun-web.xml, sun-ejb-jar.xml, sun-application-client.xml)

Subelements

none - contains data

resize-quantity

Specifies the number of bean instances to be:

Created, if a request arrives when the pool has less than steady-pool-size quantity of beans (applies to pools only for creation). If the pool has more than steady-pool-size minus resize-quantity of beans, then resize-quantity is still created.
Removed, when the pool-idle-timeout-in-seconds timer expires and a cleaner thread removes any unused instances.
- For caches, when max-cache-size is reached, resize-quantity beans are selected for passivation using the victim-selection-policy. In addition, the cache-idle-timeout-in-seconds or removal-timeout-in-seconds timers passivate beans from the cache.
- For pools, when the max-pool-size is reached, resize-quantity beans are selected for removal. In addition, the pool-idle-timeout-in-seconds timer removes beans until steady-pool-size is reached.

Values are from 0 to MAX_INTEGER. The pool is not resized below the steady-pool-size. Default is 16.

Applies to stateless session beans, entity beans, and message-driven beans.

For EJB pools, the value can be defined in the EJB container. Default is 16.

For EJB caches, the value can be defined in the EJB container. Default is 32.

For message-driven beans, the value can be defined in the EJB container. Default is 2.

When resource-ref specifies a JMS connection factory for the Sun Java System Message Queue, the default-resource-principal (name/password) must exist in the Message Queue user repository. Refer to the Security Management chapter in the Sun Java System Message Queue 3.7 UR1 Administration Guide for information on how to manage the Message Queue user repository.
