## @hpas Tag Reference

Define HPAS-specific deployment descriptors (hp-ejb-jar.xml) for EJB beans.

Applies to: All EJB types

### @hpas Class Level Tags

@hpas.bean
@hpas.ejb-ref
@hpas.pool

### @hpas Method Level Tags

### @hpas Field Level Tags

## @hpas Class Level Tag Usage

### @hpas.bean (0..1)

Most of the class-level HPAS options are specified in parameters of this tag.

Applies to: class level of EJB

Parameter | Type | Applicability | Description | Mandatory
--- | --- | --- | --- | ---
read-only | bool | Applicable only to entity beans. | Specifies whether the bean is marked as read only. | false
passivation | bool | Applicable to stateful session beans and entity beans. For stateful session beans, if this parameter is used then the passivate-threshold parameter must also be present. | Determines whether the container can manage the passivation behaviour of beans; indicates whether passivation is enabled for the bean. | false
passivate-threshold | int |  | Specifies the number of beans for a deployed EJB above which the container will attempt to passivate instances. Applicable to stateful session beans only, when the passivation parameter has been used. | false
session-timeout | int |  | Indicates the timeout for the session. *** Note, int used because do not know what the f**k is duration | false
concurrent-message-processing | bool | Applicable to message driven beans only | Specifies whether concurrent message processing is enabled. | false
max-messages | int | Applicable to message driven beans only | Specifies the maximum number of messages assigned to a single session. This value is passed to the JMS server | false
max-message-threads | int | Applicable to message driven beans only | Specifies the maximum number of separate server sessions (threads) that will be created to handle messages | false
message-thread-timeout | int | Applicable to message driven beans only | Specifies the amount of time after which an idle server session will be available to be removed from the pool. | false
connection-retry | bool | Applicable to message driven beans only | Specifies whether an exception listener is registered for the connection. If no exception listener is established, there will be no connection failover. | false
jndi-factory | text | Applicable to message driven beans only | Specifies the lookup string used to obtain the factory that will be used to create the connection used by the MDB. | true
jndi-destination | text | Applicable to message driven beans only | Specifies the lookup string for the destination topic or queue for which the bean is registered as a listener. | true

### @hpas.ejb-ref (0..*)

A mapping of EJB references to deployed beans. NB This is likely to be refactored in the future, to use extra parameters on the @ejb:ejb-ref and @ejb:ejb-external-ref tags instead of the @hpas.ejb-ref tag.

Parameter | Type | Applicability | Description | Mandatory
--- | --- | --- | --- | ---
type | text |  | Use "co-located" for references to EJBs in the same application, and "distributed" for references to EJBs in other applications. Valid options are: co-located distributed Default value(s): co-located | true
ref-name | text |  | Specifies the mapping into the ejb-ref entry in the standard deployment descriptor. | true
jndi-name | text |  | Specifies the actual name under which the bean is registered in the name service. | true
application | text | Only applies when type="distributed". | Specifies the name of the application in which the EJB component is deployed. | false
host | text | Only applies when type="distributed". | Specifies the host name for the name server. | false
port | text | Only applies when type="distributed". | Specifies the port number for the name server | false

### @hpas.pool (0..1)

Contains the information required to setup an object pool.

Applies to: All beans

Parameter | Type | Applicability | Description | Mandatory
--- | --- | --- | --- | ---
initial-size | int |  | Specifies the initial size of the pool. | false
cache-limit | text |  | Specifies the maximum size of the pool. When the cache-limit is reached, pooled entries that are returned to the pool will be discarded; if the cache-limit is reached, new objects may still be created. NB: "integer or unlimited" is bullshit. How do I specify condition for this? Default value(s): unlimited | false
idle-timeout | int |  | Specifies the idle timeout for the pool. | false
use-reaper | bool |  | Specifies whether the pool should enforce the cache-limit. The reaper can be disabled to optimize pool performance. | false
reap-asynch | bool |  | Specifies whether pool reaping should occur asynchronously with respect to inserting or removing objects from the pool. Setting this to true makes pool accesses faster but consumes more system resources. | false
