Method Detail

getAllSystemRAResourcesAndPools

public Collection<Resource> getAllSystemRAResourcesAndPools()

Description copied from interface: ConnectorRuntimeExtension

Return the collection of system resources and pools.

Specified by:

getAllSystemRAResourcesAndPools in interface ConnectorRuntimeExtension

Returns:

collection of system resources and pools.

registerDataSourceDefinitions

public void registerDataSourceDefinitions(Application application)

Specified by:

registerDataSourceDefinitions in interface ConnectorRuntimeExtension

unRegisterDataSourceDefinitions

public void unRegisterDataSourceDefinitions(Application application)

Specified by:

unRegisterDataSourceDefinitions in interface ConnectorRuntimeExtension

lookupDataSourceInDAS

public Object lookupDataSourceInDAS(ResourceInfo resourceInfo)
                             throws ConnectorRuntimeException

Get a wrapper datasource specified by the jdbcjndi name This API is intended to be used in the DAS. The motivation for having this API is to provide the CMP backend/ JPA-Java2DB a means of acquiring a connection during the codegen phase. If a user is trying to deploy an JPA-Java2DB app on a remote server, without this API, a resource reference has to be present both in the DAS and the server instance. This makes the deployment more complex for the user since a resource needs to be forcibly created in the DAS Too. This API will mitigate this need.

Specified by:

lookupDataSourceInDAS in interface ConnectorRuntimeExtension

Parameters:

resourceInfo - the jndi name of the resource

Returns:

DataSource representing the resource.

Throws:

ConnectorRuntimeException

getPoolNameFromResourceJndiName

public PoolInfo getPoolNameFromResourceJndiName(ResourceInfo resourceInfo)

Gets the Pool name that this JDBC resource points to. In case of a PMF resource gets the pool name of the pool pointed to by jdbc resource being pointed to by the PMF resource

Specified by:

getPoolNameFromResourceJndiName in interface ConnectorRuntimeExtension

Parameters:

resourceInfo - the jndi name of the resource being used to get Connection from This resource can either be a pmf resource or a jdbc resource

Returns:

poolName of the pool that this resource directly/indirectly points to

isConnectionPoolReferredInServerInstance

public boolean isConnectionPoolReferredInServerInstance(PoolInfo poolInfo)

Determines if a JDBC connection pool is referred in a server-instance via resource-refs

Specified by:

isConnectionPoolReferredInServerInstance in interface ConnectorRuntimeExtension

Parameters:

poolInfo - pool-name

Returns:

boolean true if pool is referred in this server instance as well enabled, false otherwise

getResourceType

public String getResourceType(org.jvnet.hk2.config.ConfigBeanProxy cb)

Specified by:

getResourceType in interface ConnectorRuntimeExtension

getDeferredResourceConfig

public DeferredResourceConfig getDeferredResourceConfig(Object resource,
                                                        Object pool,
                                                        String resType,
                                                        String raName)
                                                 throws ConnectorRuntimeException

Specified by:

getDeferredResourceConfig in interface ConnectorRuntimeExtension

Throws:

ConnectorRuntimeException
