Method Detail

getTransportManager

public static TransportManager getTransportManager()
                                            throws TransportException

Returns:

Returns an instance of Transport Manager.

Throws:

TransportException

isAdmin

public static boolean isAdmin()

Returns:

Returns whether or not the code is being executed on the admin server

clusterExists

public static boolean clusterExists()

Returns:

true if ALSB is deployed in a WLS clustered domain

getUsernamePasswordCredential

public static weblogic.security.UsernameAndPassword getUsernamePasswordCredential(TransportProvider provider,
                                                                                  Ref serviceAccount)
                                                                           throws CredentialNotFoundException

Deprecated. Use getUsernamePassword(com.bea.wli.sb.transports.TransportProvider, com.bea.wli.config.Ref) instead

Parameters:

provider - transport provider

serviceAccount - a reference to a service account

Returns:

the username and password assigned to the service account. Transport providers that need access to credentials during activation can use this interface to lookup a username/password assigned to a service account. This interface should not be used to lookup credentials during outbound messaging

Throws:

CredentialNotFoundException - if the service account does not exist or if a username/password has not been assigned to the service account

getUsernamePassword

public static UsernamePassword getUsernamePassword(TransportProvider provider,
                                                   Ref serviceAccount)
                                            throws CredentialNotFoundException

Parameters:

provider - transport provider

serviceAccount - a reference to a service account

Returns:

the username and password assigned to the service account. Transport providers that need access to credentials during activation can use this interface to lookup a username/password assigned to a service account. This interface should not be used to lookup credentials during outbound messaging

Throws:

CredentialNotFoundException - if the service account does not exist or if a username/password has not been assigned to the service account

isStaticServiceAccount

public static boolean isStaticServiceAccount(Ref serviceAccount)
                                      throws TransportException

Parameters:

serviceAccount - a service account reference

Returns:

true if the service account is a static service account

Throws:

TransportException - if there is no service account for the given reference

getServiceInfo

public static ServiceInfo getServiceInfo(Ref ref)
                                  throws TransportException

Parameters:

ref - service reference

Returns:

service information, i.e. binding, transport configuration, etc. for corresponding service

Throws:

TransportException

searchInstanceIds

public static List<Ref> searchInstanceIds(String typeId,
                                          String keyName,
                                          Object keyValue)
                                   throws TransportException

Returns a list of references for instances that has the given keyValue for the given key. Can be used by transport providers to search for all services that match a certain search criteria.

Parameters:

keyName - can be one of the defined type ids, e.g. Refs.PROXY_REF. Also see Refs

keyValue - can be one of the defined queries, e.g. ProxyServiceQuery.KEY_PROXYURI. Also see ProxyServiceQuery and BusinessServiceQuery

Returns:

a list of references for instances that has the given keyValue for the given key. Returns empty list if none found.

Throws:

TransportException

schedule

public static void schedule(Runnable runnable,
                            String dispatchPolicy)
                     throws TransportException

Schedule a work instance for execution in another thread associated with specified dispatch policy. This method can be used by transport providers to post the results of outbound blocking message call back to ALSB response pipeline on a different thread than that on which the incoming request method was received. Dispatch policies can be configured with WLS console by the way of registering new Work Managers in the domain. If dispatchPolicy argument is null, the default dispatch policy will be used. Other semantics: o Runnable.run() will be called in the context of the security subject, if any, that was present at the time schedule() was invoked.

Parameters:

runnable - action to execute asynchronously

dispatchPolicy - name of the WLS WorkManager which will be used to execute the Runnable.run action. Maybe null, in which case the default work manager will be used.

Throws:

TransportException

getDispatchPolicies

public static Set<String> getDispatchPolicies()
                                       throws TransportException

Returns:

list of all available dispatch policies in ALSB domain

Throws:

TransportException
