Class ProgrammaticService

java.lang.Object

com.orchestranetworks.service.ProgrammaticService

public class ProgrammaticService
extends Object

This class provides the ability to programmatically log a user session. This allows executing procedures in a well-defined context, for example in a scheduled task or in a batch.

To run a procedure from a user service, it is recommended to use ServiceContext.execute(Procedure) instead of this class, unless input parameters have to be specified (e.g. to have a specific behavior in triggers).

Warning: When modifying permissions in this context (by importing an EBX® archive or merging a dataspace programmatically), the session cache must be cleared via a call to Session.clearCache(). Otherwise, these modifications will not be reflected in the following operations.

Using this class

In order to create an instance of this class, the external program must provide an authenticated session and a dataspace or snapshot:

 ProgrammaticService.createForSession(Session, AdaptationHome)
 

In order to update the repository for import or export of data, a Procedure.execute() method must be called in a transactional container via:

 ProgrammaticService.execute(Procedure)
 

Code sample

 public class MyBatch implements Batch {

 public void executeBatch(Repository aRepository) throws Exception {
                Session session = aRepository.createSessionFromLoginPassword("xxx", "yyy");
                AdaptationHome dataSpace = aRepository.lookupHome(BranchKey.forName("myBranch"));
                ProgrammaticService svc = ProgrammaticService.createForSession(session, dataSpace);
                // optional
                svc.setSessionTrackingInfo("My Script Sample");
                Procedure proc = new Procedure()
                {
                        public void execute(ProcedureContext aContext) throws Exception
                        {
                                // ...
                        }
                };
                ProcedureResult result = svc.execute(proc);
                if (result.hasFailed())
                // ...
                else
                //...
                }
 }
 }

Method Detail

createForSession

public static ProgrammaticService createForSession(Session aSession,
                                                   AdaptationHome aDataSpace)

Instantiates a service that will execute within the specified session in the specified dataspace.

createForSession

public static ProgrammaticService createForSession(Session aSession,
                                                   AdaptationHome aDataSpace,
                                                   Map<String,String> someInputParameters)

Instantiates a service that will be executed in the specified dataspace, and within a session cloned from aSession with specific input parameters.

This is the same as ProgrammaticService.createForSession(aSession.clone(someInputParameters), aDataSpace).

Session.clone(Map), Session.getInputParameterValue(boolean, String)

execute

public ProcedureResult execute(Procedure aProcedure)

Executes the specified procedure. It calls in a transactional container the implementation of Procedure.execute(ProcedureContext).

Returns:

the result of the execution (particularly, whether it has thrown an exception).

getCurrentHome

public AdaptationHome getCurrentHome()

Returns the current dataspace or snapshot of this service.

getSession

public Session getSession()

Returns the current session of this service.

setSessionTrackingInfo

public void setSessionTrackingInfo(String trackingInfo)

Specifies the session's tracking info.

Note: This method has a side-effect: if the underlying session is obtained through a user interface container (for instance UISessionContext.getSession()), this method can impact all future events of this session. In such cases, it is recommended to reset the tracking info to its previous value once the work has been done.
