Question

Hi,
I have created a BPEL process having its own xsd schema file and i have also imported Task.xsd.In this process i want to invoke TaskManager Service in java Embed activity(bpel:exec language="java") in following manner:
/////////////////////////////////////////////////CODE////////////////////////////////////////////////
Task task = TaskFactory.createFacade(new QName("http://services.oracle.com/bpel/task", "task"));
task.setTitle("Task Title");
task.setCreator("ProcessManager...");
task.setAssignee("assignee");
task.setPriority(3);
NormalizedMessage nm = new NormalizedMessage();
nm.addPart("payload",task.getRootElement());
Locator locator = new Locator("default","bpel");
IDeliveryService deliveryService = (IDeliveryService)locator.lookupService(IDeliveryService.SERVICE_NAME );
deliveryService.post("TaskManager", "initiateTask", nm );
////////////////////////////////////CODE////////////////////////////////////////////////////////
It creates the instance of taskmanager but following error occur in its initiate task.
//////////////////////////////////ERROR/////////////////////////////////////////////////////////////
<IntiateFault xmlns="http://services.oracle.com/bpel/task">

The exception reported is: [POL-5134] invalid host variable type Please check that the machine hosting the datasource is physically connected to the network. Otherwise, check that the datasource connection parameters (user/password) is currently valid. sql statement: INSERT INTO task( domain_ref, conversation_id, title, creation_date, creator, modify_date, modifier, assignee, status, expired, exp_date, priority, template, custom_key, conclusion ) VALUES ( ?, ?, ?, ?, ?, ?, ?, ?, ?, ?, ?, ?, ?, ?, ? )</summary>

By default the BPEL 10.1.2, it will do a local call to the process. It will not execute a SOAP request, no network access is done.
It can be configured at domain level:
Parameter: optSoapShortcut (SOAP local optimization)
Turns on "short-cut" for local SOAP request; local SOAP calls are normally done via an internal call instead of sending a message through the SOAP stack.
The default behavior for the engine is to optimize all. To disable optimization specify a value other than "true" or "yes".
