Join Workspace with API fails

Question

Hi
Need advice with setting the options for workflow when requesting to join workspace from webservices API provided. What workflow Options or Attributes should i established in NamedValue?
I have tried retrieving workflow configurations through this API:
Item[] wfItems = m_WFM.getWorkflowConfigurations(curItem.getId(),wfreq1);
// with Attributes.WORKFLOW_PARAMETERS & Attributes.WORKFLOW_OPERATIONS
The result is NULL.
I am able to retrieve Ids of 2 workspaces that are joinable.
User requested role is of type FdkConstants.ROLEKEY_AUTHOR
Code snippet to Join WorkSpace:
NamedValue[] wfoptions = new NamedValue[1];
NamedValue nv1 = new NamedValue();
nv1.setName(Attributes.WORKFLOW_PARAMETERS);
nv1.setValue(null);
wfoptions[0] = nv1;
long id = curItem.getId();
System.out.println("current id =="+id);
Item it = m_WM.joinWorkspace(id,requestedRole,wfoptions,areq);
long wsId = it.getId();
and the error received:
faultCode: {http://schemas.xmlsoap.org/soap/envelope/}Server.userException
faultSubcode:
faultString: ORACLE.FDK.WorkflowError:ORACLE.FDK.WorkflowParameterInvalid
faultActor:

Please try with the following change
wfoptions = new NamedValue[]
new NamedValue("IFS_ECM_WORKFLOW_JUSTIFICATION", "justification")
