Question

Hi All,
    I am getting the exception "Exception: java.lang.RuntimeException: Caller doesn't have enough permission to call this method.", when i try to execute the code  "Composite MFTComposite = (Composite)locator.lookupComposite(compositeNameRevision); ".Below mentioned the sample code , i am using this code for getting the running instances.
try{   
          String componentInstanceID = new Long(getInstanceId()).toString();   
          addAuditTrailEntry("Component Instance ID is "+componentInstanceID);   
          Locator locator = LocatorFactory.createLocator();   
          addAuditTrailEntry("Created locator..");   
         String compositeRevision = (String)getVariableData("compositeRevision"); 
addAuditTrailEntry("compositeRevision..1111"+compositeRevision);   
          String compositeNameRevision = "ManagedFileTransfer/MFT!" + compositeRevision;
          Composite MFTComposite = (Composite)locator.lookupComposite(compositeNameRevision);  
          addAuditTrailEntry("MFT Composite lookup complete..setting filter");   
          CompositeInstanceFilter filter = new CompositeInstanceFilter();   
          filter.setState(CompositeInstance.STATE_RUNNING);  
          filter.setTitle((String) getVariableData("transferName"));  
          List<CompositeInstance> instances = MFTComposite.getInstances(filter);   
          StringBuffer message = new StringBuffer();  
          if ((instances != null) && (instances.size() > 1)) {   
              addAuditTrailEntry("currently running MFT Instances..");   
              for (CompositeInstance instance : instances) {   
                message.append("Instance: " + instance.getId() + " Creation date: " + instance.getCreationDate() + ",");        
                addAuditTrailEntry("Instance: " + instance.getId() +   
                             " creation-date: " + instance.getCreationDate());  
          setVariableData("runningInstance", message.toString());    
        } catch (Exception ex) {   
            setVariableData("runningInstance", ex.getMessage());  
            addAuditTrailEntry("Exception: " + ex);   
Appreaciate your quick response.

Hi Vamsi.P,
Try something like below... Using weblogic admin credentials...
Hashtable props = new Hashtable();
props.put(Context.SECURITY_PRINCIPAL,   "fred");
props.put(Context.SECURITY_CREDENTIALS, "seafood");
Locator locator = LocatorFactory.createLocator(props);  
Cheers,
