Obtaining a List of Features with the License Manager

Declare Variables/Constants

String  CONTACT_SERVER = "localhost";
 
String ScopeFeatureInfoPart1 = "<?xml version=\"1.0\" encoding=\"UTF-8\"?> "+

 				"<sentinelScope>"+ 
				 "<feature index=\"";
String ScopeFeatureInfoPart2 = "\"><name></name>"+
    			       "<version></version>"+
     			       "</feature>"+
			       "</sentinelScope>";
int iRetCode = LicensingConstants.SNTL_SUCCESS;
int iFeatureIndex = 0;
Attribute attrAppContext = null;
ApplicationContext appContext = null;

API Calls

To obtain features list, execute the APIs in the specified sequential order only:

>attrAppContext = new Attribute();

>attrAppContext.set(LicensingConstants.SNTL_ATTR_APPCONTEXT_CONTACT_SERVER, CONTACT_SERVER);

NOTE   If instead the LSFORCEHOST or LSHOST environment variables are set, then the above-mentioned steps are not required.

>appContext = new ApplicationContext(attrAppContext);

>Now call appContext.getInfo inside a while loop (incrementing the feature index, iFeatureIndex at each iteration, its initial value being 0), till the return code is SNTL_NO_MORE_FEATURES, as shown in the code snippet below:

try   
   {
      
      Attribute attrAppContext = new Attribute();
      attrAppContext.set(LicensingConstants.SNTL_ATTR_APPCONTEXT_CONTACT_SERVER, CONTACT_SERVER);
      ApplicationContext appContext = new ApplicationContext(attrAppContext);

      while(iRetCode != LicensingConstants.SNTL_NO_MORE_FEATURES) {
		  StringBuffer buff = new StringBuffer(ScopeFeatureInfoPart1);
		  buff.append(iFeatureIndex++);
		  buff.append(ScopeFeatureInfoPart2);
		  String ScopeFeatureInfo = buff.toString();
		  String featureInfo = appContext.getInfo(ScopeFeatureInfo,       
		  LicensingConstants.SNTL_QUERY_FEATURE_INFO_VERSION("1.0"));
		/* Parse the XML output contained in featureInfo */
		}/*end of while loop*/
      
      attrAppContext.dispose();
      appContext.dispose();
   }
   catch(java.io.UnsupportedEncodingException e) 
   {
      System.out.println(e.getMessage());
   }
   catch(LicensingException e) 
   {
	if (e.getStatusCode() != (int) LicensingConstants.SNTL_NO_MORE_FEATURES) 
	{
		System.out.println("Got an exception : " + e);
		System.out.println("Status Message : \n" + e.getMessage());
	}
	else 
	{
		System.out.println("Reached end of enumeration...no more features");
	}
   }
   finally{
      LicensingAPI.cleanup();
      }
   }

On success during each iteration of the while loop, the featureInfo string contains an XML-based output having the detailed information.
