How to Get Business or object Specific Attribute by code

Hi All,

I want to find the available Attribute List and its respective Values for WTDocument.

I am able to find System and General Attributes and its Respective values by below code,

I got code to fetch Attributes and its values on PTC portal, but when i use this in my code, i got below error.

Here in my case, "OI_BUSINESS_TYPE" is soft type Attribute of String data type.

Here is my code,

public static void main(String[] args) throws WTException, RemoteException{

  RemoteMethodServer rms = RemoteMethodServer.getDefault();

  GatewayAuthenticator auth = new GatewayAuthenticator();

  auth.setRemoteUser("wcadmin");

  rms.setAuthenticator(auth);

  String docnumber="0000000264";

  WTDocument wtdoc=null;

  // search condition

  QuerySpec qs = new QuerySpec(WTDocument.class);

  SearchCondition sc = new SearchCondition(WTDocument.class,WTDocument.NUMBER,SearchCondition.EQUAL,docnumber,true);

  qs.appendSearchCondition(sc);

  QueryResult qr = PersistenceHelper.manager.find(qs);

  System.out.println(">> Qr size == "+qr.size());

  while(qr.hasMoreElements()){

  wtdoc=(WTDocument)qr.nextElement();

  //System and General Attribute values like created by, Name , version , Lifecycle State etc are simple to get its values as like below.

  System.out.println(">>> Name "+wtdoc.getName());

  System.out.println(">>>>Number  "+wtdoc.getNumber());

  System.out.println(">>>> Creator "+wtdoc.getCreatorName());

  System.out.println("***** "+wtdoc.BUSINESS_TYPE.toString());

  System.out.println(">>>>> "+wtdoc.getIdentity());

  System.out.println(">>>Life Cycle State "+wtdoc.getState());

  System.out.println(">>> description "+wtdoc.getDescription());

  // Code /Api need to Find Attribute and its values found on PTC portal .

  com.ptc.core.lwc.server.LWCNormalizedObject obj = new com.ptc.core.lwc.server.LWCNormalizedObject(wtdoc,null, java.util.Locale.US, new com.ptc.core.meta.common.DisplayOperationIdentifier());

  /* Get value of IBAName soft attribute */

  obj.load("OI_BUSINESS_TYPE"); 

  java.lang.String string_value = (java.lang.String) obj.get("OI_BUSINESS_TYPE");   

  System.out.println("Soft attibute value : " + string_value);

  }

  System.out.println("Done..");

  }
