Java exception handling

[temp temp]

    For good  exceptional handling  should I create  all my methods in try 
catch block and throw  exception in the catch block with e.printstacktrace()
       
      Exammple
       
                  public void processQueryResults(Map  metaInfo, Map 
entityInfo) throws WorkflowException {
                               try{
                                           if(entities==null){
                                                       entities=  new 
ArrayList();
                                           }
                                           IEntityDAO  entityDAO  
=ObjectFinder.getEntityDAOFromBpAlias(StringUtilities.stripNamespace(metaInfo.get(IWorkflow.BUSINESS_PROCESS_ALIAS).toString()));
                                           Entity  entity=entityDAO.createNew();
                                           Integer  entityId=new 
Integer(metaInfo.get(IWorkflow.ENTITY).toString());
                                           entity.setId(entityId.intValue());
                                           entity.fromMap(entityInfo);
                                           entity.setMetaInfo(metaInfo);
                                           entities.add(entity);
                               }catch(Exception  e)      {
                                           e.printStackTrace();
                                           throw new  WorkflowException(e);
                               }
                  }
  Is this good way to handle exception ?
  Thanks & Regards
