I want to get field label from a fieldSet. I have given below my component code where i want to display fieldSet Labels only. 

    <apex:component controller="LeftBarComponentController">   
        <apex:pageBlock >
          <apex:pageblocksection title="Personal Information">  
                    <apex:repeat value="{!fields}" var="f">                 
                        <apex:outputText value="{!con[f.label]}">                    
                        </apex:outputText>                    
                    </apex:repeat>  
                </apex:pageblocksection>
       </apex:pageBlock>
    </apex:component> 

My controller code is as follows - 

    public Application__c con{get;set;}
    //User cid = [Select id,ContactId from User where id =:UserInfo.getUserId()];
    String  ids ='003J00000057btk';
    Id tempId = ids;
    Contact AppId = [select AppId__c from Contact where id=:tempId ];
    

    public LeftBarComponentController(){
        this.con = getApplicationDetails();
    }
 
     public List<schema.fieldsetmember> getFields() {  
        return SObjectType.Application__c.FieldSets.ApplicationStatusFieldset.getFields();  
    }  
    
    public Application__c getApplicationDetails() { 
        String query = 'SELECT ';  
        for(Schema.FieldSetMember f : this.getFields()) {  
            query += f.getFieldPath() + ', ' ;  
            query += f.getLabel() + ', ' ; 
        }  
        query = query+'Id FROM Application__c where id =\''+AppId.AppId__c +'\'' ;
        return Database.query(query);  
    } 

When i try to run the component i am getting following error -
