Error in handlinh web service

Question

Hello,
I created a web service in which, i am calling a procedure from oracle apps.
I am passing 3 values to procedure and getting one as a flag (Y or N) and other is null.
So while handling null value i am getting error as :
java.lang.nullpointer.........
I am posting my code here.
public ArrayList getApprove(int notification_id, String note, String username){
ArrayList error=new ArrayList();
con=getEBSConnection();
try {
cst= con.prepareCall("{call INOTIFICATION_PKG.approve_notification(?,?,?,?,?)}");
cst.setInt(1,notification_id);
cst.setString(2,note);
cst.setString(3,username);
cst.registerOutParameter(4,Types.VARCHAR);
cst.registerOutParameter(5,Types.VARCHAR);
cst.execute();
error.add(cst.getString(4));
String error_handle=cst.getString(5);
if(error_handle.equals(null)){
error_handle="Sucessfull";
error.add(error_handle);
else{
error.add(cst.getString(5));
} catch (SQLException e) {
System.out.println("No Such Record");
return(error);
