thread local - Spring and ThreadLocal -

i have spring web app. whenever in app, there error, put error in error context (code given below). then, retrieve error in exception handler , return message. now, input a, if error message "person not there" now, first call spring web app, right output: "person not there" however, second call: output : "person not there" , "person not there" thus, remembers last request though using threadlocal. can please help

my errorcontext code:

public class errorcontext {

private static threadlocal<errorcontext> thisobj = new threadlocal<errorcontext>();  /**  * list of errors.  */ private arraylist<applicationerror> errorlist;  /**  * default private constructor.  */ private errorcontext() {     errorlist = new arraylist<applicationerror>(); }  /**  * initialize threadlocal variable.  */ public static void initialize() {     if (thisobj.get() == null)         thisobj.set(new errorcontext());     else {         errorcontext errorcontext = (errorcontext) thisobj.get();         if (errorcontext.geterrors() != null)             errorcontext.geterrors().clear();      } }  /**  * returns new instance of class.  *  * @return {@link errorcontext}.  */ public static errorcontext getinstance() {     if (thisobj.get() == null) {         thisobj.set(new errorcontext());     }     return (errorcontext) thisobj.get(); }  /**  * add error code list.  *  * @param errorcode  *            errorcode obtained.  */ public void adderror(final applicationerror error) {     errorlist.add(error); }  /**  * return list of errorcodes.  *  * @return list of error codes.  */ public list<applicationerror> geterrors() {     return errorlist; }  /**  * @author anbapri resets context.  */ public static void resetcontext() {     thisobj.set(new errorcontext());     errorcontext errorcontext = (errorcontext) thisobj.get();     if (errorcontext.geterrors() != null)         errorcontext.geterrors().clear(); }  /**  * returns true if errorcontext has error, otherwise false.  *  * @return  */ public boolean haserror() {     return !errorlist.isempty(); } 

}

my response handler {
package com.db.wscis.core.web.handler;

import java.util.arraylist; import java.util.list; import java.util.locale;

@controlleradvice public class restexceptionprocessor {

} }

the way fix errorcontext.resetcontext() after end of exception handler.
