grails – java. Lang. illegalaccesserror: attempt to access class XYZ from class ZXY

I have a Grails application. If I start it through it, it works normally

grails run-app

In the early stage, I have deployed the application to the Tomcat instance on the node without any problems However, yesterday I started preparing to produce everything and set up a stray box to deploy the whole stack A very strange thing happened suddenly:

I have a way

def checkEmail(String email)

In my registercontroller, it calls static methods

static String normalize(final String email) throws InvalidEmailAddressException

In a groovy class, it is placed under '/ SRC / groovy' in the corresponding package in my project

Whenever I call the checkemail method in the controller, I will see the following exception:

2014-04-07 20:19:20,588 [http-bio-8080-exec-6] ERROR errors.GrailsExceptionResolver  - IllegalAccessError occurred when processing request: [GET] /register/checkEmail

Invalidemailaddressexception is as follows and placed under '/ SRC / Java' in the corresponding package in the project:

package com.getgrape.core.exception;

class InvalidEmailAddressException extends Exception {

    private static final long serialVersionUID = 1L;

    InvalidEmailAddressException() {
        super();
    }

    InvalidEmailAddressException(String message) {
        super(message);
    }
}

I basically don't know what happened

>I checked for possible duplicate definitions of invalidemailaddressexception, but I couldn't find anything. > I tried to rename exception in case I ignored anything or it might conflict with another library, but it didn't help either. > I checked all the import statements, and they also looked good. > If I completely delete the call to the normalize method, the error disappears So, this must be something about the method, which throws an exception. > I tried to remove the static modifier from the method and call it by instantiating the object, but it made no difference. > I checked the war file to see if it contained invalidemailaddressexception and where it should be. > I tried to deploy the application to the Tomcat I just downloaded, but the problem still exists Therefore, it should not be a configuration problem. > No compiler errors

Who knows what might happen?

java version is: oracle jdk 1.7.0_51
grails: 2.3.7
running on ubuntu 12.04

War was established through "war", and I had been running "Grails clean all" before the war began

Solution

If there is no public modifier, this method is only applicable to the package of the class See http://docs.oracle.com/javase/tutorial/java/javaOO/accesscontrol.html. This applies to non - public exception classes Constructors and methods should also be public if you want global access
