HI,
I have a project written in java springs. When i run the file containing the main method  i am getting the following error :
Exception in thread "Main Thread" java.lang.ClassFormatError: javax/mail/MessagingException : Missing Code attribute
      at java.lang.ClassLoader.defineClass1(Native Method)


-----------File----------------------
package com.yatra.extremesearch.app;

import org.apache.log4j.Logger;
import org.springframework.context.support.ClassPathXmlApplicationContext;



public class ExtremeSearchApp {
      private static final Logger logger = Logger.getLogger(ExtremeSearchApp.class);
      
      public static void main(String args[]){
            
             try {
                   logger.info("=====Starting Extreme search======");
                   new ClassPathXmlApplicationContext("classpath*:spring/root-context.xml");
                  
                  } catch (Exception e) {
                        logger.error(e.getMessage());
                  }
            }
}

Unable to find out the reason for it.

Thanks

Seems to be one of your libraries . ClassFormatError is thrown when the JVM cannot interpret a class file . Can you replace the java mail jar and see.

Hi,
What should i replace the mail.jar with ?
If i remove it i get the error :
The archive: /libs/jars/java/mail.jar which is referenced by the classpath, does not exist.

How do i make my code run ? I dont need to test whether the mailling functionallity is working or not.
Can i just remove the need of mail.jar ?

Please advice how to do it.

Thanks

Well , if you don't want to test email , then you will have to remove references to mail.jar from within your code too.
When I suggested you to replace mail.jar , I meant that it should be replaced with another version , maybe a newer version . What version are you using currently?
