trying to compile and run java through the terminal
Hey everybody,

Ok here is my problem. I have this code that that compiles, but when i go to run it it gives me errors.

I stored my simple java class here:
/user/workspace/getMailFromSafeDoc/src

I store my mail.jar file here:
/user/workspace/getMailFromSafeDoc/lib/javaMail/javaMail.jar

In my terminal i go to that folder and i compile it by:
javac -classpath ../lib/javaMail/javaMail.jar javaMail.java

..... this works and products a class file with no errors.

when i go to complile it by:
java javaMail

i get:
Exception in thread "main" java.lang.NoClassDefFoundError:
Exception in thread "main" java.lang.NoClassDefFoundError: javax/mail/NoSuchProviderException
Caused by: java.lang.ClassNotFoundException: javax.mail.NoSuchProviderException

at sun.misc.Launcher$AppClassLoader.loadClass(Launcher.java:294)
at java.lang.ClassLoader.loadClass(ClassLoader.java:268)
at java.lang.ClassLoader.loadClassInternal(ClassLoader.java:336)


When i take out all the try and catch, it works fine.


Here is my code:

Code:
import javax.mail.*;
public class getMail 

{
    
private String userName;
    
private String userPassword;
    
private String mailServer;
    
public getMail(String inputUserName, String inputPassword, String inputMailServer)
    
{
        
    userName = inputUserName;
    
    userPassword = inputPassword;
    
    mailServer =inputMailServer;
    
    processMail(userName, userPassword, mailServer);
    
}
    
    

public static void main(String[] args) 

{
        
// TODO Auto-generated method stub
        
//System.out.println("Hi");
        
getMail getSafedocMail = new getMail("dcm", "dcm01", "mail.safedoc.ie");
    
}
    
    
    


private void printData(String inputString)
    
{   
    System.out.println(inputString);   
}
    
    
    


private void processMail(String inputUserName, String inputPassword, String inputMailServer)
    
{
    
    Session session = null;
    
    Store store = null;
    
    printData("-------------connecting to mail-----------------");
        
    session = Session.getDefaultInstance(System.getProperties(), null);
    

    try 
        
    {
            

        store = session.getStore("pop3");
        
    } 
        
    catch (NoSuchProviderException e) 
    
    {
    
        e.printStackTrace();
    
    }
    
}


Any idea lads?
