RE: [OFF-TOPIC] - RE: How to capture the ROOT cause of EXCEPTION

[Bodycombe, Andrew]

You could try this:

try 
{ 
 ... 
} 
catch(Exception e) 
{ 
    Throwable cause = e.getCause(); 
    if (cause != null)
        cause.printStackTrace();
    else
        System.err.println("ROOT CAUSE is null");
}

Hi all, 

I tried out the following code but it did not work. 

try 
{ 
 ... 
} 
catch(Exception e) 
       { 
      Throwable cause = e.getCause(); 
       System.out.println(e.getCause()); 
       } 

Can anyone help. 

Thanks, 
Vikas.

Hi, 
Did you try: 

try 
{ 
  ... do something... 
} 
catch(Exception e) 
{ 
  Throwable cause = e.getCause(); 
  ... do whatever you want with the cause ... 
} 

By the way, as this is not a tomcat question, please either post 
somewhere appropriate (comp.lang.java.help for example), or at least add 
OFF-TOPIC to your subject.  Thanks,
