Re: onException in camel

[Tarun Kumar <ag...@gmail.com>]

Hi Chrisrtian,

Thanks for the reply. Issue in my case was, handleException of
ExceptionHandler class had IOException as method parameter. I removed this
method parameter from handleException method and it worked.

I was wondering if there is any way to pass parameters to handleException
method bean call from

   onException(IOException.class).handled(true).bean(ExceptionHandler.class,
"handleException");
