>          Components: Core Engine

>     exception.printStackTrace(new PrintWriter(stringWriter));
>     this.exception = stringWriter.toString();

> a exception is thrown if the exception has more than 4000 characters (at least with Oracle). This code can be fixed easyly:
>   public void setException(Throwable exception) {
>     StringWriter stringWriter = new StringWriter();
>     exception.printStackTrace(new PrintWriter(stringWriter));
>     String st = stringWriter.toString();
>     
>     // perhaps can not write more tha 4000 chars to database field (e.g. Oracle)
>     if (st.length()>4000) 
>     	st = st.substring(0, 4000);
>     this.exception = st;
>   }
> By the way, this is already done correctly in Timers (Timer.java) :-) Perhaps some refactoring to centralize thi issue would be nice (for example a String getExceptionAsString(Throwble t) helper-method).
>         if (t!=null) {
>           log.error("unhandled timer exception", t);
>           // this means an unhandled exception occurred in this timer
>           StringWriter sw = new StringWriter();
>           actionException.printStackTrace(new PrintWriter(sw));
>           exception = sw.toString();
>           if (exception.length()>4000) exception = exception.substring(0, 4000);
>         }
