Re: Custom exception page

[Steve Shucker]

Look at tapestry's ExceptionDisplay component source.  It uses something 
called an ExceptionAnalyzer and also displays the contents of the 
ExceptionDescription.getProperties().

I've got a custom exception page that writes to log4j.  Here's what I 
use to get the text:

   public void logException(Throwable value) {
       ExceptionAnalyzer analyzer = new ExceptionAnalyzer();
       ExceptionDescription[] exceptions = analyzer.analyze(value);
       setExceptions(exceptions);
       StringBuffer text = new StringBuffer();
       for (ExceptionDescription exception : exceptions) {
           text.append("Class: " + exception.getExceptionClassName() + 
"\n");
           text.append("Message: " + exception.getMessage() + "\n");
           for (ExceptionProperty property : exception.getProperties()) {
               text.append("Property: " + property.getName() + " = " + 
property.getValue() + "\n");
           }
       }
       String[] stack = exceptions[exceptions.length-1].getStackTrace();
       for (String stackItem : stack) {
           text.append(stackItem + "\n");
       }
       log.error(text.toString());
   }

Can anyone help me out with a snippet of code? On my Exception.html/.page I 
have a simple @Insert with getError(). Here's my code, but it doesn't provide a 
nice traceback :(


public String getError()
  {
    ExceptionDescription[] Errors = getExceptions();
    String err = "";
    
    for (int i = 0; i < Errors.length; i++)
      err += Errors[i].getMessage() + "<br>";

  return err;
}

Any ideas?

Thanks,
Greg
