Subject RE: Irregular error dumped to stderr without a stack trace.
Date Fri, 26 Sep 2003 17:58:39 GMT
Yoav,

If that were the case the report should bomb out every time it was ran on
the same set of data - which its not :(

There is a catch in the base servlet that should throw a stack trace for ANY
error.
After some more debugging, the exception is being caught by this base
Exception catch (identified by a System.out) - but like I said, the
stacktrace is being truncated to the first line of it for some reason.
Normally this would provide a full stack trace.

Steve

Howdy,
Do you use System.out/System.err to log in your app?

Could it simply be an uncaught null pointer exception in your report
generation code due to some bad data contents in the report?
