hi all,
I am running Axis beta 1 under Tomcat 4 on a Linux
Box.
I have a simple java application that has a method
called getResults that takes a String ("cityName"),
uses a SAXParser to parse an xml file, searches for
the element with that city name, and returns a string
with the contents for that city.
This code works fine when I run it from the command
line, but when I tried to place it under Axis and
access it as a web service, it gave me the following
stackTrace:
Exception in thread "main"
java.lang.reflect.InvocationTargetException

Anyone have any ideas why it won't run as a web
service?
Thanks for any help.
