Subject Re: error with xtags and tomcat 3.3
Date Sun, 11 Nov 2001 14:08:42 GMT
My fault- the example that crashed had its corresponding xml file referenced
absolutely instead of relatively, and I had the examples in a subdirectory
whic broke the absolute path.  I guess when i saw the period-table example
show 112 atoms for every element i just figured that one of the libraries
was broken.

Sorry for the confusion and thanks for your help!

Best regards,

Richard
