Subject Re: error with xtags and tomcat 3.3
Date Sat, 10 Nov 2001 13:11:54 GMT
Hi James,

I still believe there is something broken between dom4j-full.jar (v1.1) and
the latest xtags build (the one you just updated, the nov 10 build).  I
uncompressed the examples and are running them unmodified on tomcat 3.3 with
jdk 1.3.01 and the only classes in my application classpath are
dom4j-full.jar and xtags.jar.  Some of the examples work, for example, the
simple rss example and the stock quote example.  However, the periodic_table
and much_ado examples both give an exception (shown below), and
periodic_table2 shows every element as having 112 atoms.  Any suggestions?
Thanks!

-Richard
