Help! Problem of XUpdate(Xindice)

[Ren, Ziheng]

Hi,

i have already found a xindice based java gui. but it appears always a big
problem from the xupdate functions. If i tip some commands in and try to
execute them, it will appear an exception, this result from the example
http://xml.apache.org/xindice/guide-developer.html#N1025F are
extraordinarily similar:

i have also tested another gui(from
http://titanium.dstc.edu.au/xml/xmldbgui/screenshots.shtml) in different
versions of jre. but it appears the same problem. i'm not sure, whether it's
my problem or has xindice made sth wrong...

Thank you for your friendly help.
