For example, change a user's firstname in Chinese and submit, the info will be changed to unreadable charactors and stored in db. I added this line in the very beginning in CASAuthenticationValve.invoke and fixed the problem: request.setCharacterEncoding("UTF-8"); Perhaps there are other ways to overcome this problem. If not, it would be better to add such a line to the source code. Regards, Shi Yusen/Beijing Langhua Ltd. View the original post : http://www.jboss.org/index.html?module=bb&op=viewtopic&p=4224464#...
