I put the taglibs-mailer.tld into the right place and after inspecting this file I found the uri above should be correct. I have javamail 1.3 and java beans activation package installed and set classpath properly. But this exception always showed up when I open the jsp file:
is it because I didn't set the mail server properly? (I didn't, just entered some value like "asdf") I guess if this is the case, I should get some information like "mail server not available" but why there's something to do with the authenticatior? I am really . Any suggestion or explaination would be highly appreciated.
It's up to you where you stick the JavaMail JAR(s) but I reckon that should solve your problem.

following your suggestion, I simply pasted mail.jar and activation.jar into the folder mail-app/WEB-INF/lib, rebooted tomcat and reload the page, now the customized error page displaying "Please enter the correct mail server address" appeared. Thank you very much!
