hi all thanks for the reply; things getting a litter clear. when i remove the jar file 'antlr-2.7.5H3.jar' , it work fine, put 0 in and get 0 out. but when i put the jar file back, it still put 0 in and get 1 out.
the jar is in the \tomcat\webapps\'myproject'\WEB-INF\lib\ it seems like the there is something wrong in the jar file.this jar is shipped with hibernate. And i try the newest jar file from the newest hiberbate,but it is still has the same problem. does anyone has a idea? the test code in a jsp file in my project: java.util.List alist =new java.util.ArrayList<Integer>(); alist.add(0); out.print(alist.get(0)); Regards On 5/22/07, Christopher Schultz <[EMAIL PROTECTED]> wrote:

Generics + autoboxing ought to allow you to put ints into an ArrayList (at least syntactically, though it's really just syntactic sugar). - -chris -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.4.7 (MingW32) Comment: Using GnuPG with Mozilla - http://enigmail.mozdev.org iD8DBQFGUhdv9CaO5/Lv0PARAmKMAJ9DjxpSf4zZmIdM+WQx8+q0fSRf7ACgjTAl MBXxUu/ld4Aanpt9gQ8IXGg= =38QU -----END PGP SIGNATURE----- --------------------------------------------------------------------- To start a new topic, e-mail: users@tomcat.apache.org To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]
