If possible, I'd move all of those except for the postgresql driver into your web application's WEB-INF/lib folder. We can move them back if absolutely necessary. Is "mail.jar" the JavaMail API/implementation? You'd only need that in Tomcat's lib/ directory if you were asking Tomcat to provide mail session via JNDI -- such would appear somewhere in either your web applications' META-INF/context.xml file or some file under CATALINA_BASE/conf/* Check your version of JavaMail. There are older versions which contain vulnerabilities that have been patched. The API is (AFAICT) 100% backward-compatible, so you should be able to upgrade to JavaMail.latest without any problems.

Tomcat should refuse to load classes over-top of the standard java.*, javax.*, and a few other top-level packages but it's always possible something might sneak in there and confuse everything. > -rw-r-----. 1 root root 474746 Jan 11 15:05 > postgresql-8.3-603.jdbc4.jar> -rw-r-----. 1 root root 355030 Jan > 11 15:05 mail.jar If you have either (or both) of these in Tomcat's CATALINA_BASE/lib or CATALINA_HOME/lib directories, you'll want to remove them from here. > -rw-r-----. 1 root root 352668 Jan 11 15:05 log4j-1.2.8.jar Ok. > -rw-r-----. 1 root root 55008 Jan 11 15:05 local-ldap-0.0.1.jar > -rw-r-----. 1 root root 38114 Jan 11 15:05 ldap-src-0.0.1.jar > -rw-r-----. 1 root root 38668 Jan 11 15:05 ldap.jar -rw-r-----. 1 > root root 55827 Jan 11 15:05 ldap-0.0.1.jar Hmm.

Other than adding those 4 JAR files (and dropping your webapp into CATALINA_BASE/webapps), did you do anything else to Tomcat since you installed it? Any configuration file changes? - -chris -----BEGIN PGP SIGNATURE----- Comment: GPGTools - http://gpgtools.org Comment: Using GnuPG with Thunderbird - http://www.enigmail.net/ iQJRBAEBCAA7FiEEMmKgYcQvxMe7tcJcHPApP6U8pFgFAlpX510dHGNocmlzQGNo cmlzdG9waGVyc2NodWx0ei5uZXQACgkQHPApP6U8pFi0PRAAqwxatbXr1Z7TXrjL M5qcaTqG0TP+4qKh/PgqAIDbzcU9bgrIieF7ZaaUiNDuE56KqPM5MQfzA9SEChce 0M8n/XqzfOItntFDWR7/QSbFGvtDGs8bdxetmXSKEb6u19dHrHY6E65//1blr4hB fLFECsSsnHVnVo0NILdn15Y/wFUohU9BfabKYk7CAGXMGJiGi8gzHB8RGgB4Mz1H +DegRSlGV3MYXBJMULqU94DTNN47CQ7VYmKrOLSnlxsY7YfXYSxyVpwW+J4JiTm6 9qiG0V2aFWs3lWvig3MMWDTSatz5BaqOHA5eJJUHvdhSjcPRCmZFOjCkm5yv/RBl zrbErWIYyaYytwuTUy4tE8v3hdj0Wg2sC5Sm5yZgIfWep1S9AkVKhibalaz4DvZ+ B22mFnxoWEApxExbICjxHuAksKsXqG0Z5GibjRBp7MvAkiK/i+h4XOQ0eLXL5VGD 7XH5cFpj+8OALiqOX5DKqZnCJtHJyscVUmMmeqY09FhaGm2HStrJ1PLVkFSanw1k xe93mPugCIOOK0mmoosVNwyZKj7je4TqaEd6Bulxx4R1l9A14jzFD3bzjyhPX08H XkGbNBXgGuBsbTteGQiO0XmR3HckhIkz+/dudVdXRKB5nFZ6CZ+d4zO4Kc/MXccq SNJwVBvrCPSfpDhmqkpZ3CLwLjo= =bPa5 -----END PGP SIGNATURE----- --------------------------------------------------------------------- To unsubscribe, e-mail: users-unsubscr...@tomcat.apache.org For additional commands, e-mail: users-h...@tomcat.apache.org
