I mean user database, wich contains user/role configuration specially for my application, with no changes of global user database at TOMCAT/conf/users.xml.
If you're using JNDI Datasource.. As I know, this problem is ordinarry for Tomcat/JDBC/JNDI bundle. Try Google for "Cannot create JDBC driver of class '' for connect URL 'null'", it should help =)
I'm running application under Tomcat/5.4.4 and sometimes it (Tomcat) crashes - the process just simply disappears. I suppose there must be JVM error, but I don't know where i can find log. Does anybody know?
I think the problem is java.sql.Date, which designed to store Date info, but not Time. That also means it's .toString() method will return "yyyy-mm-dd". Try to use Timestamp instead, or use PreparedStatement.setDate(1, yourJavaSqlDateVariable).
