Date Wed, 19 Jun 2002 08:33:57 GMT
I put jdbc driver in all directories, in "regular directory" and in jar
file. In Tomcat 3.2 it worked, not in 4.0.

Tomcat probably isn't finding your jdbc driver.  The exception's
getMessage() method is returning a class name, which usually means
ClassNotFoundException or ClassCastException.  Read this:

Hello,

I've got a problem with Tomcat 4.0 (Catalina). After setting up REALM:

<Realm  className="org.apache.catalina.realm.JDBCRealm" debug="99"
             driverName="org.gjt.mm.mysql.Driver"

connectionURL="jdbc:mysql://localhost/authority?user=test&amp;password=test"
              userTable="users" userNameCol="user_name"
userCredCol="user_pass"
          userRoleTable="user_roles" roleNameCol="role_name" />

I can not connect to mysql server which is running on localhost. The error I
received is:

Catalina.start:Lifecycle Exception: Exception opening database connection:
java.sql.SQLException: org.gjt.mm.mysql.Driver

I ran through many faq's lists and the only solution I found was: check
tables, all names etc. I've checked not twice but ten times receiving the
same type of error.

I use FORM type of authentication. Everything was ok with Tomcat 3.2 and got
worse after installing new version of Tomcat. Libraries: org.jar,
servlet.jar are added to classpath.

I would be grateful for any help.

Pawel
