JDBCRealms in Tomcat 4
Hi,
just to make things sure in the beginning, my problem is not to get JDBCRealms to work ;) My Problem is to get several of them up and running - if it is possible.
Im using Tomcat 4 with mod_webapp through Apache. Everything works fine. But i need several JDBCRealms for different servlets. The only place where i could get the JDBCRealm to work is in the Tomcat-Apache <service>-Entry in the server.xml.
Though, there is just on Tomcat-Apache-Service, but several servlets. So i guess there must be a way to define the JDBCRealm Servlet-specific out of this Service-Entry. In former times - running Tomcat 3 - i put the JDBCRealm into the web.xml in the webapp-dir of the regarding servlet. Though - Tomcat 4 ignores any Realm i put there.
So, where can i define a Servlet-Specific Realm how ?
regards,
Cedric

Ok, thanks, that's it. There are days where you better leave the Server alone ;) My problems depend on the Fact that i don't have any Context defined ;)

I have tried to setup a realm and in server.xml of Tomcat 4, I wrote:
...
<Realm className="org.apache.catalina.realm.JDBCRealm" debug="99"
driverName="COM.ibm.db2.jdbc.app.DB2Driver"
connectionURL="jdbc:db2:CRISAN"
connectionName="crisan"
connectionPassword="parola"
userTable="users" userNameCol="user_name"
userCredCol="user_pass"
userRoleTable="users_roles" roleNameCol="role_name" />
...
to configure the Realm.
Every table is corectly created in db2 but when i try to start Tomcat, I get the following error:
"Starting service Tomcat-Standalone
Apache Tomcat/4.0.3

If you have the answer to mine, I would appreciate your help or any suggestion.
A million thankx in advance,
Sincerly,
