Hi,

I cannot succeed to use the Tomcat 5.0.24 admin console to manage my
UserDatabaseRealm (conf/tomcat-users.xml file). No UserDatabase is seen and
when I click to Users, I get the following error:
HTTP Status 500 - Error retrieving attribute users.
Thank you in advance for any help.
best regards,
