Tomcat UserDatabase

[Robert Harper <ro...@iat-cti.com>]

Is there an accepted way for an application to directly access/manipulate the
tomcat-users.xml database? I would like to automate the process of adding users
from my servlet but I am having a hard time finding documentation/samples of how
to do this. It may just be that I don't know how to grant access to this
resource to my app. I have added a line like 

 

grant codeBase "file:${catalina.home}/webapps/my_appt/WEB-INF/classes/-" {

        permission java.security.AllPermission;

};

 

to the catalina.policy file. My code compiles but I get a 

 

java.lang.NoClassDefFoundError: org/apache/catalina/realm/UserDatabaseRealm 

 

error that I assume is due to an access restriction.

 

Any ideas? Thanks in advance.
