New Tomcat 4 DataSourceRealm

[Glenn Nielsen <gl...@mail.more.net>]

A while ago Craig and I had discussed some new Realm implementations.

Here is a new Realm implementation which uses a database provided by
a JNDI named JDBC DataSource.

The current JDBCRealm uses a single db connection where user authentication
is synchronized.  This could be a bottleneck for sites which have heavy
usage of realm based applications with large numbers of users in the realm.

By using a DataSource its implementation (DBCP) manages a db connection pool.
This allows the DataSourceRealm to authenticate multiple users at the same time.

I have the new DataSourceRealm and updated Tomcat 4 documentation ready to commit.

Any objections to adding this?

Regards,

Glenn
