Custom Realm

[Meeraj Kunnumpurath]

Hi,

I have some specific requirements for security and I have been trying to
right a custom realm, that reads information from the database.

1. I have added a datasource in the global naming resources section in the
server.xml
2. I have packaged the realm class in a JAR file and copied it the server
lib
3. I have included a context.xml in the WAR META-INF, that declares the
realm from (2)

In the constructor of the realm class, I try to look up the datasource,

1. If I use new InitialContext().lookup, I get a name not found exception.
2. If I try to get the global naming context, by calling getServer from
RealBase, getServer returns a null reference.

This is the entry in server.xml

       <Resource name="MyDS"

              auth="Container"

              type="javax.sql.DataSource"

              driverClassName="oracle.jdbc.OracleDriver"

              factory="org.apache.tomcat.jdbc.pool.DataSourceFactory"

              url="jdbc:oracle:thin:@10.211.55.7:1521:xe"

              username="meeraj"

              password="password"

              maxTotal="20"

              maxIdle="10"

              maxWaitMillis="-1"

              accessToUnderlyingConnectionAllowed="true"/>

This is the entry in the context.xml

<Realm className="com.ss.security.provider.DatabaseRealm" digest="SHA1"/>

This is the constructor of the Realm class

    public DatabaseRealm() throws NamingException {
        Context context = null;
        try {
            context = new InitialContext();
            template = new SimpleJdbcTemplate((DataSource)
context.lookup("MyDS"));
        } finally {
            if (context != null) context.close();
        }
    }

Any pointers will be highly appreciated.

Many thanks
