javax.naming.NameNotFoundException: Name jdbc is not bound in this Context

Posted by Roger Keays, 15 April 2008, 2:11 PM

It seems that Tomcat 5.5 and 6.0 DataSourceRealms don't like referring to JNDI resources declared in the same context. The following configuration gives me a javax.naming.NameNotFoundException:

<Context path="/">
  
  <!-- connection pool for database -->
  <Resource name="jdbc/data" auth="Container" type="javax.sql.DataSource"
            driverClassName="org.postgresql.Driver"
            url="jdbc:postgresql://localhost/test"
            username="postgres" password=""
            maxActive="5" maxIdle="2" maxWait="-1"/>

  <!-- authentication realm -->
  <Realm className="org.apache.catalina.realm.DataSourceRealm"
         dataSourceName="jdbc/data" digest="MD5"
         userTable="web_users" userRoleTable="web_user_roles"
         userNameCol="id" userCredCol="password" roleNameCol="role"/>
</Context>

However, if I move the JNDI resource up it works as expected:

<GlobalNamingResources>

  <!-- connection pool for database -->
  <Resource name="jdbc/data" auth="Container" type="javax.sql.DataSource"
            driverClassName="org.postgresql.Driver"
            url="jdbc:postgresql://localhost/test"
            username="postgres" password=""
            maxActive="5" maxIdle="2" maxWait="-1"/>
</GlobalNamingResources>
...
<Context path="/">
        
  <!-- authentication realm -->
  <Realm className="org.apache.catalina.realm.DataSourceRealm"
         dataSourceName="jdbc/data" digest="MD5"
         userTable="web_users" userRoleTable="web_user_roles"
         userNameCol="id" userCredCol="password" roleNameCol="role"/>
</Context>

Odd...

@see tomcat-users:

Yes. If you want a realm to use a context defined datasource rather than a global one you need to set: localDataSource="true" on the realm

It is documented in the howto but not the realm docs. I'll fix that now. http://tomcat.apache.org/tomcat-6.0-doc/realm-howto.html#DataSourceRealm

grrr...
