Help: Custom Resource Factory Class

["Mateo A. Ortega" <pe...@yahoo.com>]

Hello,

I have been banging my head on this for two days, I am
guessing somebody else has done this successfully
(although searches in the archive & usenet come up
empty).

I am using Tomcat 4.0 and I am trying to use a
non-tyrex datasource.  According to the docs I have to
create my own ObjectFactory and modify the web.xml &
server.xml, but I keep getting 
"javax.naming.NamingException: Cannot create resource
instance".  

This was with Opta2K and a ObjectFactory I wrote.  I
noticed Micro$ has a beta version of Merant and it
includes SQLServerDataSourceFactory, so I put this
following in web.xml:
<resource-env-ref>
        <description>blah</description>
       
<resource-env-ref-name>jdbc/db</resource-env-ref-name>
       
<resource-env-ref-type>com.microsoft.jdbcx.sqlserver.SQLServerDataSourceFactory</resource-env-ref-type>
    </resource-env-ref>

And in server.xml I put:
<ResourceParams name="jdbc/db">
                <parameter>
                    <name>user</name>
                    <value>myuser</value>
                </parameter>
                <parameter>
                    <name>password</name>
                    <value>mypassword</value>
                </parameter>
                <parameter>
                    <name>serverName</name>
                    <value>127.0.0.1</value>
                </parameter>
                <parameter>
                    <name>databaseName</name>
                    <value>mydb</value>
                </parameter>
            </ResourceParams>

But I still get "javax.naming.NamingException: Cannot
create resource instance", when I do a lookup [I have
verified that the entry is there ("XmlMapper:
org.apache.catalina.core.StandardContext.addResourceEnvRef(
jdbc/db,
com.microsoft.jdbcx.sqlserver.SQLServerDataSourceFactory)"]
 

I have been able to connect to the db with both
drivers w/o a problem, but this is driving me crazy. 
Any help is appreciated.....tia
