Java Web Server 6.1 & Pooled SQL Server 2000 JDBC Connections

msmamet (Programmer)

f anyone can shed some light on this problem I would greatly appreciate it.

I am unsuccessfully trying to use a database connnection retrieved from a pool configured using Java System Web Server 6.1 with the SQL Server 2000 JDBC Driver.

The background:
1. I have downloaded the SQL Server 2000 JDBC Driver and installed it on the web server.
2. I used the Administration GUI to add the .jars(namely msbase.jar, msutil.jar, and mssqlserver.jar), to the classpath.
3. Upon creating a simply JSP to access connection metadata using the direct connect method, ie.,

Class.forName( com.microsoft.jdbc.sqlserver.SQLServerDriver);
Connection con = DriverManager.getConnection( "jdbc:microsoft:sqlserver:// ....

I am shown a successful output.

Now the fun begins...
In order to set up the JDBC Connection Pool I have done the following...
1. I have created a web.xml file for the web-app which contains the JSP and includes the following entry
<resource-ref>
<res-ref-name>jdbc/devjwscp</res-ref-name>
<res-type>javax.sql.DataSource</res-type>
<res-auth>Container</res-auth>
</resource-ref>
2. I have used the "JDBC Connection Pools" link under the "Java" tab in the Administration GUI to create a connection pool.
"Pool Name:" is "devjwscp"
"DataSource Classname" is set to "com.microsoft.jdbcx.sqlserver.SQLServerDataSource". All other properties have been left alone.
3. I have used the "JDBC Resources" link under the "Java" tab in the Administration GUI to create a JNDI resource.
"JNDI Name" is set to "jdbc/devjwscp"
"Status" is "true"
"Pool Name" is "devjwscp"
The web-app JSP comes back with the following exception.
JDBC Test
Exception Thrown
Cannot create resource instance
javax.naming.NamingException: Cannot create resource instanceorg.apache.naming.factory.ResourceFactory.getObjectInstance(ResourceFactory.java:167)
javax.naming.spi.NamingManager.getObjectInstance(NamingManager.java:301)
org.apache.naming.NamingContext.lookup(NamingContext.java:834)
org.apache.naming.NamingContext.lookup(NamingContext.java:181)

4. FYI my server.xml <RESOURCE> entry looks as is shown below
<RESOURCES>
<JDBCCONNECTIONPOOL name="devjwscp" datasourceclassname="com.microsoft.jdbcx.sqlserver.SQLServerDataSource" steadypoolsize="8" maxpoolsize="32" poolresizequantity="2" idletimeout="300" maxwaittime="60000" connectionvalidationrequired="off" connectionvalidationmethod="auto-commit" validationtablename="" failallconnections="off" transactionisolationlevel="read-uncommitted" isolationlevelguaranteed="off">
<PROPERTY name="serverName" value="secret"/>
<PROPERTY name="portNumber" value="1433"/>
<PROPERTY name="User" value="secret"/>
<PROPERTY name="Password" value="secret"/>
</JDBCCONNECTIONPOOL>
<JDBCRESOURCE jndiname="jdbc/devjwscp" poolname="devjwscp" enabled="on"/>
</RESOURCES>

What gives? Do I need to add anything else to the server.xml? I know the server.xml for JWS differs from Apache. I have done an exhaustive search of the web. Many other individuals have had the same thing happen, buy none of them offered any explaination or remedy.

Thanks in advance.
