CF8 with JBoss JNDI datasource

Question

After installing and configuring a CF8 for J2EE running on
JBoss 4.2.2.GA with Java 6, I have created a JNDI datasource for
Oracle 10g in the oracle-ds.xml file. I have configured a CF8
datasource that uses the JNDI resource.
Any query that is NOT using cfqueryparam works quite well.
As soon as cfqueryparam is used, I get an "Error casting an
object of type org.jboss.resource.adapter.jdbc.WrappedConnection
cannot be cast to coldfusion.server.j2ee.sql.JRunConnectionHandle
to an incompatible type.".
The configuration and the exception is pretty much the same
as described in
Problem
description.
This is clearly a CF8 bug and I was wondering if there is any
known workaround for it.

Answer 1

In web.xml making the following entry:
<web-app>
<description>MySQL Test App</description>
<resource-ref>
<description>DB Connection</description>
<res-ref-name>jdbc/test</res-ref-name>
<res-type>javax.sql.DataSource</res-type>
<res-auth>Container</res-auth>
</resource-ref>
</web-app>
Next, add a file jboss-web.xml under WEB-INF/ folder of the web-application. This file should contain entry as:
<jboss-web>
<resource-ref>
<description>DB Connection</description>
<res-ref-name>jdbc/test</res-ref-name>
<res-type>javax.sql.DataSource</res-type>
<jndi-name>java:/jdbc/test</jndi-name>
<res-auth>Container</res-auth>
</resource-ref>
</jboss-web>
Next, in JBOSS_HOME/server/default/deploy folder make a xx-ds.xml file or else, a similiar file can be found in that same folder with the name hsqldb-ds.xml. Make following entries in that xml file:
<datasources>
<local-tx-datasource>
<jndi-name>/jdbc/test</jndi-name>
<type-mapping>MySQL</type-mapping>
<connection-url>jdbc:mysql://localhost:3306/shopping_cart</connection-url>
<driver-class>com.mysql.jdbc.Driver</driver-class>
<user-name>root</user-name>
<password>root123</password>
<min-pool-size>1</min-pool-size>
<max-pool-size>5</max-pool-size>
</local-tx-datasource>
This should bind the jndi name.
In our client application, we need to look up as:
Context ctx = new InitialContext();
DataSource ds = (DataSource)ctx.lookup("java:/jdbc/test");
Connection conn = ds.getConnection();
This works perfectly.
