Subject Problem getting DB connection
Date Tue, 12 Sep 2006 11:50:07 GMT
Hi we are working with JBoss 4.0.4.CR2 and trying to test some DBCP SQL 
connection using code that looks like
            Context jndiContext = getInitialContext();           
            String dataSourceJndiName = 
JndiNameProvider.getInstance().getDataSourceName(dataSourceName);
            DataSource dataSource = (DataSource) 
jndiContext.lookup(dataSourceJndiName);
            return dataSource.getConnection();

We have creates a test.war that contains:
Web-INF/classes <- our test classes
WEB-INF/lib <- the important cactus jars and all of the jars that make 
up our applications ear (which is deployed in the same jboss), including 
the classes being tested.
WEB-INF/jboss-web.xml that contains:
<?xml version="1.0" encoding="UTF-8"?>
<jboss-web>
    <resource-ref>
        <res-ref-name>OracleDS</res-ref-name>
        <res-type>javax.sql.DataSource</res-type>
        <jndi-name>java:/OracleDS</jndi-name>
    </resource-ref>
</jboss-web>

WEB-INF/web.xml that contains:

    <!-- JDBC DataSources (java:comp/env/jdbc) -->
    <resource-ref>
        <description>The default DS</description>
        <res-ref-name>OracleDS</res-ref-name>
        <res-type>javax.sql.DataSource</res-type>
        <res-auth>Container</res-auth>
    </resource-ref>

</web-app>

The res-ref stuff is our latest attempt but it doesn't seem to have 
helped as the problem has not changed.

The interesting thing is the four unittest functions that call code that 
does not access the DB work fine server side.  It's just the one that 
tries to get a connection that blows up as the line:
            DataSource dataSource = (DataSource) 
jndiContext.lookup(dataSourceJndiName);
returns null.

Any help would be greatly appreciated.

Thanks

Doug
