Hello,
My environment is:
JBoss-3.0.2+Tomcat-4.0.4 (integrated)
JDK 1.4
Win2000
I am trying to access a datasource from a web app, using this code:
Context ctx = new InitialContext();
DataSource ds = ( DataSource )ctx.lookup( "java:comp/env/jdbc/DeptFuncDS" );
However, I get the
javax.naming.NamingException: Could not dereference object [Root exception is java.lang.NullPointerException].
What is the problem? If there is an error, what is a correct way to lookup a data source from a web-app?
My jboss-web.xml:
<?xml version="1.0"?>
<jboss-web>
<resource-ref>
<resource-ref-name>jdbc/DeptFuncDS</resource-ref-name>
<jndi-name>java:/OkeanTestDS</jndi-name>
</resource-ref>
</jboss-web>
Note: java:/OkeanTestDS works correctly with CMP EJBs.
Snip from the web.xml:
<?xml version="1.0"?>
<web-app>
..
<resource-ref>
<res-ref-name>jdbc/DeptFuncDS</res-ref-name>
<res-type>javax.sql.DataSource</res-type>
<res-auth>Container</res-auth>
<res-sharing-scope>Sharable</res-sharing-scope>
</resource-ref>
..
</web-app>
