Problem with JBoss and DataSource

[gabry86]

Hi!!

I've a problem. i'm developing an application with Google Web Toolkit run on server JBoss 4.2.2. I'm using a DataSource, and it´s good. The problem is that i modify the file web.xml to add the datasource:

<?xml version="1.0" encoding="UTF-8"?>
<web-app version="2.5" xmlns="http://java.sun.com/xml/ns/javaee" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://java.sun.com/xml/ns/javaee http://java.sun.com/xml/ns/javaee/web-app_2_5.xsd">

Conecta con la BD oracle
<servlet-name>ComunicaBD</servlet-name>
<servlet-class>org.yournamehere.server.ComunicaBDImpl</servlet-class>

<servlet-mapping>
<servlet-name>ComunicaBD</servlet-name>
<url-pattern>/ComunicaBD</url-pattern>
</servlet-mapping>
<session-config>
<session-timeout>
30
</session-timeout>
</session-config>
<welcome-file-list>
<welcome-file>welcomeGWT.html</welcome-file>
</welcome-file-list>
<jboss-web>
<context-root>Asignacion</context-root>
</jboss-web>
<resource-ref>
<res-ref-name>portalDS</res-ref-name>
<res-type>javax.sql.DataSource</res-type>
<res-auth>Container</res-auth>
</resource-ref>
</web-app>

the lines in bold are new. If i remove this lines, the aplication runs, but if i put it, the server don't executes the aplication. This is wrong??

Help and Thanks

The issue is that once you place a resource-ref into web.xml, then the app expects to find the resource in the local naming context (java:/comp/env/portalDS). But you need to tell JBoss AS to map the name back to the java: namespace. To do that, place an entry for the datasource in WEB-INF/jboss-web.xml:

<jboss-web>
 <resource-ref>
 <res-ref-name>portalDS</res-ref-name>
 <jndi-name>java:portalDS</jndi-name>
 </resource-ref>
</jboss-web>

Also, please use 'code' tags around your XML text - select the text and click the Code button above the editor window.
