Hi David,

thanks a lot for your explanation. I've tried to deploy it, as you
described, but it didn't work.

I don't know where my mistake is. I've tried it in the following way:

1. Using the WebConsole, I've created a database pool using the database
pool wizard. The name of the pool is "jdbc/__mes". The database is
accessible successfully (test-db-ping works).

2. Now the database pool with the name "jdbc/__mes" is listed in the
"Database Pools" page in Geronimos WebConosle. If I follow the link "Usage"
for this pool, I see a lot of hints how to use this pool - but I can't bring
it to work.

3. The "Usage" page tell me to include the following section into my
"web.xml":
 <resource-ref>
    <res-ref-name>jdbc/MyDataSource</res-ref-name>
    <res-type>javax.sql.DataSource</res-type>
    <res-auth>Container</res-auth>
    <res-sharing-scope>Shareable</res-sharing-scope>
  </resource-ref>
Also this page tell me to insert the following code into the
"geronimo-web.xml" file:
 <environment>
        <moduleId>
            <artifactId>MyWebApp</artifactId>
        </moduleId>
        <dependencies>
            <dependency>
                <groupId>console.dbpool</groupId>
                <artifactId>jdbc___mes</artifactId>
            </dependency>
        </dependencies>
    </environment>
    <context-root>/MyWebApp</context-root>
    <resource-ref>
        <ref-name>jdbc/MyDataSource</ref-name>
        <resource-link>jdbc/__mes</resource-link>
    </resource-ref>

As fas as I understand you, it is not neccessary to do this in the web.xml
and geronimo-web.xml files. Instead I may define this in the
geronimo-web.xml.
As you wrote, I've tried to use add a dependency in the
geronimo-application.xml - this is the result:
<?xml version="1.0" encoding="UTF-8"?>
<application>
  <environment>
    <moduleId>
      <artifactId>mes.suite</artifactId>
    </moduleId>
    <dependencies>
      <dependency>
        <groupId>console.dbpool</groupId>
        <artifactId>jdbc___mes</artifactId>
      </dependency>
    </dependencies>
  </environment>
</application>

The @Resource annotation has a "name" this attribute: "jdbc/__mes".

But I still got this deployment error. Also I've tried to insert the
following section in the geronimo-application.xml, but it didn't help:

<resource-ref>
    <res-ref-name>jdbc/__mes</res-ref-name>
    <res-type>javax.sql.DataSource</res-type>
    <res-auth>Container</res-auth>
    <res-sharing-scope>Shareable</res-sharing-scope>
</resource-ref>

I don't know, what my mistake is.

Do I need to add something to the "application.xml"?
What do I need to add to the "geronimo-web.xml" to make jdbc connection
available for all web and ejb modules included in the ear?

Thanks,
 Frank
