Hi Rex,
thanks for your answer. But this, I think, is the problem. My EAR
consits
out of 40 EJB's and 25 WAR's and all are using the @Resource
injection for
the database. Til now I don't have descriptors for the EJB's (no
"ejb-jar.xml") - I thought they are no longer neccessary in JEE5.
And the
deployment descriptors of the WAR's ("web.xml") only contains the
servlet-mappings. (This EAR file can successfully deployed in JBoss
and in
GlassFish without modifications.)
To be able to deploy this in Geronimo do I really need to add 40 new
"openejb-jar.xml", 40 new "ejb-jar.xml" and 25 new "geronimo-
web.xml" files
- and also change 25 "web.xml" files to place the
tag? Is
there no way to just use injection without specifying it in all
descriptors?
Maybe there is a way to define a jdbc resource globally in Geronimo
to use
in with injection?
I think you should be able to avoid geronimo plans for each module.
You need to
1. make sure that the name specified in the annotations or dd resource-
ref is the same as the datasource name you specify when you deploy the
connection pool.
2. make the connection pool "visible" to your application by adding
its id as a dependency to the geronimo plan for your application.
This should be enough to make the auto-map work.
hope this helps

Frank

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": jdbc/MyDataSource javax.sql.DataSource Container Shareable Also this page tell me to insert the following code into the "geronimo-web.xml" file: MyWebApp console.dbpool jdbc___mes /MyWebApp jdbc/MyDataSource jdbc/__mes 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: mes.suite console.dbpool jdbc___mes 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: jdbc/__mes javax.sql.DataSource Container Shareable 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?

So... - deploy a datasource e.g. using the console and note what the artifact name is for the resulting plugin - add a dependency on that datasource plugin into the ear or ejb plan (geronimo-application.xml or openejb-jar.xml) As long as the name in the @Resource annotation matches the name in the connector plan that's all that's necessary. thanks david jencks Thanks in advance for an answer, greetings, Frank -- View this message in context: http://www.nabble.com/%22Could-not-auto-map-to-resource%22-problem-when-using-EJB-annotations-only-tp23316686s134p23316686.html Sent from the Apache Geronimo - Users mailing list archive at Nabble.com.
