Defining resources in deployment descriptor

[teg79]

My application is composed by a war and some ejb-jar

The web app has its own jboss-web.xml with the datasource resource-ref definition:

<jboss-web>

    <resource-ref>

        <res-ref-name>app/myDatasource</res-ref-name>

        <jndi-name>java:/oracle/myDatasource</jndi-name>

    </resource-ref>

</jboss-web>

I need to define the same deployment descriptor for the ejb-jars, searching the forum I found that I have to use the jboss-ejb3.xml but I cannot find the documentation or any example defining the resource-ref element in this file.

Can someone point me to some example?

Hmm, not sure, there is something in the metadata project: https://github.com/jboss/metadata/tree/master/ejb/src/main/resources/schema

Thanks for the link, this is my jboss-ejb3.xml:

<?xml version="1.1" encoding="UTF-8"?>

<jboss:ejb-jar xmlns:jboss="http://www.jboss.com/xml/ns/javaee"

               xmlns="http://java.sun.com/xml/ns/javaee"

               xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"

               xmlns:c="urn:clustering:1.0"

               xsi:schemaLocation="http://www.jboss.com/xml/ns/javaee http://www.jboss.org/j2ee/schema/jboss-ejb3-2_0.xsd http://java.sun.com/xml/ns/javaee http://java.sun.com/xml/ns/javaee/ejb-jar_3_1.xsd"

               version="3.1"

               impl-version="2.0">

    <resource-ref>

        <res-ref-name>app/myDatasource</res-ref-name>

        <jndi-name>java:/oracle/myDatasource</jndi-name>

    </resource-ref>

</jboss:ejb-jar>

But this is not working... the error is

How is the datasource defined in standalone.xml?

[teg79]

Here the standalone.xml fragment:

                <datasource jta="true" jndi-name="java:/oracle/myDatasource" pool-name="MyOracleDS" enabled="true" use-java-context="true" use-ccm="true">

                    <connection-url>jdbc:oracle:thin:@server:1521:SID</connection-url>

                    <driver>oracle</driver>

                    <pool>

                        <max-pool-size>1</max-pool-size>

                    </pool>

                    <security>

                        <user-name>USER</user-name>

                        <password>PWD</password>

                    </security>

                </datasource>

Not sure you can have a resoure-ref dangling around like that without it being in e.g. a session bean definition.

Here is another thread on the matter: https://community.jboss.org/message/718466
