JBOSS jndi Datasource: jdbc not bound

Question

Im adding an jndi Datasource to JBOSS 4.0.2.
1. i copied jdbc driver to JBOSS_HOME/server/default/lib.
2. i copied following ds.xml to JBOSS_HOME/server/default/deploy (its based ony the mysql-ds.xml from the samples)
<?xml version="1.0" encoding="UTF-8"?>
<datasources>
  <local-tx-datasource>
    <jndi-name>jndi-name</jndi-name>
    <connection-url>jdbc:mysql://localhost:3306/databasename</connection-url>
    <driver-class>org.gjt.mm.mysql.Driver</driver-class>
    <user-name>username</user-name>
    <password>password</password>
    <exception-sorter-class-name>org.jboss.resource.adapter.jdbc.vendor.MySQLExceptionSorter</exception-sorter-class-name>
    <!-- sql to call when connection is created
    <new-connection-sql>some arbitrary sql</new-connection-sql>
      -->
    <!-- sql to call on an existing pooled connection when it is obtained from pool
    <check-valid-connection-sql>some arbitrary sql</check-valid-connection-sql>
      -->
    <!-- corresponding type-mapping in the standardjbosscmp-jdbc.xml (optional) -->
    <metadata>
       <type-mapping>mySQL</type-mapping>
    </metadata>
  </local-tx-datasource>
</datasources>I look this up using java:jndi-name. Works perfect.
For compatibility with other containers, i want to move my jndi-datasource to java:comp/env/jdbc/jndi-name
So i change my ds-description:
<?xml version="1.0" encoding="UTF-8"?>
<datasources>
  <local-tx-datasource>
    <jndi-name>comp/env/jdbc/jndi-name</jndi-name>
    <connection-url>jdbc:mysql://localhost:3306/databasename</connection-url>
    <driver-class>org.gjt.mm.mysql.Driver</driver-class>
    <user-name>username</user-name>
    <password>password</password>
    <exception-sorter-class-name>org.jboss.resource.adapter.jdbc.vendor.MySQLExceptionSorter</exception-sorter-class-name>
    <!-- sql to call when connection is created
    <new-connection-sql>some arbitrary sql</new-connection-sql>
      -->
    <!-- sql to call on an existing pooled connection when it is obtained from pool
    <check-valid-connection-sql>some arbitrary sql</check-valid-connection-sql>
      -->
    <!-- corresponding type-mapping in the standardjbosscmp-jdbc.xml (optional) -->
    <metadata>
       <type-mapping>mySQL</type-mapping>
    </metadata>
  </local-tx-datasource>
</datasources>Looking this up with java:comp/env/jdbc/jndi-name leads to Could not find datasource: java:comp/env/jdbc/jndi-name
javax.naming.NameNotFoundException: jdbc not bound
Some lines above jboss prints:
[WrapperDataSourceService] Bound connection factory for resource adapter for ConnectionManager 'jboss.jca:name=comp/env/jdbc/jndi-name,service=DataSourceBinding to JNDI name 'java:comp/env/jdbc/jndi-name
Please can somebody explain what the problem is about binding a datasource somewhere else than directly to "java:"

Answer 1

In web.xml making the following entry:
<web-app>
<description>MySQL Test App</description>
<resource-ref>
<description>DB Connection</description>
<res-ref-name>jdbc/test</res-ref-name>
<res-type>javax.sql.DataSource</res-type>
<res-auth>Container</res-auth>
</resource-ref>
</web-app>
Next, add a file jboss-web.xml under WEB-INF/ folder of the web-application. This file should contain entry as:
<jboss-web>
<resource-ref>
<description>DB Connection</description>
<res-ref-name>jdbc/test</res-ref-name>
<res-type>javax.sql.DataSource</res-type>
<jndi-name>java:/jdbc/test</jndi-name>
<res-auth>Container</res-auth>
</resource-ref>
</jboss-web>
Next, in JBOSS_HOME/server/default/deploy folder make a xx-ds.xml file or else, a similiar file can be found in that same folder with the name hsqldb-ds.xml. Make following entries in that xml file:
<datasources>
<local-tx-datasource>
<jndi-name>/jdbc/test</jndi-name>
<type-mapping>MySQL</type-mapping>
<connection-url>jdbc:mysql://localhost:3306/shopping_cart</connection-url>
<driver-class>com.mysql.jdbc.Driver</driver-class>
<user-name>root</user-name>
<password>root123</password>
<min-pool-size>1</min-pool-size>
<max-pool-size>5</max-pool-size>
</local-tx-datasource>
This should bind the jndi name.
In our client application, we need to look up as:
Context ctx = new InitialContext();
DataSource ds = (DataSource)ctx.lookup("java:/jdbc/test");
Connection conn = ds.getConnection();
This works perfectly.
