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.
