This is how we do it in a spring app, with a resourcelink in context.xml
conf/server.xml
<GlobalNamingResources>
<Resource auth="Container"
driverClassName="oracle.jdbc.OracleDriver"
maxActive="10"
maxIdle="5"
maxWait="10000"
name="jdbc/oraclePool"
username="myuser"
password="notapassword"
type="javax.sql.DataSource"
url="jdbc:oracle:thin:@myhost.acme.com:1521:TEST"
/>
</GlobalNamingResources>
META-INF/context.xml
<?xml version="1.0" encoding="UTF-8"?>
<Context>
<ResourceLink name="jdbc/oraclePool" type="javax.sql.DataSource"
global="jdbc/oraclePool"/>
</Context>
WEB-INF/applicationContext.xml
<bean id="dataSource"
class="org.springframework.jndi.JndiObjectFactoryBean">
<property name="jndiName" value="jdbc/oraclePool" />
<property name="resourceRef" value="true" />
</bean>

Subject: How to configure JNDI resource
Hi all,
I've a question about how to configure a datasource to be accessed via
JNDI.
I have a datasource configured in server.xml (In
Server/GlobalNamingResources/Resource).
In the documentation
http://tomcat.apache.org/tomcat-6.0-doc/config/context.html#Resource_Def
initions
it says that that a resource/datasource can be declared in the context
element of a webapp like this:
<Context ...>
...
<Resource name="jdbc/EmployeeDB" auth="Container"
type="javax.sql.DataSource"
description="Employees Database for HR Applications"/>
...
</Context>
Also it is written that it is possible to declare a resource inside
web.xml:
<resource-ref>
<description>Employees Database for HR Applications</description>
<res-ref-name>jdbc/EmployeeDB</res-ref-name>
<res-ref-type>javax.sql.DataSource</res-ref-type>
<res-auth>Container</res-auth>
</resource-ref>
My question is:
1) is it enough to declare the needed resource inside web.xml or
2) do I have to declare it also in the context element for accessing it
via JNDI?
And, if 2) is correct what is the use to declare a resouce in the
webapps web.xml when it has been already declared in the context element
of the webapp?
Regards,
Abid
