spring not able to find JNDI data source

Question

I am developing a spring web application . A JAR file which I use in my application , is looking for DataSource using JNDI. I configured the element in my tomcat's server.xml. The configuration is as below ,

<GlobalNamingResources> <Resource name="jdbc/abcd" auth="Container" type="javax.sql.DataSource" maxActive="70" maxWait="10000" username="xxxx" password="yyyy" validationQuery="SELECT 1 from dual" driverClassName="oracle.jdbc.driver.OracleDriver" url="jdbc:oracle:thin:@xx.xxx.xx.xx:xxxx:zzzz" testOnBorrow="false" testOnReturn="false" testWhileIdle="true" timeBetweenEvictionRunsMillis="120000" minEvictableIdleTimeMillis="3600000" /> </GlobalNamingResources>

The Resource name configured above , "jdbc/abcd" is the same which the JAR is looking for, But its not able to find this configured data source . Does anyone know what could be the reason ?

Am getting the below exception ,

javax.naming.NameNotFoundException: Name jdbc is not bound in this Context

Can you provide the application context, where you lookup your datasource — Omnaest

am not getting your question . actually am new to web application development . Can you tell what do you mean by 'application context' ? — Mariselvam

The Spring Framework defines a container area which is called "application context". Thats e.g. a XML file called "application-context.xml" which has Bean definitions within. This part of the Spring Documentation will give you more details. — Omnaest

I don't think Spring or Spring configuration is the problem here. He is using an external jar file that seems to have a dependency to a J2EE resource named jdbc/abcd. What he need to do is defining this resource in the J2EE context for his application. I don't think the Spring application context is relevant. — sstendal

No, "jdbc/abcd" is shorthand for the JNDI name. It should be "java:comp/env/jdbc/adbc" for Tomcat. — duffymo

You need to define a ResourceLink in the web application context that makes the global resource visible to the web application.

<ResourceLink name="nameThatIsVisibleToTheWebApplication" global="theGlobalName" ...

should I put this in web.xml ?

@Mariselvam You can put it into the context.xml file which is located in the /conf folder where the server.xml resides,too.

You need to do more than just configure Spring.

I'd recommend reading Tomcat JNDI documentation and this.
