What is difference between JNDI and jdbc?

JDBC is Java Database Connectivity API, while JNDI is Java Naming and Directory Interface API. The main thing here is that in a JNDI directory you’re actually storing a JDBC DataSource, so, you’re simply using JDBC to obtain a Connection via JNDI lookup.

Why is JNDI required?

The Java Naming and Directory Interface (JNDI) provides consistent use of naming and/or directory services as a Java API. This interface can be used for binding objects, looking up or querying objects, as well as detecting changes on the same objects.

How does Tomcat define DataSource?

What is DataSource and JNDI?

A JNDI DataSource object is a file that contains the configuration details necessary to connect to a database. The DataSource object must be registered on a JNDI server, where it is identified using a JNDI name. You can register your DataSource object directly on your application server via its JNDI service.

Why JNDI is used in Java?

What is JNDI and LDAP?

Tomcat specific resource configuration is performed using the following elements in the element:

Can I write my own resource factory in Tomcat?

If none of the standard resource factories meet your needs, you can write your own factory and integrate it into Tomcat, and then configure the use of this factory in the element for the web application.

How does Tomcat support Java EE DataSource?

The Java EE Platform Specification requires Java EE Application Servers to make available a DataSource implementation (that is, a connection pool for JDBC connections) for this purpose. Tomcat offers exactly the same support, so that database-based applications you develop on Tomcat using this service will run unchanged on any Java EE server.

How do I create a JNDI resource in Tomcat?

Providing that Tomcat is able to identify an appropriate resource factory to use to create the resource and that no further configuration information is required, Tomcat will use the information in /WEB-INF/web.xml to create the resource. Tomcat provides a number of Tomcat specific options for JNDI resources that cannot be specified in web.xml.
