What is JNDI example?
A name that is bound within a context is the JNDI name of the object. In Specifying a Resource Reference, for example, the JNDI name for the JDBC resource (or data source) is jdbc/ejbTutorialDB . Much like a directory in a file system, a subcontext is a context within a context.
Why do we use JNDI?
JNDI is also defined independent of any specific naming or directory service implementation. It enables applications to access different, possibly multiple, naming and directory services using a common API. Different naming and directory service providers can be plugged in seamlessly behind this common API.
How do I know my JNDI name?

What does JNDI lookup method do?
The Java Naming and Directory Interface (JNDI) is a Java API for a directory service that allows Java software clients to discover and look up data and resources (in the form of Java objects) via a name. connecting a Java application to an external directory service (such as an address database or an LDAP server)
How do you create a JNDI?
These three steps to configure and run a JNDI Datasource Connection pool for any Java Web application:
- Configure data source in Server and create JNDI name.
- Configure web.xml.
- Configure Spring bean with JNDI Datasource.
- Include JDBC driver library on Server lib e.g. tomcat/lib.
What is the full form of JDBC?
Java™ database connectivity (JDBC) is the JavaSoft specification of a standard application programming interface (API) that allows Java programs to access database management systems.
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.
What is Java comp?
java:comp/env is the node in the JNDI tree where you can find properties for the current Java EE component (a webapp, or an EJB). Context envContext = (Context)initContext.lookup(“java:comp/env”); allows defining a variable pointing directly to this node.
What is JNDI in Web technology?
The Java Naming and Directory Interface™ (JNDI) is an application programming interface (API) that provides naming and directory functionality to applications written using the Java™ programming language. It is defined to be independent of any specific directory service implementation.
What is InitialContext in Java?
The initial context implements the Context interface and provides the starting point for resolution of names. When the initial context is constructed, its environment is initialized with properties defined in the environment parameter passed to the constructor, and in any application resource files.
What is JNDI in J2EE?
JNDI is an application programming interface (API) for accessing different kinds of naming and directory services. J2EE components locate objects by invoking the JNDI lookup method.
What is the difference between JNDI and JDBC?
Well these are two different things. 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.
What does JNDI stand for?
JNDI stands for Java Naming and Directory Interface (Sun) Suggest new definition. This definition appears very frequently and is found in the following Acronym Finder categories: Information technology (IT) and computers.
What is the JNDI name for a DataSource?
JNDI names are usually defined like so: java:comp/env/jdbc/unblu – in the datasource name here we only need the jdbc/unblu part). Two properties (as above) must also be enabled for the ‘Admin’ connection.
What is the difference between JNDI and JDBC? JDBC is java database API, while JNDI is java native directory API. The main thing in here is that in a JNDI directory you’re actually storing a JDBC DataSource, so, you’re simply using JDBC and obtain a Connection via JNDI lookup.
What is JNDI in Java?
The Java Naming and Directory Interface (JNDI) is a Java API for a directory service that allows Java software clients to discover and look up data and resources (in the form of Java objects) via a name. Like all Java APIs that interface with host systems, JNDI is independent of the underlying implementation.
