Why JNDI is used in Java?

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. Thus a variety of directories -new, emerging, and already deployed can be accessed in a common way.

What is difference between JNDI and JDBC?

Answer: JDBC is java database API, while JNDI is java native directory API. In short words: JDBC is a Database realm, JNDI lets you store Objects in a virtual context (the Directory) that can be local, remote (Implementation details usually don’t matters).

Why do we use JNDI?

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 the difference between MQ and JMS?

MQ can act as a native queue mechanism or a transport for JMS messages. The difference being that JMS messages have some standard header fields at the begining of the message buffer and “native” mq messages contain just the data your program sent to the buffer.

Is JMS an API?

What Is the JMS API? The Java Message Service is a Java API that allows applications to create, send, receive, and read messages.

What do you need to know about WebLogic JNDI?

The following sections describe programming with WebLogic JNDI including: The WebLogic Server JNDI Service Provider Interface (SPI) provides an InitialContext implementation that allows remote Java clients to connect to WebLogic Server.

How is JNDI used in a clustered environment?

Using WebLogic JNDI in a Clustered Environment. The intent of WebLogic JNDI is to provide a naming service for J2EE services, specifically EJB, RMI, and Java Messaging Service (JMS). Therefore, it is important to understand the implications of binding an object to the JNDI tree in a clustered environment.

How does the JNDI service provider interface work?

The WebLogic Server JNDI Service Provider Interface (SPI) provides an InitialContext implementation that allows remote Java clients to connect to WebLogic Server. The client can specify standard JNDI environment properties that identify a particular WebLogic Server deployment and related connection properties for logging in to WebLogic Server.

How does WebLogic JMS work with Java EE?

WebLogic JMS is tightly integrated into the WebLogic Server platform, enabling you to build highly secure Java EE applications that can be easily monitored and administered through the WebLogic Server console.
