What is JNDI in Tomcat?

Tomcat provides a JNDI InitialContext implementation instance for each web application running under it, in a manner that is compatible with those provided by a Java Enterprise Edition application server. The Java EE standard provides a standard set of elements in the /WEB-INF/web.

What is JNDI in Tomcat?

Tomcat provides a JNDI InitialContext implementation instance for each web application running under it, in a manner that is compatible with those provided by a Java Enterprise Edition application server. The Java EE standard provides a standard set of elements in the /WEB-INF/web.

What is a JNDI connection?

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 JNDI connection pool?

A connection pool improves performance and scalability by allowing multiple clients to share a small number of physical connections. You set up the connection pool in your application server and access it through Java Naming and Directory Interface (JNDI).

What is JNDI in Java with examples?

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 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.

Why do we use JNDI?

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.

Is JNDI obsolete?

Though you can use a direct JNDI name, this naming method is deprecated in Version 6 of WebSphere® Application Server (WAS).

What is LDAP JNDI?

LDAP is a standard way to provide access to directory information. JNDI gives Java applications and objects a powerful and transparent interface to access directory services like LDAP.

Where is JNDI used?

Typical uses of JNDI include: connecting a Java application to an external directory service (such as an address database or an LDAP server) allowing a Java Servlet to look up configuration information provided by the hosting web container.

What is difference between JNDI and DataSource?

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 is the difference between Java SE and Java EE?

SE is a normal Java Specification. It consists of class libraries, virtual machines, deployment environment programming. Java EE is a structured application with separate Client, Business, Enterprise layers. Mostly used to develop APIs for Desktop Applications like antivirus software, game etc.

Does LDAP use JNDI?

So where does JNDI fit into this LDAP jargon? JNDI does for LDAP what JDBC does for Oracle — it provides a standard API for interacting with naming and directory services using a service provider interface (SPI), which is analogous to an JDBC driver. LDAP is a standard way to provide access to directory information.

How to connect to a PostGIS database using JNDI?

GeoServer can also connect to a PostGIS database using JNDI (Java Naming and Directory Interface). To begin, navigate to Stores ‣ Add a new store ‣ PostGIS NG (JNDI). Name of the workspace to contain the store. This will also be the prefix of all of the layer names created from the store.

How do I add PostGIS to GeoServer?

PostGIS is an open source spatial database based on PostgreSQL, and is currently one of the most popular open source spatial databases today. Adding a PostGIS database ¶ As with all formats, adding a shapefile to GeoServer involves adding a new store to the existing Stores through the Web administration interface. Using default connection ¶

How do I configure the JNDI datastore in GeoServer?

Login into the GeoServer web administration interface and configure the datastore. First, choose the Oracle (JNDI) datastore and give it a name: Then, configure the connection parameters so that the JNDI path matches the one specified in the Tomcat configuration:

How to configure the JNDI pool in Tomcat?

For configuring the JNDI pool you need to remove the Postgres JDBC driver (it should be named postgresql-X.X-XXX.jdbc3.jar) from the GeoServer WEB-INF/lib folder and put it into the TOMCAT_HOME/lib folder. Then the following code must be written in the Tomcat configuration file TOMCAT_HOME/conf/context.xml
