![]() ![]() This is also the place where we can add the dependencies. Here you will also find your project main POM file, which will look like this:ħ. As this is a new project, you will notice that the Dependencies tree is empty:Ħ. After clicking Finish, you will notice a tree on the left-hand side of your screen where Modules, Project Files, and Dependencies are listed.ĥ. ![]() Next, it will ask you to enter project name and other details:Ĥ. A pop up will open asking you to enter Categories and Project type, As we are using Maven I have chosen Maven as Category and POM as project type, as shown below:ģ. Open Netbeans and Click on File → New Project.Ģ. We will be using Netbeans for a sample test project.ġ. As a prerequisite, I will assume you have any JAVA IDE installed on your system, like Eclipse, Netbeans, etc. Here are step-by-step instructions for how to add PostgreSQL’s JDBC driver dependency. ![]() Step-by-step instructions for adding the PostgreSQL JDBC driver dependency In Maven, libraries, JAR files, are all collectively called dependencies because you add them to the pom.xml file to create your Maven project. You also need libraries when you construct projects. JAR files help you compress, decompress, and archive files. The ZIP format Java ARchive (JAR) file is essential in Maven project development. Here, is the name of the company or group that created this project, is the name of the project, as the name suggest is the version of the project, is the main tag where we will include all the dependencies of the project, and is the tag where we specify individual dependencies. Maven uses these tags to uniquely identify the project. It's the place where we can specify plugins, dependencies, and project versions.īelow is a sample POM file where we can see a few basic XML tags. It is an XML file that stores crucial information about a Maven project, including configuration details used by Maven. You can browse around the Maven repository to get a sense of the many dependencies that might be needed for your project. You can simply add the PostgreSQL JDBC dependency to the project's POM file. You do not need to add the JAR files manually yourself. The benefit of Apache Maven is that you only need to add dependencies in the POM file the rest is taken care of by Maven. One of the most common is using Apache Maven. There are different approaches to design and configure your project in Java. PostgreSQL JDBC driver and Maven repositories It streamlines the project development process, enabling you to create and publish swiftly. The Maven project is hosted by the Apache Software Foundation, where it was formerly part of the Jakarta Project. Maven can also be used to build and manage projects written in C#, Ruby, Scala, and other languages. Maven is a build automation tool used primarily for Java projects. So, to connect to a PostgreSQL database, you will need to go to the PostgreSQL website, download the PostgreSQL JDBC driver JAR file, and add it to your project. PostgreSQL, the world's best open source relational database, comes with its own JDBC driver, which can be found on the PostgreSQL community website. To connect your database in Java, you need to have a JDBC driver. JDBC drivers are the easiest way for many developers to connect to databases from their Java applications.ĭrivers do a fair amount of work, from the basics of opening socket connections from your Java application to the database and submitting your SQL queries, to more advanced features, like offering the ability to receive events from the database. Once primarily available for relational databases, they are now available for almost any type of data source, such as Big Data, NoSQL, and SaaS. These drivers vary for different frontend programming languages. To connect a frontend application to any database you need to use a respective database driver. Now you can use this guide as an overview.īefore jumping in to the nitty gritty, let's first get a basic overview on why we need a PostgreSQL driver. Have you at any point needed to connect to your PostgreSQL database using Java and didn't have a clue how to add it as a Maven dependency?
