Similarly, Eclipse EE is a version of Eclipse that comes with a bunch of tools that make it easier to write server code. Jakarta EE isn’t an alternative to regular old Java- it’s built on top of it. When you use JSP, you’re using Jakarta EE. When you add your server’s lib directory to your classpath, or when you add the rvlet dependency to your pom.xml file, you’re using Jakarta EE. jar files that come with your Jetty or Tomcat server. But we’ve kept using the term EE to describe stuff used for developing interactive websites.Īnyway, you’ve already been using Jakarta EE. Now interactive websites are all over the place, not just owned by businesses. That’s where the term enterprise (aka business) comes from. I think the term “enterprise” is a little outdated, because it comes from a time when the only interactive websites that existed were owned by businesses, like online stores. That EE stands for Enterprise Edition, which are versions of Java and Eclipse that include tools for server development. You might have seen stuff referred to as EE, as in Java EE, Jakarta EE, or Eclipse EE. Instead, this tutorial talks about using Eclipse to develop web apps. This tutorial assumes you’re already familiar with Eclipse from the Eclipse tutorial, so I won’t spend a ton of time introducing ideas like workspaces and projects.
It’s important to understand the fundamentals of how a web app works: stuff like running the server, and writing and compiling servlet classes.īut as your code gets more complicated, using a code editor like Eclipse will make your life much easier. So far you’ve been writing all of your code in a text editor, and compiling your servlet classes via the command prompt. Import .JSP Next: Post Requests Eclipse EE tutorial java server eclipse Next we will create UserService.java, User.java,UserDao.java files under the com.tutorialspoint package. To do this, right click on src in package explorer section and follow the option − New → Package. First we need to create a package called com.tutorialspoint. Now let us create the actual source files under the UserManagement project. Now use Add JARs button available under Libraries tab to add the JARs present in WEBINF/lib directory.
Now, right click on your project name UserManagement and then follow the option available in context menu − Build Path → Configure Build Path to display the Java Build Path window.
Copy all jars from following directories of download jersey zip folder in WEB-INF/lib directory of the project. Once your project is created successfully, you will have the following content in your Project Explorer − Adding the Required LibrariesĪs a second step let us add Jersey Framework and its dependencies (libraries) in our project. Now name your project as UserManagement using the wizard window as shown in the following screenshot −
Follow the option File → New → Project and finally select the Dynamic Web Project wizard from the wizard list. The first step is to create a Dynamic Web Project using Eclipse IDE. So, let us proceed to write a simple Jersey Application which will expose a web service method to display the list of users. Here, I am also assuming that you have a little working knowledge of Eclipse IDE. Before you start writing your first example using the Jersey Framework, you have to make sure that you have setup your Jersey environment properly as explained in the RESTful Web Services - Environment Setup chapter. Let us start writing the actual RESTful web services with Jersey Framework.
