IntelliJ is a trading IDE with a trustworthy following that guarantee of it. It has excellent GUI and J2EE support. It is expandable through its plugins. It has exceptional quality is its outstanding refactoring support. Streamline enterprise development with MyEclipse, the all-in-one Eclipse Java IDE, with support for a wide range of frameworks. Content assist, as-you-type validation, syntax highlighting, graphical and form based editors, and built-in libraries are just a sampling of features that improve your development experience.
By default, a Java Enterprise project in IntelliJ IDEA is not configured for full enterprise application development.
Enable enterprise application support for your project
In the Project tool window, right-click the root module directory and select Add Framework Support.
In the Add Framework Support dialog, select JavaEE Application and click OK.
This adds a deployment descriptor application.xml under META-INF in your project directory, a JavaEE Application facet and an enterprise application archive (EAR) artifact configuration.
Manage deployment descriptors
J2ee Ide Best
A deployment descriptor describes how to deploy your application. It contains information about the configuration requirements, container options, and security settings. By default, IntelliJ IDEA generates one deployment descriptor for your enterprise application: META-INF/application.xml.
Press Ctrl+Alt+Shift+S to open the Project Structure dialog.
Open the Facets page and select the javaEEApplication facet.
You can click to add other deployment descriptors. You can also add deployment descriptors that are specific to your application server (runtime deployment descriptors).
Manage application artifacts
Artifacts are the main application deliverables that you deploy to an application server.
Press Ctrl+Alt+Shift+S to open the Project Structure dialog.
Open the Artifacts page and select the default exploded EAR artifact configured for your application. You can see and configure the settings of this artifact or click to add a regular EAR archive artifact and create a manifest file for it.
You can build any of the configured artifacts by selecting Build | Build Artifacts from the main menu. You can also add these artifact configurations to your application server run configuration so that IntelliJ IDEA builds and deploys the artifacts as necessary.
At IDR Solutions we make use of a Open Source Java Application Server called Glassfish to run our free PDF to HTML5 Converter. I have wondered what the alternatives were to Glassfish and decided to do some research into other Open Source Java and JavaEE Application Servers.
Join me as I guide you through my Top 10 Open Source Java and JavaEE Application Servers.
What is an Application Server?
Eve online client. Firstly what is an Application Server? An application server can often be described as a software framework that resides in the middle tier of a server centric architecture.
The application server can often be viewed as part of a three-tier application, which are a graphical user interface (GUI) server, an application (business logic) server, and a database and transaction server and provide services for security and state maintenance, along with data access and persistence.
J2ee Identify
For Web applications, an application server will be running in the same environment as its web server(s), and application servers are there to support the construction of dynamic pages and implement services like clustering, fail-over, and load-balancing, so developers can focus on implementing the business logic.
At IDRsolutions we like to describe it to non-technical users as a magic door. It allows you to write code to run on a server and code on a client and allow them to talk to each other. It all just works and handles all the complexity transparently for you.
So now we have established what an Application server is, we will now take a look at the available Java Application Servers.
Glassfish
GlassFish is an open-source application server project originally started by Sun Microsystems for the Java EE platform and now part of the Oracle Corporation. It is available under a dual-license: the Common Development and Distribution License (CDDL) and the GNU General Public License (GPL) with the classpath exception. Oracle no longer provides commercial support for GlassFish Server but several organisations have filled that space, most notably Payara.
GlassFish is often considered as the reference implementation of Java EE and so supports Enterprise JavaBeans (a managed, server-side component architecture for modular construction of enterprise applications), JPA (Java Persistence API ), JavaServer Faces, JMS (Java Message Service), RMI (Java Remote Method Invocation), JavaServer Pages, servlets and more. Glassfish allows you to to create enterprise applications that are portable and scalable, and that integrate with legacy technologies. Optional components can also be installed for additional services.
It is built upon a modular kernel powered by OSGi, and runs straight on top of the Apache Felix implementation. It is also capable of running with Equinox OSGi or Knopflerfish OSGi runtimes. HK2 abstracts the OSGi module system to provide components, which can also be viewed as services and injected into the run time and uses a derivative of Apache Tomcat as the servlet container for serving Web content, with an added component called Grizzly which uses Java New I/O (NIO) for scalability and speed. We have previous covered how to set up Glassfish on a Linux Server.
If you are looking for an example of deploying a web app, there are some examples on our support section, where we show you how to deploy our software to GlassFish here and to Payara here.
JBoss Enterprise Application Platform
The JBoss Enterprise Application Platform which is also known as JBoss EAP is a open-source (available under the GNU Lesser General Public License) Java EE-based application server runtime platform used for building, deploying, and hosting highly transactional Java applications and services.
