Definition - What does J2EE Client mean?
A J2EE client is an application component that accesses the J2EE environment to process requests or use J2EE services. Requests vary from HTTP to more complex J2EE server communication across different networks.
The primary difference between J2EE and stand-alone clients is that a J2EE client is able to access different J2EE services. A J2EE client is either a Web client or an application client.
Techopedia explains J2EE Client
A Web client is comprised of two parts: dynamic Web pages produced by components and a Web browser that delivers pages received from the server. A Web client is also known as a thin client, which does not handle critical operations, such as database questioning or managing complicated business rules. These operations are handled by enterprise beans executed on the J2EE server.
Some Web pages are comprised of applets, which can be a disadvantage because a system must have a Java plug-in and security files to execute applets in a Web browser.
An application client is a client-side component with a graphical user interface. It can access a business tier’s enterprise beans and establish HTTP connections with servlets running in the Web tier.
