Hi,<br />
<br />
I was reading as below<br />
<br />

<blockquote>
Metadata is a new addition to the Java language with the introduction of J2SE 5.0. It effectively allows developers to elaborate on class definitions, adding further descriptive and behavioral information to the generation of the class file. The EJB 3.0 specification has used this facility to describe the majority of its workings. To learn more about this new addition to the Java language, read the official specification
</blockquote>
<br />
How metadata used to handle before j2SE5.0. What kind of class definitions and descriptive and behavioral information does meta data consist of. Where to find that information. I feel descpriptive way of saying @session etc makes lot of things unclear to developer.<br />
&nbsp;Please advise.

Java is a platform-independent, object-oriented programming language and run-time environment, designed to have as few implementation dependencies as possible such that developers can write one set of code across all platforms using libraries. Most devices will not run Java natively, and require a run-time component to be installed in order to execute a Java program.

Java Enterprise Edition (Java EE) is a specification defining a collection of Java-based server and client technologies and how they interoperate. Java EE specifies server and client architectures and uses profiles to define technology sets targeted at specific classes of applications. All Java EE profiles share a set of common features, such as naming and resource injection, packaging rules and security requirements.

Java EE

Programming includes both the specifics of the language you’re using, like Visual Basic, .NET, Java and others, but also the best practices in user experience and interfaces and the management of projects, version control and development. Other programming topics are related to web and cloud development and system and hardware programming.

JavaServer Pages (JSP) allow the development of dynamically generated web pages. It uses the Java programming language; JSP pages are translated into servlets at runtime, with each servlet being cached and reused until the JSP is modified. JSP allows Java code to be interleaved with static web markup content, so the resulting page can be compiled and executed on the server to deliver the content.
