Thread: Clearing up the air on javaEE

Because networking (like AWT/Swing, NIO, RMI, JDBC, etc...) is not part of SCJP/OCJP. The APIs I have mentioned are "advanced" APIs. While these exams mainly cover the "core" language (up to threading). If you have a very good knowledge of the core language you can virtually understand and use all (many, if not all) other APIs.

In the real "industry" world it's surely necessary to have a very good knowledge of the core Java language plus ...
- generics & collections
- threading, concurrency
- basic I/O, at least the entire java.io package (SCJP/OCJP only cover a small part of it)
- regular expressions (sometimes are very useful)

Then depending on the work context, you can need to know JDBC, AWT/Swing and/or other more advanced technologies/frameworks (JPA, Servlets/JSPs, etc...). And it's possible that you need to acquire a higher certification like the SCWCD.

About networking, it depends on what precisely. In real industry world it's very rare that you need to use directly, for example, Socket/ServerSocket/DatagramSocket, unless you are asked to develop an implementation of an existing or a new applicative protocol. Which is certainly not a common task.

other do I have to acquire to arm my self with before I take upon javaEE.

About the JavaEE, the basic part at "presentation" level is composed by Servlet/JSP. And this is the main topic of SCWCD (now "Oracle Certified Professional, Java EE 5 (or 6) Web Component Developer").

Many people can tell you that there are better technologies, like JSF, Spring, Struts, etc... It's true, these are more modern and widely used. But a minimal knowledge about Servlet/JSP is however a good "base".

If you mean Java at "server side", no, the core Java language and Java SE framework are not sufficient. You need to know at least Servlet/JSP.
