Java Glossary Term - E
Java EE 5 Java Platform, Enterprise Edition 5 (Java EE 5) mainly focuses on
to make the development more easier, having richness of the J2EE 1.4 platform.
It provides new features along with updated features such as JavaServer
Faces (JSF) Technology, Enterprise JavaBeans (EJB) Technology 3.0, and the latest web services APIs, Java EE 5
in order to make coding more simple and more straightforward, as well as
maintaining the power established in the previous versions.
Java EE Java Platform, Enterprise Edition
or Java EE is builds on the solid foundation of Java Platform, Standard
Edition (Java SE) and widely used platform for server programming in the Java
programming language. The Java EE Platform differs from the Standard Edition
(SE) of Java in that it adds additional libraries which provide functionality to
deploy fault-tolerant, distributed, multi-tier Java software, based larg
modular components running on an application server.
Exceptions in java Exceptions are used for handing errors and other
exceptional events in Java programming language.
Enum Data Types Enum type is a type which consist of fixed set of constant fields.
like direction and days includes values NORTH, SOUTH,
EAST, and WEST and SUNDAY, MONDAY, TUESDAY, WEDNESDAY, THURSDAY, FRIDAY and
SATURDAY respectively. Since they are constants so we are taking these values
into the uppercase letters.
Eclipse Eclipse is an extensible open source development
platform mainly written in java. It is simply a framework consisting of the Java
Development Tools (JDT) for building a development environment from plug-in
A Java Virtual Machine (JVM) is a collection of programs and data structures
that uses a virtual
machine to execute computer programs and scripts. The JVM is distributed along with a set of standard
class libraries which implement the Java API
(Application Programming Interface).
Java Error Errors in java are the abnormal conditions that occurs
in a program. Error in java is a subclass of the Throwable class that describes
the serious problems that a reasonable application should not try to catch.
JSP Error Pages Lack of few things may make an application less
polished and professional than a server's default exception page. Even though
most of the well-designed pages generally shows the stack trace as well as
the exception name and makes your application look broken.
Template Data: It is the static part of a jsp
page. Anything that is copied as it is directly to the response by the JSP
server is known as template data.
EJBContext javax.ejb.EJBContext is an interface, which is
implemented by the EJB container. It provides a context of an enterprise Bean
instance to the runtime container-environment.
In OOPs, these concepts are implemented through a class definition and achieved
through the object creation process, programmatically.
The else Keyword The
else is the one more keyword of Java.
It isused to specify a statement or block of statements that are executed
when the condition for testing specified by the if keyword evaluate to
false. When the if condition evaluates to false, the code after the else
keyword is executed.
The extends Keyword The
is a Java keyword, which is
used in inheritance process of Java. It specifies the superclass in a
class declaration using extends keyword.
The finally Keyword The
finally is a Java keyword that is used to define a block that is alwaysexecuted in a try−catch−finally statement. In
java, there are three clauses named try, catch and
finally used as exception handler components.
