What is an Application Server?


An application server is a program on a
computer that runs other applications.
Since the Java platform became very popular,
the term “Application Server” may refer to J2EE
application servers in some texts.
Types of Application Servers

We can divide application servers into
three types:
 J2EE
based
 Non-J2EE based (PHP, Perl etc.)
 Microsoft based (COM, ASP.NET etc.)
History Of Application Servers

In latter 1990’s Centralized computer concept became more
important due to demand in sharing data and functionalities with
other applications,

This would have been a return to the much older model of
computing as it was done in the 1960s, with a large, very expensive
central computer being accessed by multiple users using dumb
terminals. The difference now was the widespread use of the GUI.

These servers first appeared in client/server computing and on
LANs. At first, they were often associated with "tiered" applications

Since the breakout success was made by Java, application server
always refers to J2EE
History Of Application Servers


JOnAS application server, developed by the ObjectWeb
consortium, is the first non-commercial, open source
application server to have reached the official
certification of compliance with J2EE,
The term application server has also been applied to
various non-J2EE and non-Java offerings. (with the
rising popularity of .NET-Microsoft Application Server).
Additional open source and commercial application
servers are available from other vendors (the Base4
Server and Zope ),
JBoss
JBoss is an open source application
server which was first released in 1999.
 Source code can be found at
http://sourceforge.net/projects/jboss
 The latest release of JBoss Application
Server is JBoss AS 4.0

JBoss Properties
JBoss 4.0 is compliant to the J2EE 1.4
specification. So J2EE components such
as JBs and EJBs can be reused even if
they were developed on other application
servers
 It also supports J2EE Web Services and
Service Oriented Architecture

JBoss Properties
Since JBoss is java based, it can be used
on any operating system that supports
java
 JBoss requires smaller memory than other
application servers, so it is faster
 It has a very powerful documentation on
its web page

WebLogic




a J2EE application server and also an HTTP web server
by BEA Systems for Unix, Linux, Microsoft Windows, and
other platforms,
supports Oracle, DB2, Microsoft SQL Server, and other
JDBC-compliant databases
WebLogic Server supports WS-Security and is compliant
with J2EE 1.4
The most reliable server is no doubt BEA’s WebLogic
Application Server. It is the only one which can resist to
over 3000 concurrent clients without throwing exceptions
WebLogic Architecture:
BEA WebLogic Server is part of the BEA WebLogic
Platform™. The other parts of WebLogic Platform are
a) Portal, which includes Commerce Server and
Personalization Server (which is built on a BEAproduced Rete rules engine), b) WebLogic Integration,
c) WebLogic Workshop, an IDE for Java, and d) JRockit,
a JVM for Intel CPUs.
Extra Properties Of WebLogic:
1) Rich client options - supports Web browsers and other
clients that use HTTP; Java clients that use RMI or IIOP;
and mobile devices that use WAP.
2) Enterprise e-business scalability - Critical resources are
used efficiently and high availability is ensured through
the use of Enterprise JavaBean business components
and mechanisms
3) Robust administration - offers a Web-based
Administration Console for configuring and monitoring
WebLogic Server services.
4) E-commerce-ready security - provides SSL support for
encrypting data transmitted across WebLogic Server,
clients, and other servers.
WebLogic Properties

Use JBoss When..

For better performance and for applications that
are not extremely complex, JBoss is the optimal
choice. It is also free but is needed more
knowledge about J2EE and have to manually
create deployment packages. Runs on any Java
platform; is robust and can handle missioncritical applications. Lacks some control and
management features for PITH (Projects in the
Huge); simple projects require only some
programming knowledge; anything else and
you'd better have depth.
Use WebLogic When...


The WebLogic Server is the most reliable server
and complex application server and offers the
best support for the real-world applications.
Although it needs a higher level of
understanding of the J2EE concepts, has a
complex configuration and is very expensive,
this server is the best choice for a secure and
fault-tolerant application.
Conclusion:


Since JBoss is open source, and is a very
complete and well-build package, people tend to
use JBoss more commonly and experienced
less frustration with JBoss. With a basic open
source framework to build on and make desired
small changes to, people can get what they want
in a hurry.
On the other hand, WebLogic is the most
reliable application server and is more suitable
for complex, fault-tolerant applications.
