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.

4
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.)

5
History Of Application Servers

• In latter 1990s 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

6
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 ),

7
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

8
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

9
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

10
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 BEAs
  WebLogic Application Server. It is the only one
  which can resist to over 3000 concurrent clients
  without throwing exceptions

11
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
  BEA-produced Rete rules engine), b) WebLogic
  Integration, c) WebLogic Workshop, an IDE for
  Java, and d) JRockit, a JVM for Intel CPUs.

12
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.

13
WebLogic Properties

• WebLogic Server includes .NET interoperability
  and supports the following native integration
  capabilities
• Native enterprise-grade JMS messaging
• J2EE Connector Architecture
• WebLogic/Tuxedo Connector
• COM Connectivity
• CORBA connectivity
• IBM WebSphere MQ connectivity
• Latest version 9.1 - Diablo

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 mission-critical
  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.

16
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.

17
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.
