Comparison between Java EE and .NET

Describe about the Enterprise Computing In Terms of Java EE and .NET .

Enterprise computing can be referred to as the mission-critical systems. The business of an organization relies on these systems. In addition to that, a database is incorporated in the system. It is required to understand the meaning of the enterprise as most of the technical products in the market are getting marketed as enterprise, buzzword (Pal et al. 2014). The shared solution to the business is provided through the enterprise computing.

In this report the compression of Java EE and .NET will be carried out as layered and component-based model. Theo whole report is based on the analysis of Java EE and .NET.

Comparison as Layered model:

Java EE: The scalability increases. This is because of its capacity of numerous level organization and the level decoupling it brought. For instance, the information level can be scaled up by database grouping without different levels including. The web customer side can be scaled up by burden balancer effectively without influencing different levels (Liu and Shen 2015). Windows server can be bunched effortlessly for burden adjusting and failover. What's more, business level server can likewise be grouped to scale up the application, for example, Weblogic bunch in J2EE (Basanta and García 2014).           

Better adaptation to internal failure capacity, taken as an example, the databases in information layer can be bunched for failover or burden equalization reason without influencing different layers (Liu and Shen 2015).

.Net: In a Layered design programmers isolate the UI as of the business foundation as the developerll as the business foundation from the information admittance basis. Separation of worries amongst these reasonable sections and layers is fluently accomplished through the support of covered production (Esposito 2015).

For instance on the off chance which the developer require a windows UI because different to the developer program interface, this be supposed to be probable within a straightforward and rapid way by merely displacing the user interface aspect (He, Yan and Da 2014). The different sections resembling business foundation, information way in and the database carry on as previous way.

Java EE: in two-tier architecture the components are client and server. Server provides the database and logics to client for accessing the application.

In three-tier architecture there is an additional component called middle tier. This tier holds the business rules (Liu and Shen 2015).

In N-tier architecture the client is connected to application server which provides access to the data base. In terms of web application, the web server is installed betthe developeren application server and database (Ji et al. 2014).

Advantages of Layered Design

.NET: Within presentation layer the tow kind of entities are user interface and user interface process.

Within business layer the components are business workflows, business entities and service interfaces (Yingxia and Zimian 2014).

In terms of data layer the components are data access entities, foundation services and service gateways.

Parts of the Platforms:

Java EE: The EJB or Enterprise Java Beans was developed using the outset. It is because for supporting the entities from various vendors. EJB parts can be written without knowing the environment in which they will be utilized (Jendrock et al. 2014). Applications in view of EJB parts are freely coupled:  Loosely coupled frameworks are less demanding to test and keep up and components of an approximately coupled framework are simpler to reuse.

Components of Java EE

Figure 1: Components of Java EE

(Source: Willnecker et al. 2015, pp-103)

The characteristics of the Java EE components are first, encapsulation through container, location simplicity, distributable component interactions are supported and naming system is used for obtaining the component references (Jendrock et al. 2014).

.NET: The System.ComponentModel namespaces contain sorts that execute the run-time and plan time conduct of segments and controls." The usefulness the organizationgive could be anything. What the ComponentModel gives is metadata and the result is that the organizationcan outline segments that can be utilized as a part of the visual planner (Souza 2012). Subsequently:

public interface IDesigner : IDisposable {

        IComponent Component {get;}       

        DesignerVerbCollection Verbs {get;}

        void DoDefaultAction();

        void Initialize(IComponent component);


The namespace likewise gives the TypeDescriptor/Convertor stuff, again usable for configuration time access to properties (Sorokin 2015).

Java EE: Java EE epitomizes parts in compartments that provide life-cycle administration, isolate segments from different parts and isolate segments from the runtime environment (Hoorn et al. 2012).

Java EE Component Interaction

Figure 2: Java EE Component Interaction

(Source: Gupta et al. 2012, pp-12)

In terms of the distributed and local entity interactions, the engineer indicates whether a collaboration is to be neighborhood or distributable. In terms of local, the application server makes segments accessible to each other in the same JVM™ machine (Hoorn et al. 2012). On the other hand regarding distributable, the application server gives a RMI base by which segments convey. Both systems have related expenses and advantages.

The RMI framework must have the capacity to deal with the taking after configuration issues marshaling and unmarshalling of contentions and return values, passing circulated special cases and passing security setting and exchange connection.

Component of Individual layers and Their Functions

Calling Conventions among Local and Distributable Components

(Source: Gupta et al. 2012, pp-13)





System.ComponentModel namespace gives classes that are utilized to actualize the run-time and plan time conduct of parts and controls (Takala 2013). This namespace incorporates the base classes and interfaces for actualizing traits and sort converters, official to information sources, and permitting parts.


Gives classes that constitute the center of the Managed Extensibility Framework, or MEF.


System.ComponentModel.Composition.Hosting gives Managed Extensibility Framework (MEF) sorts that are helpful to engineers of extensible applications, or hosts (Highina et al. 2014).


System.ComponentModel.Composition.Primitives gives the primitive sorts hidden the MEF programming model.

Runtime Foundation:

Java EE: The Java compiler, part of the Java Development Kit (JDK) deciphers the code composed by the designer into stage autonomous Java "bytecode". The Java Virtual Machine (JVM) makes an interpretation of Java bytecode into directions conceivable to the fundamental working framework. On the off chance that the Java class libraries and a JVM are available on a PC, the machine is said to convey a Java Runtime Environment (JRE) (Stark, Schmid and Borger 2012). Cutting edge JRE's incorporate more than simply the JVM, such a Just-In-Time compilers and byte code verifiers.

.NET: The Common Language Runtime or CLR is a superior motor for running applications manufactured utilizing the .NET Framework. Code that objectives the runtime and whose execution is overseen by the runtime is alluded to as oversaw code. Duty regarding errands, for example, making objects, making technique calls, thus on is designated to the CLR which empothe developerrs it to give extra administrations to the code as it executes (Erickson 2013).

While the part is running, the CLR gives administrations, for example, memory administration (counting rubbish accumulation), process administration, string administration, and security implementation—and fulfills any conditions that the segment may have on different segments.

Java EE:



Components of Services

Java Virtual Machine or JVM

High Quality GC

1.   Parallel, Collection and Concurrent

2.   Low whole allocation price

High Quality Machine Code Generation

1.   Two JITs, Profiling and JIT'd Code Management

2.   Bytecode cost model

Uniform Threading & Memory Model

Locks (synchronization), wait, notify and volatile (Stark, Schmid and Borger 2012)

Type Safety

Dynamic Code Loading

Class loading, re-JIT'ing and Deoptimization

Quick high-quality Time Access


Internal introspection services

Reflection, JVMDI/JVMPI, JNI, Agents and JVMTI





CLR or Common Language Runtime

Type Safety

Is alluded as the specifically highlight. It permits to get to memory just in approved ways ensures that it is inside the limits. It guarantees that code can't perform operations that are invalid for an article.

Managed Code execution

It is the procedure took after by the CLR from stacking MSIL, changing over it into machine code, memory administration. Overseen code execution additionally handles JIT assemblage, handles special cases, and affirms sort the developerllbeing and security issues (Erickson 2013).

Side-by-side execution

Gives a chance to execute numerous renditions of an application or segment on one PC. It permits the execution of different forms of CLR and numerous renditions of utilization executing in the meantime on the same PC.

High quality GC: The cycles within the object graphs can be managed with more efficiency. The operations of the garbage collector become quicker.

High Quality Machine Code Generation: The profiling of the information which is only available at time of runtime can be made more sufficient (Stark, Schmid and Borger 2012).

Type Safety: The validation of the types of the variable will be more effective and accurate.

Managed Code execution: It provide benefits by providing services such as memory management, exception handling, thread management, garbage collection and safety.

Side-by-side execution: Through this the system can be running various versions of the application within the same system (Erickson 2013).

Java EE: Java EE software is expressed within a JAR or Java Archive testimony, a WAR or Web Archive document, or an EAR or Enterprise Archive document. An EAR or WAR record is a standard JAR, .container, document through a .ear or .war development. Utilizing EAR, WAR, and JAR modules and records creates it believable to accumulate various distinctive Java EE applications utilizing a portion of the similar sections (Jendrock et al. 2014). No extra coding is necessary; it just requires a process of collecting or bundling diverse Java EE components into Java EE, WAR, EAR or JAR records.

Comparisons like Component-Based Form

Framework of EAR File

(Source: Highina et al. 2014, pp-15)

The two sorts of distribution identification are runtime and Java EE. Java EE organization identification is distinguished by Java EE specific and is utilized for arranging distribution settings on some Java EE-agreeable practice. A runtime distribution descriptor is used for designing Java EE execution particular limitations.

.NET: To start with, the organizationwill investigate the most straightforward .NET Framework application, the customary Hello World system, written in Visual C# and talked about in point of interest in the instructional exercise, Introduction to Developing with the .NET Framework.

Figure 5: Hello world Subdirectory C# Source Code

(Source: He, Yan and Xu 2014, pp-1589)

This stand-alone, executable project composes a solitary line to System.Console, which is a sort contained in the .NET Framework class library. The system does not reference whatever other libraries and does not itself create a library. Giving advantageous access to sorts in the .NET Framework class library requires the utilizing articulation:

Likewise, the system characterizes a class to encase the application code: class MainApp {

At long last, the system characterizes the Main technique to give the section point to the code: public static void Main () {

Build.bat contains the accompanying single line, which is all that is important to order this little program: csc.exe /debug+ Hello.cs (Hu and Zhang 2014).

Supporting B2B through Soad and Mda Methods for Both J2EE and .NET:

This reconciliation technique gives arrangement of ideas expected to demonstrate the two viewpoints. Ideas identified through business point of view explain the placed in components in industry and are said to by model of CIM by BPM or Business Process Model (Santos et al. 2013). Ideas identified with framework point of view are components used to portray usefulness and framework preparing, and are spoken to in PSM and PIM structure, Interface Web Service Model, Composite Application Model, by Use Case Model, Service Model, Component Model, Process Execution Model and Service Process Model (Utomo 2013). SOA is a product design planned taking into account administration situated configuration standards while administration introduction is an idea in programming building that speaks to various ways to deal with partitioned interest.

The main feature of the proposed method is that it utilizes SOA regarding the execution of structure and in terms of the development of joining phase (Santos et al. 2013). It characterizes a service oriented proposition regarding the improvement of information system’s in sharing rules to build IS’s construct only in light of administrations, utilizing them as top notch objects for the entire procedure of the IS improvement. This methodology encourages the improvement of administration arranged applications and in addition their usage utilizing current innovations, for example, Web administrations, BPEL and ESB (Utomo 2013).

Parts of the Platforms

Java EE: The connection to the system is provided through HTTP request management, session handling, supporting transaction connectivity to other systems, authentication, access control and validation of HTTP request parameter (Curry 2012).

.NET: This plat form provides support to the connection to the legacy system through message bus, component maintenance activity, query inventory database and service-to-service integration (Herzig et al. 2012).

In Terms of Technology:

Numerous substantial organizations have existing applications written in assortment of dialects, for example, COBOL, C++, SAP, and Siebel. This sort of legacy combination is a standout amongst the most difficult errands to beat when building web administration J2EE offers a few approaches to accomplish legacy incorporation:

  1. Using JMS to coordinate with existing informing frameworks (Waqar, Luders and Lundqvist 2013)
  2. Using Web administrations to incorporate with any framework
  3. Using CORBA for interfacing with code written in different dialects
  4. JNI for stacking local libraries and calling locally

.NET offers the Host Integration Server 2000 for crossing over to information and applications on centralized server legacy frameworks, BizTalk Server 2002 to manufacture XML-based business process crosswise over applications and associations (Bai et al. 2013).

J2EE has supreme preferred standpoint in this field in light of the fact that the JVM or JRE, on which J2EE is supported, is available on any phase. Another cause is that J2EE is a regular, thus it bolsters an assortment of usage, taken as an example, BEA, IBM, and Sun. To assurance the movement of J2EE, Sun has manufactured a J2EE similarity test suite (Waqar, Luders and Lundqvist 2013). Any organizations J2EE arrangement end the analysis will acquire an authorization from Sun. Conversely, .NET just keeps running on Windows, its upheld equipment, and the .NET environment. Today there a few undertakings, for example, "Mono", attempt to assemble Linux and crossplatform applications taking into account ECMA 334/335, which is the details for C# and a subset of the .NET system (CLI-normal dialect framework) put together by Microsoft. The reason for these tasks is attempting to enhance the versatility of .NET (Bai et al. 2013).

On .NET stage, Visual Studio.NET is the most effective improvement apparatuses for .NET creating. It gives an incorporated creating environment, a simple use GUI interface what's more, heaps of creating parts. Java is the main dialect support on J2EE stage (Waqar, Luders and Lundqvist 2013). Different dialects can be crossed over into J2EE stage through CORBA, web administrations, JNI, or JCA. Be that as it may, these dialects can't be blended with Java Code.


From the above study it can be concluded that both the Java EE and .NET are crucial to the implementation, development and integration of various enterprise systems. Both phases provide advancements which authorize a talented designer for constructing superiority undertaking applications. As per several cases, a modernism is every so often chosen taking into account implementation alone. Microsoft equipments have an advantage over Java in terms of developing software which needs great graphical user interfaces and which express substance to web curriculums. The identification is that Java servers are more reliable option regarding composite applications underneath higher quantities of users. Take into account the present modernism scene of organizations and the focused capabilities of organization’s personnel. It is because supplanting existing framework and preparing engineers is excessively expensive. Java, along with its several-phase adaptability, provides the organizations influence to whichever arrange with a present seller or choose the merchant of organization’s preference. As said over, Java's quality lies in libraries created by different outsider sellers. In addition to that, a variety of libraries and controls are presenting accessible for .NET. In addition to that, the collective expenditure of constructing, keeping up and conveying the application is also present. In conclusion, the phase for choosing depends upon organization’s situations and the requirements of organization’s system.
