Java or .NET? XML Rich-Client AJAX Technology Brings Zero-Install Rich Client To Java

Which platform to use Java or .NET? Developers ask this question all the time

Which platform to use Java or .NET? Developers ask this question all the time. Java has been widely adopted because of its overwhelming benefits on the server side, but Java has less to offer on the client side. .NET has made inroads into the enterprise by leveraging its stronger rich-client capabilities. An alternative solution for enterprise-scale Internet application development is the emerging XML-based rich-client technology.

.NET Erosion from the Client Side
There are good reasons why Java is the platform of choice for server-side computing. J2EE is an open standards-based platform that enables open integration. Java enjoys broad industry support, including vendors like IBM, Sun, and Oracle, as well as upstarts like Nexaweb and Sonic Software. J2EE is cross-platform, giving customers the freedom to deploy in different environments. It has proven enterprise strength. By comparison, .NET has obvious limitations. It is limited to Windows deployment only; it's a single-vendor solution, and lacks industry support from other vendors to meet enterprise requirements.

On the other hand, .NET has stronger client-side capabilities than Java. Java AWT is based on an architecture that offers limited out-of-box capabilities. Java Swing offers better out-of-box functionality, but it's complex and difficult to use. It is possible to develop Java applications with a rich look-and-feel using AWT or Swing, but complexity and developer skills requirements are high. By contrast, the barriers to developing strong .NET client applications are lower. Your typical corporate developer can easily write sophisticated VB.NET desktop applications with a professional look-and-feel.

Another option is to develop thin-client applications using HTML. HTML applications are "zero-install" thin-client applications, while both Java and .NET client apps have a heavy client-side footprint and require a significant download. Besides solving network bandwidth issues, "zero-install" translates directly into lower maintenance and support costs. The skill set requirements and complexity of HTML is much lower than either .NET and Java. Unfortunately, HTML isn't suitable for handling the level of complexity, scale, and time-sensitivity required by enterprise programs. For applications with non-linear workflow, complex integration, large data sets, or time criticality, Java or .NET rich clients have been the only viable options.

Most business applications are user-oriented. Client-side issues such as look-and-feel, richness, and performance directly impact business user productivity. As a result, client-side choice can influence server-side architecture decisions. Because Java doesn't have a compelling solution on the client side, many applications are written with .NET. Eventually this could lead to a greater adoption of .NET for easier integration and management, eventually eroding J2EE's market share.

XML Rich Client
Now there's an alternative. XML rich client-technology serves rich-client applications on-demand by using XML from J2EE or Service Oriented Architecture (SOA) environments. Using XML rich-client technology, J2EE can deliver enterprise Java applications with higher performance than .NET - not only visually and functionally richer, but easier to deploy and maintain, with a thinner footprint, faster performance, greater scalability, and lower complexity.

Sample XML-Based Rich Client Technology Code
With XML rich-client technology, Web developers can build and deploy Web applications with the same richness and performance as the best Java Swing or .NET client apps without losing the "zero-install" and "universal delivery" advantages of HTML. The difference is that an XML-based rich-client application would send out XML to the client side, which is processed by the software's client, instead of HTML being processed by a browser, as in a normal Web application.

Figure 1 shows a sample form. The code behind it is as follows:

<?xml version="1.0" encoding="UTF-8"?>
<dialog height="212" title="Sample Form" width="275">
   <layoutmanager layout="nulllayout"/>
   <tabbox borderstyle="null" height="168" width="248" x="8" y="8">
    <tab text="tabPage1">
     <layoutmanager layout="nulllayout"/>
     <label height="23" text="Please Enter Your Card Number Below:"
     width="224" x="6" y="24"/>
     <textbox height="20" text="" width="216" x="8" y="48"/>
     <button height="25" text="OK" width="60" x="170" y="100"/>
    <tab text="tabPage2"/>

Figure 2 shows a sample chart. In normal Web apps, such charts are generated as static GIF images that are sent to the browser for display. With XML-based rich-client technology, XML can be sent directly to the client:

<?xml version="1.0" encoding="UTF-8"?>
<dialog title="Auto-resizable Chart Example" bordercolor="blue" width="534"
   <layoutmanager layout="borderlayout"/>
   <chart layoutpos="center">
    <series points="200,100,400,300,200,200,100,400,300,200" stroke="red"
    <series points="300,200,100,200,400,300,200,100,200,400"     stroke="blue"
    <labelaxis fgcolor="red"/>

The Benefits of XML Rich Client Technology

  • The Future is XML - The rapid adoption of XML for server-side computing makes XML a natural candidate for client-side computing. Even Microsoft has made a commitment to this trend. The next-generation Windows, Longhorn, will support the use of XML for Windows desktop applications.
  • XML Rich-Client Technology Significantly Lowers Application Complexity and Skill Set Requirements - One benefit of XML rich-client technology is that it enables enterprise-class Internet applications while lowering development/maintenance complexity. XML rich-client technology uses the power of XML, which is more efficient and extensible than procedural programming languages like Java, C#, C++, or JavaScript. Code created in XML is simpler, takes up fewer lines, and is easier to read and process. Someone with HTML skills can easily understand the code, while C# code and Java Swing code require intimate knowledge of Object-Oriented programming.

Cloud-Native thinking and Serverless Computing are now the norm in financial services, manufacturing, telco, healthcare, transportation, energy, media, entertainment, retail and other consumer industries, as well as the public sector. The widespread success of cloud computing is driving the DevOps revolution in enterprise IT. Now as never before, development teams must communicate and collaborate in a dynamic, 24/7/365 environment. There is no time to wait for long development cycles that produce software that is obsolete at launch. DevOps may be disruptive, but it is essential. DevOpsSUMMIT at CloudEXPO expands the DevOps community, enable a wide sharing of knowledge, and educate delegates and technology providers alike.
In a recent survey, Sumo Logic surveyed 1,500 customers who employ cloud services such as Amazon Web Services (AWS), Microsoft Azure, and Google Cloud Platform (GCP). According to the survey, a quarter of the respondents have already deployed Docker containers and nearly as many (23 percent) are employing the AWS Lambda serverless computing framework. It's clear: serverless is here to stay. The adoption does come with some needed changes, within both application development and operations. That means serverless is also changing the way we leverage public clouds. Truth-be-told, many enterprise IT shops were so happy to get out of the management of physical servers within a data center that many limitations of the existing public IaaS clouds were forgiven. However, now that we've lived a few years with public IaaS clouds, developers and CloudOps pros are giving a huge thumbs down to the...
Kubernetes is an open source system for automating deployment, scaling, and management of containerized applications. Kubernetes was originally built by Google, leveraging years of experience with managing container workloads, and is now a Cloud Native Compute Foundation (CNCF) project. Kubernetes has been widely adopted by the community, supported on all major public and private cloud providers, and is gaining rapid adoption in enterprises. However, Kubernetes may seem intimidating and complex to learn. This is because Kubernetes is more of a toolset than a ready solution. Hence it’s essential to know when and how to apply the appropriate Kubernetes constructs.
To enable their developers, ensure SLAs and increase IT efficiency, Enterprise IT is moving towards a unified, centralized approach for managing their hybrid infrastructure. As if the journey to the cloud - private and public - was not difficult enough, the need to support modern technologies such as Containers and Serverless applications further complicates matters.
