Web applications are highly sought after because they can be updated and maintained without downloading the app. Web applications can be single-page or multi-page, with many features.
All browsers support scripting languages, including HTML, JavaScript, and CSS, typically used to create front-end online applications. Programming languages such as Java, PHP, and Python are utilized to develop the backend web application.
We now know what web apps are. Let's take a look at the web development steps before we study steps for developing Java web application.
Web Development: Step Wise Guide
Contrary to popular belief, website design and development is only part of the overall process. Coding is not required. These technologies, including HTML, CSS, and JavaScript, give the web structure and determine how we interact. The crucial stage of website development is post-launch maintenance, which remains behind the scenes but also serves as the foundation of the web's design.
This article will show you how the website development process looks. Although there are usually five to eight stages, the overall picture remains the same. Let's take the average value.
Here are seven steps to web development.
- Information Gathering
- Planning
- Design
- Content Writing and Assembly
- Coding
- Review, Testing, and Launch
- Maintenance
Timeline for Website Development
When building a website, you are likely to think about two things: price and time. The size and scope of your project will determine these two values. You can outline the entire development process by creating a website timeline. This will include tasks and milestones. This is the best way to keep track of your project's progress and ensure that you meet the deadline.
We prefer GanttPRO for this purpose. It is a simple, intuitive Gantt chart that can be used online to plan projects. Take a look at the screenshot below.
We have prepared a detailed description and estimated time for each stage of website development. There is also a checklist to make sure you don't forget anything.
Life Cycle of Website Development
Step 1.
This stage, which is the discovery and research stage, will determine the next steps. This is the most crucial stage of website development. It allows you to understand your goals, your primary goals, and your target audience. This questionnaire will help you to determine the best strategy for project management.
The news portal is different from entertainment websites. Online resources for teens look different from sites for adults. Other websites offer extra functionality, so different technologies should be used depending on the purpose. This pre-development data will help you avoid spending additional resources on unexpected issues like design changes or adding functionality not originally planned.
Estimated Time: Between 1 and 2 Weeks
Step 2.
This stage is where the developer creates data that allows customers to see the site's final design.The sitemap was created based on the information gathered in the previous phase. This is the Cisin software website sitemap:
Sitemaps describes the relationships between your important sections. This representation can help you understand the usability of your final product. This representation can help you see the "relationships" between pages on a website. You can then assess how easy it will be for end-users to find the information they need if they start at the main page. Sitemaps are created to make websites easy to navigate and user-friendly.
Sitemaps are useful for understanding the structure of a website, they do not display user interface. Before you begin to code or work on a design, you may need to get approval from the customer to ensure everything is in order before you move on to the next stage of development. In this instance, either a mockup or wireframe is created. A wireframe is a visual representation of the user interface you will make. It doesn't have any design elements like logos or colours. It only describes features that will be added and where they are located. It is a production sketch that is barebones and unartful.
Any mockup can be used for this purpose. Another important part is to choose the technology stack:programming languages, frameworks, CMS, etc.
Estimated Time: Between 2 and 6 Weeks
Step 3.
Your website will take shape during the design phase. This is where all visual content, such as photos, videos, and images, is created. It is essential to use all of the information collected in the first phase. When designing a product, it is essential to keep in mind the customer and target audience.
A website layout results from the work of a designer. You can choose to draw a sketch or create a full-blown graphic design. Layouts are used to visualize the basic functionality of the information structure and communicate its intent. Layouts can include colors, logos, and images. They also provide a glimpse into the future product.
The customer can then review the layout and give you feedback. You can change certain aspects of the design if the customer isn't satisfied. Repeat this process until your customer is satisfied.
Estimated Time: From 4 to 12 Weeks
Step 4.
It is typical for content writing and compiling to overlap with other stages in website creation. This makes it an important step. It is essential to write down the essence of what you want to convey to your audience and include calls to action. Writing content takes time and effort. This includes creating catchy headlines, editing, writing new text, compiling existing text, and so on. The client must provide all website content that can be migrated to the site before website development.
Estimated Time: Between 5 and 15 Weeks
Step 5.
This is the final step in creating a website. One can use graphic elements created in the previous stages to create a website. The home page is usually created first. Next, all sub-pages will be added according to the sitemap. To ensure that the server is capable of handling the setup and installation, CMS and frameworks should be used.
All static web page elements created during mockup and layout creation must be designed and tested. Next, you should add unique features and interactivity. This phase demands a deep understanding of each website development technology used in development.
If you need to install CMS plugins, CMS can be used for site creation. SEO (Search Engine Optimization) is another crucial step. Search Engine Optimization is the optimization and promotion of elements on a website that can help it rank higher in search engines results. Valid code is crucial for SEO.
Estimated Time: From 6 to 15 Weeks
Step 6.
Testing is an essential part of any process. To ensure that no broken links exist, every link needs to be tested. To find typos, you should test every form and script. To verify that your code conforms to current web standards, you can use code validators. If you require cross-browser compatibility, a valid code is required.
Once you have checked and rechecked your website, it is time to upload it onto a server. This is done using FTP (File Transfer Protocol). Once you have deployed your files, you need to run another final test to ensure everything is installed correctly.
Estimated Time: 2 to 4 Weeks
Step 7.
It is essential to understand that a website can be more than just a product. It is important to ensure that the website works as intended.
You can use the feedback system to identify potential problems that end-users may be facing. In this instance, the most critical task is to resolve the issue as quickly as possible. You might find that users prefer another website to fix the problem then you will.
Another important aspect is to keep your website current. Regular updates to a CMS will help you avoid bugs and reduce security risks. One can hire web development services for business needs.
Java Applications
Java(tm), customer-written code, can be initiated using a context menu (as a context item). The command profile editor defines the Application, and it runs on the topology console (a Java virtual computer).The context menu is created for the topology server using the CPEBATCH batch utility.
Java applications can either be resource-dependent or independent. Java applications dependent on a resource provide information about the selected resource. The com.tivoli.ihs.client.action.IhsResInfo This information is provided by the class, for instance. Java applications also provide information about the context menu items they are associated with. The com.tivoli.ihs.client.action.IhsCmdInfo This is illustrated by class. Java applications extend the functionality of the IhsJavaApplicationAdapter class.
Once the Application is launched, it can access all Java services and certain topology console services. It also has access to any other customer or third-party services. Any of the commands exits available from the topology server can be used to generate a command and issue it.
How to Create a Web Application using Java
How to Create a Java Web Application StackOverflow and Statistics show that Java is the most popular programming language for building web apps. Java is an object-oriented, high-level programming language. It has minimal dependencies. Java has been loved by programmers for more than 20 years.
Java applications can be compiled into binary code and run on any JVM (Java Virtual Machine) regardless of their operating system or architecture. This allows them to be portable. Java also offers JSP and Servlet technologies, which enable developers to easily create and deploy web applications on the server. Java, like other languages, has frameworks such as Spring and Hibernate, which simplify the process of developing web applications.
Before we get into how to create a Java web application, let's first understand some concepts.
Defining Java Web Application Technologies
While there are many technologies that can be used to create web applications using Java, developers tend to use a handful of them most often.
Java IDE
An integrated development environment in Java is called an IDE. It provides tools such as a code editor, debugger, compiler, and interpreter for web app development.
Java Servlet API
The Java servlet API is a set of programs that runs on web servers or application servers. Servlet APIs can process requests from web servers, create replies, and then send them back to the web server.
To create web applications, Java uses Servlets. To build a Java Servlet, you will need the Servlet API. This API consists of javax.servlet.http and javax.servlet.http. These contain all necessary classes and interfaces.
JavaServer pages (JSP)
Java Server Pages, or JSP, is a technology that makes it easier to develop dynamic web apps. Developers can also add servlet code fragments directly to the text. JSP is static data. It can be expressed in different text-based formats. JSP elements determine how dynamic content will be created.
JSP Standard Tag Library
JSTL includes all the functionality of JSP-based applications. JSTL allows you to use a standard set of tags rather than combining tags from different vendors. This standardization will enable you to deploy applications on any JSTL-supporting JSP container.
JSP Standard Tag Library also has conditional tags, iterators, and tags to manage the control flow. These tags can access databases using SQL and modify XML documents.
JavaServer Faces
The technology known as JavaServer Faces, or Jakarta Server Faces, consists of an API set that represents and controls user interface elements. The JSF Interface is expressed within a JSP webpage through a JSP custom tag library. Java Server Faces was created with flexibility in mind. Although it leverages common web tier and UI features, it does not impose any restrictions on developers in terms of protocol, device, or language.
Java Server Faces' architecture clearly separates presentation logic and application code, making it easier to connect the two.
JDBC
Java Database Connectivity API (JDBC API) provides universal access to data. Developers can access any data source, from flat files to relational databases to spreadsheets, using the JDBC API. Java can connect to, manipulate, and get data from the database using two packages, java.sql or javax.sql.
Java Persistence API
Java Persistence API provides an object/relational map facility that allows developers to manage relational data in Java web apps. JPA defines the object-relational map and standardizes them using XML annotations or XML to map objects into database tables.
JAX
Java API for XML Processing, or JAXP, allows you to process XML documents using Simple API for XML (Document Object Model), Extensible Stylesheet Language Transformation, and Document Object Model. You can also use namespaces to work with schemas as developers.
How to create a web application using Java?
- How to Create a Java Web App? It is essential to properly install Java, IDE Netbeans, or Eclipse for code writing and Server Tomcat as a web container for Servlet and Database (MySQL, Oracle, or Oracle) before you can create any web app.
- Tomcat may be set up with Eclipse for simple development and deployment. To find the Tomcat version, go to Eclipse Preferences and choose Server Runtime Environments. The location of the apache.mcat directory and the JRE details will be used to establish the runtime environment.Go to server's interface and create a server.. On our Tomcat server, we can now generate and launch the first Servlet.
- Select File>new > Dynamic Web Project in the Eclipse IDE. Next, input the default project location settings and the project name FirstServletProject. Next, check the box next to "Generate web.xml deployment description" > click "Finish."
- To create the Servlet, click File> New > Server and then click the Finish button. This will generate the skeleton code for the Servlet.
- After the Servlet has been created, it's time to add HTML using the GET method to invoke the HTTP request as below. Finally, run the Servlet.
- When we run our Servlet, it will display many errors due to the servlet API jar file not being added. We will add the jar file to our project by right-clicking it and then clicking on the Configure Build Path >Add External JARs option.
- You can then navigate to the directory that contains the server, select the servlet.api.jar File and click open to continue. Click on Apply and Close to add the jar to your project.
- While servlets can be useful in the beginning, it is difficult to understand and maintain large responses that contain dynamic data. JSPs were created to address this problem.
- JSP technology can be used server-side. It has the same features as HTML and can add dynamic content as required. JSPs look a lot like HTML and can be used to present data.
- To run the app, you will need to right-click on it and choose Run-> Run on Server option. The app will take some time to load. However, the output when using JSP/Servlet file will still be the same: "Hi there!" with the date and the time.
Java Application Development Process
- When developing Java(tm), follow these steps: Modify your applications as a guide. You can use one of the Java application examples
- You can modify the example to suit your needs
- Your Application can be packaged, compiled, and deployed
- Allow the Java application to run
The following steps used to test the Java application:
- Log in to the server with the new code
- Display Java application in the context menu
- Verify that the menu item is functioning accurately by selecting it
- To diagnose problems, you can enable service tracing options if necessary
