Environment Setup for Struts

Introduction🤔

Apache Struts 2 is a sophisticated, flexible framework for developing enterprise-class Java web applications. This framework is intended to simplify the whole development cycle, from application creation through deployment and maintenance over time.

This blog will go through setting up a development environment so that you can start working with Struts 2.

Environment Setup for Struts💻

We need to follow the steps given below to set up a development environment to start working with struts 2.

1. Setup Java Development Kit (JDK)
2. Setup Apache Tomcat
3. Setup Eclipse (IDE)
4. Setup Struts2 Libraries

Are you ready to discuss the above steps in detail❓

Setting up Java Development Kit🧑‍🔧

We can get the most recent version of the SDK from Oracle's Java SE Downloads page. In the downloaded files, follow the instructions to install and configure the setup. Finally, configure the PATH and JAVA HOME environment variables to point to the directory containing java and javac, usually java_install_dir/bin and java_install_dir, respectively.

If you're using Windows and installed the SDK in C:jdk1.5.0 20, add the following lines to your C:autoexec.bat file.

set PATH = C:\jdk1.5.0_20\bin;%PATH%
set JAVA_HOME = C:\jdk1.5.0_20

Alternatively, on Windows NT/2000/XP,

• Right-click the My Computer and select Properties, Advanced, and Environment Variables. You would then adjust the PATH value and click the OK button.
   
• If the SDK is installed at /usr/local/jdk1.5.0 20 and you use the C shell on Unix (Solaris, Linux, etc.), add the following to your .cshrc file.

On Unix, if the SDK is installed at /usr/local/jdk_version_code and we utilise the C shell, add the following to your.cshrc file.

setenv PATH /usr/local/jdk_version_code/bin:$PATH
setenv JAVA_HOME /usr/local/jdk_version_code

Alternatively, if you utilise an Integrated Development Environment (IDE) such as Borland JBuilder, Eclipse, IntelliJ IDEA, or Sun ONE Studio, build and execute a primary application to validate that the IDE knows where you installed Java; otherwise, follow the IDE's setup instructions.

Setting up Apache Tomcat🧑‍🔧

We can get the most recent version of Tomcat at Apache Tomcat. After downloading the installation, unpack the binary package into an appropriate location.

By visiting http://localhost:8080/, you can access Tomcat's default web apps. If everything is in order, the following result should be displayed.

Use the following instructions on a Unix (Solaris, Linux, etc.) system to start Tomcat.

$CATALINA_HOME/bin/startup.sh

or

/usr/local/apache-tomcat-6.0.33/bin/startup.sh

Setting up Eclipse IDE💻

Eclipse must be installed. Get the most recent Eclipse binaries from eclipse’s download page. After downloading the installation, unpack the binary package into an appropriate location.

The following result should be displayed if all goes well after a successful startup.

Use the following instructions to launch Eclipse on a Unix (Solaris, Linux, etc.) workstation.

$/usr/local/eclipse/eclipse

Setting up Struts2 Libraries💻

If everything goes fine, you can now proceed to configure your Struts2 framework. The basic procedures for downloading and installing Struts2 on your PC are as follows.

• Choose whether to install Struts2 on Windows or Unix, and then go to the next step to download the .zip file for Windows and the .tz file for Unix.
   
• Struts2 binaries may be downloaded at https://struts.apache.org/download.cgi 
   
• When you unzip the downloaded file, you will see the following directory structure under C:struts-version_code.

The second step is to extract the zip file to a convenient location.

Note -  If you do not correctly configure your CLASSPATH variable, you will have problems while launching your programme.
