Apache Tomcat Server is widely used in Java. The basic use of Apache Tomcat Server in Java is to execute Java servlets and render Java Server Pages. Apache Tomcat Server plays an important role in execution of Java Server Pages coding.
The various uses of Apache Tomcat Server are discussed briefly in the article, or you may join our java training program to learn the use of Apache tomcat server in java with professional instructors help.
What Is Apache Tomcat Server?
Apache Tomcat Server is developed by Apache software foundation. It is an open source web server and is used as Java servlet container. The Java Servlet and Java Server Pages specifications provided by Sun Microsystems is implemented by the Apache Tomcat Server and it also provide a perfect environment for running Java programs.
Only a single operating system process is required to run Tomcat in a simplest configuration. The operating system firstly runs a Java Virtual Machine (JVM). HTTP requests that are sent from the browser to Tomcat are processed in a separate thread in the Tomcat process.
Although Apache Tomcat includes management and configuration tools, it can also be configured by using the XML configuration files. The configuration can be done by suing the XML configuration files.
In other words, Apache Tomcat server can also be seen as a development server on your computer which used for testing applications that are build using Java Server faces 2, servlets or Java Server Pages and other Java-based dynamic web technologies.
No matter whichever deployment server is used, a standalone server is required for the purpose of development. The best way to use Apache Tomcat Server is through any IDE such as Eclipse.

How To Use Apache Tomcat Server ?
Apache Tomcat Server should not be deployed manually, instead, it is advised to use Apache Tomcat Server through Eclipse or NetBeans or any other IDE. Here is a small guide on how to install and use Apache Tomcat Server with Eclipse on your computer.
- Installing Java.
The first and foremost thing is to ensure that Java is installed in your system. If not already done, then start with installing the latest version of Java.
2 Download Apache Tomcat.
Then you need to download Apache Tomcat and then unzip it.
3. Install Eclipse.
The third step is to download and install Eclipse. You need to download the Java EE version of Eclipse.
4. Running Apache Tomcat Server through Eclipse.
Once Eclipse is installed, then Eclipse will be started. After starting Eclipse go to the workbench and click on Servers option at the bottom and right click on it. Then select New and then Server and then select the version of Tomcat that you want to use for which you might have to navigate through the Tomcat installation folder. This is how Apache Tomcat Server is introduced to Eclipse in Java.
5. Test the server.
After the introduction of Tomcat Server to Eclipse you can now test the Apache Tomcat Server within Eclipse.
6. Adjusting Eclipse preferences.
Eclipse comes with many customizations. With Eclipse, one can adjust colors, indentation styles, font size, import statement formats, etc.
For adjusting preferences in Eclipse, you need to set the location of JDK for which you need to go about as below: Window > preferences > Java > Installed JRE’s then make sure that you have JDK selected already. If not then click Add, after which you need to navigate to the JDK’s base folder i.e. the install location of the JDK.
Another customization that is frequently done with Eclipse is suppressing the redundant warnings re serialVersionUID on Serializable classes.
It is possible to serialize the HttpServletclass, but normally one does not sends any instances across the network or writes them on the disk, and the serialVersionUID field is normally not put by anybody in servlets. If every servlet in Eclipse is marked with an exception then one might get into the habit of ignoring warnings which is risky.
There is a rare possibility that the warning is not useful because majority of the times it is. Therefore, you need to go to Window > Preferences > Java > Compiler > Errors/Warnings and then expand Potential programming problems option after which you need to change the option of Serializable class without serialVersionUID to Ignore.
Therefore, these are the basic steps to use apache Tomcat Server in Java. It can be easily concluded from the given article that if you want to use Apache Tomcat Server in Java then you should use it through some IDE.
