How to install Apache Tomcat on Windows. Tomcat is a web server developed by Apache. This web server helps you to run web applications written with JSP as a website. To test your software you need to create a local website in your system and put your programs in it. In this article, you will be taught how to install Apache Tomcat on Windows.
Menawhile, I have tried to copy the tomcat folder from the production server (I was working on my local copy) and now at least the application is asking for the credentials. Although I have set them in the users DB, I get a 500: java.lang.NullPointerException org.apache.catalina.realm.RealmBase.authenticate(RealmBase.java:340) – Pierpaolo Jun.
If you have previously written web software or are a little familiar with network concepts, you know that the IP address of our system is always 127.0.0.1. Also the default domain address it refers to is Localhost.
This means that our local website will be accessible in our system by entering the address http: // localhost: port where the port is the port number of our web server. (Of course, it is not necessary to enter the port number for port 80).
To run Apache Tomcat, you must have Java JDK installed on your system. So before you start installing tomcat, it is better to install JDK on your system and set the JAVA_HOME and PATH variables for it.
If you do not know how to install and configure JDK, you can learn it from the link below:
There are several ways to install Tomcat, such as downloading a Zip file or installing XAMP Server. Here we use the Exe file download method.
1. In the first step, download the Tomcat installation exe file from the following link:
2.After downloading the installation file, run it and go to the next page by clicking Next.
3.Click I Agree to confirm the agreement.
4.Select the components as shown below and go to the next page.
5. Enter your favorite ports for the software.
Remember that if you use another port number instead of 8080 in the Http Port section, you must enter Localhost:portnumber instead of Localhost:8080 to access your site.
Note:Portnumber is the port number you entered during installation.
6. Enter the JRE installation path that you installed on your system.
The software itself tries to find the path and show it here, so if it is correct, you do not need to change it.
7. Follow the rest of the steps to install the software.

8. By entering the address http://Localhost:8080, you should see the default Tomcat page, which is as follows for the version I installed:
9. To test the correct execution of Tomcat, go to the root address of Tomcat software and create a folder called test (in lower case). Usually in Windows, the root address of Tomcat software is as follows:
Tomcat Installation Path/WebApps/Root/
For example for my system:
C:Program FilesApache Software FoundationTomcat 8.0webappsROOT
10.Because we are creating a server for Test here, if you do not have access to create a file in the test folder, right-click on it. Then select the properties and click on Security and click Edit. Inside Users, select Edit and check all the options in the Allow column.
11. Now create a text file named Index.jsp (in lower case) in the test folder and type the following code inside it:
12. Make sure the file is index.jsp and the .txt format is not added to the end. In addition, SP Jfiles can be edited with notepad ++ or Windows Notepad:
<% out.write(“eldernode.com”); %>
13.Now go to the following address and see the result:
http://localhost:8080/test/
The result should be a blank page with the text eldernode.com written on it.
Dear user, we hope you would enjoy this tutorial, you can ask questions about this training in the comments section, or to solve other problems in the field of Eldernode training, refer to the Ask page section and raise your problem in it as soon as possible. Make time for other users and experts to answer your questions.
Goodluck.
Apache Tomcat is a mandatory component required to run the ESMC Web Console.
Important If a custom version of Apache Tomcat is installed (manual installation of the Tomcat service), the subsequent ESMC Web Console upgrade via the All-in-one installer or via Components Upgrade Task is not supported. |
Follow these instructions to upgrade Apache Tomcat manually (if you do not have the latest ESMC All-in-one installer):
1.Ensure that Java/OpenJDK is up to date.
Warning Starting January 2019, Oracle JAVA SE 8 public updates for business, commercial or production use require a commercial license. If you do not purchase a JAVA SE subscription, you can use this guide to transition to a no-cost alternative and install one of listed supported Java editions. |
Important •64-bit Java is required. •If you have multiple Java versions installed on your system, we recommend that you uninstall older Java versions (the oldest supported version is Java 8) and keep only the latest version of Java. |
2.Check to see which version of Apache Tomcat is currently available.
a.Navigate to the Apache Tomcat installation folder:
C:Program FilesApache Software Foundation[Tomcat folder ]
b.Open the RELEASE-NOTES file in a text editor and check the version number (for example 7.0.90).
c.If a more recent supported version is available, perform an upgrade.
1.Stop the Apache Tomcat service: Navigate to Start > Services > right-click the Apache Tomcat service and select Stop.
Close Tomcat7w.exe if it is running in your system tray.
2.Back up the following files:
C:Program FilesApache Software Foundation[Tomcat folder ].keystore
C:Program FilesApache Software Foundation[Tomcat folder ]confserver.xml
C:Program FilesApache Software Foundation[Tomcat folder ]webappseraWEB-INFclassesskeseterag2webconsoleservermodulesconfigEraWebServerConfig.properties
If you are using a custom SSL certificate store in the Tomcat folder, also back up that certificate.
3.Uninstall the current version of Apache Tomcat.
4.Delete the following folder if it is still present on your system:
C:Program FilesApache Software Foundation[Tomcat folder ]
5.Download the latest supported version of the Apache Tomcat installer file (32-bit/64-bit Windows Service Installer) apache-tomcat-[version].exe from https://tomcat.apache.org.
6.Install the newer version of Apache Tomcat that you downloaded:
•In case more Java versions are installed, select the path to latest Java during the installation.
•When you are finished, deselect the check box next to Run Apache Tomcat.
7.Restore .keystore, server.xml, and custom certificates to their original location.
8.Make sure that HTTPS connection for Apache Tomcat for ESMC Web Console is set up properly.
9.Deploy the ESMC Web Console (Web Console installation - Windows).
10. Restore EraWebServerConfig.propertiesto its original location.
11. Run Apache Tomcat and set a correct Java VM:
a)Navigate to the folder C:Program FilesApache Software Foundation[Tomcat folder ]bin and run Tomcat9w.exe.
b)In the General tab set Startup Type to Automatic and press Start.
c)Click the Java tab, make sure Use default is deselected and Java Virtual Machine includes the path to jvm.dll file(see illustrated Knowledgebase instructions), and then click OK.
12.Connect to the ESMC Web Console and ensure that the program works correctly.
•If you are unsuccessful in setting up an HTTPS connection for Apache Tomcat, you can skip this step and use an HTTP connection temporarily.
•If the upgrade of Apache Tomcat fails, install your original version and apply the configuration from step 2.
