An introduction to Tomcat servlet interactions Although its flexible configuration and interoperability with supporting technologies have enabled Apache Tomcat to act as a web application server in many circumstances, Tomcat is primarily a Java servlet container. See full list on

Make sure you're not running a TCP server on port 8080 (the default Tomcat HTTP server socket port), nor on TCP port 8005 (the default Tomcat shutdown server socket port). Try running telnet localhost 8080 and telnet localhost 8005 to see if any existing server accepts a connection, just to be sure. The Tomcat manager provides a quick way to check our server's status by displaying how many HTTP threads are active, the storage allocation in the various memory pools plus other helpful data. To learn how to check the status of the Apache Tomcat Server, follow these six steps: Start the Tomcat server. Tomcat SSL or HTTPS Configuration Example Secure Socket Layer (SSL) is a secure transfer protocol used for communication on the Internet using cryptographic methods. The main purpose of the SSL protocol is to guarantee that no one can tamper with the communication between a browser and the server where the web application is deployed.

1. Overview

Spring Boot web applications include a pre-configured, embedded web server by default. Cisco vpn anyconnect client download free. In some situations though, we'd like to modify the default configuration to meet custom requirements.

In this tutorial, we'll look at a few common use cases for configuring the Tomcat embedded server through the file.

2. Common Embedded Tomcat Configurations

2.1. Server Address and Port

The most common configuration we may wish to change is the port number:

If we don't provide the server.port parameter it's set to 8080 by default.

In some cases, we may wish to set a network address to which the server should bind. In other words, we define an IP address where our server will listen:

By default, the value is set to which allows connection via all IPv4 addresses. Setting another value, for example, localhost – – will make the server more selective.

2.2. Error Handling

By default, Spring Boot provides a standard error web page. This page is called the Whitelabel. It's enabled by default but if we don't want to display any error information we can disable it:

The default path to a Whitelabel is /error. We can customize it by setting the server.error.path parameter:

We can also set properties that will determine which information about the error is presented. For example, we can include the error message and the stack trace:

Our tutorials Exception Message Handling for REST and Customize Whitelabel Error Page explain more about handling errors in Spring Boot.

2.3. Server Connections

When running on a low resource container we might like to decrease the CPU and memory load. One way of doing that is to limit the number of simultaneous requests that can be handled by our application. Conversely, we can increase this value to use more available resources to get better performance.

In Spring Boot, we can define the maximum amount of Tomcat worker threads:

When configuring a web server, it also might be useful to set the server connection timeout. This represents the maximum amount of time the server will wait for the client to make their request after connecting before the connection is closed:

We can also define the maximum size of a request header:

The maximum size of a request body:

Or a maximum size of the whole post request:

2.4. SSL

To enable SSL support in our Spring Boot application we need to set the server.ssl.enabled property to true and define an SSL protocol:

We should also configure the password, type, and path to the key store that holds the certificate:


And we must also define the alias that identifies our key in the key store:

2.5. Tomcat Server Access Logs

Apache Tomcat 7

Tomcat access logs are very useful when trying to measure page hit counts, user session activity, and so on.

To enable access logs, simply set:

We should also configure other parameters such as directory name, prefix, suffix, and date format appended to log files:

3. Conclusion

In this tutorial, we've learned a few common Tomcat embedded server configurations. To view more possible configurations, please visit the official Spring Boot application properties docs page.

As always, the source code for these examples is available over on GitHub.

Apache vs Tomcat Server

Apache Server and Tomcat Server are two of the products developed by Apache Software Foundation. Apache is a HTTP web server, while Apache Tomcat is a Servlet container environment. However, Tomcat server comes with its own HTTP server component. Apache and Tomcat are often confused to be the same server due to the similarity in their names. Although they are developed by the same organization, they are not bundled together. Usually, these two products are used together in enterprises for serving web sites.

What is Tomcat Server?

Tomcat (also known as Apache Tomcat or Jakarta Tomcat) provides a “pure java” HTTP web server environment that can be used to run Java code. It is a Servlet container developed by Apache Software Foundation, which is offered as an open source product. Sun Microsystems’s Java Servlet and JSP (Java Server Pages) specifications are implemented by Tomcat. Apache Tomcat can be configured using XML configuration files (although tools for configuration and management are included with the server). Tomcat 7.0 is the latest stable version of Tomcat, which introduced many new features over its previous version.

Apache started working on Apache 7.0 as early as January, 2009. But, it was announced stable after 2 years (in January, 2011). Tomcat 7.0.6 is the first Tomcat 7 stable release. Tomcat 7.0 was built upon the improvements introduced in the earlier version and implements Servlet 3.0 API, JSP 2.2 and EL 2.2 specifications. Improvements offered by Tomcat 7.0 are detection/prevention of memory leaks in web applications, improved security for Manager/Host Manager, CSRF (Cross-Site Request Forgery) protection, ability to include external content in applications directly and cleaned up code (including refactoring of connectors and lifecycles).

What is Apache Server?

Tomcat Http Connector Server.xml

Apache (or Apache Server) is a HTTP web server developed by Apache Software Foundation. Apache Server is said to have played a major role in the rapid expansion of the World Wide Web. It already has more than 100 million websites implemented using it. It is considered the most popular HTTP server. Currently, it serves 2/3 of all web sites in the world, including 2/3 of the million busiest web sites. Apache is a cross-platform server, which mainly supports Unix-like systems such as UNIX, FreeBSD, Linux and Solaris. It can also be run on Mac OS X and Microsoft Windows as well. Robert McCool is the original author of Apache, and its initial release was in 1995. Its current stable release is 2.2.19, which was released on 22 May, 2011. Apache is open source software written in C language and licensed under Apache license 2.0.

Apache’s core functionality is extended using a variety of features implemented as compiled modules. Apache supports Perl, Python and PHP and a variety of authentication modules including mod_access, mod_auth and mod_auth_digest. Apache web server also supports SSL (Secure Sockets Layer) and TLS (Transport Layer Security). Further, a proxy module, a rewrite engine, a logging system and a filtering system are provided by Apache. AWStats or W3Perl can be used to analyze the Apache logs. Mod_gzip is the compression method provided by Apache server. Open source intrusion detection/prevention engine, ModSecurity is also included in Apache.

Tomcat Http Server Status

What is the difference between Apache and Tomcat Server?

– Apache server is a HTTP web server, while Apache Tomcat server is primarily an application server that is used to run Java code.

– Apache is written in C, while Tomcat is written in Java.

– Apache is used for serving static content, while Tomcat is used mainly for dynamic content such as Java Servlets and JSP files.

– Typically, Apache is found to be faster than Tomcat when it comes to serving static content.

– Apache is also more configurable and robust than Tomcat.

– However, if you are serving dynamic content on your site, Tomcat is the only option out of these two servers, as Apache can only serve static content like HTML pages.
