Apache Tomcat

This document describes the configuration of the Apache Tomcat server, which is needed for the Webservices of BlueSpice.

Installation

Linux

Install the latest version of the Apache Tomcat server in the package manager of your distribution. The package manager dissolves all dependencies and installs the required packages.  

Windows

Java

Apache Tomcat requires the Java Runtime Environment. If these is not already installed at your system, download (www.java.com) and install it. We recommend the 64 bit version for latest systems. 

Tomcat

Download the "32-bit/64-bit Windows Service Installer" from the Tomcat project website.  No modifications are necessary during the installation process. Confirm the single steps with "Next".

Installation Check

If the Apache Tomcat server has been installed and started correcly can be checked by calling up http://<hostname-oder-ip-des-servers>:8080. With a correct installation, the default page of the server will be displayed. 

Configuration

Now, two configuration files of the Tomcat server need to be adjusted: 

• context.xml
• server.xml

Those can - per default - be found at: 

• with Windows: C:\Program Files\Apache Software Foundation\Tomcat 8.5\conf
• with Linux: /etc/tomcatX (the "X" stands for the particular Tomcat version)

context.xml

Replace the line

<context>

with

<Context mapperContextRootRedirectEnabled="true">

server.xml

Please make sure that the complete block

<Connector port="8080" protocol="HTTP/1.1"
	... />

is as follows:

<Connector port="8080" protocol="HTTP/1.1"
	connectionTimeout="20000"
	URIEncoding="UTF-8"
	redirectPort="8443"
	address="127.0.0.1" />

Restart Tomcat

Restart the Tomcat server:

• Linux: service tomcatX restart (the "X" stands for the particular Tomcat version)
• Windows: See below: Restart Tomcat

Special features under Windows

Configure Tomcat

All of the following settings need to be done in the configuration interface of Tomcat. These can be found in the start menu under "Configure Tomcat".

Restart Tomcat

The restart can be performed in the first tab of the configuration interface. Stop and then start the service there. 

Setup Autostart

Tomcat will not automatically be started with Windows. This needs to be configured in the first tab, where you also start the service. Switch to "Automatic" under "Startup type" and save this changes with a click on "Apply". 

Particular Caution: Java Update

Tomcat requires Java. The path for this is firmly defined in Tomcat. Java, however, changes the installation path with every update. Those needs to be configured in Tomcat after every update to guarantee the functionality of Tomcat. 

To do this, switch to the tab "Java" and change the path to jvm.dll under "Java Virtual Machine" - normally this is
C:\Program Files\Java\<Pfad-zur-aktuellen-Java-Installation>\bin\server\jvm.dll.
