This is a note that summarizes what I learned from workplace and self-study.

• Apache Tomcat

Prof. Wiki: Apache Tomcat(also referred to as Tomcat Server) implements several Java EE specifications including Java Servlet, JavaServer Pages(JSP), Java EL, and WebSocket, and provides a “pure Java” HTTP web server environment in which Java code can run.

• How to change character code

※ Implement if necessary. 

1) If characters are garbled when executing the following files, modify “C:\tomcat9\conf\logging.properties”. (About line 51)

Following file:

“C:\Tomcat9\bin\start-up.bat”
“C:\Tomcat9\bin\shutdown.bat”

Files to edit:

“C:\tomcat9\conf\logging.properties”

Edited content: (about line 51)

java.util.logging.ConsoleHandler.encoding = UTF-8

↓

java.util.logging.ConsoleHandler.encoding = SJIS

Before changing:

After changing:

• If you want to access http://localhost:8080/manager/html

※ Implement if necessary.

Example：

• user name: “admin”
• password: “pass”

1) Add the following to “C:\tomcat9\conf\tomcat-users.xml”. (About 18th line)

<role rolename="manager-gui"/>
<user username="admin" password="pass" roles="manager-gui"/>

Example：

<tomcat-users xmlns="http://tomcat.apache.org/xml"
              xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
              xsi:schemaLocation="http://tomcat.apache.org/xml tomcat-users.xsd"
              version="1.0">

↓

<tomcat-users xmlns="http://tomcat.apache.org/xml"
              xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
              xsi:schemaLocation="http://tomcat.apache.org/xml tomcat-users.xsd"
              version="1.0">
	<role rolename="manager-gui"/>
	<user username="admin" password="pass" roles="manager-gui"/>

2) Modify “C:\tomcat9\conf\tomcat-users.xml” as follows. (About line 40)
※ Change “must-be-changed” to “pass”.

Example：

  <role rolename="tomcat"/>
  <role rolename="role1"/>
  <user username="tomcat" password="<must-be-changed>" roles="tomcat"/>
  <user username="both" password="<must-be-changed>" roles="tomcat,role1"/>
  <user username="role1" password="<must-be-changed>" roles="role1"/>

↓

<role rolename="tomcat"/>
<role rolename="role1"/>
<user username="tomcat" password="pass" roles="tomcat"/>
<user username="both" password="pass" roles="tomcat,role1"/>
<user username="role1" password="pass" roles="role1"/>
