Tomcat

Apache Tomcat is an open source software implementation of the Java Servlet and JavaServer Pages technologies.

Installation on Slackware

• cd ~/Downloads

• wget http://mirrors.fe.up.pt/pub/apache/tomcat/tomcat-7/v7.0.57/bin/apache-tomcat-7.0.57.tar.gz

• su
• cp apache-tomcat-7.0.57.tar.gz /opt
• cd /opt
• tar xvzf apache-tomcat-7.0.57.tar.gz
• chown vitor * -R
• chgrp users * -R
• exit

Start Tomcat

• cd /opt/apache-tomcat-7.0.57/bin/
• #./startup.sh
• ./catalina.sh start

• http://localhost:8080/

Add admin user

• cd /opt/apache-tomcat-7.0.57/conf

Edit tomcat-users.xml

  <role rolename="admin"/>
  <role rolename="manager"/>
  <role rolename="manager-gui"/>
  <user username="admin" password="12345678" roles="admin,manager,manager-gui"/>

• ./shutdown.sh
• ./startup.sh

WebApps location

• /opt/apache-tomcat-7.0.57/webapps

A WAR file can be copied or exploded in the webapps folder.

Sample App

Download http://localhost:8080/docs/appdev/sample/sample.war and deploy in the webapps folder. After the deploy the WAR file is exploded.

Configuration values in web.xml for WAR file

Adapted from http://stackoverflow.com/questions/372686/how-can-i-specify-system-properties-in-tomcat-configuration-on-startup

   1 <env-entry>
   2     <env-entry-name>SMTP_PASSWORD</env-entry-name>
   3     <env-entry-type>java.lang.String</env-entry-type>
   4     <env-entry-value>abc123ftw</env-entry-value>
   5 </env-entry>

Get values in code:

   1 // Obtain our environment naming context
   2 Context initCtx = new InitialContext();
   3 Context envCtx = (Context) initCtx.lookup("java:comp/env");
   4 
   5 // Look up our data source
   6 String s = (String)envCtx.lookup("SMTP_PASSWORD");

Change HTTP from port 8080 to port 8081 and AJP from 8009 to 8010

Edit file conf/server.xml

Change the HTTP Connector from 8080 to 8081. Change AJP1.3 connector from 8009 to 8010.

   1     <Connector port="8081" protocol="HTTP/1.1"
   2                connectionTimeout="20000"
   3                redirectPort="8443" />
   4 
   5     <!-- Define an AJP 1.3 Connector on port 8009 -->
   6     <Connector port="8010" protocol="AJP/1.3" redirectPort="8443" />

Logging custom logger

Create logger

   1 java.util.logging.Logger logger = java.util.logging.Logger.getLogger("TestLogger");
   2 logger.info("Test message info level"); // logs in info level
   3 

Configure the logging properties in <Tomcat>/conf/logging.properties

handlers = (...),<digitToHandler><LoggerName>.org.apache.juli.FileHandler
handlers = (...),5TestLogger.org.apache.juli.FileHandler

5TestLogger.org.apache.juli.FileHandler.level = FINE
5TestLogger.org.apache.juli.FileHandler.directory = ${catalina.base}/logs
5TestLogger.org.apache.juli.FileHandler.prefix = TestLogger.

# configure logger level and handler
TestLogger.handlers=5TestLogger.org.apache.juli.FileHandler
TestLogger.level=INFO

When no custom handler is defined the Logger outputs to console and to catalina.out in Tomcat 7.0.X. The root logger defines its set of handlers using .handlers.

# default handlers in tomcat 7.X
.handlers = 1catalina.org.apache.juli.FileHandler, java.util.logging.ConsoleHandler

The file logging properties file is set with the system property java.util.logging.config.file (-Djava.util.logging.config.file).
