  1. Apache Tomcat Web Server MOHD NORFAIZI MIHSANY (A91391)

  2. Web Server • Used application server locate at technician room. • 202.185.47.240

  3. Architecture

  4. Server Setup Step by Step • Download and install the Java Software Development Kit (SDK). • Download Server • Configure the Server • Set up Development Environment • Test

  5. Download and Install Java Software Development Kit (SDK) • http://java.sun.com/j2se/1.4.2/index.jsp • Download the setup. • Install the SDK.

  6. Download a Server • Apache Tomcat, Macromedia JRun, Jetty, Microsoft IIS, iPlanet/Sun ONE Server and Apache Server. • Apache Tomcat 4.0 (http://jakarta.apache.org/tomcat) was used for this project. • Apache Tomcat 4.0 is the official reference implementation for Servlet 2.3 and JSP 1.2. • It’s entirely free and has complete source code available.

  7. Configuring Apache Tomcat • Setting the JAVA_HOME variable. • Specifying the server port. • Enabling servlet reloading. • Enabling the ROOT context. • Turning on the invoker servlet. • Increasing DOS memory limits (older windows). • Setting CATALINA_HOME (optional).

  8. Setting the JAVA_HOME Variable • Right click My Computer. • Select Properties. • Select Advance. • Select Environment Variable. • Add JAVA_HOME value and click OK. • Another way by edit install_dir/bin/catalina.bat and insert this line set JAVA_HOME=C:\J2sdk1.4.0

  9. Specifying the Server Port • By default, Apache Tomcat used port 8080. • Modifying the port number involves editing install_dir/conf/server.xml.

  10. The original element will look something like this : <Connector className=“org.apache.coyote.tomcat4.CoyoteConnector” port=“8080” minProcessors=“5” maxProcessors=“75” …. /> After <Connector className=“org.apache.coyote.tomcat4.CoyoteConnector” port=“80” minProcessors=“5” maxProcessors=“75” …. />

  11. Enabling Servlet Reloading • To turn on servlet reloading, edit install_dir/conf/server.xml. • Find <!-- Define properties for each web application. … …. --> • Insert following line just below it <DefaultContext reloadable=“true” />

  12. Enabling the ROOT Context • Edit install_dir/conf/server.xml. • Uncomment the following line <Context path=“” docBase=“ROOT” debug=“0” />

  13. Turning On the Invoker Servlet • Edit install_dir/conf/web.xml. • Uncomment following line <servlet-mapping> <servlet-name>invoker</servlet-name> <url-pattern>/servlet/*</url-pattern> </servlet-mapping>

  14. Increasing DOS Memory Limits • For old version of Windows like windows 98. • Right click install_dir/bin/startup.bat. • Select properties. • Select memory and change the Initial Environment from Auto to at least 2816.

  15. Setting CATALINA_HOME • Right click My Computer. • Select Properties. • Select Advance. • Select Environment Variable. • Add CATALINA_HOME value and click OK.

  16. Test your Setup • Double click on install_dir/bin/startup.bat. • Open browser and enter Http://localhost

  17. Using The Default Web Application • Packageless Servlet code : install_dir/webapps/ROOT/WEB-INF/classes URL : http://host:port/servlet/ServletName • Packaged Servlet code : install_dir/webapps/ROOT/WEB-INF/ classes/packagename URL : http://host:port/servlet/packageName.ServletName

  18. Using The Default Web Application • Packaged Beans and Utility Classes install_dir/webapps/ROOT/WEB-INF/ classes/packageName • JAR Files install_dir/webapps/ROOT/WEB-INF/lib

  19. Using The Default Web Application • HTML and JSP (Not In Subdirectories) code : install_dir/webapps/ROOT URL : http://host:port/filename • HTML and JSP (In Subdirectories) code : install_dir/webapps/ROOT/directoryName URL : http://host:port/directoryNme/filename

  20. Servlet and JSP APIs • Install_dir/webapps/tomcat-docs/servletapi/index.html

  21. CLASSPATH • Set CLASSPATH in Environment Variable. • Have it include installdir/common/lib/servlet.jar. • For compile Servlet application.
