Download Tomcat

• http//ftp.cuhk.edu.hk/pub/packages/apache.org/tom
  cat/tomcat-5/v5.5.28/bin/apache-tomcat-5.5.28.zip
• Put under C\ and unzip to C\apache-tomcat-5.5.28
  

3
Starting and Stopping Tomcat

• In command line window, set JAVA_HOMEc\Program
  Files\Java\jdk1.5.0_03 (depends on your jdk
  directory name, for example, maybe yours is
  jdk1.6.x_xx)
• C\apache-tomcat-5.5.28\bingtstartup
• C\apache-tomcat-5.5.28\bingtshutdown
• Open a browser and type in
• http//localhost8080

Web Application Directory Structure
webapps
liangweb
Static files, such as HTML files and JSP files in
the directory that is the document root of your
Web Application
.html
.jsp
WEB-INF
web.xml
classes
.class
Packages (e.g., chapter35)
.class
lib
.jar
5
Compiling Servlets

• Set classpathclasspathc\apache-tomcat-5.5.28\
  common\lib\servlet-api.jar
• Create directory
• c\apache-tomcat-5.5.28\webapps\liangweb\WEB-INF\
  classes
• Copy slide/book/FirstServlet.class into
  c\apache-tomcat-5.5.28\webapps\liangweb\WEB-INF\c
  lasses

6

• Download www.cs.armstrong.edu/liang/intro6e/supple
  ment/web.xml to
• c\apache-tomcat-5.5.28\webapps\liangweb\WEB-INF
  
• Run by typing
• http//localhost8080/liangweb/FirstServlet

7
For JDBC Programs

• Create a directory liangweb/META-INF
• Create a file context.xml with the following
  content
• ltContext path"/liangweb" docBase"liangweb"
  debug"5 reloadable"true" crossContext"true"gt
• ltResource name"jdbc/TestDB" auth"Container
  type"javax.sql.DataSource driverClassName"com.m
  ysql.jdbc.Driver url"jdbcmysql//localhostData
  baseNamejavabook" username"scott"
  password"tiger"
• maxActive"300" maxIdle"30" maxWait"10000" /gt
• lt/Contextgt

8

• Put mysqljdbc.jar under apache-tomcat-5.5.28/commo
  n/lib/
• You have to startup your MySQL database (or MySQL
  service) with net start mysql

9
Run JDBC Servlet Programs

• Under slide/book, you can find SimpleRegistration.
  html and SimpleRegistration.class. Do the
  following tasks
• Put the html file under apache-tomcat/webapps/lian
  gweb. Put the class file under apache-tomcat/webap
  ps/liangweb/WEB-INF/classes.
• 2. Startup tomcat, and type the URL
  http//localhost8080/liangweb/SimpleRegistration.
  html in a browser.
• 3. Test whether you can successfully insert the
  record you input in the form into the database.
• 4. Before you do that, you have to create a table
  "Address" with the lastname, firstname,..., zip
  fields in your MySQL database.
• You can also test Registration.html/class,
  RegistrationWithCookie.html/class and
  RegistrationWithHttpSession.html/class in a
  similar way.

Part II JSP

• Startup tomcat
• Copy the following jsp files to
  apache-tomecat\webapps\liangweb and run
• CurrentTime.jsp
• http//localhost8080/liangweb/CurrentTime.jsp
• Factorial.jsp
• http//localhost8080/liangweb/Factorial.jsp
• ComputeLoan.html and ComputeLoan.jsp
• http//localhost8080/liangweb/ComputeLoan.html

11

• ComputerLoan1.html (modify this file according to
  Page 31 of Chapter 40 ppt)
• Copy Loan.java to liangweb\WEB-INF\classes\chapter
  35\
• Compile it into Loan.class
• http//localhost8080/liangweb/ComputerLoan1.html
• Do the same for ComputerLoan2.html Loan.class
• Do the same for TestBeanScope.jsp Count.class
• Do the same for FactorialBean.jsp
  FactorialBean.class
• Do the same for NewFactorialBean.jsp
  NewFactorialBean.class

12
The JDBC Example

• Copy DBLogin.html, DBLoginInitialization.jsp,
  Table.jsp, BrowseTable.jsp to liangweb
• Copy DBBean.java to liangweb/WEB-INF/classes/chapt
  er35 and compile it to DBBean.class
• Startup MySQL
• Run http//localhost8080/liangweb/DBLogin.html
