Download Tomcat
• http://ftp.cuhk.edu.hk/pub/packages/apach
e.org/tomcat/tomcat-5/v5.5.28/bin/apachetomcat-5.5.28.zip
• Put under C:\ and unzip to C:\apachetomcat-5.5.28
Starting and Stopping Tomcat
• In command line window, set JAVA_HOME=c:\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\bin>startup
• C:\apache-tomcat-5.5.28\bin>shutdown
• Open a browser and type in
http://localhost:8080
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
Compiling Servlets
• Set classpath=%classpath%;c:\apache-tomcat5.5.28\common\lib\servlet-api.jar
• Create directory
c:\apache-tomcat5.5.28\webapps\liangweb\WEB-INF\classes
• Copy slide/book/FirstServlet.class into
c:\apache-tomcat5.5.28\webapps\liangweb\WEB-INF\classes
• Download
www.cs.armstrong.edu/liang/intro6e/suppl
ement/web.xml to
c:\apache-tomcat5.5.28\webapps\liangweb\WEB-INF
• Run by typing
http://localhost:8080/liangweb/FirstServlet
For JDBC Programs
• Create a directory liangweb/META-INF
• Create a file “context.xml” with the following content
<Context path="/liangweb" docBase="liangweb" debug="5“
reloadable="true" crossContext="true">
<Resource name="jdbc/TestDB"
auth="Container“ type="javax.sql.DataSource”
driverClassName="com.mysql.jdbc.Driver
url="jdbc:mysql://localhost;DatabaseName=javabook"
username="scott" password="tiger"
maxActive="300" maxIdle="30" maxWait="10000" />
</Context>
• Put mysqljdbc.jar under apache-tomcat5.5.28/common/lib/
• You have to startup your MySQL database
(or MySQL service) with “net start mysql”
Run JDBC Servlet Programs
•
Under slide/book, you can find SimpleRegistration.html and
SimpleRegistration.class. Do the following tasks:
1. Put the html file under apache-tomcat/webapps/liangweb. Put the class file
under apache-tomcat/webapps/liangweb/WEB-INF/classes.
2. Startup tomcat, and type the URL
http://localhost:8080/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 apachetomecat\webapps\liangweb and run
• CurrentTime.jsp
http://localhost:8080/liangweb/CurrentTime.jsp
• Factorial.jsp
http://localhost:8080/liangweb/Factorial.jsp
• ComputeLoan.html and ComputeLoan.jsp
http://localhost:8080/liangweb/ComputeLoan.html
• ComputerLoan1.html (modify this file according to Page 31 of
Chapter 40 ppt)
• Copy Loan.java to liangweb\WEB-INF\classes\chapter35\
• Compile it into Loan.class
• http://localhost:8080/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
The JDBC Example
• Copy DBLogin.html, DBLoginInitialization.jsp,
Table.jsp, BrowseTable.jsp to liangweb
• Copy DBBean.java to liangweb/WEBINF/classes/chapter35 and compile it to
DBBean.class
• Startup MySQL
• Run http://localhost:8080/liangweb/DBLogin.html
