Servlet and Tomcat Tutorial ECT 7130

Download Tomcat http://ftp.cuhk.edu.hk/pub/packages/apache.org/tomcat/tomcat-5/v5.5.28/bin/apache-tomcat-5.5.28.zip Put under C:\ and unzip to C:\apache-tomcat-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-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\classes

Download www.cs.armstrong.edu/liang/intro6e/supplement/web.xml to c:\apache-tomcat-5.5.28\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-tomcat-5.5.28/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: 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 apache-tomecat\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/WEB-INF/classes/chapter35 and compile it to DBBean.class Startup MySQL Run http://localhost:8080/liangweb/DBLogin.html
