I'm stepping through the example Professional Apache Tomcat 5 book by Wrox in
Chapter 14 - I have set up the mysql database and confirmed it works and set up
the tomcat server and confirmed that I can see my index.jsp page. When I try to
go to http://localhost:8070/jsp-examples/wroxjdbc/JDBCTest.jsp
I get a standard The page cannot be displayed page.
I've included all my steps below. Anyone that can help is most appreciated.
Thanks in advance.....Dave
Steps I have done
1) Created a DB called everycitizen and a table called test with a column
called pk. Created user everyuser w/ a password and granted Select privileges
to that user.
2) Copied the mysql-connector-java-3.1.12-bin.jar into
$CATALINA_HOME/common/lib.
3)Added the following to the $CATALINA_HOME/conf/server.xml just before the
</Host tag>. Password is blotted out.
<!-- added by DM 2/22/2006 -->
<DefaultContext>
<Resource name="jdbc/WroxTC5" auth="Container" type="javax.sql.Datasource"
driverClassName="com.mysql.jdbc.Driver"
url="jdbc:mysql://localhost/everycitizen"
username="everyuser" password="everypass" maxActive="20" maxIdle="30000"
maxWait="100"/>
</DefaultContext>
4) Added the following to the $CATALINA_HOME/webapps/jsp-examples/WEB-INF
web.xml file at the bottom just before the </web-app> entry after the last
env-entry.
<resource-ref>
<res-ref-name>jdbc/WroxTC5</res-ref-name>
<res-type>javax.sql.DataSource</res-type>
<res-auth>Container</res-auth>
</resource-ref>
5) Added the JDBCTest.jsp file and the errorpg.jsp file to
$CATALINA_HOME/webapps/jsp-examples/wroxjdbc directory. I created the wroxjdbc
folder. The JDBC Test is:
<html>
<head>
<%@ page errorPage="errorpg.jsp"
import="java.sql.*,
javax.sql.*,
java.io.*,
javax.naming.InitialContext,
javax.naming.Context" %>
</head>
<h1>JDBC JNDI Resource Test</h1>
<%
InitialContext initCtx = new InitialContext();
DataSource ds = (DataSource)initCtx.lookup("java:comp/env/jdbc/WroxTC5");
Connection conn = ds.getConnection();
Statement stmt = conn.createStatement();
ResultSet rset = stmt.executeQuery("select * from test;");
%>
<table width = '600' border='1'>
<tr>
<th align='left'>XXXX</th>
</tr>
<%
while (rset.next())
{
%>
<tr><td> <%=rset.getInt(0)%></td></tr>
<% }
rset.close();
stmt.close();
conn.close();
initCtx.close();
%>
</table>
</html>
and the errorpg is:
<html>
<%@ page isErrorPage="true" %>
<h1> An error has occurred </h1>
<%= exception.getMessage() %>
</html>
