6. 修改web.XML的内容
web.xml:
＜?xml version="1.0" encoding="UTF-8"?＞
＜web-app
xmlns="http://java.sun.com/xml/ns/J2EE"
xmlns:xsi=
"http://www.w3.org/2001/XMLSchema-instance"
xsi:schemaLocation=
"http://java.sun.com/xml/ns/j2ee
http://java.sun.com/xml/ns/j2ee/web-app_2_4.xsd"
version="2.4"＞
＜description＞MySQL Test App＜/description＞
＜resource-ref＞
＜description＞DB Connection＜/description＞
＜res-ref-name＞jdbc/TestDB＜/res-ref-name＞
＜res-type＞javax.sql.DataSource＜/res-type＞
＜res-auth＞Container＜/res-auth＞
＜/resource-ref＞
＜/web-app＞ |
7. F9运行应用，myWeb目录中将会生成Tomcat子目录，其中包含了conf子目录，在Tomcat_HOME\conf\Catalina\localhost目录中生成了DBTest.XML文件。
8. 将myWeb\Tomcat\conf目录中的文件server8080.xml加入工程文件，修改server8080.xml的内容：
server8080.xml:
＜?xml version="1.0"
encoding="UTF-8"?＞
＜Server debug="0" port="8081"
shutdown="SHUTDOWN"＞
＜Service name="Catalina"＞
＜Connector acceptCount="10"
connectionTimeout="60000" debug="0"
maxThreads="75" minSpareThreads="5"
port="8080"/＞
＜Engine debug="0"
defaultHost="localhost"
name="Catalina"＞
＜Host apPBase=
"C:\myWeb\Tomcat\webapps"
autoDeploy="false" debug="0"
deployXML="false" name="localhost"
unpackWARs="false"＞
＜Context path="/DBTest"
docBase="C:\myWeb\DBTest"
debug="5" reloadable="true"
crossContext="true"
workDir="C:\myWeb\Tomcat\work\DBTest"＞
＜Logger
className="org.apache.catalina.logger.FileLogger" prefix="localhost_DBTest_log."
suffix=".txt" timestamp="true"/＞
＜Resource name="JDBC/TestDB"
auth="Container"
type="Javax.sql.DataSource"/＞
＜ResourceParams name="jdbc/TestDB"＞
＜parameter＞
＜name＞factory＜/name＞
＜value＞org.apache.commons.dbcp.
BasicDataSourceFactory＜/value＞
＜/parameter＞
＜!--
Maximum number of dB
connections in pool. Make sure you
configure your MySQLd
max_connections large enough to handle
all of your db
connections. Set to 0 for no limit.
--＞
＜parameter＞
＜name＞maxActive＜/name＞
＜value＞100＜/value＞
＜/parameter＞
＜!--
Maximum number of idle dB
connections to retain in pool.
Set to 0 for no limit.
--＞
＜parameter＞
＜name＞maxIdle＜/name＞
＜value＞30＜/value＞
＜/parameter＞
＜!--
Maximum time to wait for a dB
connection to become available
in ms, in this example 10 seconds.
An Exception is thrown if
this timeout is exceeded.
Set to -1 to wait indefinitely.
--＞
＜parameter＞
＜name＞maxWait＜/name＞
＜value＞10000＜/value＞
＜/parameter＞
＜!-- MySQL dB username and
password for dB connections --＞
＜parameter＞
＜name＞username＜/name＞
＜value＞sa＜/value＞
＜/parameter＞
＜parameter＞
＜name＞password＜/name＞
＜value＞topcomputer＜/value＞
＜/parameter＞
＜!-- Class name for mm.mysql JDBC driver --＞
＜parameter＞
＜name＞driverClassName＜/name＞
＜value＞com.microsoft.
jdbc.sqlserver.SQLServerDriver＜/value＞
＜/parameter＞
＜!--
The JDBC connection url
for connecting to your MySQL dB.
The autoReconnect=true argument
to the url makes sure that the
mm.mysql JDBC Driver will
automatically reconnect if mysqld closed the
connection. mysqld by default
closes idle connections after 8 hours.

＜parameter＞
＜name＞url＜/name＞
＜value＞jdbc:microsoft:sqlserver:
//nt04:1433;DatabaseName=test＜/value＞
＜/parameter＞
＜/ResourceParams＞
＜/Context＞
＜/Host＞
＜/Engine＞
＜/Service＞
＜/Server＞ |
