注意
l 以下文档都是以mydomain为例
l 本系列文档都是使用相同的配置，即使用以前文档的配置，
1. 将附件中的classes12.zip拷贝到wlserver6.0\lib目录下
2. 修改config\mydomain\startweblogic.cmd文件，在set classpath=。。。一行的最后加入如下语句
;.\lib\classes12.zip
3. 修改mydomain\config.xml文件,在最后加入如下语句
<jdbcconnectionpool
capacityincrement="1"
drivername="oracle.jdbc.driver.oracledriver"
initialcapacity="2"
maxcapacity="4"
name="oraclethinpool"
properties="user=zjcenter;password=zjcenter;dll=ocijdbc8;protocol=thin"
targets="myserver"
url="jdbc:oracle:thin:@172.16.91.36:1521:orcl"//此处根据你的服务器地址做调整//
/>
<jdbctxdatasource
jndiname="webapp.oraclethintxds"
name="otxds"
poolname="oraclethinpool"
targets="myserver"
/>
4. 将附件中的sss.class拷贝到mydomain\applications\webapp\web-inf\classes目录下
5. 修改mydomain\applications\webapp\web-inf\web.xml文件,在
<web-app>
。。。。。。
。。。。。。
</web-app>
之间加入如下语句
<servlet>
<servlet-name>datasourcetest</servlet-name>
<servlet-class>sss</servlet-class>
</servlet>
<servlet-mapping>
<servlet-name>datasourcetest</servlet-name>
<url-pattern>/dst/*</url-pattern>
</servlet-mapping>
6. 启动weblogic default server
7. 访问我们的例子http://127.0.0.1:7001/webapp/dst
8. 测试成功!
9. 例子sss.java
// source file name: sss.java

printwriter.println("<br><hr>");
}
}
catch(exception exception)
{
printwriter.println("connection error:" + exception);
}
finally
{
try
{
if(connection != null)
connection.close();
printwriter.println("********************************");
printwriter.println("\n");
printwriter.println("stmt is");
printwriter.println(statement);
printwriter.println("\n");
printwriter.println("conn is");
printwriter.println(connection);
printwriter.println("********************************");
if(statement != null)
statement.close();
}
catch(sqlexception sqlexception1)
{
printwriter.println("exception during close()" + sqlexception1.getmessage());
}
}
printwriter.println("</b><h3>example finished...</h3></body></html>");
