注意
l 以下文檔都是以mydomain為例
l 本系列文檔都是使用相同的配置，即使用以前文檔的配置，
1. 將附件中的classes12.zip拷貝到wlserver6.0\lib目錄下
2. 修改config\mydomain\startWebLogic.cmd文件，在set CLASSPATH=。。。一行的最后加入如下語句
;.\lib\classes12.zip
3. 修改mydomain\config.xml文件,在最后加入如下語句
<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"//此處根據你的服務器地址做調整//
/>
<JDBCTxDataSource
JNDIName="WebApp.OracleThintxds"
Name="otxds"
PoolName="OracleThinPool"
Targets="myserver"
/>
4. 將附件中的sss.class拷貝到mydomain\applications\WebApp\WEB-INF\classes目錄下
5. 修改mydomain\applications\WebApp\WEB-INF\web.xml文件,在
<web-app>
。。。。。。
。。。。。。
</web-app>
之間加入如下語句
<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. 啟動Weblogic Default Server
7. 訪問我們的例子http://127.0.0.1:7001/WebApp/dst
8. 測試成功!
9. 例子sss.java
