Linux配置Tomcat資料來源（DB2）

驗證Linux配置Tomcat資料來源（DB2）時，資料來源的配置如下：

conf\server.xml：

<GlobalNamingResources>

    <!-- Test entry for demonstration purposes -->
    <Environment name="simpleValue" type="java.lang.Integer" value="30"/>

    <!-- Editable user database that can also be used by
         UserDatabaseRealm to authenticate users -->
    <Resource name="UserDatabase" auth="Container"
              type="org.apache.catalina.UserDatabase"
       description="User database that can be updated and saved"
           factory="org.apache.catalina.users.MemoryUserDatabaseFactory"
          pathname="conf/tomcat-users.xml" />
    <Resource driverClassName="com.ibm.db2.jcc.DB2Driver" maxActive="4" maxIdle="2" maxWait="5000" name="DefaultDataSource" password="123456" type="javax.sql.DataSource" url="jdbc:db2://127.0.0.1:50000/zxdb" username="db2admin"/>
  </GlobalNamingResources>

conf\context.xml：

<Context>

    <!-- Default set of monitored resources -->
    <WatchedResource>WEB-INF/web.xml</WatchedResource>
 
    <!-- Uncomment this to disable session persistence across Tomcat restarts -->
    <!--
    <Manager pathname="" />
    -->
  <ResourceLink global="DefaultDataSource" name="DefaultDataSource" type="javax.sql.DataSource"/>
</Context>

異常錯誤資訊如下：

Message: 沒有找到名稱為 ''{0}'' 的資料來源.(the datasource with

name 'default' cannot get connection!)

com.primeton.common.connection.impl.datasource.ext.UnconfirmedD

ataSource.getDataSource(UnconfirmedDataSource.java:83)

com.primeton.common.connection.impl.datasource.ext.UnconfirmedD

ataSource.getConnection(UnconfirmedDataSource.java:124)

將db2jcc.jar、db2jcc_license_cisuz.jar、db2jcc_license_cu.jar、jta.jar（解決java.lang.NoClassDefFoundError: javax/transaction/UserTransaction）
4個jar包，放到Tomcat的common\lib目錄下，然後重啟服務。
