Tomcat的DB2的JDBC數據源配置

Question

我想要配置Tomcat中的DB2數據庫的數據源（使用Eclipse作爲IDE），但我不能解決問題，Tomcat的特羅我以下異常：

這裏我把DB2的JDBC文件？我嘗試在每個地方（在項目的庫中，在tomcat安裝目錄的lib文件夾中，在Dinamic Web Project的WEB-INF/lib文件夾中，在eclipse「tomcat server」配置中的tomcat classpath中到目前爲止）

問候

PS：我使用的是：

DB2 9.7 的Tomcat 6 JDK 1.6 Eclipse的伽利略

你需要把它的Eclipse外面的/lib文件夾Tomcat或任何路徑的特殊字符在/conf/catalina.properties cified在shared.loader或common.loader性質。如果它不能解決問題，那麼它不是您認爲Eclipse正在使用的正確的Tomcat實例。

如果一切順利（丟棄在服務器庫中的JDBC驅動程序），那麼你應該看到它在[項目]/Java的資源（SRC）/庫/ [服務器]在Project Explorer上市露面。
