引起：java.lang.ClassNotFoundException：oracle.jdbc.OracleDriver [英] Caused by: java.lang.ClassNotFoundException: oracle.jdbc.OracleDriver

问题描述

我在lib文件夹中创建了一个带有ojdbc14.jar的Web应用程序。

I created a web application with ojdbc14.jar in lib folder.

然而，当我启动tomcat时出现错误：

However, when I start my tomcat I get an error:

Caused by: java.lang.ClassNotFoundException: oracle.jdbc.OracleDriver

虽然它存在！

当我在Eclipse中将同一个应用程序部署到我的本地tomcat时，它工作正常。

When I deploy the same application to my local tomcat in Eclipse it works fine.

然而，当我从Eclipse部署它时，我得到了这条消息，虽然jar存在！

However when I deploy it out of Eclipse I get this message, although the jar exists!

EDITED

我也从META-INF文件夹下的context.xml中引用它：

I refer to it also from the context.xml under META-INF folder:

<WatchedResource>WEB-INF/web.xml</WatchedResource>
     <Transaction factory="bitronix.tm.BitronixUserTransactionObjectFactory" />
     <Resource name="jdbc/testDS1" auth="Container" type="javax.sql.DataSource"
               maxActive="15" maxIdle="2" maxWait="10000"
               logAbandoned="true"
               username="cust" password="cust"
               driverClassName="oracle.jdbc.OracleDriver"
               url="jdbc:oracle:thin:@myserver:id:name"/>

推荐答案

您确定它存在于webapps / yourapp / WEB中吗？ -INF / lib文件夹？如果在特定目录中无法看到它，则必然会抛出异常。

Are you sure it exists inside webapps/yourapp/WEB-INF/lib folder? It is bound to throw that exception if it can't be seen in that specific directory.

如何部署eclipse？您是否导出WAR文件并进行部署？验证您的WAR文件是否包含指定位置的ojdbc14.jar。

How do you deploy out of eclipse? Do you export a WAR file and deploy? Verify that your WAR file contains ojdbc14.jar in the specified location.
