我已經在stackoverflow上看到了幾個類似的問題，但它們沒有解決我的問題。 This one是特別有用的，因爲它指向官方tomcat documentation，特別是this section。tomcat7：無法加載JDBC驅動程序類[com.mysql.jdbc.Driver]
提供的解決方案簡而言之就是：tomcat需要將jdbc數據庫驅動程序複製到$CATALINA_HOME/lib，因爲它不會在WEB-INF/lib/下找到它們。好吧，但它仍然不適合我，而我正在變得生氣。
讓我們看看您是否可以提供任何進一步的想法。
環境是Windows XP，Tomcat7，Eclipse Indigo，Java6和Spring3。
mysql-connector已被複制到$CATALINA_HOME/lib
C:\>dir "c:\Program Files\Apache-Tomcat-7.0.12\lib"\mysql*
[...]
/2012 13:39 877.094 mysql-connector-java-5.1.21.jar
[...]
C:\>
你可能知道，Eclipse的Tomcat集成創造了其部署（CATALINA_BASE）特定WTP的目錄，所以我複製的MySQL連接器也有（我已經失敗試圖在CATALINA_HOME的mysql-conector.jar，在CATALINA_BASE和他們兩個）：
C:\>dir c:\Share\genesis\wsEclipse-indigo\.metadata\.plugins\org.eclipse.wst.server.core\tmp0\lib
[...]
29/08/2012 13:39 877.094 mysql-connector-java-5.1.21.jar
[...]
C:\>
據我瞭解Tomcat的CA talina.properties文件，它們都被添加到類路徑中，所以我沒有期待任何區別，但我試過了，以防萬一。
我的春天數據源定義很簡單：
<bean id="securityDataSource"
class="org.springframework.jdbc.datasource.DriverManagerDataSource">
<property name="driverClassName" value="com.mysql.jdbc.Driver" />
<property name="url" value="jdbc:mysql://localhost:3306/venus" />
<property name="username" value="root" />
<property name="password" value="" />
</bean>
但是，當我重新啓動Tomcat我得到以下錯誤：
ERROR: org.springframework.web.context.ContextLoader - Context initialization failed

還有一個提示：使用Sysinternals的進程資源管理器，我可以看到的是， mysql-connector-java.jar正在由Tomcat公開：
"C:\Program Files\Java\jre6\bin\javaw.exe" -Dcatalina.base=C:\Share\genesis\wsEclipse-indigo\.metadata\.plugins\org.eclipse.wst.server.core\tmp0 "-Dcatalina.home=C:\Program Files\Apache-Tomcat-7.0.12" -Dwtp.deploy=C:\Share\genesis\wsEclipse-indigo\.metadata\.plugins\org.eclipse.wst.server.core\tmp0\wtpwebapps "-Djava.endorsed.dirs=C:\Program Files\Apache-Tomcat-7.0.12\endorsed" -Dfile.encoding=Cp1252 -classpath "C:\Program Files\Apache-Tomcat-7.0.12\bin\bootstrap.jar;C:\Program Files\Apache-Tomcat-7.0.12\bin\tomcat-juli.jar" org.apache.catalina.startup.Bootstrap start
任何進一步的想法？
EDIT1：我試圖使用Oracle和它的作品！
C:\>dir "c:\Program Files\Apache-Tomcat-7.0.12\lib"\oci*

02/10/2006 22:36 1.545.954 ocijdbc10.jar

數據源：

<property name="username" value="me" />
<property name="password" value="qwerty" />
</bean>
我在做什麼錯爲MySQL？
你從一個簡單的Java applicatoin內試圖裝載儀相同的驅動程序 –
這個想法是要找到問題的關鍵看下面的答案 –
