java.lang.ClassNotFoundException：org.apache.tomcat.jdbc.pool DataSourceFactory

java.lang.ClassNotFoundException：org.apache.tomcat.jdbc.pool DataSourceFactory

我正在研究如何脱离Oracle连接池并使用Tomcat连接池。我遵循了无数的示例来<Resource>在Tomcat的中进行配置/conf/server.xml。我在这里找到了很好的信息。但是，当我启动Tomcat时，出现以下错误：

javax.naming.NamingException：无法加载资源工厂类[Root异常是java.lang.ClassNotFoundException：org.apache.tomcat.jdbc.pool
DataSourceFactory]

我正在使用Tomcat 6.0。我的<Resource>配置/conf/server.xml是：

<Resource     name="jdbc/myds"    type="javax.sql.DataSource"    auth="Container"     factory="org.apache.tomcat.jdbc.pool.DataSourceFactory"    driverClassName="oracle.jdbc.OracleDriver"    url="jdbc:oracle:thin:@10.10.10.33:1234:myds"    user="myuname"    password="mypasswd"/>

我知道Tomcat无法找到工厂类，但是我不明白 为什么
？我在文档中看不到有关添加其他.jar文件的任何内容。我查看了发行版，仍然找不到黄金.jar。

谁能告诉我我在做什么错？

答案1

小编典典

Tomcat JDBC池是在Tomcat 7.0.19 中引入的，但是您尝试在没有任何进一步配置的情况下在Tomcat 6.0中使用它。

对于Tomcat 6.0，您需要手动下载最新版本的tomcat-jdbc.jar文件并将其拖放/lib到Tomcat安装文件夹中。

AppEngine ClassNotFoundException：com.google.appengine.api.datastore.DatastoreServiceFactory

AppEngine ClassNotFoundException：com.google.appengine.api.datastore.DatastoreServiceFactory

当我尝试在AppEngine中使用低级DataStore
API时，我得到了一个有趣的东西ClassNotFoundException。此异常发生在云服务器中，而不是在本地实例中。我在本地使用appengine- java-sdk-1.7.4。

ClassNotFoundException: org.apache.tomcat.dbcp.dbcp2.BasicDataSourceFactory

ClassNotFoundException: org.apache.tomcat.dbcp.dbcp2.BasicDataSourceFactory

tomcat 8.5 或是9.0，这些版本的tomcat内置的DBCP2

tomcat 7的用的是DBCP

以上错误可能是版本问题

换成相对应的tomcat版本即可解决

ClassNotFoundException：javax.validation.ValidatorFactory

我正在尝试通过Tomcat在本地计算机上运行Spring MVC应用程序，但是我看到：

NoClassDefFoundError: javax/validation/ValidatorFactory

我validation-api-1.0.0.GA.jar在webapp的lib文件夹中。我正在使用Tomcat7。任何指导将不胜感激。

ClassNotFoundException：net.sourceforge.jtds.jdbc.Driver

ClassNotFoundException：net.sourceforge.jtds.jdbc.Driver

我有连接到MS-SQL数据库并获取一些数据的Java代码。

在运行代码之前，我在Unix Server中设置了类路径，它过去可以正常工作。

但是由于某种原因，几天前 仍在 工作的同一个jar文件抛出了一个Class not found异常
java.lang.ClassNotFoundException：net.sourceforge.jtds.jdbc.Driver

我解压缩了jar文件，发现正在加载的驱动程序类：

Class.forName("net.sourceforge.jtds.jdbc.Driver");

存在于指定的包装结构中。

我不知道这是怎么回事。

任何人都可以提出解决此问题的任何提示。
