当我在 ubuntu 12/JDK7（在 VM/虚拟机上运行）上启动 tomcat7.0_26 时，我不断收到有关日志目录中 catalina.out 文件中的 DataSourceFactory 的以下错误。任何想法如何解决？我也复制了下面的相关 server.xml 和 context.xml 部分。我可以使用提供的用户名/密码组合连接到 postgres 数据库。

服务器.xml：

<Resource type="javax.sql.DataSource"
      name="jdbc/DB"
      factory="org.apache.tomcat.jdbc.pool.DataSourceFactory"
      driverClassName="org.postgresql.Driver"
      url="jdbc:postgresql://localhost:5432/DBName"
      username="database-user"
      password="database-user-pwd"
      testWhileIdle="true"
      testOnBorrow="true"
      testOnReturn="false"
      validationQuery="SELECT 1"
      validationInterval="30000"
      timeBetweenEvictionRunsMillis="30000"
      maxActive="100"
      minIdle="10"
      maxWait="10000"
      initialSize="10"
      removeAbandonedTimeout="60"
      removeAbandoned="true"
      logAbandoned="true"
      minEvictableIdleTimeMillis="30000"
      jmxEnabled="true"

上下文.xml

  <ResourceLink type="javax.sql.DataSource"

                global="jdbc/DB"/>

您似乎缺少 jar 文件tomcat-jdbc.jar。默认情况下，它不包含在标准 Debian/Ubuntu 软件包中。您可以从Maven Central下载它。
