与Cannot load net.sourceforge.jtds.jdbc.Driver in Tomcat相同的错误，但该解决方案此时不起作用。刚刚在FreeBSD 10服务器上完成了Tomcat 8.0.9到8.0.12的更新，并且即使jtds jar在lib文件夹中也会再次出现该错误。我已经下载了一个新的jtds副本，以防旧的损坏，我也重新部署了我的WAR（以防万一）。不用找了。很明显，回滚到Tomcat 8.0.9是一种解决方法，但我有一些时间来处理它，尝试在服务器软件上保持最新状态是明智的......关于为什么我可能会再次出现此错误的想法以及如何解决它？无法在Tomcat中加载net.sourceforge.jtds.jdbc.Driver - 再次

什么是错误信息？例外？堆栈跟踪？你如何加载驱动程序？ – 2014-09-12 11:49:53
错误是“无法加载net.sourceforge.jtds.jdbc.Driver”我将在完整的堆栈跟踪中进行编辑。 – 2014-09-12 15:23:43
我很难在我们的存储库中找到代码（这是一个我几年没有修改的旧程序，并且在过去几年中，我们的存储库中的项目数量已经绝对爆炸）。当我找到它时，我会继续搜索并发布它。 – 2014-09-12 15:30:05
