我是Web服务的新手。我从另一个开发人员那里接手了一些开发项目。一切都很顺利，直到我创建了自己的测试项目，看看一切是如何结合在一起的。当我从测试项目恢复到以前的工作项目时，项目会编译，但在部署期间不会启动。我甚至不知道从哪里开始寻找。
我正在使用EclipseKepler，并将其部署到WildFly服务器上。
日志显示以下错误消息：

我解决了与您的问题非常相似的问题。
错误日志实际上告诉了您应该在哪里查找，它实际上表明您的jdbc驱动程序丢失了。WildFly服务器部署文件夹中缺少文件sqljdbc4.jar。您需要将jar文件添加到<your_wildfly_server_folder> --> standalone --> deployments中。在添加了丢失的jar文件后，部署对我来说还可以
我已经意识到（至少在我的情况下）在我的一次部署尝试中，WildFly服务器上的垃圾收集器出现了问题。这将导致在服务器上取消部署所需的jar文件（在您的案例中为sqljdbc4.jar）。由于这是您自己的应用程序的依赖项，因此部署您的应用程序将不起作用。
如果您在deployment文件夹中看到jar文件，但仍然无法部署应用程序，则需要首先重新部署jar文件。你可能可以在WildFly管理控制台上完成这项操作，但我还没有找到确切的方法。您也可以转到deployed文件夹，找到一个与您丢失的jar文件完全相同但扩展名为.undeployed的文件（在您的情况下为sqljdbc4.jar.undeployed），然后将其删除。如果一切顺利，WildFly将自动重新部署您的jar文件。
