Jakarta ee WildFly部署失败-“；JBAS014771：缺少/不可用依赖项的服务”；

我不熟悉Web服务。我从另一个开发者那里接管了一些开发项目。 一切都很顺利，直到我创建了自己的测试项目，以查看所有内容如何配合。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，并部署到WildFly服务器

日志显示以下错误消息：

我解决了与你的问题非常相似的问题

错误日志实际上会告诉您在哪里查找，它实际上说您的jdbc驱动程序丢失了。WildFly server deployments文件夹中缺少文件sqljdbc4.jar。您需要将jar文件添加到独立-->部署中。添加丢失的jar文件后，部署对我来说可以正常工作

我逐渐意识到（至少在我的例子中）在我的一次部署尝试中，WildFly服务器上的垃圾收集器出了问题。这将导致在服务器上取消部署所需的jar文件（在您的示例中是sqljdbc4.jar）。由于这是您自己的应用程序的依赖项，因此部署应用程序将无法工作

---

如果在deployments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。您可能可以从WildFly管理控制台执行此操作，但我还不知道具体操作方法。您也可以通过转到deployments文件夹，找到一个名为与丢失的jar文件完全相同但扩展名为.undeployed的文件（在您的示例中是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。

您好，我的项目中也有类似的问题，您有没有找到解决方案？如果您还没有找到解决方案。那个问题的解决使他的问题很快就解决了。我已经尝试过这样做，但遗憾的是，这并没有解决我的问题。无论如何，也许它解决了您的问题…？@Harriet如果standalone.xml元素中的属性配置错误，也会发生此错误。
