I was facing the same issue. Then I noticed that I have accidentally deleted lib folder from tomcat directory. The issue got resolved as lib folder back in place.
我面临着同样的问题。然后我注意到我不小心从 tomcat 目录中删除了 lib 文件夹。问题得到解决，因为 lib 文件夹回到原位。

From my experience, I have observed that tomcatsometimes throws this when there are project dependent jars (could be transitively dependent as well) missing, or not being pointed to properly, or corrupted. So, please check the health of the jars deployed in the server and their dependencies. For example, if you are using mavento build your project jars, you could once clear the .m2/repositoryand rebuild the project and deploy again.
根据我的经验，我观察到tomcat有时会在项目依赖 jar（也可能是传递依赖）丢失、未正确指向或损坏时抛出此问题。因此，请检查部署在服务器中的 jars 及其依赖项的健康状况。例如，如果您正在使用maven构建您的项目 jar，您可以一次清除.m2/repository并重建项目并再次部署。

The problem was resolved by adding ejb.jar file into Tomcat/lib folder which is the dependency package to startup.
通过将ejb.jar文件添加到Tomcat/lib文件夹中解决了该问题，该文件夹是要启动的依赖包。

Sometimes, even though all the necessary things are perfect, this error would be reported if there is user VM arguments enclosed with the double quotes, I spent a day to get rid of this. check in run --> run configuration, in arguments tab, VM Arguments, check for the user entries is enclosed with quotes/spaces, if so remove it and 'Run'
有时，即使所有必要的东西都很完美，但如果有用户 VM 参数用双引号括起来，就会报告此错误，我花了一天的时间来摆脱这个错误。签入运行 --> 运行配置，在参数选项卡，VM 参数中，检查用户条目是否用引号/空格括起来，如果是，请将其删除并“运行”

In my case I changed catatina.properties file found in tomcat_directory/conf from
在我的情况下，我将在 tomcat_directory/conf 中找到的 catatina.properties 文件从
common.loader='${catalina.base}/lib','${catalina.base}/lib/*.jar','${catalina.home}/lib','${catalina.home}/lib/*.jar'
To
到
common.loader=${catalina.base}/lib,${catalina.base}/lib/*.jar,${catalina.home}/lib,${catalina.home}/lib/*.jar
However the file always used to get overwritten. I was using eclipse. So, I did the same change in the Servers Project in eclipse. In my case it was Servers/Tomact v9.0 Server/catalina.properties. I did the same change stated above in this file too. It worked for me.
然而，该文件总是被覆盖。我正在使用日食。所以，我在 eclipse 中的 Servers Project 中做了同样的改变。就我而言，它是 Servers/Tomact v9.0 Server/catalina.properties。我也在这个文件中做了同样的改变。它对我有用。
