java.lang.IllegalStateException：启动孩子时出错

Question

I am using tomcat 9 with a maven web application and when I attempt to deploy the war file in the tomcat server I get this error message:

SEVERE [main] org.apache.catalina.startup.HostConfig.deployDescriptor Error deploying deployment descriptor [/Users/me/Desktop/apache-tomcat-9.0.65/conf/Catalina/localhost/admin.xml]

What I have tried:

• Re-installing tomcat
• Checking for duplicate jar files in the web application
• Moving the war file into `home/user/tomcat/webapps as stated in this simular thread
• double checking the web.xml file
• checking the admin.xml file

Answer 2

I had a similar problem. I downgraded to latest Tomcat 8 and my app worked perfectly.
