Choose unique values for the ' Webapprootkey ' Context-param in your web. XML files! The wrong solution

The main idea is that Log4jconfiglistener is replaced by the value of the latter context when it gets the Webapp.root value, so configure the different Webapprootkey values in Web. XML for each project, and then add them in one of the Web. xml:

<context-param><param-name>webapprootkey</param-name><param-value>web.sample.root</ Param-value></context-param>

　　

Restart Tomcat for problem resolution.
