Subject RE: Flush in RollingRandomAccessFile
Date Thu, 27 Sep 2018 16:20:02 GMT
It seems my web.xml is ok. It's a servlet 3.1 with tomcat 8.5.32. I only have this context
parameter, necessary for a correct log4j startup:

<web-app xmlns="http://xmlns.jcp.org/xml/ns/javaee"
         xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
         xsi:schemaLocation="http://xmlns.jcp.org/xml/ns/javaee http://xmlns.jcp.org/xml/ns/javaee/web-app_3_1.xsd"
         version="3.1"> 
      
  <display-name>ventusproxy</display-name>
  <description>ventusproxy</description>

  <context-param>
        <param-name>isLog4jContextSelectorNamed</param-name>
        <param-value>true</param-value>
  </context-param>
    
  <context-param>
        <param-name>log4jContextName</param-name>
        <param-value>ventusproxy</param-value>
  </context-param>

( ... )

Joan.

That depends on what servlet version you are using. Take a look at http://logging.apache.org/log4j/2.x/manual/webapp.html
<http://logging.apache.org/log4j/2.x/manual/webapp.html>.
