Description

The web lookup - ${web:rootDir} seems to cause problems on weblogic 12c deployment.

I suspect that the web-lookup plugin is not initialized when weblogic requests the logger at the start of deployment and is unable to create the file.

What I've done - 

1. Added slf4j in weblogic preferred packages of weblogic.xml.

    <wls:package-name>org.slf4j.*</wls:package-name>

2. log4j-web dependency is present in classpath.

3.web.xml contains following:- 

<context-param>
    <param-name>isLog4jAutoInitializationDisabled</param-name>
    <param-value>true</param-value>
</context-param>

<listener>
    <listener-class>org.apache.logging.log4j.web.Log4jServletContextListener</listener-class>
</listener>

<filter>
    <filter-name>log4jServletFilter</filter-name>
    <filter-class>org.apache.logging.log4j.web.Log4jServletFilter</filter-class>
</filter>

<filter-mapping>
    <filter-name>log4jServletFilter</filter-name>
    <url-pattern>/*</url-pattern>
    <dispatcher>REQUEST</dispatcher>
    <dispatcher>FORWARD</dispatcher>
    <dispatcher>INCLUDE</dispatcher>
    <dispatcher>ERROR</dispatcher>
</filter-mapping>

*Note - Log4jServletContextListener is placed before all listeners.

-Have attached stacktrace for your reference.
