i tried use listener:

<listener> <listener-class>com.company.ecm.appsrv.logging.impl.loggingsetup</listener-class> </listener> 

but doesn't seem change anything.

loggingsetup.java:

package com.company.ecm.appsrv.logging.impl;  import java.io.ioexception; import java.io.inputstream; import java.util.properties;  import javax.servlet.servletcontext; import javax.servlet.servletcontextevent; import javax.servlet.servletcontextlistener;  import org.apache.log4j.logger; import org.apache.log4j.propertyconfigurator;  public class loggingsetup implements servletcontextlistener {     @override     public void contextdestroyed(servletcontextevent sce)     {         // nope     }      @override     public void contextinitialized(servletcontextevent sce)     {         servletcontext sctx = sce.getservletcontext();         properties props = new properties();          inputstream ins = null;          try         {             ins = sctx.getresourceasstream("/web-inf/lib/log4j.properties");             if(ins == null)                 throw new runtimeexception("could not find log4j properties");             props.load(ins);             string ctxname = sctx.getcontextpath().substring(1);             props.put("contextname", ctxname);             propertyconfigurator.configure(props);             logger.getrootlogger().info("loggin set up.");         }         catch(ioexception ex)         {             ex.printstacktrace();             sctx.log("could not setup logging", ex);         }                 {             if(ins != null)             {                 try { ins.close(); } catch(ioexception ex) { /* ignored */ }             }         }     } }

set following context param:

  <context-param>     <param-name>log4jconfiglocation</param-name>     <param-value>/web-inf/config/log4j/log4j.properties</param-value>   </context-param> 

don't forget add

 <listener>     <listener-class>org.springframework.web.util.log4jconfiglistener</listener-class>   </listener>
