sep 30, 2011 2:34:09 AM org.apache.catalina.loader.WebappClassLoader clearThreadLocalMap
Grave: A web application created a ThreadLocal with key of type [null] (value [com.opensymphony.xwork2.inject.ContainerImpl$10@95 98c0]) and a value of type [java.lang.Object[]] (value [[Ljava.lang.Object;@15f73e9]) but failed to remove it when the web application was stopped. To prevent a memory leak, the ThreadLocal has been forcibly removed.


He probado Tomcat con una servlet y funciona, he copiado todos lo JARs de lib struts2 en WEB-INF>lib, he verificado que en java build path existen.
Gracias por adelantado
