We are trying to migrate our Struts application from WebSphere 3.5.4 to WebSphere 4.0 on an AIX box and we are running into trouble. We then decided to migrate the Struts example to 4.0. When we move the working war file for the Struts example to 4.0 we get the following error when we try to edit the registration - Error 500: org.apache.struts.util.BeanUtils: method filter(Ljava/lang/String;)Ljava/lang/String; not found Any ideas? Thanks, Jim Young Amicus
