Am using Weblogic 12.2.1.4 and on deploying my ear file am getting the following error. My ear is done with JSF 2.2. Answer Method “addSearchKeywordResolver” is part of JSF 2.3 specification. https://javaee.github.io/javaee-spec/javadocs/javax/faces/component/search/SearchKeywordResolver.html Therefore, if you want to use it, you will have to include the dependencies for JSF 2.3 in your ear file.
