Hi, within my project, I use the library commons-digester-1.8
Following a need, I now use the library gwt-dev-2.3.0 When launching the application I get this error : Exception caught while initializing context java.lang.NoSuchMethodError: org/apache/commons/digester/xmlrules/DigesterLoader.createDigester(Lorg/xml/sax/InputSource;)Lorg/apache/commons/digester/Digester; at fr.cnasea.commons.webfwk.util.config.lecture.XMLDigesterReader.getConfig(XMLDigesterReader.java:157) at fr.cnasea.commons.webfwk.util.config.CnaseaAppConfigurator.configure(CnaseaAppConfigurator.java:76) at fr.cnasea.osiris.commons.gwt.server.Config.contextInitialized(Config.java:47) It turns out that the two libraries have the same class in the same package with the same method : [image: img.png] <about:invalid#zClosurez> Package : org.apache.commons.digester.xmlrules Class : DigesterLoader Method : createDigester Since the use of gwt-dev, it is the method of this library which is called. I tried to use newer versions of gwt-dev but the environment makes it not possible How can I fix it?
