Hi. I'm running a restlet 2.0.5 app with SpringServerServlet in web.xml on a jetty 7.2.2 instance, this one http://download.eclipse.org/jetty/7.2.2.v20101205/dist/
This is the error: java.lang.LinkageError: loader constraint violation: when resolving overridden method "org.restlet.ext.spring.SpringServerServlet.createApplication(Lorg/restlet/Context;)Lorg/restlet/Application;" the class loader (instance of org/eclipse/jetty/webapp/WebAppClassLoader) of the current class, org/restlet/ext/spring/SpringServerServlet, and its superclass loader (instance of org/eclipse/jetty/start/Classpath$Loader), have different Class objects for the type org/restlet/Application used in the signature This does not happen at startup but the first time a URL for a restlet resource is called. My war only contains a few lib jars, the most of them are under JETTY/lib/ext. Any tip on how to fix this? Thanks for any help, here follows the jetty installation lib details: here are the jars of /lib the ditribution default -rw-rw-r-- 1 117K 2010-12-06 15:25 servlet-api-2.5.jar -rw-rw-r-- 1 29K
