    copied!<p>Perhaps not a Maven issue then. m2e / wtp issue, maybe? </p> <p>Just to give a background, I set up an ICEFaces project in Eclipse and deployed it in Tomcat 7.0.30. It appears the Maven POM configuration for servlet-api.jar to be in provided scope is disregarded while deploying to Tomcat. Am I missing anything? How do I get Maven to do it right?</p> <p>In the project <strong>javax.servlet-api.jar</strong> is pulled in as a transitive dependency of ICEFaces. Since Tomcat comes with it's own servlet-api.jar I marked it to be excluded and added an explicit dependency (scope:provided).</p> <blockquote> <p>INFO: Starting Servlet Engine: Apache Tomcat/7.0.30<br> 06-Mar-2013 10:44:05 org.apache.catalina.loader.WebappClassLoader validateJarFile INFO: validateJarFile(D:\workspaces\test-project\.metadata\.plugins\org.eclipse.wst.server.core\tmp0\wtpwebapps\test-project\WEB-INF\lib\javax.servlet-api-3.0.1.jar) - jar not loaded.
