Hello all, I just downloaded apache-marmotta-3.1.0-incubating-webapp.zip from the website and deployed it on a Tomcat 6.0 instance.
I am getting the following error: SEVERE: Error deploying web application archive marmotta.war java.lang.UnsupportedClassVersionError: org/apache/marmotta/platform/core/jndi/MarmottaJndiListener : Unsupported major.minor version 51.0 (unable to load class org.apache.marmotta.platform.core.jndi.MarmottaJndiListener) at org.apache.catalina.loader.WebappClassLoader.findClassInternal(WebappClassLoader.java:2822) at org.apache.catalina.loader.WebappClassLoader.findClass(WebappClassLoader.java:1159) at org.apache.catalina.loader.WebappClassLoader.loadClass(WebappClassLoader.java:1647) at org.apache.catalina.loader.WebappClassLoader.loadClass(WebappClassLoader.java:1526) at org.apache.catalina.startup.WebAnnotationSet.loadClassAnnotation(WebAnnotationSet.java:145) at org.apache.catalina.startup.WebAnnotationSet.loadApplicationListenerAnnotations(WebAnnotationSet.java:73) at org.apache.catalina.startup.WebAnnotationSet.loadApplicationAnnotations(WebAnnotationSet.java:56) at org.apache.catalina.startup.ContextConfig.applicationAnnotationsConfig(ContextConfig.java:297) at org.apache.catalina.startup.ContextConfig.start(ContextConfig.java:1078) at org.apache.catalina.startup.ContextConfig.lifecycleEvent(ContextConfig.java:261) at org.apache.catalina.util.LifecycleSupport.fireLifecycleEvent(LifecycleSupport.java:142) at org.apache.catalina.core.StandardContext.start(StandardContext.java:4612) at org.apache.catalina.core.ContainerBase.addChildInternal(ContainerBase.java:799) at org.apache.catalina.core.ContainerBase.addChild(ContainerBase.java:779) at org.apache.catalina.core.StandardHost.addChild(StandardHost.java:601) at org.apache.catalina.startup.HostConfig.deployWAR(HostConfig.java:943) at org.apache.catalina.startup.HostConfig.deployWARs(HostConfig.java:778) at org.apache.catalina.startup.HostConfig.deployApps(HostConfig.java:504) at org.apache.catalina.startup.HostConfig.start(HostConfig.java:1317) at org.apache.catalina.startup.HostConfig.lifecycleEvent(HostConfig.java:324) at org.apache.catalina.util.LifecycleSupport.fireLifecycleEvent(LifecycleSupport.java:142) at org.apache.catalina.core.ContainerBase.start(ContainerBase.java:1065) at org.apache.catalina.core.StandardHost.start(StandardHost.java:840) at org.apache.catalina.core.ContainerBase.start(ContainerBase.java:1057) at org.apache.catalina.core.StandardEngine.start(StandardEngine.java:463) at org.apache.catalina.core.StandardService.start(StandardService.java:525) at org.apache.catalina.core.StandardServer.start(StandardServer.java:754) at org.apache.catalina.startup.Catalina.start(Catalina.java:595) at sun.reflect.NativeMethodAccessorImpl.invoke0(Native Method) at sun.reflect.NativeMethodAccessorImpl.invoke(NativeMethodAccessorImpl.java:57) at sun.reflect.DelegatingMethodAccessorImpl.invoke(DelegatingMethodAccessorImpl.java:43) at java.lang.reflect.Method.invoke(Method.java:616) at org.apache.catalina.startup.Bootstrap.start(Bootstrap.java:289) at org.apache.catalina.startup.Bootstrap.main(Bootstrap.java:414) Which Java version have you used to build it?
