Guest Navie Posted November 21, 2011 Report Share Posted November 21, 2011 Does anyone know how to fix this please? I downloaded SDK and then used Eclipse for app development The error is caused by something I use, if that's important I can state what it is but don't feel it is at the moment. Caused by: java.lang.ClassNotFoundException: org.apache.log4j.Logger at sun.plugin2.applet.Applet2ClassLoader.findClass(Unknown Source) at sun.plugin2.applet.Plugin2ClassLoader.loadClass0(Unknown Source) at sun.plugin2.applet.Plugin2ClassLoader.loadClass(Unknown Source) at sun.plugin2.applet.Plugin2ClassLoader.loadClass(Unknown Source) at java.lang.ClassLoader.loadClass(Unknown Source) ... 23 more Exception: java.lang.RuntimeException: java.lang.NoClassDefFoundError: org/apache/log4j/Logger Link to comment Share on other sites More sharing options...
Guest _hifi_ Posted November 22, 2011 Report Share Posted November 22, 2011 Hi Navie, This error means the code you use needs Log4J library - link Anyway I do not think it is a common practice to use it in mobile development, it's created for Java SE/EE Link to comment Share on other sites More sharing options...
