Dears,

I am very interested to your project sdn_wise. Currently I am using your guide: http://sdn-wise.dieei.unict.it/docs/guides/GetStarted.html. But I am facing a problem to import the new mote type: Sink. In fact, I have got these error messages: [java] Caused by: java.lang.ClassNotFoundException: com.github.sdnwiselab.sdnwise.packet.NetworkPacket [java] at java.net.URLClassLoader.findClass(URLClassLoader.java:381) [java] at java.lang.ClassLoader.loadClass(ClassLoader.java:424) [java] at java.lang.ClassLoader.loadClass(ClassLoader.java:357) [java] ... 46 more [java] FATAL [AWT-EventQueue-0] (GUI.java:2172) - Exception when creating mote type [java] se.sics.cooja.MoteType$MoteTypeCreationException: Error when loading class from: /home/user/contiki/tools/cooja/examples/sdn-wise_java/build com.github.sdnwiselab.sdnwise.cooja.Sink [java] at se.sics.cooja.motes.ImportAppMoteType.createError(ImportAppMoteType.java:164) [java] at se.sics.cooja.motes.ImportAppMoteType.configureAndInit(ImportAppMoteType.java:154) [java] at se.sics.cooja.GUI.doCreateMoteType(GUI.java:2167) [java] at se.sics.cooja.GUI.doCreateMoteType(GUI.java:2146) [java] at se.sics.cooja.GUI$GUIEventHandler.actionPerformed(GUI.java:2928) [java] at javax.swing.AbstractButton.fireActionPerformed(AbstractButton.java:2022) [java] at javax.swing.AbstractButton$Handler.actionPerformed(AbstractButton.java:2348) [java] at javax.swing.DefaultButtonModel.fireActionPerformed(DefaultButtonModel.java:402) [java] at javax.swing.DefaultButtonModel.setPressed(DefaultButtonModel.java:259) [java] at javax.swing.AbstractButton.doClick(AbstractButton.java:376) [java] at javax.swing.plaf.basic.BasicMenuItemUI.doClick(BasicMenuItemUI.java:833) [java] at javax.swing.plaf.basic.BasicMenuItemUI$Handler.mouseReleased(BasicMenuItemUI.java:877) [java] at java.awt.Component.processMouseEvent(Component.java:6533) [java] at javax.swing.JComponent.processMouseEvent(JComponent.java:3324) [java] at java.awt.Component.processEvent(Component.java:6298) [java] at java.awt.Container.processEvent(Container.java:2236) [java] at java.awt.Component.dispatchEventImpl(Component.java:4889) [java] at java.awt.Container.dispatchEventImpl(Container.java:2294) [java] at java.awt.Component.dispatchEvent(Component.java:4711) [java] at java.awt.LightweightDispatcher.retargetMouseEvent(Container.java:4888) [java] at java.awt.LightweightDispatcher.processMouseEvent(Container.java:4525) [java] at java.awt.LightweightDispatcher.dispatchEvent(Container.java:4466) [java] at java.awt.Container.dispatchEventImpl(Container.java:2280) [java] at java.awt.Window.dispatchEventImpl(Window.java:2746) [java] at java.awt.Component.dispatchEvent(Component.java:4711) [java] at java.awt.EventQueue.dispatchEventImpl(EventQueue.java:758) [java] at java.awt.EventQueue.access$500(EventQueue.java:97) [java] at java.awt.EventQueue$3.run(EventQueue.java:709) [java] at java.awt.EventQueue$3.run(EventQueue.java:703) [java] at java.security.AccessController.doPrivileged(Native Method) [java] at java.security.ProtectionDomain$JavaSecurityAccessImpl.doIntersectionPrivilege(ProtectionDomain.java:76) [java] at java.security.ProtectionDomain$JavaSecurityAccessImpl.doIntersectionPrivilege(ProtectionDomain.java:86) [java] at java.awt.EventQueue$4.run(EventQueue.java:731) [java] at java.awt.EventQueue$4.run(EventQueue.java:729) [java] at java.security.AccessController.doPrivileged(Native Method) [java] at java.security.ProtectionDomain$JavaSecurityAccessImpl.doIntersectionPrivilege(ProtectionDomain.java:76) [java] at java.awt.EventQueue.dispatchEvent(EventQueue.java:728) [java] at java.awt.EventDispatchThread.pumpOneEventForFilters(EventDispatchThread.java:201) [java] at java.awt.EventDispatchThread.pumpEventsForFilter(EventDispatchThread.java:116) [java] at java.awt.EventDispatchThread.pumpEventsForHierarchy(EventDispatchThread.java:105) [java] at java.awt.EventDispatchThread.pumpEvents(EventDispatchThread.java:101) [java] at java.awt.EventDispatchThread.pumpEvents(EventDispatchThread.java:93) [java] at java.awt.EventDispatchThread.run(EventDispatchThread.java:82) [java] Caused by: java.lang.NoClassDefFoundError: com/github/sdnwiselab/sdnwise/packet/NetworkPacket [java] at java.lang.Class.getDeclaredConstructors0(Native Method) [java] at java.lang.Class.privateGetDeclaredConstructors(Class.java:2671) [java] at java.lang.Class.getConstructor0(Class.java:3075) [java] at java.lang.Class.getConstructor(Class.java:1825) [java] at se.sics.cooja.motes.ImportAppMoteType.configureAndInit(ImportAppMoteType.java:150) [java] ... 41 more [java] Caused by: java.lang.ClassNotFoundException: com.github.sdnwiselab.sdnwise.packet.NetworkPacket [java] at java.net.URLClassLoader.findClass(URLClassLoader.java:381) [java] at java.lang.ClassLoader.loadClass(ClassLoader.java:424) [java] at java.lang.ClassLoader.loadClass(ClassLoader.java:357)

Have you an idea how to fix it ? I really appriciate your support. Kind regards

I fix this problem by using the last version (3) of Instant Contiki image. Thanks for your good work. Could you please tell us when the integration of ONOS and Cooja can be done ?
