Here are the versions I installed:<br/> OpenDaylight release downloaded on a virtual machine (Fedora20, 64 bits, using VirtualBox)<br/> LINC last version downloaded on a virtual machine (Ubuntu 13.10, 64 bits, using VirtualBox)</p> <p>I have installed LINC switch and OpenDaylight controller but whenever I try to connect them together, the OpenDaylight controller throws Null Pointer Java Exceptions. This happens whatever OpenDaylight edition I use (Base, Virtualization or ServiceProvider). Through the Web Interface, I see that the controller is connected to the switch but there are errors (Null Pointer Java Exception) in the controller’s log, which make it impossible to push any rule in the switch…</p> <p>However, I have used LINC controller with the default Mininet controller and it works perfectly. <br/> I have also used OpenDaylight controller with OpenvSwitch and it works perfectly too. </p> <p>You will find enclosed the exceptions stacktraces (file opendaylight.log) produced when I tried to connect the switch to the controller. </p> <p>Thanks,</p> <p>Pauline</p> <p>Operating System: Linux<br/> Platform: PC</p> OPNFLWPLUG-79

LINC switch crashes OpenDaylight controller

The fix has been merged and you can either build OFPlugin or just download and run the latest distribution-base zip: <a href="http://nexus.opendaylight.org/content/repositories/opendaylight.snapshot/org/opendaylight/openflowplugin/distributions-openflowplugin-base/0.0.3-SNAPSHOT/" class="external-link" target="_blank" rel="nofollow noopener">http://nexus.opendaylight.org/content/repositories/opendaylight.snapshot/org/opendaylight/openflowplugin/distributions-openflowplugin-base/0.0.3-SNAPSHOT/</a></p> <p>Attachment opendaylight_20140317.log has been added with description: OpenDaylight log file when LINC switch tries to connect</p> <p>Hi,</p> <p>I have downloaded the March 11th zip version (<a href="http://nexus.opendaylight.org/content/repositories/opendaylight.snapshot/org/opendaylight/openflowplugin/distributions-openflowplugin-base/0.0.3-SNAPSHOT/distributions-openflowplugin-base-0.0.3-20140311.155110-18-osgipackage.zip" class="external-link" target="_blank" rel="nofollow noopener">http://nexus.opendaylight.org/content/repositories/opendaylight.snapshot/org/opendaylight/openflowplugin/distributions-openflowplugin-base/0.0.3-SNAPSHOT/distributions-openflowplugin-base-0.0.3-20140311.155110-18-osgipackage.zip</a>) but I get Null Pointer Java Exceptions as soon I connect the LINC switch, eventhough I can see the switch on the web interface...</p> <p>Configuration: Linux Debian 7.<br/> You'll find enclosed the opendaylight.log attached (name: opendaylight_20140317.log).</p> <p>Sorry for the delay and thanks for your help,</p> <p>Pauline</p> <p>Hi Pauline,<br/> this seems to be another bug affecting error message processing. Could you inspect communication through wireshark. This looks like there is a flow request sent to device and device responds with error message. Are you seeing any error responses from switch on the wire?</p> <p>Thank you.</p> <p>Could you try to remove org.opendaylight.openflowplugin.test-provider-0.0.3-SNAPSHOT.jar from your plugins folder? Then the buggy testing implementation of SalFlowListener wont be active.</p> <p>By the way - how are you creating flows. Looks like you are not using config context of dataStore.</p> <p>Thank you.</p> <p>Hi,<br/> I removed the jar file and now everything seems to work, thank you!</p> <p>To answer your question, I am creating flow entries through the web interface, then I just run "pingall" command in Mininet to make sure the flow entries are properly installed. But I am not using config context of dataStore at all. Is this a problem?</p> <p>Thanks again,<br/> Pauline</p> <p><a href="https://git.opendaylight.org/gerrit/#/c/5661/" class="external-link" target="_blank" rel="nofollow noopener">https://git.opendaylight.org/gerrit/#/c/5661/</a></p> <p>The NPE was thrown upon ErrorMessage without transactionUri. Most common reason for those errors is multipart stat request.</p> <p>merged</p> Development External issue ID 512 External issue URL Rank 0|i02yxr:
