Re: [Engine-devel] Error on starting webadmin

Hi, I've updated http://www.ovirt.org/Building_Engine_Draft - added section "Engine local configuration" (feel free to edit or modify as necessary)

However, the root cause of this issue is LocalConfig class (machine-specific Engine configuration) throwing exception in following cases: - cannot load default properties (ENGINE_DEFAULTS property if defined, otherwise /usr/share/ovirt-engine/conf/engine.conf.defaults) - cannot load custom properties (ENGINE_VARS property if defined, otherwise /etc/sysconfig/ovirt-engine) - requesting missing property value (LocalConfig.getProperty method) (Note that UI plugins use two Engine properties: ENGINE_USR and ENGINE_ETC.) As Juan suggests in his comment in http://gerrit.ovirt.org/#/c/10026/, we could include this in "building Engine" wiki. For example: - have ENGINE_DEFAULTS property point to OVIRT_HOME/backend/manager/conf/engine.conf.defaults (alternatively, users can copy this file to /usr/share/ovirt-engine/conf) - create custom Engine config file, e.g. ~/myengine.conf, and have ENGINE_VARS property point to this file Vojtech ----- Original Message ----- From: "Daniel Erez" <derez(a)redhat.com&gt; To: "Moti Asayag" <masayag(a)redhat.com&gt; Cc: engine-devel(a)ovirt.org Sent: Thursday, December 13, 2012 11:49:13 AM Subject: Re: [Engine-devel] Error on starting webadmin ----- Original Message ----- > From: "Moti Asayag" <masayag(a)redhat.com&gt; > To: engine-devel(a)ovirt.org > Sent: Thursday, December 13, 2012 12:25:07 PM > Subject: [Engine-devel] Error on starting webadmin > > Hi, > > I get the following error when trying to connect to webadmin: > > 2012-12-13 11:57:06,689 ERROR > [org.apache.catalina.core.ContainerBase.[jboss.web].[default-host].[/webadmin].[WebAdminDynamicHosting]] > (http--0.0.0.0-8700-1) Servlet.service() for servlet > WebAdminDynamicHosting threw exception: > java.lang.IllegalArgumentException: The property "ENGINE_USR" > doesn't have a value. > > It caused by the PluginDataManager instantiation which requires > several variables to be defined. > > In order to by pass those errors do: > 1. create a file /usr/share/ovirt-engine/conf/engine.conf.defaults > 2.
