Mock IaaS is disabled Exception when starting Stratos
Hi,
I have <mock-iaas enabled="false"> in mock-iaas.xml and removed mock-iaas
related confings in cloud-controller.xml.
When I have a glance there was a service *MockIaasServiceComponent* which
tries to start MockIaaS at ativation process. MockIaaS is not compulsary?
is'it?

that's why this has happened. Now I have fix this by skipping Mock IaaS
service component activation if Mock IaaS is disabled.

Should this halt the startup? IMHO we can print a WARN log saying that mock
iaas is disabled and continue to start Stratos.

Re: Mock IaaS is disabled Exception when starting Stratos
Posted by Imesh Gunaratne <im...@apache.org>.
Hi Udara,
No, it should raise an error if someone is trying to use the Mock IaaS
without enabling it.
In this scenario what happens is Stratos is starting the Mock IaaS OSGi
bundle and the bundle is trying to create an instance of
MockIaasServiceImpl while it is disabled. I have now fixed this in master
branch.
Thanks

Re: Mock IaaS is disabled Exception when starting Stratos
Posted by Udara Liyanage <ud...@wso2.com>.
Hi Imesh,
I found the code snippet. It should be a warning message instead of
throwing an exception since a user should be able to use Stratos without
MockIaaS in case he is using another IaaS.
if(!MockIaasConfig.getInstance().isEnabled()) {
throw new RuntimeException("Mock IaaS is disabled, please check
the configuration");
}
