Selenium Appian API JAVA

Hi all, I have the following code: 

it runs up until  fixture = new SitesFixture(); than i get this error:

it says something about log4j manager missing but i didn't implement that. also i tried adding the log4j jar files from apache but still got the same error. 

any help is greatly appreciated. Thank You!
