[rules-users] FactType returns null when creating a java client on Eclipse invoking a rule in Guvnor

Hi all, I have imported the mortgage-sample-repository.xml to my guvnor instance. Its okey. Then I tried to run the MortgageClientExample java class. Everything is okey, but when I try to create the FactType "FactType appType = kbase.getFactType("mortgages", "LoanApplication");" I have null as the result for the appType variable. The KnowledgeBase is okey also. I used the same configurations of the example that comes with guvnor download. I am in Windows with Tomcat 7. I appreciate any help. TIA
