Loading stopped- Overview tab

[mva1991]

Hello Guys,
I have installed OpenEMM on my RHEL following all the steps given in the Installation manual.
When I login into the application, I find

" loading stopped. A general error occurred. Please check your input."

Where does this error point to? Even after two attempts of installation the same error message looks recurrent on my overview tab.
Please help me with this issue.
Thanks,
mva1991

You should have a look at Tomcat's log catalina.out.
