Unable to access BRMS designer

Hi,

I am trying to setup BRMS along with the designer wars using the deployable-ee6 package provided by Red Hat.

BRMS is working fine but I am not able to create ruleflows since the interface is not opening up.

The designer war is not loading properly I guess, whenever I access it, below is the series of messages that are generated in the log and the screen doesnt load up.

Can anyone suggest any remedy?

Thanks!
