Thaks for your answers Mat. I guess you may be right. The log for the "serious problem" is before the sucesfull request. I'll double check our initialization code, but on local server all our developers are running and debugging the app properly, so it may be a singular initialization problem that may be happening only in production.
I'll try starting the devserver and, immediately after the app is initialized, access the erroring servlet to see if I find something diferent. When testing, we usually access the index.jsp url at first run of the local instance, so there may be something wrong in the servlet/jsp that is erroring. I'll post back soon.
