Henrique:
With these lines you can read where the error came from. Truely I find
out that problem comes from net.sf.webcat.WCServletAdaptor.

Sources of Web-CAT. I installed WOLips + Web-Objects framework as I
read from wocommunity.org

I think that this error is due to a bug of WOLips37Stable while
generating "JAR Project". This because when trying to generate a new
"JAR Project" (or simply when accessing JAR project implementing
net.sf.webcat package) I get the same error described here [2]. So I
decided to replace this sources with pre-built jar got from
distributed war file of Web-CAT and it goes fine, without any
exception.
Here you can find some of the eclipse log:
this for creation of new JAR project:
