IllegalStateException: getOutputStream() when creating oracle connection pool in glassfish
Actually I faced the same problem on windows, and it resolved be delete my glassfishe from Prgramfile folder and download new version from http://download.oracle.com/glassfish/4.0/promoted/glassfish-4.0-b87.zip and extract it where you want but not in programfile beacuse it need admin rolland then creat new server.
