and properties in files not there, once open file after exception.
any idea?
i resolved problem. can't write in propertie file in class path, because in classpath part of war-file on server. , after write data not consistent more. error. solution put propertie file out of classpath. used fileoutputstream write propertie file , use eclipse home path path. solution or should use diffrent way write in propertie file?
