Причем раньше все работало,сервис создавался нормально. Причем ошибка повторяется, если генерируешь пустой проект и начинать создавать сервис. Единственное отличие в сообщении об ошибке это в имя пакета org.apache.axis.encoding.Serializer -Я стал искать вот этот пакет. не нашел просба сильно не пинать, я новичек. приходиться разбираться. Среда разработки Rational Software Architect. Помогите !
