I was installing Order Entry UI module to my reference application … After installing it completely , “Prescribed Medication” appeared on user details page and by clicking on it " The origin server did not find a current representation for the target resource or is not willing to disclose that one exists. Apache Tomcat/9.0.26 " gave me this error . I thought it might be installation problem so i reinstalled it , still it is giving me the same error. Any Solution ??
