Ajuda não encontra aqruivo jrxml para compilar ..alguém pode me ajudar

Olá,

não pensei que fosse dificil integrar jasper com java pois fiz o relatório em ireport 4.0.0
mais estou usando framework com maven pois altero pra atualizar a versão 4.0.0 e não atualiza
fica com a versão 3.1.

E agora quero compilar via jasper mais não encontra o arquivo jrxml alguém pode me ajudar …

minha estrutura de diretorio com maven via web está assim :

src

  - main
      - webapp
      - jasperreports
         - respostaprofessor.jrxml
         -META-INF
         - privates
String jasper =getRequest().getContextPath()+ "/jasperreports/respostaprofessor.jrxml";
		 String host = "http://" + getRequest().getServerName() + ":" + getRequest().getServerPort();
	     URL jasperURL        = new URL(host + jasper);
		 JasperDesign design = JasperManager.loadXmlDesign(jasperURL.getFile() );    
			
		 JasperReport jr = JasperManager.compileReport(design);
