Bom Dia!

Criei um relatório pelo ireport usando javaBean, fiz a chamada usando um servilet e esta dando um exception

GRAVE: Servlet.service() for servlet [ServletReport] in context with path [/reports] threw exception java.lang.NullPointerException at br.com.cipolatti.infrastructure.servlets.ServletReport.service(ServletReport.java:82) at javax.servlet.http.HttpServlet.service(HttpServlet.java:722) at org.apache.catalina.core.ApplicationFilterChain.internalDoFilter(ApplicationFilterChain.java:304) at org.apache.catalina.core.ApplicationFilterChain.doFilter(ApplicationFilterChain.java:210) at org.apache.catalina.core.StandardWrapperValve.invoke(StandardWrapperValve.java:224) at org.apache.catalina.core.StandardContextValve.invoke(StandardContextValve.java:175) at org.apache.catalina.authenticator.AuthenticatorBase.invoke(AuthenticatorBase.java:462) at org.apache.catalina.core.StandardHostValve.invoke(StandardHostValve.java:164) at org.apache.catalina.valves.ErrorReportValve.invoke(ErrorReportValve.java:100) at org.apache.catalina.valves.AccessLogValve.invoke(AccessLogValve.java:851) at org.apache.catalina.core.StandardEngineValve.invoke(StandardEngineValve.java:118) at org.apache.catalina.connector.CoyoteAdapter.service(CoyoteAdapter.java:405) at org.apache.coyote.http11.Http11AprProcessor.process(Http11AprProcessor.java:257) at org.apache.coyote.AbstractProtocol$AbstractConnectionHandler.process(AbstractProtocol.java:515) at org.apache.tomcat.util.net.AprEndpoint$SocketProcessor.run(AprEndpoint.java:1764) at java.util.concurrent.ThreadPoolExecutor$Worker.runTask(Unknown Source) at java.util.concurrent.ThreadPoolExecutor$Worker.run(Unknown Source) at java.lang.Thread.run(Unknown Source)

este é meu servilet

[code]public class ServletReport extends HttpServlet {

private ServletContext sc;

private FactoryService factoryService = new FactoryService();

public void init(ServletConfig config) throws ServletException {
	super.init(config);

	sc = config.getServletContext();
	
	WebApplicationContext webApplicationContext = WebApplicationContextUtils.getWebApplicationContext(sc);

	AutowireCapableBeanFactory autowireCapableBeanFactory = webApplicationContext.getAutowireCapableBeanFactory();

	autowireCapableBeanFactory.configureBean(factoryService,"FactoryService");;

}

@SuppressWarnings("unchecked")
protected void service(HttpServletRequest request,
		HttpServletResponse response) throws ServletException, IOException {
	
	List<?> dados = new ArrayList();
	File reportFile = null;		
	HashMap parameters = new HashMap();
	
	String acao = request.getParameter("acao");
	String where = request.getParameter("where");
	
	if (acao.equals("chkGeral")) {		   
		dados = factoryService.relatorioCheckListService.filterReport(where);
		reportFile = new File(sc.getRealPath("WEB-INF/reports/chkGeral.jasper"));
	}
	
	if (acao.equals("memorial")) {		   
		dados = factoryService.relatorioMemorialService.filterReport(where);
		reportFile = new File(sc.getRealPath("WEB-INF/reports/memorial.jasper"));
	}
	
	byte[] bytes = null;			
	
	JRDataSource jrds = new 
	JRBeanCollectionDataSource(dados);
	
	try {
		bytes = JasperRunManager.runReportToPdf(reportFile.getPath(),parameters, jrds);
		
	} catch (JRException e) {
		e.printStackTrace();
	}

	if (bytes != null && bytes.length > 0) {
		response.setContentType("application/pdf");
		response.setContentLength(bytes.length);
		ServletOutputStream ouputStream = response.getOutputStream();
		ouputStream.write(bytes, 0, bytes.length);
		ouputStream.flush();
		ouputStream.close();
	}		
	
}[/code]

o erro o corre nesta linha
bytes = JasperRunManager.runReportToPdf(reportFile.getPath(),parameters, jrds);

Grato.
