在浏览器生成PDF文件，主要用了JasperRunManager对象面的runReportToPdfStream方法，在WEB里一般都先用iReport生成jasper文件，这样就去解析JRXML文件了
例子如下
import java.io.IOException;import java.io.InputStream;import java.io.PrintWriter;import java.io.StringWriter;import java.util.HashMap;import javax.servlet.ServletException;import javax.servlet.ServletOutputStream;import javax.servlet.http.HttpServlet;import javax.servlet.http.HttpServletRequest;import javax.servlet.http.HttpServletResponse;import net.sf.jasperreports.engine.JREmptyDataSource;import net.sf.jasperreports.engine.JRException;import net.sf.jasperreports.engine.JasperRunManager;public class JasperReportServlet extends HttpServlet { private static final long serialVersionUID = 1L; public void doGet(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException { //获得输出流 ServletOutputStream outputStream = response.getOutputStream(); //获得输入流 InputStream inputStream = getServletConfig().getServletContext().getResourceAsStream("JasperFile//JasperReportFile.jasper"); try { //生成网页的PDF文件 JasperRunManager.runReportToPdfStream(inputStream, outputStream, new HashMap(), new JREmptyDataSource()); //设置PDF格式 response.setContentType("application/pdf"); outputStream.flush(); outputStream.close(); } catch (JRException e) { StringWriter stringWriter = new StringWriter(); PrintWriter printWriter = new PrintWriter(stringWriter); e.printStackTrace(printWriter); response.setContentType("text/plain"); response.getOutputStream().print(stringWriter.toString()); } } public void doPost(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException { this.doPost(request, response); }}
