我装了Crystal_Reports_XI_Release_2和myeclipe ，现在做了两个jsp页面，在安装的Crystal_Reports_XI_Release_2目录下
就是在C:\Program Files\Business Objects\Common\3.5\java\lib 下把jar包都拷到项目CR/WebRoot/WEB-INF/lib下

report_source.jsp ：

<%@ page language="java" import="java.util.*" pageEncoding="GB2312"%>
<%
String path = request.getContextPath();
String basePath = request.getScheme()+"://"+request.getServerName()+":"+request.getServerPort()+path+"/";
%>
<%@page import= "com.crystaldecisions.reports.sdk.* " %>
<%@page import="com.crystaldecisions.sdk.occa.report.lib.*" %>

try{
//打开报表
ReportClientDocument reportClientDoc = new ReportClientDocument();
reportClientDoc.open(REPORT_NAME, 0);
//把报表源放进session,传递到报表显示页面
session.setAttribute("reportSource", reportClientDoc.getReportSource());

//转到报表显示页面
response.sendRedirect("CrystalReportViewer.jsp");

}
catch(ReportSDKException ex){
out.println(ex);
}

out.println(ex);

CrystalReportViewer.jsp ：
