Answer 1

我在控制台用
String a=reportFile.getPath();
System.out.println("url:"+a);
物理路事是正确的怎么却找到不到文件啊？

Answer 2

首先，看page.jasper的路径放的对吗？
其次，TOMCAT的字符集是ISO8859-1，在传值后要进行转换。

Answer 3

换了个jasperreports-0.6.5.jar就没问题了，但又出现了新问题

相对应我把包的引入也改了但怎么还时出错啊？

//报表编译之后生成的.jasper 文件的存放位置
File reportFile = new File(application.getRealPath("page.jasper"));
//这个是用来联接我的mysql 的JDBC URL
String url="jdbc:mysql://localhost/zhangbo";
Class.forName("org.gjt.mm.mysql.Driver").newInstance();
//传递报表中用到的参数值
Map parameters = new HashMap();
//"Name"是报表中定义过的一个参数名称,其类型为String 型
parameters.put("name","zhangbo");
System.out.println("---------conn yym-------------");
//连接到数据库
  Connection conn = DriverManager.getConnection(url,"root","");
System.out.println("---------Jasper begin-------------");
//在控制台显示一下报表文件的物理路径
System.out.println(reportFile.getPath());
try{
byte[] bytes=JasperRunManager.runReportToPdf(reportFile.getPath(),parameters,conn);
//byte[] bytes=JasperRunManager.runReportToHtmlFile(reportFile.getPath(),parameters,conn);
}
catch(Exception e){
e.printStackTrace();
}
//System.out.println("---------Jasper end-------------");
/*response.setContentType("application/pdf");
response.setContentLength(bytes.length);
ServletOutputStream ouputStream = response.getOutputStream();
ouputStream.write(bytes, 0, bytes.length);
ouputStream.flush();
ouputStream.close();*/

Answer 5

上面的问题自己也解决了
org.apache.jasper.JasperException: Unable to compile class for JSPAn error occurred at line: 10 in the jsp file: /MyJsp.jsp
Generated servlet error:
D:\java\jakarta-tomcat\work\Catalina\localhost\WebRoot\org\apache\jsp\MyJsp_jsp.java:87: cannot resolve symbol
symbol  : variable bytes  
location: class org.apache.jsp.MyJsp_jsp
ouputStream.write(bytes,0,bytes.length);
                  ^

ouputStream.write(bytes,0,bytes.length);但用ouputStream.write(bytes, 0, bytes.length);就抱错了是什么原因啊？

将junitruntime.jar(在eclipse\plugins\org.eclipse.jdt.junit.runtime_3.0.2目录中)
加入classpath中即可.

大家可以用weblogic试试
编译没有问题
可是在运行时出现了新问题
JSP页面中出现乱码 JSP中引用<%@ page contentType="text/html;charset=GB2312"%>运行
