请问Java调用iReport还要引用什么包吗？

[Wnyu]

我用iReport, 报表格式已做好， 然后想java调用，　在网上找了一段代码如下：
<%@ page import="dori.jasper.engine.*" %>
<%@ page import="java.util.*" %>
<%@ page import="java.io.*" %>
<%@ page import="java.sql.*" %>

<%
File reportFile = new File(application.getRealPath("test3.jasper"));

Map parameters = new HashMap();
Connection conn=null;

//以下忽略得到数据库连接过程
//……

byte[] bytes =
JasperRunManager.runReportToPdf(
reportFile.getPath(),
parameters,
conn
);

response.setContentType("application/pdf");
response.setContentLength(bytes.length);
ServletOutputStream ouputStream = response.getOutputStream();
ouputStream.write(bytes, 0, bytes.length);
ouputStream.flush();
ouputStream.close();
%>

但编译是总出错，　提示为：
"jsp4.jsp": Error #: 704 : cannot access directory dori\jasper\engine
"jsp4.jsp": Error #: 300 : variable JasperRunManager not found in class jsp4_0002ejsp_jsp at line 18

请问Java调用iReport还要引用什么包吗？

这又是什么问题呀。

[OnlyFor_love]

路过！

你要将含有包dori.jasper.engine的jar文件引入到你工程的构建路径中。


如果这个包是以jar文件形式存在的话。

[Wnyu]

请问dori.jasper.engine的Jar在什么地方。 我就是找不到呀。

[Wnyu]

up, 急呀，在Jar什么地方， 我找到它就行了。 100分！

[Wnyu]

还是自已搞掂了， 这世界上救人不知救己呀。。。。。无奈。。。。。结账。。。。。
