Pentaho Report Designer 入门教程(三)
采用Pentaho Report Designer5.1版本，也是最新的版本。
一、 安装和介绍
介绍部分内容略，首先安装jdk，并配置java相关环境变量，下载pentaho report并解压，直接运行即可。
二、 第一个示例
三、在Swing程序中集成
四、在j2ee程序中集成
? 新建web项目
? 编写ant脚本，编译运行项目
<?xml version="1.0"encoding="UTF-8" standalone="no"?>

<propertyname="webDir"value="war"/>
<propertyname="tomcat.home"value="D:/program/tomcat6"/>
<pathid="classpath">

</fileset>
<filesetfile="${tomcat.home}/lib/servlet-api.jar"/>

<deletefile="${tomcat.home}/webapps/chapter2.war"/>
<copyfile="chapter2.war"todir="${tomcat.home}/webapps"/>
</target>
<targetname="start_tomcat"depends="war">
<exectimeout="1000"dir="${tomcat.home}/bin"executable="${tomcat.home}/bin/shutdown.bat"/>
<sleepseconds="2"/>
<execdir="${tomcat.home}/bin"executable="${tomcat.home}/bin/startup.bat"/>
</target>
</project>
? 测试通过servlet 访问不同文件格式的报表
publicvoid init(ServletConfig config)throws ServletException {
ClassicEngineBoot.getInstance().start();
super.init(config);
}
protectedvoiddoGet(HttpServletRequest request,
HttpServletResponse response)throws ServletException, IOException {
try {
ResourceManager manager =new ResourceManager();
manager.registerDefaults();
String reportPath = "file:"
+ this.getServletContext().getRealPath(
"data/ch2_1.prpt");
Resource res =manager.createDirectly(newURL(reportPath),
MasterReport.class);
MasterReport report = (MasterReport)res.getResource();
// determine the output format and renderaccordingly
String outputFormat =request.getParameter("outputFormat");
if ("pdf".equals(outputFormat)) {
// render thepdf
response.setContentType("application/pdf");
PdfReportUtil.createPDF(report,response.getOutputStream());
} elseif ("xls".equals(outputFormat)) {
// render in excel
response.setContentType("application/vnd.ms-excel");
ExcelReportUtil.createXLS(report,response.getOutputStream());
} elseif ("rtf".equals(outputFormat)) {
// render inrtf
response.setContentType("application/rtf");
RTFReportUtil.createRTF(report,response.getOutputStream());
}
} catch (Exception e) {
e.printStackTrace();
}
super.doGet(request, response);
}
? jsp或html文件调用servlet
