Pentaho Report Designer 入門教程(三)
采用Pentaho Report Designer5.1版本，也是最新的版本。
一、 安裝和介紹
介紹部分內容略，首先安裝jdk，并配置java相關環境變量，下載pentaho report并解壓，直接運行即可。
二、 第一個示例
三、在Swing程序中集成
四、在j2ee程序中集成
? 新建web項目
? 編寫ant腳本，編譯運行項目

</project>
? 測試通過servlet 訪問不同文件格式的報表
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文件調用servlet
