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"?>

<projectbasedir="."default="start_tomcat"name="Ch2WebApp">

    <propertyname="webDir"value="war"/>

    <propertyname="tomcat.home"value="D:/program/tomcat6"/>

    <pathid="classpath">

       <filesetdir="lib">

           <includename="*.jar"/>

       </fileset>

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

    </path>

 

    <pathid="runtime_classpath">

       <filesetdir="lib">

           <includename="*.jar"/>

       </fileset>

       <dirsetdir="classes"/>

    </path>

 

    <targetname="compile">

       <echomessage="compile"/>

       <mkdirdir="classes"/>

       <javacclasspathref="classpath"destdir="classes"srcdir="src"includeantruntime="on"fork="true"encoding="UTF-8"/>

    </target>

 

    <targetname="war"depends="compile">

       <deletefile="chapter2.war"/>

       <warbasedir="war"destfile="chapter2.war"webxml="war/WEB-INF/web.xml">

           <classesdir="classes"/>

           <zipfilesetdir="data"prefix="data"/>

           <zipfilesetdir="lib"prefix="WEB-INF/lib"/>

       </war>

      

       <deletedir="${tomcat.home}/webapps/chapter2"/>

       <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
