用于创建Pentaho报告的Java代码，此报告接受输入作为数据集成(.ktr)文件 [英] Java code for creating Pentaho reports and this reports accept input as data integration(.ktr) file

问题描述

我正在寻找Java代码，其中必须将HTML/PDF格式的Pentaho报告与数据集成(.ktr文件)一起显示为Pentaho报告的输入.

I am looking for java code in which have to display Pentaho reports in HTML/PDF format with Data Integration(.ktr file) as input to the Pentaho reports.

推荐答案

首先，最有可能是API的官方文档，其中一章为" 将报告引擎嵌入Java应用程序 "

First of all most probably there is official documentation to API, chapter "Embedding the Reporting Engine Into a Java Application"

编码非常简单

使用可视化工具创建报告，将数据源分配为.ktr文件，并以示例中的代码为例.

Create report using visual tool, assign data source as .ktr file, and code as example in tutorial.

只有您可能需要自定义* .ktr文件的路径，该路径可以通过官方API创建(很有可能)，也可以在开始报告之前准备报告* .prpt.

Only u might need to customize path to *.ktr file which either can be made via official API (most probably) or prepare report *.prpt before to start report.

Pentaho Report Designer生成带有prpt扩展名的文件，这只是一个内部包含许多xml文件的zip文件.因此，您需要解压缩(java.util.zip)，并将其解压缩到文件 datasources 的文件Kettle-ds.xml中.使用任何合适的xml解析器将路径更改为* .ktr文件，并将其打包回来.然后将自定义报告传递给报告引擎.

Pentaho Report Designer generate files with prpt extension which is just a zip file with a lot of xml files inside. So u need to unpack it (java.util.zip) and inside in folder datasources file kettle-ds.xml. Use any suitable xml parser to change path to *.ktr file and pack it back. Then pass customized report to report engine.
