birt

I need to create a report capability(function) in an existing spring boot web application. The suggestion was to use BIRT, which I could integrate with the spring boot web app. I found the article below and was able to run the reports in a spring boot starter project (using http://start.spring.io/ ). This article, fairly old, did help me to get to a working example. https://spring.io/blog/2012/01/30/spring-framework-birt . This article is basically exactly what I want, but in a spring boot web app. The challenge I have is to run the report using the BIRT viewer, which comes with nice

Backgroud: Use Java + BIRT to generate report. Generate report in viewer and allow user to choose to export it to different format (pdf, xls, word...). All program are in "Layout", no program in "Master Page". Have 1 "Data Set". The fields in "Layout" refer to this DS. There is Group in "Layout", gropu by one field. In "Group Header", I create one cell to use as page number. "Page : MyPageNumber". "MyPageNumber" is a field I define which would +1 in Group Header. Problem: When I use 1st method to generate report, "MyPageNumber" could not show correctly. Because group header only load one time

I am using eclipse brit plugin to generate a line chart. Basically i want to create a report to present a mobile battery usage in given time range. Here is sample data where observationtime is dynamic based on user selected range: I want to draw a line chart of per device but unable to find any configuration to draw different charts per device on same report page. Can someone help me on this ? ------------------------Update configuration and result----------------- ------------ after using list ----------- I the "Select Data" tab of your chart, select the time for the Category (X) Axis, The

I created a report using BIRT and some dynamic fields are HTML values, which come from backend systems, but when I try to generate a PDF report with HTML embedded image - then it shows: "The resource of this report item is not reachable." instead of image. Is there any solution to render embedded image in PDF? It works fine in HTML. I found a solution, how to render images in PDF, which are embedded in HTML content. The problem was with BIRT library ResourceLocatorWrapper class. I changed method: public byte[] findResource(ModuleHandle design, String fileName, int fileType, Map appContext);

birt报表部署方式有两种，一种是通过官方提供的WebViewerExample webapp去部署 另一种是通过ReportEngine API自行开发部署程序； 采用第一种的好处是不需要编写额外的代码，直接就能部署，比较方便，但是限制很多 如果采用第二种的话就很灵活了。 本日志主要记录采用ReportEngine API来进行报表的部署； 编码前准备： 下载birt-runtime-version.zip(www.eclipse.org有下载) 解压，其中ReportEngine目录存放着所有所需的东西 准备数据库驱动 编写birt报表文件 利用下边的代码就可以执行报表文件并生成目标html文件 package report; import java.util.HashMap; import java.util.logging.Level; import org.eclipse.birt.core.framework.Platform; import org.eclipse.birt.report.engine.api.EngineConfig; import org.eclipse.birt.report.engine.api.EngineConstants; import org.eclipse.birt.report.engine.api.EngineException;

至于为什么使用BIRT我想在这里也不用过多说明了，公司从去年底（2013年）开始引入了BIRT，使用过程中也比较顺利，对于技术人员也比较容易上手。 使用BIRT做的第一个主要工作就是将原有项目中的报表分离为独立的服务（原有项目历时时间较久，且项目很大，各类报表有近百张，全是通过累代码的方式处理的，其实这个项目是做业务处理的，只不过也有报表要求，如此多的功能叠加给系统造成了极大的压力）。 报表顺利开发完成，可是部署时遇到了麻烦，由于项目很大，现场是使用集群部署的（4台WEB），本打算单独部署一个BIRT服务器用于报表展示，业务系统的4台WEB直接访问BIRT服务器，此时就出现了令人讨厌的 The viewing session is not available or has expired “聪明的”技术人员查阅了一些资料后确定此问题为BIRT的BUG，将BIRT服务与项目服务部署在一起即可解决，这个方案当然会受到现场运维人员的极力反对，此后一度陷入僵局，技术人员无法解决，现场人员不愿意按此部署。 按照经验，session无效或者过期一般都是客户端设置问题，比如安全级别、隐私设置等等，于是去瞄了一眼，发现浏览器确实报错了： 果然是cookie设置问题！cookie禁用导致session无效，允许会话cookie，设置完就可以访问了： 坑爹啊，耗了一周了呀！ 当然了

I need to create a global report variable to get a variable of my first table, then use it in my last table to do a calculation. I'm new with BIRT and don't found a guide to do it. Someone can explain me how I can do it ? We initialize a global report variable in "Variables" section of the outline view: Then we can set and get its value from any place of the report: myvalue=vars["myGlobalVariable"]; vars["myGlobalVariable"]=myvalue; Notice global variables we declare like this are also available in the expression builder, which is very convenient. 来源： https://stackoverflow.com/questions
