在plugin中用engine api引入BIRT已经设计好的rptdesign文件
<div class="postText">这个方法直接放到rcp下运行不了，几天过去才发现是个多么愚蠢的错误：在plugin.xml的dependiences添加org.eclipse.birt.report.viewer, org.eclipse.birt.core, org.eclipse.birt.report.engine, org.eclipse.birt.report.model等你需要的所有包后记得在自己的run--->configure-->plug-ins 里面把所有的birt都打上勾，否则运行会出错的1，用birt设计rptdesign文件
（1）下载 birt framwork plugin放到eclipse目录下
（2）创建一个报表工程并制作一个报表（即rptdesign文件）
2，安装birt engine
下载 birt runtime 到任意目录，
3，创建一个java project 设置build 属性，使之包含birt 的core和report.engine，并把Report engine目录下的jar加到jar属性中
工程代码如下，其中几个路径根据自己配置设置：
