最近要开发比较复杂的报表，选来选去最终选择birt报表，由于对birt不是很熟，选择开发工具，一种是直接使用eclipse +birt插件，但是发现很多eclipse版本集成birt后无法打开预览(Preview)选项:
另外一种是使用myeclipse 的web报表,因为myeclipse的web report 也是集成的birt，但是选用myeclipse后发现也有的办法无法使用Preview选项，最终选择myeclipse 2014，这个版本可以Preview,但是使用向导创建Report web Project后，不创建报表直接部署，tomcat启动就报如下错误:

这个问题我找了很多原因，一直无法解决(总想myeclipse集成的应该不会有问题，是自己本机环境问题，所以一直无法解决)，后来没办法直接下载birt对应运行时(myeclipse 2014集成运行时4.3.1):org.eclipse.birt.runtime_4.3.1.v20130918-1142.jar,替换web项目lib中对应的birt runtime jar，问题解决.
