最近接触报表，使用Birt报表，还不错！一点小总结：
Birt部署，只是添加jar而已。
下载相应的runtime架包，单独解压birt.war
在项目中的WEB-INF下新建report-engine文件夹（可自定义），拷贝文件如下：logs、scriptlib、images、documents（需要自己创建，版本中没有，用来缓存document）.
拷贝WEB-INF文件夹除了web.xml以外的xml以及properties文件和wsdd文件，顺便把lib中的架包放到位置
拷贝tlds下的birt.tld文件到项目tld文件夹
拷贝webcontent到项目WEB下或者WEBCONTENT下（不必奇怪WEBCONTENT/WEBCONTENT,报表需要
）
接下来，web.xml文件配置，添加如下代码：

还没完：
在jsp-config标签中添加
<taglib>
<taglib-uri>/birt.tld</taglib-uri>
<taglib-location>/WEB-INF/tld/birt.tld</taglib-location>
</taglib>
如此，配置完成！
调用如下代码：展示报表，
