eclipse 中发布birt的web项目到tomcat 中
报错1：
The Apache Tomcat Native library which allows optimal performance in production environments was not found on the java.library.path:C:\Program Files\Java\jre1.6.0_03\bin;C:\eclipse\plugins\com.genuitec.eclipse.easie.tomcat.myeclipse_6.0.1.zmye...........................等

解决：
1.eclipse中jdk的版本和本机环境变量中配置的jdk不相否
你的类编译的环境和执行的环境不是同一个JDK版本。

2.
下载   http://tomcat.heanet.ie/native/1.1.2/binaries/win32/tcnative-1.dll
放在tomcat\bin里  和C:\windows\system32下面

重启tomat eclipse
