项目启动报出来的，能够正常启动。

The Apache Tomcat Native library which allows optimal performance in production environments was not found on the java.library.path: C:\Program Files\Java\jdk1.6.0_10\bin;E:\Tomcat 6.0\bin

求具体告知是什么原因导致的。需要下载tcnative-1.dll。到tomcat bin目录下吗。

应该是下载到下面两个目录的任意一个就可以了。
C:\Program Files\Java\jdk1.6.0_10\bin
E:\Tomcat 6.0\bin

具体的说明，可以参考The APR based Apache Tomcat Native library which allows optimal performance in production environments was not found on the java.library.path: E:\JavaTool\jdk1.6.0_24\bin;E:\JavaTool\apache-tomcat-6.0.35\bin
