Apache Tomcat Native library路径找不到

koflover

　　在win平台上Eclipse中启动Tomcat时，报如下错误，原因是 java.library.path中找不到Tomcat的tcnative-1.dll库，才会报出The APR based Apache Tomcat Native library not found
信息: The APR based 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_20\jre\bin...　　

　　只需配置下环境变量即可,java.library.path的查找路径为系统的环境变量Path路径,而tcnative-1.dll文件在Tomcat的bin目录下，设置下面的PATH变量即可：
set PATH
CATALINA_HOME=D:\soft\apache-tomcat-6.0.41
PATH=%PATH%;%CATALINA_HOME%/bin　　

　　Java查找的class类是通过CLASSPATH设置，查找外部的dll或者so模块则通过 用户级参数java.library.path 来加载，不管是Linux还是win平台，都可以通过System.getProperties()来查看Java运行环境参数
public static void main(String[] args) {
// TODO Auto-generated method stub
      Properties p = System.getProperties();
      Set keys = p.keySet();
      for(Object key: keys){
          System.out.println(key.toString() + " : " + p.getProperty(key.toString()));
      }
}　　加载非class模块可以从下面两个方法进行加载
1.启动的时候添加参数
java   -Djava.library.path=PATH
2.在代码中架在你
System.load(PATH)
