Can't find library QMapLServer.DLL
java.lang.UnsatisfiedLinkError: no QMapLServer in java.library.path

请问如何解决。

[waterStreaming]

解决，就是把.dll放在String path=System.getProperty("java.library.path");所能指出的路径下。
..\Apache Software Foundation\Tomcat 5.5\bin或../../system32

[s_Prince]

当 Java 虚拟机无法找到声明为 native 的方法的适当本地语言定义时，抛出该错误

[waterStreaming]

那该如何解决？

UnsatisfiedLinkError是由于系统找不到JNI所需的某个DLL文件，
可以将所有DLL放在系统path能找到的地方，建议目录为system或system32.

或者你坚持一下
javah 时有没有使用完整包名.类名
没加包名也会报这种错误
