jmagick在Application中使用正常,但在WEB里使用却提示出错,如何解决??

ava.lang.UnsatisfiedLinkError: no JMagick in java.library.path
java.lang.ClassLoader.loadLibrary(ClassLoader.java:1517)
java.lang.Runtime.loadLibrary0(Runtime.java:788)

这是在Tomcat下运行的错误信息,在Resin里试过也是一样的.我已经按网上说的在最前面加上System.setProperty("jmagick.systemclassloader","no");了,但还是没有加载jmagick.dll进来,请问到底还差什么????????
