Tomcat下使用JMagick的问题!

mageMagick一个优秀的图像处理软件，JMagick是对ImageMagickJAVA面向对象化包装。我在TomCat下使用JMagick的时候报错信息:

我已安装IImageMagic WINDOWS的包，安装完结之后，把安装目录下所有的DLL都拷贝到system32下面了.
将jmagick.jar文件导入到lib中，将jmagick.dll文件也放到SYSTEM32目录下.
在调用JMagick的class里加了
System.setProperty("jmagick.systemclassloader","no");代码如下:

public static boolean resize(String picFrom, String picTo, int width, int height, boolean scale) throws MagickException {
System.setProperty("jmagick.systemclassloader","no");
        ImageInfo info = null; 
      try
      {     
      if(new File(picFrom).exists())
          {
          info = new ImageInfo(picFrom);
          }
          MagickImage image = new MagickImage(new ImageInfo(picFrom));
          MagickImage scaled;

          if (!scale) {
                  scaled = image.scaleImage(width, height);
          } else {
              Dimension dimension = image.getDimension();
              int iWi = (int) dimension.getWidth();
              int iHi = (int) dimension.getHeight();

              if(iWi <= width && width > 0) {
                  return false;
              }

        }
      ......
      ..............................

可是依然出现这个错误不知道为什么,请大虾指较.在线等,急....................

系统环境:XP,JDK1.5,Tomcat 5.5


我也遇到了您的问题 整了一夜,找到个解决方法但不知道是不是最好的。
就是把jmagick.dll 复制一份到tomcat/bin 目录中
我试了试 System.setProperty("jmagick.systemclassloader","no"); 这句代码都不用要就可以执行
希望对您有用
