运行JSP报表程序页面出现java.lang.UnsatisfiedLinkError: CC错误有以下几种原因和处理方法：1、请查看控制台的错误信息a:如果控制台的消息是类似java.lang.UnsatisfiedLinkError: no MRChkLib in java.library.path,Error loading library MRChkLib这样的错误信息
现象： java.lang.UnsatisfiedLinkError: Native Library xxx.dll already loaded in another classloader at java.lang.ClassLoader.loadLibrary0(ClassLoader.java:1551) at java.lang.ClassLoader.loadLibrary(ClassLoader.java:1511) at java.lang.Runtime.loadLibrary0(Runtime.java:788) at java.lang.System.loadLibrary(System.java:834) 分析： 这种错误在我们使用热启动方式发布某个使用了JNI技术的Web应用时，并将调用年native方法的jar包独立部署在该应用下面，当我们的Web应用有了更新以后，在调用到该jar包封装的native方法时，会抛出该错误。（以上OS为Windows，若是Linux或Unix，应该是xxx.so报错） 这是因为Web服务器已经在第一次加载该应用时，已经load了该dll，当该应用被再次热启动时，该dll将重新被加载，于是报错。 解决方案： 一、将含有JNI调用的jar包部署在Web服务器的公用lib库中。Web应用再发布时可以不用加载； 二、jar包部署不变，在该Web中实现一个listener，监听是否第一次启动，若不是第一次启动，屏蔽掉该jar包所含dll的加载。
public class UnsatisfiedLinkErrorTest {
public native void call_A_Native_Method();
static {
System.loadLibrary("myNativeLibrary");
}
public static void main(String[] args) {
new UnsatisfiedLinkErrorTest().call_A_Native_Method();
}
}

(1) MHP (Multimedia Home Platform) was developed by the DVB Project as the world's first open standard for interactive television. It is a Java-based environment which defines a generic interface between interactive digital applications and the terminals on which those applications execute. MHP was designed to run on DVB platforms but there was a demand to extend the interoperability it offers to other digital television platforms. This demand gave rise to
GEM, or Globally Executable MHP, a framework which allows other organisations to define specifications based on MHP.
