java.lang.UnsatisfiedLinkError

Question

package SMDTest.conf;
import java.util.*;
public class AccessTimeRange {
public Vector TimeList; // must be Date
public Vector TimeRangeList; // must be DTimeRange public native int GetTimeRangeList(String DBPath, String DBEnv,
String NoteID, String FieldName); public native int SetTimeRangeList(String DBPath, String DBEnv,
String NoteID, String FieldName); static { System.loadLibrary("AccessTimeRange");
}
}运行时调用GetTimeRangeList 报Java.lang.UnsstisfiedLinkError这个异常，
程序是应该找到这个dll的，不知道为什么会出现这个问题。

Answer 2

java.lang.UnsatisfiedLinkError 未满足的链接错误。当Java虚拟机未找到某个类的声明为native方法的本机语言定义时抛出。 看来你缺少了某个 dll文件哦！

Answer 3

恩，你事先了native方法一定要用c或者其他语言提供这个方法。

Answer 4

javah 时使用完整包名.类名

Answer 5

用class生成的h文件，已经用于c，编译成了dll。
并且放在了目录下面

Answer 6

D:\testtoolsforDBScan-debug>cd SMDTestD:\testtoolsforDBScan-debug\SMDTest>cd confD:\testtoolsforDBScan-debug\SMDTest\conf>javac AccessTimeRange.javaD:\testtoolsforDBScan-debug\SMDTest\conf>cd ../..D:\testtoolsforDBScan-debug>javah SMDTest.conf.AccessTimeRangeD:\testtoolsforDBScan-debug>javah SMDTest.conf.AccessTimeRangeD:\testtoolsforDBScan-debug>javah SMDTest.conf.AccessTimeRange这个是我的编译头文件的命令，应该没有问题，也没有报错

Answer 7

应该不是找不到dll的问题，我将dll删除掉，提示的异常不同

Answer 8

dll文件必须是release的
是否是debug的?

Answer 9

是否你的dll,还依赖于其他的dll,如果需要一起放进去
