Did you put your .dlls into your */windows/system32* directory?

> public native boolean waitForAnyFile(String directrory);

> And upper branches (file path : C:\Tomcat5.5\webapps\ROOT\JNI\WEB-INF

> import java.io.*;
> class usepackage{

> Test t = new Test ();
> t.print(" JAVA ");
> t.readFile("Text.txt");

> After the Test. Java & run.java compile and run the following command
> and I got across the error:
> C:\Tomcat5.5\webapps\ROOT\JNI\WEB-INF\classes >java run
> Exception in thread "main" java.lang.UnsatisfiedLinkError: print
> at ver.callmydll.print(Native Method)
> at usepackage.main(usepackage.java:8)
> How do you fix the error ???
