Using DLL in Java

[smh]

I have a working sample program on how to use DLL in java with JNI. I use to be properly implemented:

/* Test.java */
public class Test {
    /*Load the dll that exports functions callable from java*/
    static {System.loadLibrary("TestImp");} /* Name Of DLL : TestImp.dll */
    /*Imported function declarations*/
	public native void print(String msg);
	public native byte[] readFile(String path);
	public native int searchFile(String path, byte[] b, int bLength);
	public native String[] findFiles(String path, String mask);
	public native String[] checkProcess(String processName, boolean killIt, boolean printOutput);
	public native int startProcess(String commandLine, String workingDir);
	public native boolean waitForFileMask(String directrory, String fileMask);
	public native boolean waitForAnyFile(String directrory);
	public void Test() {
   		 }
 	public static void main(String [] args) {
		Test t = new Test();
      		  /*Printf example*/
			t.print("->Testing JNI - Hello from \n");
        		/*Loading a file as a byte array example*/
			System.out.println("->Start Open  file Text.txt\n" + new String(t.readFile("Text.txt")));
   		  /*Printf example*/
			t.print("->Finish Sample \n");
       		 }	
}

So you see that the package was not Test.java, these programs have changed as follows:
(file path : C:\Tomcat5.5\webapps\ROOT\JNI\WEB-INF\classes\ver)

/* Test .java*/
package ver;
public class Test {
    /*Load the dll that exports functions callable from java*/
    static {System.loadLibrary("TestImp");} /* Name Of DLL : TestImp.dll */
    /*Imported function declarations*/
	public native void print(String msg);
	public native byte[] readFile(String path);
	public native int searchFile(String path, byte[] b, int bLength);
	public native String[] findFiles(String path, String mask);
	public native String[] checkProcess(String processName, boolean killIt, boolean printOutput);
	public native int startProcess(String commandLine, String workingDir);
	public native boolean waitForFileMask(String directrory, String fileMask);
	public native boolean waitForAnyFile(String directrory);
	public void Test() {
   		 }
}

And upper branches (file path : C:\Tomcat5.5\webapps\ROOT\JNI\WEB-INF\classes) made the following file:

/*run.java*/
import ver.*;
import java.io.*;
class usepackage{
	public static void main(String [] args) {
	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)

TestImp.dll Test.java file in System32 and the next there.
How do you fix the error ???

I won't email you; you write here you read here; if you change the package of your class the native code names also change. Your print() method has a different name now; you should change those names in your C/C++ code and recompile everything. (for the 'new' names read the generated .h file).

kind regards,
