我正在尝试实施JNA。我已将以下代码用于测试目的。现在我得到一个例外。如果我使用的方法不正确或者我的测试代码有任何问题,请纠正我。
我的类FileModifierLinux:
import com.sun.jna.Library;
import com.sun.jna.Native;
public class FileModifierLinux {
CLibrary libc = (CLibrary) Native.loadLibrary("c", CLibrary.class);
public void Update(String pth) {
libc.chmod(pth, 0755);
}
}
interface CLibrary extends Library {
public int chmod(String path, int mode);
}
我的页面:
<%
try
{
FileModifierLinux flx=new FileModifierLinux();
String pathX = getServletContext().getRealPath("/testpage.jsp");
flx.Update(pathX);
out.println("No Exception");
}
catch(Exception exp)
{
out.println("exp :"+exp);
}
%>
例外:
org.apache.jasper.JasperException: Unable to compile class for JSP

答案 0 :(得分:0)
你import
中的index.jsp
班级了吗?像:
<%@page import="com.somepackage.FileModifierLinux "%>
