I have a setting.java class and in this class I read my data from a file and I want to use this data with jsp:useBean in my index.jsp page.
this class code is bellow:
public class setting {
private boolean setstatus=false;
private String title="Test";
public boolean changeheader(String text) {
return true;
}
public boolean settitle(String text) {
return true;
}
public void getTitle() throws IOException{
BufferedReader br ;
try {
br = new BufferedReader(new FileReader("C:\\Users\\Farshid\\workspace\\STPT\\WebContent\\file\\title.txt"));
this.title = br.readLine();
System.out.println("\nline: " + this.title + "\n");
br.close();
} catch (FileNotFoundException e1) {
e1.printStackTrace();
System.out.println("Error");
}
}
}
And this is my index.jsp codes:
<%@ page language="java" contentType="text/html; charset=ISO-8859-1" pageEncoding="ISO-8859-1"%>
<!DOCTYPE html PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN" "http://www.w3.org/TR/html4/loose.dtd">
<html>
<head>
<meta http-equiv="Content-Type" content="text/html; charset=UTF-8">
<title>
</title>
</head>
<body>
<jsp:useBean id="settitle" class="com.stpt.project.setting" scope="page">
<jsp:getProperty property="title" name="settitle" />
</jsp:useBean>
</body>
</html>
And these are my errors:

description The server encountered an internal error that prevented it from fulfilling this request.
