请教 class的问题

[iwantin]

我自己写了一个class，然后在jsp中调用，结果报错，错误如下：

Generated servlet error:
bad class file: D:\Tomcat\shared\classes\shecasafeapi\ReadConfInfo.class
class file contains wrong class: ReadConfInfo
Please remove or make sure it appears in the correct subdirectory of the classpath.


我得class的内容如下：

import java.io.*;
public class ReadConfInfo
{
public static void main(String[] args)
{
System.out.println("Hello World!");
}

private String filePath;
private BufferedReader file;
public void setFilePath(String Path)
{
filePath = filePath;
}

public String getValue(String strTitle)
{
String strLine;
String strValue = null;
String strTmp;
char FirstChar;
int nIndex;
try
{
file = new BufferedReader(new FileReader(filePath));
}
catch (IOException e)
{
System.out.println("读文件错误");
return null;
}

try
{
while( (strLine = (file.readLine()).trim() )!=null)
{
if ((strLine.length()) != 0)
{

FirstChar = strLine.charAt(0);
if ( (FirstChar != '`') && (FirstChar != '#') && (FirstChar != '['))
{
strTmp = strTitle;
nIndex = strLine.indexOf(strTmp);

}
}
}
}
catch(IOException e)
{
return null;
}

return strValue;


}

}

ReadConfInfo没有包名，应该放在\shared\classes\下面或者web-inf/classes下面，不过最好有一个包名，这样就可以建立对应的目录

[iwantin]

我把class 放在了shecasafeapi下面，然后，调用的页面如下：

<%@ page import="shecasafeapi.*" %>
<%@ page import="java.util.*"%>
<%@ page contentType="text/html; charset=gb2312"%>

<%

shecasafeapi.ReadConfInfo rf = new shecasafeapi.ReadConfInfo();


%>

错误如下：

D:\Tomcat\work\Catalina\localhost\_\org\apache\jsp\test\testfile_jsp.java:50: cannot access shecasafeapi.ReadConfInfo



An error occurred at line: 5 in the jsp file: /test/testfile.jsp
