我有以下问题:

当我从项目加载资源时一切正常,但当我把它放在.jar上并尝试加载时我得到一个异常.

代码是:

InputStreamReader reader =
    new InputStreamReader(
        this.getClass().getResource(fileName).openStream())  
CsvReader stream = new CsvReader(reader);  
try {  
    while (stream.readRecord()) {  
        line = stream.getRawRecord();  
        //DO SOMETHING...  
    }  
}catch (Exception e) {  
    System.err.println(e.getMessage());  
    e.printStackTrace();  
} finally {  
    stream.close();  
}

而stackTrace是:

    Inflater has been closed java.lang.NullPointerException: Inflater has been closed

 at utils.csvreader.CsvReader.checkDataLength(CsvReader.java:1198)
 at utils.csvreader.CsvReader.readRecord(CsvReader.java:604)

问题发生了stream.getRawRecord().我也尝试使用BufferedReader,结果相同readLine();

有任何想法吗？
