我已经将JAR复制到了src\main\webapp\WEB-INF\lib.
我用eclipse.如果我将jar一个一个地添加到Project-> Java Build Path-> Add jars,然后我执行Project-> Maven-> Update Project Configuration,它们将被Maven删除.Eclipse显示错误,其中包含"xxx无法解析".

Env:
Eclipse Java EE IDE for Web Developers.
Version: Indigo Service Release 1
Build id: 20110916-0149

这是我的训练数据:

@relation hamspam

@attribute text string
@attribute class {spam,ham}

@data
'good',ham
'good',ham
'very good',ham
'bad',spam
'very bad',spam
'very bad, very bad',spam
'good good bad',ham

这是我的testing_data:

@relation test

@attribute text string
@attribute class {spam,ham}

'good bad very bad',?
'good bad very bad',?
'good',?
'good very good',?
'bad',?
'very good',?
'very very good',?

这是我的代码:

public static void NaiveBayes(String training_file, String testing_file) throws FileNotFoundException, IOException, Exception{
         //filter
        StringToWordVector filter = new StringToWordVector();

        Classifier naive = new NaiveBayes();

        //training data
