我正在使用一个返回数据源的方法。该方法如下所示：

public static DataSource getDataSource(){
        String url;
        //url="jdbc:hsqldb:file:"+filePath;
        url = "jdbc:hsqldb:file:D:/EclipseWorskpace/ew-pg/lmexadapter/hsqldb-example/src/main/webapp/WEB-INF/data/db/hsqldb.jar";
        BasicDataSource basicDataSource = new BasicDataSource();
        basicDataSource.setUsername("SA");
        basicDataSource.setPassword("password");
        basicDataSource.setDriverClassName("org.hsqldb.jdbc.JDBCDriver");
        basicDataSource.setUrl(url);
        System.out.println("$$$$$$$$ URL is : " + url);
        return basicDataSource;
    }

我从dao调用这些方法，并使用ibatis进行ORMap。当我通过junit测试运行我的测试用例时，它给了我一个异常：
