我试图连接到SQL Serverusing JDBC在一个Android应用程序。我进口sqljdbc4.jar到我的应用程序，但是当我到了

I'm trying to connect to SQL Serverusing JDBC in an android app. I imported sqljdbc4.jar into my application but when i get to

康恩=的DriverManager.getConnection（CONNSTRING）;

conn = DriverManager.getConnection(connString);

我得到以下错误：连接字符串

i get the error below: the connection string is

JDBC：SQLSERVER：//xxx.xxx.xxx.xxx：1433;加密= FASLE;用户=用户名;密码=密码;

jdbc:sqlserver://xxx.xxx.xxx.xxx:1433;encrypt=fasle;user=username;password=password;

任何一个可以告诉我是怎么回事了？ 如果我把同样的code到一个普通的Java应用程序运行良好。

Can any one tell me what is going wrong? If i put the same code into a regular java application it runs fine.

基本的Java

public class Test {
    public void dbConnect(String db_connect_string, String db_userid,
            String db_password) {
        try {

            Class.forName("com.microsoft.sqlserver.jdbc.SQLServerDriver");
            Connection conn = DriverManager.getConnection(db_connect_string,
                    db_userid, db_password);
            System.out.println("connected");
            Statement statement = conn.createStatement();
            String queryString = "select * from sysobjects where type='u'";
            ResultSet rs = statement.executeQuery(queryString);
            while (rs.next()) {
                System.out.println(rs.getString(1));
            }
        } catch (Exception e) {
            e.printStackTrace();
        }
    }

    public static void main(String[] args) {
        Test connServer = new Test();
        connServer.dbConnect("jdbc:sqlserver://Serverlocalip:1433", "sa",
                "sqlserver");
    }
}

的Andr​​oid code：

public List<String> dbConnect(String Host, String Port, String db_userid,
            String db_password) {
        List<String> Db_list = new ArrayList<String>();
        try {
            // String ConnectionString = "jdbc:sqlserver://" + Host + ":" +
            // Port;
            Class.forName("com.microsoft.sqlserver.jdbc.SQLServerDriver");
            Connection conn = DriverManager.getConnection(
                    "jdbc:sqlserver://Serverlocalip:1433", db_userid,
                    db_password);
            System.out.println("connected");
            Statement statement = conn.createStatement();
            String queryString = "select * from sysobjects where type='u'";
            ResultSet rs = statement.executeQuery(queryString);
            while (rs.next()) {
                System.out.println(rs.getString(1));
                Db_list.add(rs.getString(1));
            }
        } catch (Exception e) {
            Db_list.add("Error");
            e.printStackTrace();
        }
        return Db_list;
    }

any help would be great and Thanks in advance

推荐答案

更改名称的dirver和进口前的lib文件的 JTDS 1.3.0.jar 的$ C $下面file.and变动c它会正常工作.............

Change the Dirver Name and before import the lib file jtds 1.3.0.jar file.and change below the code it will work fine.............

public List<String> dbConnect(String Host, String Port, String db_userid,
                String db_password) {
            List<String> Db_list = new ArrayList<String>();
            try {
                String ConnectionString = "jdbc:jtds:sqlserver://" + Host + ":"
                        + Port;
                // Class.forName("com.microsoft.sqlserver.jdbc.SQLServerDriver");
                Class.forName("net.sourceforge.jtds.jdbc.Driver").newInstance();
                Connection conn = DriverManager.getConnection(ConnectionString,
                        db_userid, db_password);
                System.out.println("connected");
                Statement statement = conn.createStatement();
                String queryString = "select name from sys.databases";
                ResultSet rs = statement.executeQuery(queryString);
                while (rs.next()) {
                    Db_list.add(rs.getString(1));
                }
            } catch (Exception e) {
                Db_list.add("Error");
                e.printStackTrace();
            }
            return Db_list;
        }
