Java Eclipse SQL Server连接

Question

I am getting the following SQLServer exception after trying to establish connection: The server principal "SQLServer" is not able to access the database "TMO" under the current security context.

Here's my code:

public java.sql.ResultSet dbConnect(String db_connect_string,
        String db_userid,
        String db_password,
        String query)
  {
  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 = query;
     ResultSet rs = statement.executeQuery(queryString);
     /*while (rs.next()) {
        System.out.println(rs.getString(1));
     }*/
     return rs;
  } catch (Exception e) {
     e.printStackTrace();
     return null;
  }

and this is where I call this class:

String query = "select TOP 45000 MEMO_MANUAL_TXT,RAND() from TMO.dbo.merged_memo where       MEMO_MANUAL_TXT <> 'CCIH_NULL' and MEMO_MANUAL_TXT not like '%QuikView%' order by RAND()";
    ConnectMSSQLServer connServer = new ConnectMSSQLServer();
    java.sql.ResultSet m_ResultSet = connServer.dbConnect("jdbc:sqlserver://localhost", "SQLServer",
               "****", query);

I am using SQLServer 2008R2 on a Windows Server 2008 R2 OS machine

update your db_connect_string with below:

jdbc:sqlserver://localhost:<port>;instance=<sql_server_instance_name>;databaseName=<your_database_name>;integratedSecurity=false;

and where are you closing your database connection ?? I suggest you to add finally block and add the code to close the connection object.
