当我以Web应用程序的形式运行应用程序时出错，但当我以Java应用程序的形式运行时，该文件工作正常。。 让我再详细解释一下 下面是当我作为Java应用程序运行时，它工作得非常完美的代码

 package com.gst.user.dao.impl;
import java.sql.CallableStatement;
import java.sql.DriverManager;
import java.sql.Connection;
import java.sql.ResultSet;
import java.sql.SQLException;

public class Sqldbconnect {

    public static void main(String[] argv) throws SQLException {

        System.out.println("-------- SQL JDBC Connection Testing ------");

        try {

            Class.forName("com.microsoft.sqlserver.jdbc.SQLServerDriver");

        } catch (ClassNotFoundException e) {

            System.out.println("Where is your mysql jdbc Driver?");
            e.printStackTrace();
            return;

        }

        System.out.println("Mysql JDBC Driver Registered!");

        Connection connection = null;

        try {

            connection = DriverManager.getConnection(
                    "jdbc:sqlserver://Idatabase:65535;DatabaseName=Data_Base", "DUser","DPass");

        } catch (SQLException e) {

            System.out.println("Connection Failed! Check output console");
            e.printStackTrace();
            return;

        }

        if (connection != null) {
            System.out.println("You made it!");
            connection.close();
        } else {
            System.out.println("Failed to make connection!");
        }
    }

}
但是，如果我尝试作为web应用程序运行，它会抛出异常，这几乎是相同的事情，并且在同一个包中。。 这是代码

package com.gst.user.dao.impl;

import java.sql.CallableStatement;
import java.sql.Connection;
import java.sql.DriverManager;
import java.sql.ResultSet;
import java.sql.SQLException;

import com.gst.user.dao.CallSPDao;

public class CallSPDaoImpl implements CallSPDao {

    @Override
    public void callSPDao() throws SQLException {
        // TODO Auto-generated method stub
        System.out.println("Calling Stored processor Begins");

        System.out.println("-------- SQL JDBC Connection Testing ------");

        try {

            Class.forName("com.microsoft.sqlserver.jdbc.SQLServerDriver");

        } catch (ClassNotFoundException e) {

            System.out.println("Where is your mysql jdbc Driver?");
            e.printStackTrace();
            return;

        }

        System.out.println("Mysql JDBC Driver Registered!");

        Connection connection = null;

        try {

            connection = DriverManager.getConnection(
                    "jdbc:sqlserver://Idatabase:65535;DatabaseName=Data_Base", "DUser","DPass");
                //  
        } catch (SQLException e) {

            System.out.println("Connection Failed! Check output console");
            e.printStackTrace();
            return;

        }

        if (connection != null) {
            System.out.println("You made it!");
            connection.close();
        } else {
            System.out.println("Failed to make connection!");
        }
    }


    }
例外情况是：

SQLSERVER正在接受TCP/IP连接。。 我正在使用GAE1.7.2、JDK1.6.029，在Windowsx64上构建JAVA应用程序。 你知道如何解决这个问题吗？我认为防火墙不是问题

任何帮助/想法都将不胜感激。

您是否试图通过Google App Engine web应用程序与本地网络上的SQL Server取得联系

首先，是否在DNS中解析
Idatabase
或
IL93SQLF031
（提示：我希望不是），如果是，SQL服务器是否直接或通过NAT暴露于Internet（提示：同样，可能不是）

编辑：如果您打算在GAE上运行应用程序，您可能应该阅读

干杯，

由于应用程序使用的java.policy，您的应用程序没有打开套接字连接的权限。我没有使用GAE的经验，但我认为有一些限制，这可能是其中之一

看 和

由于Appengine的策略，您无法打开套接字。例如，您可能不使用文件系统。Google列出了所有您可能不做的事情，以及您可能使用的白名单类和包（标准Java包之外）。如果你试图超越极限，你会得到这个例外。 因此，当您将其作为Java应用程序运行时，它在逻辑上是有效的，因为在这种情况下，您的编译器不会经过Appengine（和GWT）验证。
因此，对于您的项目，请记住Appengine实例无法打开套接字，因此您无法使用自己的SQL server。你必须使用谷歌云SQL。appengine实例从“云外部”获取数据的唯一方法是URL Fetch API，它可以从appengine外部获取内容。

是的，这是我的本地网络，我正在尝试从Gae连接SQL Server。您需要向世界公开SQL Server，可能是通过路由器中的NAT或VPN/SSH隧道。另请参阅我对答案的编辑。我稍后将使用隧道，但目前我如何能够作为Java应用程序而不是web应用程序访问它？：：这可能是正确的，因为我无法读取文件，现在的问题是如何摆脱它。。有标准的例子吗？
