如何用自己的电脑做服务器，用java语言写服务器程序

你指的服务器程序是指B/S(浏览器/服务器)

还是C/S(客户端/服务器)模式啊,不过不管你想写那种服务端程序首先都是要先安装JDK的,然后才开始开发,如果是B/S可以使用tomcat作为服务器,C/S的话就要自己写了

怎样让服务器执行已经在别的电脑上写好的代码（Java写的）？具体步骤是怎样的？

如果是源码.java文件，需要先编译成.class文件，编译用服务器上面的jdk版本编译

简单的java文件，javac就可以了，如果是一个项目就比较麻烦了

一般还是用eclipse自动编译最简单了，然后上传到服务器

如果是命令行运行的代码，找到入口类的main方法，然后执行 java xxx就行了 （xxx是入口类名）

HttpPost发送字符串到服务器，服务器接收代码并显示怎么写Java代码？

服务器端接收客户端的请求的话，需要在服务器端的java文件实现HttpServlet这个接口，并且在web.xml里配置一个客户端的请求拦截。

web.xml里的代码里添加

servlet

servlet-nametestServlet/servlet-name!--这个名字可以自己定--

servlet-classcom.sun.testServlet/servlet-class!--这里是你需要接收客户端请求的那个类以及包名，也就是下面拦截到的url会转发到的那个类--

/servlet

servlet-mapping

servlet-nametestServlet/servlet-name!--和上面的name需要一样--

url-pattern/*/url-pattern!--什么类型的客户端请求会被拦截，/* 就是全拦截了--

/servlet-mapping

然后再服务器端的类文件，要实现 HttpServlet这个接口。并把doGet()方法和doPost()方法重写。

这两种方法分别对应的是客户端的get请求和post请求的处理，你的是post请求的话，就在doPost()方法内，写你的业务。

然后再用下面两句话，设置你要返回客户端的数据。

//这是设置你要返回去的数据。value才是你的数据，key是标签。

request.setAttribute("key", "value");

//这是设置你要返回去test.jsp这张页面。

request.getRequestDispatcher("test.jsp").forward(request, response);

不知道你是不是这个意思，你可以再去看看相关servlet方面的知识，

关于客户端和服务器端大概也就是有个servlet作为请求的拦截

然后经过相关判断后，选择性的传到服务器的相应类里面。

再经过类里面的业务，把得到需要的数据回传到指定的页面上。

根据要求编写java代码，急求，答案正确加100分！求高手！

关于java，soap服务器端的代码怎么写

soapenv:Header/

soapenv:Body

api:getEmp

shopIdstring/shopId

/api:getEmp

/soapenv:Body

/soapenv:Envelope

这个时SOAP协议的标准报文格式，客户端只要发送这样的报文给支持SOAP协议的webservice服务器即可成功调用web service服务

服务端：部署服务只需要自己定义服务的接口和实现类，并用@webservice注解，通过endPoint类直接发布即可

做web服务器的一些简单的代码如何写？（用Java里面的面向对象的知识和sql的东西写）

用java写一个页向对像的web 服务器,得借助工具!

不然估计把你累吐血了!

想用java做一个web 服务器你得懂这样的几个方面!

xml,servlet,jsp,javabean用这些应该做一具小型的差不多了!

首先,jsp属性界面类,响应客户端的请求发送给servlet!

servlet控制类,sevlet接受客户端的请求做相应的处理!

比如,调用javabean的数据库连接的类!

做完一系列操作再由servlet转发到jsp，显示客户所需要的数据!
