如何从利用APP直接与Servlet通信？

直接序列化对象就可以了。

这是抄来的部分代码：

URL studentDBservlet = new URL( servletLocation );

URLConnection servletConnection = studentDBservlet.openConnection();

// Don't used a cached version of URL connection.

servletConnection.setUseCaches (false);

servletConnection.setDefaultUseCaches(false);

// Read the input from the servlet.

//

// The servlet will return a serialized vector containing

// student entries.

//

inputFromServlet = new ObjectInputStream(servletConnection.getInputStream());

studentVector = (Vector) inputFromServlet.readObject();

先试试看能不能实现。呵呵。
