JAVA-是否可以将接收到的servlet值传递给.java文件，但是在另一个项目中？

Question

good afternoon. I have a .JSP file that send a value to a servlet file. I have another project, where there is a java file in that i want to get this servlet value received by .JSP file.

My question is if is there possible pass this servlet value to this .java file in another project ? Or can i send by .JSP file directly ?

I created a Java Class in my Web Application, but now, how can i pass the servlet parameter to this java class ?

I will put the code down here:

Servlet code:

public class ServletJava extends HttpServlet {

    protected void processRequest(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException {
     response.setContentType("text/html;charset=UTF-8");

     /*I WANT TO INSTANCE THE PARAMETER HERE TO SEND TO OTHER CLASS*/
    }

    @Override
    protected void doGet(HttpServletRequest request, HttpServletResponse response)
            throws ServletException, IOException {
        processRequest(request, response);
    }

    @Override
    protected void doPost(HttpServletRequest request, HttpServletResponse response)
            throws ServletException, IOException {
        processRequest(request, response);
    }

    @Override
    public String getServletInfo() {
        return "Short description";
    }

}

The Class java:

public class RecebeServlet {
     public static void main(String[] args) throws Exception {
      /*I WANT RECEIVE THE PARAMETER HERE !! */
   }
}

Answer 1

It is probably bad practice to have a class with only one main mathod. I am sure that you can divide the logic from that class into several methods instead of having one giant main .

But anyway, since you asked: Just call your main method as you would call any static method:

String[] args = new String[1];
args[0] = yourValue;
RecebeServlet.main(args);

But again, please consider refactoring your RecebeServlet class. You do not want to have program logic in your main method.
