Receive javascript array in java servlet

Question

I am looking for a way to send an array from my jsp file to java servlet.

Currently I have this

              var members = [];
              var table = document.getElementById("my_table");
                    for(var i = 1; i < table.rows.length; i++) {
                            if(table.rows[i].getAttribute("checked")==="true") {
                                members.push(table.rows[i].id.substring(2));
                            }
                    }
                    console.log(members);
          }

I want to send my members array to my servlet. The problem is that I think servlet only lets me get strings request.getParameter("my_value");

So how can I do this?

you can send the array like this:

http://localhost:8080/myApp/myServlet/?members=mem1&members=mem2&members=mem3

and in the servelt:

String[] arrMembers = request.getParameterValues('members');
// arrMembers = ["mem1","mem2", "mem3"]
