How to pass Array of string from action class to jsp page

this is my action class

package login.ipm;

import java.sql.*; import java.util.ArrayList; import javax.servlet.http.HttpServletRequest; import javax.servlet.http.HttpServletResponse; import javax.servlet.http.HttpSession; import org.apache.struts.action.ActionForm; import org.apache.struts.action.ActionForward; import org.apache.struts.action.ActionMapping;

/** * * @author Gopi Daggumalle */ public class DiagservicesAction extends org.apache.struts.action.Action {

private static final String SUCCESS = "success";

@Override
public ActionForward execute(ActionMapping mapping, ActionForm form,
        HttpServletRequest request, HttpServletResponse response)
        throws Exception 
{
    int count=0;
Connection con=null;
ResultSet rs;
Statement st;
    HttpSession session=request.getSession(true);
    DiagservicesForm lf=(DiagservicesForm) form;
    String pname=lf.getPname();
    String ref=lf.getRef();
    String tno=lf.getTno();
    String cbox=lf.getCbox();
    int age=lf.getAge();
    String sex=lf.getSex();
    String cost=lf.getCost();
    String counter=lf.getCounter();
    String vno=lf.getVno();
    String amt=lf.getAmt();
    String[] check =request.getParameterValues("cbox");
    int a=check.length;
    //request.setAttribute("check", a);


    String testname[]=new String[200];
String testcode[]=new String[200];
String dept[]=new String[200];
String cost1[]=new String[200];
String counter1[]=new String[200];

   /* if (check != null)

{ for (int i = 0; i < check.length; i++) { System.out.println (check[i]); } } else System.out.println ("none"); */ try { ArrayList UserList1=new ArrayList(); for(int i=0;i

        st = con.createStatement();
        rs = st.executeQuery("SELECT * FROM user_charges WHERE TEST_CODE="+tcode+" and service_code=1");
        //System.out.println("SELECT * FROM user_charges WHERE TEST_CODE="+tcode);
        while (rs.next())
        {
            dept[count] = rs.getString("department");
            testcode[count] = rs.getString("test_code");
            testname[count] = rs.getString("test_name");
            count++;

        }
    }

    }
    catch(Exception exception)
    {
        System.out.println(exception);
    }

    for (int i = 0; i < check.length; i++) 
  {
    System.out.println (testname[i]);
  }



    request.setAttribute("testname", testname);



    ArrayList print=new ArrayList();


     PrintDiagForm cf=new  PrintDiagForm();
     cf.setPname(pname);
     cf.setRef(ref);
     cf.setTno(tno);
     cf.setAge(age);
     cf.setSex(sex);
     cf.setCost(cost);
     cf.setCounter(counter);
     cf.setVno(vno);
     cf.setCbox(cbox);
     cf.setAmt(amt);




     print.add(cf);
     session.setAttribute("print",print);

    return mapping.findForward(SUCCESS);
}

}

my jsp page is

You can use session.setAttribute() and session.getAttribute() methods. In your action class,

String[] arr = {"A","B","C","D"};
for (int x = 0; x < arr .length; x++) {
out.println(arr[x]);
}
session.setAttribute("names", arr);

And through your jsp page, get array values.

<%
try {

String[] str = (String[]) session.getAttribute("names");

for (int x = 0; x < str.length; x++) {
out.println(str[x]);
}

} catch (Exception e) {
out.println(e);
}
%>
