How i can get a array in the current page?

Question

Can i send a array parameters from previous page to current page?
the coding like below:
// the coding in the previous page
String[] strSend = {"a", "b", "c"};
HashMap map = new HashMap(2);
map.put("array", strSend);
pageContext.setForwardURL(
"OA.jsp?OAFunc=XXFMSRHISQF",
null,
KEEP_MENU_CONTEXT,
null,
map,
true,
ADD_BREAD_CRUMB_NO,
IGNORE_MESSAGES );
//the coding in the processRequest of the current pageCO.
String strParam = pageContext.getParameter("array");
the problem is that the type of "strParam" is a String.
it's not a array of String. So it is not the parameter what i need.
can u tell me how to get the array parameter from previous page. thanks.

Answer 1

This cannot be achieved directly while using the setForwardURL method, all values that are there in the Hashmap will be appended when the redirection is done, so you cannot get the values that are there in the array object directly.
Workaround that I can think of, put all the array values in a String object, appended by a delimiter, in the second page, after you do a getParameter(String), recover the values using a StringTokenizer and the delimiter that you used while appending the string values and store the values in a Array.
