public static String[] splitQuotedString(String input,
                                         String pattern)

splitQuotedString

public static String[] splitQuotedString(String input,

                                         String pattern)

This method splits a possible quoted String into tokens, respecting the quotations. The returned array of strings does not contain the limiting quotations.

input - A string, possibly containing quotes.

Returns:

An array of strings which are tokens from the splitted input-string.

parseQueryString

public static Hashtable<String,String> parseQueryString(String qs)

Parameters:

qs - The query-string that will be parsed.

public static String extractFormData(String contentType,
                                     String content)
