Use regular expression. See this sample;

    String patternStr = "\\s+";
    String inputStr = "Richard hailes";
    Pattern pattern = Pattern.compile(patternStr);
    Matcher matcher = pattern.matcher(inputStr);
    if(matcher.find()) {
       System.out.println("Found");
     } else {
       System.out.println("Not Found");
     }

public static boolean isBlank(String str) { int strLen; if (str == null || (strLen = str.length()) == 0) { return true;} for (int i = 0; i < strLen; i++) { if ((Character.isWhitespace(str.charAt(i)) == false)) {return false;}}return true;} }

use indexOf function. 

if(name.indexOf(' ') >= 0){
   // name have space
}

<c:if test="${fn:contains(name, ' ')}">
  It contains a space
</c:if>

See https://stackoverflow.com/tags/jstl/info for info about the JSTL.

You can look at this page which describes how to use the contains function in JSP. You can use that to see if the string contains " ".
