htmlentities在JSP中是否等效？

public static String stringToHTMLString(String string) {    StringBuffer sb = new StringBuffer(string.length());    // true if last char was blank    boolean lastWasBlankChar = false;    int len = string.length();    char c;    for (int i = 0; i < len; i++)        {        c = string.charAt(i);        if (c == ' ') { // blank gets extra work, // this solves the problem you get if you replace all // blanks with &nbsp;, if you do that you loss  // word breaking if (lastWasBlankChar) {     lastWasBlankChar = false;     sb.append("&nbsp;");     } else {     lastWasBlankChar = true;     sb.append(' ');     } }        else { lastWasBlankChar = false; // // HTML Special Chars if (c == '"')     sb.append("&quot;"); else if (c == '&')     sb.append("&amp;"); else if (c == '<')     sb.append("&lt;"); else if (c == '>')     sb.append("&gt;"); else if (c == 'n')     // Handle newline     sb.append("&lt;br/&gt;"); else {     int ci = 0xffff & c;     if (ci < 160 )         // nothing special only 7 Bit         sb.append(c);     else {         // Not 7 Bit use the unipre system         sb.append("&#");         sb.append(new Integer(ci).toString());         sb.append(';');         }     } }        }    return sb.toString();}
