Question

I’m a php guy, but I have to do some small project in JSP. I’m wondering if there’s an equivalent to htmlentities function (of php) in JSP.

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 unicode system                     sb.append('&#');                     sb.append(new Integer(ci).toString());                     sb.append(';');                     }                 }             }         }     return sb.toString(); }
