how to replace special characters in a String

Hi guys

I have a while loop in which I am trying to replace "${"+key+"}" with a value in a String. But somehow it throws a parsing exception. Would anyone know if there is another way to replace special characters from a String.

while(enum.hasMoreElements())
            {
                  String key = (String)enum.nextElement();
                  String value = (String)hshParams.get(key);
                  strSearch = strSearch.replaceAll("${"+key+"}", value);
            }

Anyhelp will be greatly appreciated

Try

strSearch = strSearch.replaceAll("\\$\\{"+key+"\\}", value);

$ { and } have special significance in a regex string. So you need to escape them.
You're also going to have problems if your key or value contain any special characters

be easier (and a lot more powerful) to use a templating library.
