Problem with replaceAll

[Gaurav]

Hi all,
I am having a problem with the replaceAll(str1,str2) method in java.
I am actually taking a substring from a user input, parsing it and then
I am doing:
userInput = userInput.replaceAll(str1,str2)
where str1 = some substring from user input
str2 = return value from someFunction(str1)

This works fine when user input does not contain parenthesis or any
other java.util.regex special characters. My code stops working in
case of regex special characters and I get str1 as the output of
replaceAll.
TIA
Gaurav

There are both regex and vanilla methods for doing replaces. They are
not named appropriately in my opinion. See
http://mindprod.com/jgloss/string.html#REPLACE to sort them out.

If you want to use regexes, see
http://mindprod.com/jgloss/regex.html#QUOTING.
