    Not sure if this will work, but from what I've seen JSP is pretty similar to ASP... in ASP I'd do:

    Code:
    Function RemoveSpaces(str) ''''''''''''''''''''''
         If IsNull(str) Then str = ""
         Dim rsRegEx
         Set rsRegEx = New RegExp
         rsRegEx.Pattern = "\s"
         rsRegEx.Global = True
         RemoveSpaces = rsRegEx.Replace(str,"")
    End Function ''''''''''''''''''''''''''''''''''''
    
    myString = RemoveSpaces(myString)
    And in javascript it would be:

    Code:
    myString = myString.replace(/\s/g,'')
    Going by this page, I'd say it would be something like:

    Pattern p = Pattern.compile(" ");
    String toMatch = "he llo";
    Matcher m = p.matcher(toMatch);
    String replaced = m.replaceAll("");

    but don't quote me on that as I have never used JSP and don't have any method whatsoever to test it!
