hi Dan, thanks for asking

I did this in the end..

// function cleantext(string) {

// string = "" & string;

// string = Replace(string, chr(13) & chr(10) & chr(13) & chr(10), "", "all");

// string = Replace(string, chr(13) & chr(10), " ", "all");

// string = string & "";

// return string;

// }

Although actually I also ended up changing my charset of my tables to utf8 (it was latin_swedish) and that seems to have solved the head issue (with special characters (bullet points i think it was) throwing an error when inserting them in the db)

Did you have any joy with this?

It is unnecessary to convert it to CFML code. There is in fact every advantage in running the Java code directly. Reuse saves you time, and you avoid errors.

Save the above content as HtmlEscape.java. Compile it to HtmlEscape.class, using the same Java version as that of your Coldfusion installation. Create the directory /net/htmlescape/ in {CF_WEBROOT}\WEB-INF\classes and copy the class file into it. Restart Coldfusion.

You can now use the HtmlEscape service. For example, start with the following test code:

Hi - Following on from a recent post about how to strip our special characters from a string before insertion to the db I have found this Java code - my question is, how can I turn this into something I can use with CF? I think I need to use the cfscipt tag but that's right on the boundaries of my knowledge base.. If anyone could please help I'd be ever so grateful - thank you!
