Problem with servlet getParameter()

[Viv Singh]

Hi,

I have a form that is submitted using the POST method.

In my servlet I get the values using the getParameter() method. I am having a problem with "escape" characters. Whenever, I enter e.g. an expression like Exp\s*Test in a field what I receive in the servlet is Exps*Test. Basically it "cuts out" the "\" from the expression. Is there a way of getting the full entered expression?

thanks.

A google search for "java escaped characters" found this discussion and a bunch more.

It looks like you may have to do some JavaScript processing of that text field before submitting the form.

You posted more information on how you are constructing the form in your (now closed) cross-post (please don't do that).

It looks as if you are using out.println() in a JSP to emit HTML. Why? That's really backwards. Aside from using old-fashioned scriptlets in a JSP in the first place (explore JSTL and EL), using Java strings to build HTML is fraught with problems.

Or is that code in a Servlet? If so, why are you not using a JSP to format the HTML?

You'll need to give us more details before we can proceed. You should not need to do any special processing of the string -- the form submission will properly encode it.

Use Filters for this where you can do somthing with request and response .

There is no need for any filtering to get proper encoding.
