can you please help on this? Thanks in advance.....

Use the java.net.URLEncoder class to encode all of your parameter values.

Expanding on that..if the request came to you via a GET or POST, it should already be encoded.

Not necessarily.

If the data was from a form submission, then yes, the data is automatically encoded.

However, if a link with parameters was built in code (either client or server side), then the data needs to be properly encoded.

That also applies to Ajax requests.

If it is get method we can use encodeURIComponent("field name") in
java script
