I am trying to use the encodeURL method in a jsp to encode a URL with \"%\" symbol.

In your example, you can use the c:url and c:param tags:

In particular, the c:param tag will url-encode the value attribute. I just ran into a situation where I needed to generate a URL with a querystring containing a value that started with a pound sign. Without url-encoding, the pound sign was interpreted by the browser as the start of the anchor portion. I added the c:param tag, and the pound sign was encoded, allowing expected behavior when following the link.
