I've come up against a problem. I'm using example 14 - Integrating
with JSTL on the <google:maps> JSP tag library page
(http://www.lamatek.com/GoogleMaps/example_14.jsp). The example uses
address information to locate the nodes on the map. This means that
strings are provided. However for my project I need to use coordinates
to locate nodes on the map. The requirement here is that the
coordinates must be of type double. How can I convert the value I'm
getting from the database to a double. Here is my jsp at the moment:
I'm getting a number format exception as the googlemaps
oint tag is
expecting a double value for latitude and longitude. How can I convert
the type so this error will not occur? I've checked on the web and
found lots of stuff on formatting variables but I can't seem to get
anything to work.
Thanks in advance.
