This servlet lets you transparently pass all the incoming requests to the Google static Maps service. Servlet simply performs a role of HTTP proxy for your requests. The Google Static Maps API lets you embed a Google Maps image on your web page without requiring JavaScript or any dynamic page loading. The Google Static Map service creates your map based on URL parameters sent through a standard HTTP request and returns the map as an image you can display on your web page. Why you might need this proxy? It is actually a cache for the maps. Also - there is one interesting usage (e.g. it is used in our Places for Facebook mashup). Strange, but you cannot post Google Static Maps to Facebook. Results are strange - sometimes it works, sometimes - does not. This proxy lets you include Google Static Maps from your site. How to use proxy servlet: a) download staticMapPackage.jar and save it in WEB-INF/lib b) describe this servlet in web.xml file. Servlet accepts the following initial parameters:
<servlet> <servlet-name>StaticMap</servlet-name> <servlet-class>com.jsos.staticmap.StaticMapProxyServlet</servlet-class> </servlet> c) describe a mapping for this servlet in web.xml file. E.g.:
<servlet-mapping> <servlet-name>staticMap</servlet-name> <url-pattern>/servlet/staticmap</url-pattern> </servlet-mapping> and now you can request static map by this way:
http://your_host/servlet/staticmap?center=55.78808,37.55019&zoom=13&size=90x90 &sensor=false
Also you can describe the proxy settings for the servlet itself.
Parameters are proxyHost and proxyPort. E.g.:
<servlet> <servlet-name>StaticMap</servlet-name> <servlet-class>com.jsos.staticmap.StaticMapProxyServlet</servlet-class> <init-param> <param-name>proxyHost</param-name> <param-value>10.114.7.95</param-value> </init-param> <init-param> <param-name>proxyPort</param-name> <param-value>80</param-value> </init-param> </servlet> For downloading: Static Map proxy package: staticMapPackage.jar
