Hi,
Service providers appreciate if clients are telling who they are and a common
way for doing this is to add User-Agent parameter to http headers. Java is
setting this to something like "User-Agent= Java/1.6.0_43" if user agent is not
set elsewhere. This is not very useful information for service providers.
There seems to be at least three ways for setting user agent in Java.
- use jre start option
-Dhttp.agent="OpenJUMP"
- use setRequestProperty
URLConnection conn = url.openConnection();
conn.setRequestProperty("User-Agent", "OpenJUMP YOURS Client");
- use System.setProperty ("http.agent", "OpenJUMP GIS");
I do not know how and where the System.setProperty is supposed to be used but I
tested the two other alternatives. Adding -Dhttp.agent="OpenJUMP" into makes
OpenJUMP to use header "User-Agent: OpenJUMP Java/1.6.0_43". Using
setRequestProperty("User-Agent", "OpenJUMP YOURS Client") turns header into
exactly " User-Agent: OpenJUMP YOURS Client".
I would suggest three things:
- Add http.agent into WMS connection in around line 117 in the file
http://jump-pilot.svn.sourceforge.net/viewvc/jump-pilot/core/trunk/src/com/vividsolutions/wms/WMService.java?revision=3459&view=markup
I woud suggest to use "con.setRequestProperty("User-Agent", "OpenJUMP WMS
Client");
- Add jre start option -Dhttp.agent="OpenJUMP" into the starting scripts. This
makes for example ad hoc BeanShell scripts to advertise OpenJUMP as user agent
if nothing else is set in the code.
- Write somewhere into developer documents an advice to use an informative user
agent if new plugins or scripts are communicating with some services through
http.
What do the real OJ developers think?
