Hi Paul,
Depending on how you have the servlet configured I would embed this
into the Servlet URL instead. (that way your API is kind of
protected).
Use the Constants interface to load the Version from a properties
file.
-== foo/package/ClientConfiguration.properties ==-
version=1.0
-== declare the interface ==-
interface foo.package.ClientConfiguration extends Constants {
@DefaultStringValue("99.9999")
String version();
}
-== servlet declaration ==-
<servlet-mapping>
<servlet-name>MyRPCService</servlet-name>
<url-pattern>
/foo.package.Something/service/*
</url-pattern>
</servlet-mapping>
-== usage ==-
ClientConfiguration clientConfig = (ClientConfiguration )
GWT.create(ClientConfiguration .class);
endpoint.setServiceEntryPoint(GWT.getModuleBaseURL() + "service/" +
clientConfig.version());
{{ and then in the servlet you can look for the version }}
better still would be to subclass your servlet version differences,
and actually map the right servlet to the right version URL etc etc.
Just a thought...
