I’ve been wanting to add a custom User-Agent to groovyblogs.org for a while, so you know from your logs when I’m coming by to poll. It’s not easy to find sample code on this one, but the API does cover it just fine: def client = new HttpClient() def clientParams = client.getParams() clientParams.setParameter( org.apache.commons.httpclient.params.HttpClientParams.USER_AGENT, “GroovyBlogs/1.0 (http://www.groovyblogs.org)”) If you need to enable your client for proxy support too, you’ll need to add a couple of more [...]

I’ve always wanted to have a tinker with WebDAV, but never really had a good excuse to have a look at it. Since I’ve had to get up to speed with Maven, I’ve finally had a reason to get a WebDAV server happening locally for a few developers to share a repository. Turns out that running a WebDAV server on Glassfish (or whatever app server you like) is a snack thanks to the good folk [...]
