How do I add query parameters to a GetMethod (using Java commons-httpclient)?

Post methods have post parameters, but get methods do not.

Query parameters are embedded in the URL. The current version of HttpClient accepts a string in the constructor. If you wanted to add the key, value pair above, you could use:

String url = "http://www.example.com/page?key=value";
GetMethod method = new GetMethod(url);

A good starting tutorial can be found on the Apache Jakarta Commons page.

Update: As suggested in the comment, NameValuePair works.

GetMethod method = new GetMethod("example.com/page"); 
method.setQueryString(new NameValuePair[] { 
    new NameValuePair("key", "value") 
});
