I have tested it ,it works fine,there must be something wrong with your code. Following is my test code


   HttpClient client = new HttpClient();
      client.getState().setCredentials(
            new AuthScope("localhost", 8080, "Alfresco"),
            new UsernamePasswordCredentials("admin", "admin"));

      String apiurl = "http://localhost:8080/alfresco/service/api/tags/workspace/SpacesStore/tag1";
      DeleteMethod delete = new DeleteMethod(apiurl);
      try {
         delete.setDoAuthentication(true);
         int status = client.executeMethod(delete);
         if (status != HttpStatus.SC_OK) {
            System.err.println("Method failed: " + delete.getStatusLine());
         }
         String resultString = delete.getResponseBodyAsString();
         System.out.println(resultString);
      } catch (Exception e) {
         e.printStackTrace();
      } finally {
         delete.releaseConnection();
      }

Thanks, kaynezhang!!!

But I have the same error… I`ve test your code and the server throw the following exception: http code: 405 Method not allowed.

Could it be for the permits of user?. I have admin permission but I am not de administrator or creator of Alfresco repository…

Which version of afresco are you using? it might be a bug.
I don't think it is a permission problem,but yuou can give it a try and test it with admin user account
