*更新*
刚刚意识到我有 RequestBuilder.PUT 而不是 RequestBuilder.GET ...现在更改该行会给我一个 404 Not Found 错误。这是萤火虫输出：

我猜我有一些路径设置不正确......我确实注意到在“GET”旁边的萤火虫输出中，路径中有一个双/......这可能是问题吗？这个双重/来自哪里？
感谢您的任何意见！

我创建了一个应该将字符串插入网页的 guice servlet。这是一个非常简单的 servlet。使用 RequestBuilder 调用 servlet 时出现 403 Forbidden 错误。
这是我的 Firebug 输出：
