[英]Getting 404 error on running Restful web Service in java
我試圖在Java中創建一個寧靜的Web服務。 每當我嘗試運行它時,我都會收到404錯誤,並且我無法弄清原因!
我指的是JavaTPoint 。
這就是我的項目的樣子-

@GET
@Path("/txt")
@Produces(MediaType.TEXT_XML)

String response = null;
response = "<?xml version='1.0'?><hello>Hello xml</hello>";
return response;
}
}

我正在關注回應-
任何人都可以指出我在這里做錯了嗎?任何幫助將不勝感激。
您需要指定api的完整路徑
<a href="[full path to your servlet container]/rest/files/txt">Download Text File</a>
