Something wrong with you context path. 你的上下文路径有问题。 According to form you submitting, try this: 根据您提交的表单，试试这个：

<FORM ACTION="${pageContext.request.contextPath}/validate">

Compare this two urls : 比较这两个网址：

http://localhost:9080/LaunchingGateway_Maintance/services/Test

and 和

http://localhost:9080/validate

So looks like you are missing some context path LaunchingGateway_Maintance 所以看起来你错过了一些上下文路径LaunchingGateway_Maintance
