在Tomcat中使用Servlet部署GWT .war [英] Deploy GWT .war with Servlet in Tomcat

问题描述

我一直在遵循有关构建示例GWT应用程序的教程: http://code.google.com/webtoolkit/doc/latest/tutorial/gettingstarted.html

I've been following the tutorial on building a sample GWT Application: http://code.google.com/webtoolkit/doc/latest/tutorial/gettingstarted.html

然后我想根据本教程尝试公开一个servlet，以提供一些JSON数据: http://code.google.com/webtoolkit/doc/latest/tutorial/JSON.html

I then wanted to try exposing a servlet for serving up some JSON data according to this tutorial: http://code.google.com/webtoolkit/doc/latest/tutorial/JSON.html

两个教程都很清晰，我也没有任何问题可以使其在以开发模式运行的Eclipse中工作.我测试它的方法是转到以下URL: http://localhost:8888 /stockwatcher/stockPrices?q = ABC + DEF 会按照本教程的设计返回json结果.但是现在我想将该项目作为war文件部署并在我自己的Tomcat服务器中运行.我发现了本教程，用于部署将项目转换为.war文件:

Both tutorials are very clear and I had no issues getting it to work in Eclipse running in development mode. The way I'm testing it is by going to this URL: http://localhost:8888/stockwatcher/stockPrices?q=ABC+DEF That returns json results just as is designed in the tutorial. But now I want to deploy this project as a war file and run it in my own Tomcat server. I found this tutorial for deploying turning the project into a .war file: http://blog.elitecoderz.net/gwt-and-tomcat-create-war-using-eclipse-to-deploy-war-on-tomcat/2009/12/. It was clear, and the .war file built without any errors, but after I deploy it, my servlet for JSON data does not work. I simply get a 404 page and nothing happens. I also don't see anything in the server.log. Also, I am attempting to deploy this in Tomcat 6, if that makes any difference.

推荐答案

我知道了；这是我的web.xml文件中的url-pattern标记出现的问题.

I figured it out; it was a problem with the url-pattern tag in my web.xml file.

这就是我所拥有的:

<url-pattern>/stockwatcher/stockPrices</url-pattern>

，但这导致可从以下URL访问stockPrices servlet: http://127.0.0.1:8080/stockwatcher/stockwatcher/stockPrices?q=ABC

but this resulted in the stockPrices servlet being accessible from this URL: http://127.0.0.1:8080/stockwatcher/stockwatcher/stockPrices?q=ABC

相反，我将其更改为:

<url-pattern>/stockPrices</url-pattern>

因为它已经在StockWatcher战争环境中了.

Because it's already within the stockwatcher war context.

现在此链接可以正常使用: http://127.0.0.1:8080/stockwatcher /stockPrices?q = ABC

Now this link works as expected: http://127.0.0.1:8080/stockwatcher/stockPrices?q=ABC
