在 Apache 上使用 RPC 调用部署 GWT 应用程序

发布于 2024-12-20 07:38:09 字数 1688 浏览 2 评论 0 原文

我正在开发一个 GWT 应用程序，比如说连接到 Web 服务的 SoapCon，因此我在服务器端使用 Axis 来连接到此网络服务。当我在开发模式下运行我的应用程序时，它工作正常（返回 xml 作为其响应）。但是，当我将应用程序部署到 Linux 中的 Apache 2.0 时，RPC 失败并为 servlet 映射 URL 返回 404。

当我将此应用程序部署到 Apache 时，我递归地将 /war/soapcon 复制到 /var/www/html/SoapCon 目录以及 SoapCon.html 和 .css。

这是我的 web.xml：

<!-- Servlets -->
<servlet>
  <servlet-name>greetServlet</servlet-name>
  <servlet-class>com.sample.google.server.SampleServiceImpl</servlet-class>
</servlet>

<servlet-mapping>
  <servlet-name>greetServlet</servlet-name>
  <url-pattern>/soapcon/greet</url-pattern>
</servlet-mapping>

SoapCon.gwt.xml

<?xml version="1.0" encoding="UTF-8"?>
<module rename-to='soapcon'>
....

RPC 服务的客户端存根：

@RemoteServiceRelativePath("greet")
public interface SampleService extends RemoteService {
    String method( String params, ... );
}

当我运行我的应用程序时

http://localhost/SoapCon/SoapCon.html

模块已加载，但是当我单击将从服务器调用 RPC 方法的按钮时，会发生错误返回：

com.google.gwt.user.client.rpc.StatusCodeException: 404 <!DOCTYPE HTML PUBLIC "-//IETF//DTD HTML 2.0//EN">
<html><head>
  <title>404 Not Found</title>
</head><body>
<h1>Not Found</h1>
<p>The requested URL /SoapCon/soapcon/greet was not found on this server.</p>
</body></html>

我应该做什么？请帮忙。提前致谢。

I'm developing a GWT app, let's say SoapCon that connects to a web service so I'm using Axis on my server-side to connect to this web service. When I run my app in development mode, it works fine (which returns xml as its response). But when I deployed my app to Apache 2.0 in Linux, RPC failed and returns 404 for the servlet mapping URL.

When I deployed this app to Apache, I recursively copied the /war/soapcon to the /var/www/html/SoapCon directory and the SoapCon.html and .css.

Here's my web.xml:

<!-- Servlets -->
<servlet>
  <servlet-name>greetServlet</servlet-name>
  <servlet-class>com.sample.google.server.SampleServiceImpl</servlet-class>
</servlet>

<servlet-mapping>
  <servlet-name>greetServlet</servlet-name>
  <url-pattern>/soapcon/greet</url-pattern>
</servlet-mapping>

SoapCon.gwt.xml

<?xml version="1.0" encoding="UTF-8"?>
<module rename-to='soapcon'>
....

The client side stub for the RPC service:

@RemoteServiceRelativePath("greet")
public interface SampleService extends RemoteService {
    String method( String params, ... );
}

When I run my app

http://localhost/SoapCon/SoapCon.html

the module is loaded but when I clicked a button which will call RPC method from my server, error occurs returning:

com.google.gwt.user.client.rpc.StatusCodeException: 404 <!DOCTYPE HTML PUBLIC "-//IETF//DTD HTML 2.0//EN">
<html><head>
  <title>404 Not Found</title>
</head><body>
<h1>Not Found</h1>
<p>The requested URL /SoapCon/soapcon/greet was not found on this server.</p>
</body></html>

What should I do? please help. thanks in advance.
