嵌入在HTML中的JAVA Applet在操作过程中挂起

标签： java web-services applet jax-ws

我在一台计算机上运行了一个Web服务，我想通过Applet访问该Web服务。独立的Applet可以完美运行，没有打嗝。但是当我将该applet嵌入到html文件中时，真正的问题就开始了。由于一些客户端限制，我需要将applet嵌入到Html文件中。当我打开html页面但不访问Web服务时，applet会启动。

我知道必须对Applet进行签名，以便它可以访问所有可用的资源。我已经签了Jar但它仍然挂起。为了解决这个问题，我想到了监控从客户端到运行Web服务的服务器的网络流量。我发现了一些差异......

当我运行独立的JAVA Applet（JAR文件）时：它调用确切的Web服务链接并获取响应。另一个最重要的事情是，它调用javaw.exe和完美的POST请求（第3个请求如下所示）。

当我运行嵌入在HTML文件中的相同applet时：我得到明显的结果，其中它调用java.exe并调用Get与Web服务的不正确链接（指向serviceexception.class而不是POST / LEDLabServer / services / Blink）< / p>

PS：我正在使用JAXRPC进行Web服务。

有人可以帮我吗？

答案 0 :(得分：1)

问题在您的日志中非常明显：

HTTP：响应，HTTP / 1.1，状态：未找到，URL：/LEDLabServer/sampleBlinkProxy/javax/xml/rpc/ServiceException.class

您没有在正确的位置安装类文件，因此浏览器无法找到它们。
