Question

当我尝试通过Java访问外部Web服务时，我收到了连接超时错误。

我做的步骤：

从https.somesite.com/ws/ws我单击安装证书安装证书。然后我将证书导出到cert.cer文件。并做了以下，

keytool -import -keystore cacerts -file openrating.cer -alias somesite.com
keytool -list -keystore cacerts -alias somesite.com
keytool -delete -keystore cacerts -alias somesite.com

以下是我的java代码。

HttpClient httpclient = new HttpClient();

System.setProperty("security.provider.n","com.sun.net.ssl.internal.ssl.Provider");
System.setProperty("java.protocol.handler.pkgs","com.sun.net.ssl.internal.www.protocol");
System.setProperty("javax.net.ssl.keyStore", "C:\\j2sdk1.4.2_06\\jre\\lib\\security\\cacerts");
System.setProperty("javax.net.ssl.keyStorePassword", "changeit");
System.setProperty("javax.net.ssl.trustStore", "C:\\j2sdk1.4.2_06\\jre\\lib\\security\\cacerts");
System.setProperty("javax.net.ssl.trustStorePassword", "changeit");


GetMethod httpget = new GetMethod(xlatePage);
httpget = new GetMethod("https://somesite.com/ws/ws/?siccode=10000000&xwalk=8");
httpget.setQueryString(sicList);
try { 
    try {
        httpclient.executeMethod(httpget);
    } catch (HttpException e) {
        e.printStackTrace();
    } catch (IOException e) {
        e.printStackTrace();
    }

以下是我的例外情况。

即使使用System.setproperty方法添加代理主机和端口也无济于事。

PS：当我点击浏览器中的Web服务URL时，我得到了正确的响应。

如果我错过了什么，请指导我。
