Our portal runs behind a firewall. In order to access the web services from the internet, we set the -Dhppd.proxyHost=[proxy] and -Dhttp.proxyPort=[proxy_port] in the JAVA_OPTS, and it works for 2.2.x. When we test JBP 2.4 + AS 4.0.4GA + JBossWS 1.0.2GA, it does not work anymore. Any ideas why? Here is the exception stack using the news portlet. 10:04:29,561 ERROR [NewsPortlet] Fatal Error reading/parsing XML Source. java.io.IOException: Server returned HTTP response code: 504 for URL: http://jboss.org/jbossBlog/blog/?flavor=rss2 at sun.net.www.protocol.http.HttpURLConnection.getInputStream(HttpURLConnection.java:1133) at java.net.URL.openStream(URL.java:1007) at org.jboss.samples.portlet.news.NewsPortlet.doView(NewsPortlet.java:143) at javax.portlet.GenericPortlet.doDispatch(GenericPortlet.java:167) at javax.portlet.GenericPortlet.render(GenericPortlet.java:407) Some thing happens for the weather portlet.
