RSS Portlet

If you want to access external sites through RSS channel, then you have to add your proxy server settings in the domain.xml/server.xml depending on whether your webcontainer is sun Appserver/ sun Webserver

Please add the following :

<jvm-options>-Dhttp.proxyHost=Proxy-Host</jvm-options>

<jvm-options>-Dhttp.proxyPort=Proxy-Port</jvm-options>

<jvm-options>-Dhttp.nonProxyHosts="Portalserver-host"</jvm-options>

you can edit one of the JSPs for the portlet, and add debugging in there to print out the JVM's system properties, such as:

<%

Properties p = System.getPropeties();

%>

Properties: <%=p%>

the portlet uses a standard URLConnection, so it should make use of the JVM proxy settings as described. you can see the interesting file here:

https://portlet-repository.dev.java.net/source/browse/portlet-repository/rsspor tlet/src/java/com/sun/portal/rssportlet/FeedHelper.java?rev=1.2&view=markup

take a look at the getFeed() method.

hi,

a little googling shows a reference to a JVM property "http.proxyAuthType" which can be set to nothing, "basic", or "digest". it's unclear to me whether this is a standard or something that some particular platform is using though.

another link i found suggested that you need to set an instance of Authenticator into the JVM (Authenticator.setDefault()) that knows how to do your authentication. this looks like a good example:
