If you look at the properties on your live website node in the repository, what is the value of its "Web Context" property?

Re: RSS problem

Actualy it's the name of the website, the missing part of the generated links.

That *is* the web context. What is the value of that property on your live website node?

Sorry, perhaps I misunderstood your last post. Were you saying that the value of the web context property is "wcmqs"?

It's "somefluFR" and it's the missing part in the links.

No it was for the exemple with basic wcmqs package

Here is the rss page : http://share.someflu.org/somefluFR/actualites/rss.xml

I see what you mean, but I'm puzzled as to how that could be happening. Have you made any changes to the way in which the RSS feed is generated?

Saddly i didn't change anything, if found that rss is not managed by wcmqs when i tried to fix this problem, i'm puzzled too because it works fine in editorial.

Yes, very strange. The *only* thing I can think of is the value of the context property on the live website node. Perhaps if I describe how the RSS is being generated then that will prompt some ideas…

The request for "/any/path/at/all/rss.xml" is routed to a special Spring controller: "org.alfresco.wcm.client.controller.RssController". This simply returns a view name "rssfeed". This view is resolved to a java-backed Surf component (webscript) named "org.alfresco.wcm.client.webscript.RssWebScript".

This outputs the XML, and the relevant line for this topic is:

entry.setLink(urlUtils.getWebsiteDomain(webSite)+urlUtils.getUrl(asset));‍

and the relevant part of that is the call to urlUtils.getWebsiteDomain which looks like this:


    public String getWebsiteDomain(WebSite webSite)
    {
        return "http://'+webSite.getHostName()+(webSite.getHostPort() == 80 ? "" : ":"+webSite.getHostPort()+"/"+webSite.getContext());
    }
‍‍‍‍‍‍

Apart from making a mental note to myself to move the protocol (http) into the repo too, this seems to be correct, and I can't see how it can be missing out the context part. Very perplexing.

Thanks a lot for this explanation of how RSS system works

Well when i tried to found some explanation for this problem i got interested on one file : links-rss.get.rss.ftl


<item>
     <title>${link.title?html}</title>
     <link>${absurl(url.context)}/page/site/${site}/links-view?linkId=${link.name}</link>
     <description>URL:${link.url?html}</description>
</item>
‍‍‍‍‍‍‍

I assume that it's where the asset's link is generated :

<link>${absurl(url.context)}/page/site/${site}/links-view?linkId=${link.name}</link>‍

and maybe the issue is in the ${site} var wich may be empty in the live context, but how and why ? I can't say ^^

Others files like rssfeed.get.html and feed.get.rss.ftl seems to be ok and didn't help me to find any answers

Another thing is when i print webSite.getContext() in any template on the live site, it prints the good context !

So


public String getWebsiteDomain(WebSite webSite)
{
        return "http://'+webSite.getHostName()+(webSite.getHostPort() == 80 ? "" : ":"+webSite.getHostPort()+"/"+webSite.getContext());
}
‍‍‍‍‍‍

should be correct !

In fact it must be, in editorial it's working fine so i'm out of solutions there :s

Re: RSS problem

links-rss.get.rss.ftl is only used by Share - it is not used by the WQS RSS feed generation. In WQS, the RSS link generation is where I described.

I have tried this here, and it works as expected on both editorial and live. The only thing I can suggest if you are able to is to either attach a debugger to the webapp or add some log output around the areas of code that I described above to see if you can track it down.

It's the first time that i look in the java side and i only found Abstract class or Interfaces in the website folder jars like here in alfresco-wcmqs-clientapi-3.4.0.jar :

package org.alfresco.wcm.client.util;

import org.alfresco.wcm.client.Asset;
import org.alfresco.wcm.client.Section;
import org.alfresco.wcm.client.WebSite;

public interface UrlUtils {

    public String getUrl(Asset asset);

    public String getUrl(Section sctn);

    public String getShortUrl(Asset asset);

    public String getLongUrl(Asset asset);

    public String getAssetIdFromShortUrl(String string);

    public String decodeResourceName(String string);

    public String getWebsiteDomain(WebSite ws);
}‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍

or here in alfresco-wcmqs-webapp-3.4.0.jar :

package org.alfresco.wcm.client.webscript;

import java.io.IOException;

public class RssWebScript extends org.springframework.extensions.webscripts.AbstractWebScript {

    private static final String FEED_TYPE = "rss_2.0";
    private static final org.apache.commons.logging.Log log;
    private org.alfresco.wcm.client.util.UrlUtils urlUtils;
    private org.alfresco.wcm.client.CollectionFactory collectionFactory;

    public RssWebScript() {
        //compiled code
        throw new RuntimeException("Compiled Code");
    }

    public void execute(org.springframework.extensions.webscripts.WebScriptRequest req, org.springframework.extensions.webscripts.WebScriptResponse res) throws IOException {
        //compiled code
        throw new RuntimeException("Compiled Code");
    }

    public void setUrlUtils(org.alfresco.wcm.client.util.UrlUtils urlUtils) {
        //compiled code
        throw new RuntimeException("Compiled Code");
    }

    public void setCollectionFactory(org.alfresco.wcm.client.CollectionFactory collectionFactory) {
        //compiled code
        throw new RuntimeException("Compiled Code");
    }
}

Where is the code you mentionned ?

Re: RSS problem

bremmington — Wed, 26 Oct 2011 15:36:02 GMT

The implementation of the getWebsiteDomain method that I mentioned above is in the Client API JAR (the same place as the interface that you listed above). It's in the "org.alfresco.wcm.client.util.impl" package.
