p:feedReader noclassdeffound exception

I am trying to create a simple RSS reader in JSF web project (Eclipse).

Here is Primefaces snippet for RSS:

    <h:panelGrid>
    <br/>
<h:outputText styleClass="font1" value="Travel feeds:"/>
<hr/>
<p:feedReader value="http://www.faroo.com/api?q=travel&amp;l=en&amp;src=news&amp;f=rss" var="feed">
    <a href="#{feed.link}" class="link">#{feed.title}</a>
    <h:outputText value="#{feed.description.value}" escape="false"/>
    <p:separator />
</p:feedReader>
</h:panelGrid>

I included this to the very same page:

xmlns:p="http://primefaces.org/ui"

and libraries I included using "Configure build path" are following:

primefaces-6.2-sources.jar, primefaces-6.2.jar, rome-1.0.jar

Also tried to copy them directly to WEB-INF/libfolder, that didn't help either.

So what the actual problem is?

I got exceptions like this:

note The full stack trace of the root cause is available in the Apache Tomcat/7.0.67 logs.

Really can't find a solution to this. What have I missed here? I didn't include needed .jar files or I included them the wrong way?

Solution

  • The solution to this PrimeFaces 6.2 issue mentioned in the PrimeFaces issuelist

    In the PrimeFaces documentation:

    In the migration info:

    You need a newer version of Rome, 1.5.0 instead of 1.0!
