Setting property 'source' to 'org.eclipse.jst.jee.server:GestorContenidoWS' did not find a matching property. Try all the solutions

Question

This is my first post here (but not the first time that I visit the page, I found a lot of solutions here), first of all, sorry for my english I will try to explain myself as best I can.

This question appears another time in this page, but I tried all the solutions that the people post and I still with this problem, well here we go.

I made a project on Eclipse(indigo) for launch like a WebService (I did it before with succes, is not my first time) and when I Run on Server(Tomcat7) all seems fine and the appears this Warning.

WARNING: [SetPropertiesRule]{Server/Service/Engine/Host/Context} Setting property 'source' to 'org.eclipse.jst.jee.server:GestorContenidoWS' did not find a matching property.

Then appear in the Web perspective of Eclipse the page "HTTP 404". I'm telling this because I read in other post that this Warning is not a problem, but seems that it is for me (The project is also vinculated with a JPA Persistence).

.I found two solutions for make dissappear this Warning. First, go to Server Overview and select the option 'Publish module contexts to separate XML files' and then try to Run on server again, but didn't work.

The other option was, remove the project from the server from the Server View. Then run the project under the same server for recreated server.xml, but didn't work also.

Anybody can help me? Maybe the problem of this "HTTP 404 requested resource (/GestorContenidoWS/) is not available." is in another part or its because this Warning?"

The code of my server.xml (without comments) is this:

     <?xml version="1.0" encoding="UTF-8"?>
 --><Server port="8005" shutdown="SHUTDOWN">
  <Listener SSLEngine="on" className="org.apache.catalina.core.AprLifecycleListener"/>

  <Context docBase="GestorContenidoWS" path="/GestorContenidoWS" reloadable="true" source="org.eclipse.jst.jee.server:GestorContenidoWS"/></Host>
</Engine>
  </Service>

Thank you

First of all this is a warning and not an error. So there is no need to worry too much about it. Basically it means, that Tomcat does not know what to do with the source attribute from context.

This source attribute is set by Eclipse (or to be more specific the Eclipse Web Tools Platform) to the server.xml file of Tomcat to match the running application to a project in workspace.

Tomcat generates a warning for every unknown markup in the server.xml (i.e. the source attribute) and this is the source of the warning. You can safely ignore it.
