I'm trying to get a hello world PrimeFaces example going. I'm using Eclipse, MyFaces 1.2.7 and Tomcat 6.

I have web project set up with MyFaces so the following JSF works:

Code: Select all

<h:outputText value="Hello1"/>
I added primefaces-1.0.0.RC.jar to the WEB-INF/lib folder, and added this line to the jsp:

Code: Select all

<p:colorPicker ></p:colorPicker>
When I run the app, I see the Hello1 and a button with a button for the color picker that does not appear to be rendered correctly. It's just a plain button with a black square on it.

When I add this XML to the web.xml, I get an error ...

Code: Select all

<!-- PRIME FACES BEGIN -->
  <servlet>
  	<servlet-name>Resource Servlet</servlet-name>
  	<servlet-class>org.primefaces.ui.resource.ResourceServlet</servlet-class>
  	<load-on-startup>2</load-on-startup>
  </servlet>
  <servlet-mapping>
  	<servlet-name>Resource Servlet</servlet-name>
  	<url-pattern>/primefaces_resources/*</url-pattern>
  </servlet-mapping>
<!-- PRIME FACES BEGIN -->
... here's the error:

Code: Select all

javax.servlet.ServletException: Servlet.init() for servlet faces threw exception
	org.apache.catalina.valves.ErrorReportValve.invoke(ErrorReportValve.java:102)
	org.apache.catalina.connector.CoyoteAdapter.service(CoyoteAdapter.java:286)
	org.apache.coyote.http11.Http11Processor.process(Http11Processor.java:845)
	org.apache.coyote.http11.Http11Protocol$Http11ConnectionHandler.process(Http11Protocol.java:583)
	org.apache.tomcat.util.net.JIoEndpoint$Worker.run(JIoEndpoint.java:447)
	java.lang.Thread.run(Thread.java:637)
root cause

java.lang.IllegalStateException: No Factories configured for this Application. This happens if the faces-initialization does not work at all - make sure that you properly include all configuration settings necessary for a basic faces application and that all the necessary libs are included. Also check the logging output of your web application and your container for any exceptions!
If you did that and find nothing, the mistake might be due to the fact that you use some special web-containers which do not support registering context-listeners via TLD files and a context listener is not setup in your web.xml.
A typical config looks like this;
<listener>
  <listener-class>org.apache.myfaces.webapp.StartupServletContextListener</listener-class>
</listener>
	javax.faces.FactoryFinder.getFactory(FactoryFinder.java:106)
	javax.faces.webapp.FacesServlet.init(FacesServlet.java:105)
	org.apache.myfaces.webapp.MyFacesServlet.init(MyFacesServlet.java:94)
	org.apache.catalina.valves.ErrorReportValve.invoke(ErrorReportValve.java:102)
	org.apache.catalina.connector.CoyoteAdapter.service(CoyoteAdapter.java:286)
	org.apache.coyote.http11.Http11Processor.process(Http11Processor.java:845)
	org.apache.coyote.http11.Http11Protocol$Http11ConnectionHandler.process(Http11Protocol.java:583)
	org.apache.tomcat.util.net.JIoEndpoint$Worker.run(JIoEndpoint.java:447)
	java.lang.Thread.run(Thread.java:637)
Please help! Any information is greatly appreciated.

Please see the user's guide for the setup, you have the wrong configuration, it should be;

Code: Select all

  <servlet>
     <servlet-name>Resource Servlet</servlet-name>
     <servlet-class>org.primefaces.resource.ResourceServlet</servlet-class>
  </servlet>
  <servlet-mapping>
     <servlet-name>Resource Servlet</servlet-name>
     <url-pattern>/primefaces_resource/*</url-pattern>
  </servlet-mapping>
And make sure you have p:resources on page and f:view.

Thanks for the help. I did what you said and now I get the following error.

I know I'm doing something simple incorrectly, but I can't see what. I appreciate any help you can provide.

Code: Select all

An Error Occurred:
/index.jsp(14,0) No tag "colorPicker " defined in tag library imported with prefix "p"
Caused by:
org.apache.jasper.JasperException - /index.jsp(14,0) No tag "colorPicker " defined in tag library imported with prefix "p"

	at org.apache.myfaces.application.jsp.JspViewHandlerImpl.buildView(JspViewHandlerImpl.java:486)
I'll include my complete index.jsp and web.xml below.

index.jsp:

	This parameter tells MyFaces if javascript code should be allowed in
	the rendered HTML output.
	If javascript is allowed, command_link anchors will have javascript code
	that submits the corresponding form.
	If javascript is not allowed, the state saving info and nested parameters
	will be added as url parameters.
	Default is 'true'</description>

    <param-value>true</param-value>

  <context-param>
    <description>
	If true, rendered HTML code will be formatted, so that it is 'human-readable'
	i.e. additional line separators and whitespace will be written, that do not
	influence the HTML code.
	Default is 'true'</description>

	If true, a javascript function will be rendered that is able to restore the
	former vertical scroll on every request. Convenient feature if you have pages
	with long lists and you do not want the browser page to always jump to the top
	if you trigger a link or button action that stays on the same page.
	Default is 'false'

Weird, how about this;

Code: Select all

<!DOCTYPE html PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN" "http://www.w3.org/TR/html4/loose.dtd">
<html>
<f:view>
<head>
   <p:resources/>
</head>
<body>


<p:editor />
