How to fix org.richfaces.component.UIDatascroller class not

[thiagu.m]

Hi everyone,

I am using richfaces - 3.1.4.GA in my project

I need to bind rich:datascroller component in my bean class
So I tried to create reference for org.richfaces.component.UIDatascroller class.
But it returns an error msg. :class not found.

In my project classpath has richfaces-api-3.1.4.GA.jar file.
But this jar file does not have that particular class
Help me to resolve this issue

Thanks in anticipation

In my opinion you have to bind a HtmlDataScroller object (see Developer Guide). Anyway it is strange that you can't point to UIDatascroller...

[daniel.soneira]

You need 3 jars in your WEB-INF/lib:

richfaces-ui (contains UIDatascroller)
richfaces-api
richfaces-impl

[alexsmirnov]

All UI... classes placed in the richfaces-ui.jar.
For access to these classes from a EJB layer, you need to put all richfaces libraries ( as far as all these dependensies ) at the EAR level.
To avoid classloading problem, you can define binding class as a UIComponent, and access to it attributes by the attributes Map.
In common, this is a bad architecture solution to manipulate visual representation from a EJB layer. It can be more powerful solution to keep all presentation-layer beans in the web application, and access from them data and business layers EJB beans.

Thank you for your response! Now I fix that NoClassDefFoundError issue
I put 3 jars in your WEB-INF/lib:
richfaces-ui
richfaces-api
richfaces-impl

But I got this Exception

this my ProductTableList.xhtml code

 <h:outputText value="#{pageIndex} / #{pages}"/>
 </f:facet>
</rich:datascroller>

This is my session bean code

@Stateful
@Name("productsearch")
public class ProductsAction implements ProductsLocal, Serializable
{
 private org.richfaces.component.UIDatascroller datascroller;
 public org.richfaces.component.UIDatascroller getDatascroller() {
 return datascroller;
 }


 public void setDatascroller(org.richfaces.component.UIDatascroller datascroller) {
 this.datascroller = datascroller;
 }
}

i try with org.richfaces.component.html.HtmlDatascroller class also
but i got the same Exception
Please help me is there any mistake in my code

But what about using such frameworks as Seam?
