            <h:outputLabel value="Simple :" for="acSimple" />  
            <p:autoComplete id="acSimple" value="#{myBean.txt1}"   
                    completeMethod="#{myBean.complete}"/>

                    </h:form>
</h:body>
</html>

MyBean.java

import java.util.ArrayList;
import java.util.List;

import javax.faces.bean.ManagedBean;
import javax.faces.bean.RequestScoped;
@ManagedBean(name="myBean")
@RequestScoped
public class MyBean {  

    private String txt1;  

    public List<String> complete(String query) {  
        List<String> results = new ArrayList<String>();  

        for (int i = 0; i < 10; i++) {  
            results.add(query + i);  
        }  

        return results;  
    }  

    public String getTxt1() {  
        return txt1;  
    }  

    public void setTxt1(String txt1) {  
        this.txt1 = txt1;  
    }  
}

So when i run this code, it is showing an error that myBean has no property 'complete'.I am using eclipse and latest version of primefaces.
Am i doing something wrong here?
please help
Thx

Maybe your application is not well deployed. Try calling this `complete` method from a `h:commandButton` for example as its action. — Petar Minchev, Aug 29 '12 at 06:33
see what happens if you change @RequestScoped into view scope — Daniel, Aug 29 '12 at 06:45
which directory your managed bean stored? i think jsf does not scan your annotated managed beans. — erencan, Aug 29 '12 at 07:01
In the future, it would be more helpful if you copypaste the **exact** exception and stacktrace instead of rephrasing it with own words. — BalusC, Aug 29 '12 at 12:27

it is showing an error that myBean has no property 'complete'

Property? This action method shouldn't have been treated as a property in first place. This suggests that the #{myBean.complete} is been treated as a value expression instead of a method expression, exactly as would happen when you inline it in plain HTML like so <p>#{myBean.complete}</p>. This in turn suggests that the <p:autoComplete> tag isn't been recognized as a JSF component at all, but just treated as plain text/HTML. This in turn suggests that either the PrimeFaces taglib URI is wrong, or that the JAR file isn't properly been placed in the webapp's runtime classpath.

Make sure that you use at least PrimeFaces version 3.0 (in older versions, the taglib URI was different) and that the JAR file is been placed in /WEB-INF/lib folder of the webapp.
