NoClassDefFoundError Exception when I use Omnifaces::Ajax::update() method

问题


When I try to run the sample code of Omnifaces library about Ajax::update() method, i get the NoClassDefFoundError exception;

I suppose that it concerns about the client-ids or ids of components, but I do not know how to avoid this exception.

The welcome.xhtml page is the following

<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN"
    "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">

    xmlns:f="http://java.sun.com/jsf/core">

    <body>

        <h3>Update a component programmatically</h3>
        <h:form id="form">
            <h:commandButton value="submit" action="#{ajaxBean.update}">
                <f:ajax />
            </h:commandButton>
            <p>
                It's now
                <h:outputText id="timestamp" value="#{now.toString}" />
            </p>
        </h:form>

        <hr />

        <hr />

        <h3>Execute a callback script programmatically</h3>
        <h:form>
            <h:commandButton value="submit" action="#{ajaxBean.callback}">
                <f:ajax />
            </h:commandButton>
        </h:form>

        <hr />

        <h3>Add arguments to the JavaScript scope</h3>
        <h:form>
            <h:commandButton value="submit" onclick="$('#showData').empty()"
                action="#{ajaxBean.argument}">
                <f:ajax />
            </h:commandButton>
        </h:form>
        <ul id="showData"></ul>
        <h:outputScript>
             function showData() {
                 var data = OmniFaces.Ajax.data;
                 var $showData = $("#showData");

                 $.each(data, function(key, value) {
                    $("&lt;li&gt;").text(key + "=" + JSON.stringify(value)).appendTo($showData);
                });
             }
         </h:outputScript>

</body>
</html>

And the AjaxBean.java bean is the following

package com.tutorial;

import java.util.Arrays;
import java.util.Date;
import java.util.HashMap;
import java.util.Map;

import javax.faces.component.UIData;

import org.omnifaces.util.Ajax;

public class AjaxBean {

    public void update() {
        Ajax.update("form:timestamp");
    }

    public void callback() {
        Ajax.oncomplete("alert('Hi, I am the oncomplete callback script!')");
    }

    public void argument() {
        Ajax.data("foo", "bar");
        Ajax.data("first", "one", "second", "two");
        Map<String, Object> data = new HashMap<>();
        data.put("bool", true);
        data.put("number", 1.2F);
        data.put("date", new Date());
        data.put("array", new Integer[] { 1, 2, 3, 4, 5 });
        data.put("list", Arrays.asList("one", "two", "three"));
        Ajax.data(data);
        Ajax.oncomplete("showData()");
    }

}

The stacktrace is:

Any help would be appreciated.

Thanks.


回答1:


while not taking a deep look in the code you posted, NoClassDefFound exceptions are usually caused by linking problems and are unrelated to actuall code written. make sure you include in your classpath everything needed




回答2:


If you can, put your project on fresh servlet container installation.
