Hello, I am trying to create custom widget in gwt to use in vaadin, but I can’t seems to deploy war in tomcat.
If I try it now, I get this error when war loads up:

What should I do?
Here is my custom widget:

HeadElement head = getHead();
ScriptElement element = createScriptElement();
element.setSrc(source);
head.appendChild(element);
}
public static void inject(String javascript) {
HeadElement head = getHead();
ScriptElement element = createScriptElement();
element.setText(javascript);
head.appendChild(element);
}
private static ScriptElement createScriptElement() {
ScriptElement script = Document.get().createScriptElement();
script.setAttribute("language", "javascript");
return script;
}
private static synchronized HeadElement getHead() {
if (head == null) {
Element element = Document.get().getElementsByTagName("head").getItem(0);
assert element != null : "HTML Head element required";
HeadElement headElement = HeadElement.as(element);
head = headElement;
}
return head;
}
String uidlId;
ApplicationConnection client;
SimplePanel panel;
public MapyCZWidget(){
super();
inject(MAPY_CZ_SOURCE_API_V4);
inject(MAPY_CZ_INIT_API_V4);
setStyleName(CLASSNAME);
panel = new SimplePanel();
ScriptElement newScript = createScriptElement();
newScript.setAttribute("language", "javascript");
panel.add(new HTML("<div id=\""+ MAPY_CZ_ID +"\" style=\"width:100%; height:100%;\"></div>"));
initWidget(panel);
}
