我在 apache wicket 框架中面临这个问题。
WicketMessage: Can't instantiate page using constructor public com.joy.ui.Registration()Root cause:java.lang.ClassNotFoundException: org.apache.wicket.extensions.markup.html.form.select.Select
我已经org.apahe.wicket.extensions.markup.html.form.select.Select在我的项目中导入了jar文件，但错误仍然显示......
import org.apache.wicket.extensions.markup.html.form.select.Select;
import org.apache.wicket.extensions.markup.html.form.select.SelectOption;
