package org.apache.struts.config does not exist 在线等待急................

[gotwtanxhj]

package org.apache.struts.webapp.examples;
import org.apache.struts.config.FormBeanConfig;
public final class CustomFormBean extends FormBeanConfig {
private String example = "";

public String getExample() {

return (this.example);

}
public void setExample(String example) {

this.example = example;

}

}
错误是:
CustomFormBean.java:2: package org.apache.struts.config does not exist
import org.apache.struts.config.FormBeanConfig;
^
CustomFormBean.java:3: cannot resolve symbol
symbol : class FormBeanConfig
location: class org.apache.struts.webapp.examples.CustomFormBean
public final class CustomFormBean extends FormBeanConfig {
