package cn.itcast.b_action;

public class HelloWorldAction {
private String savepath;

public String getSavepath() {
return savepath;
}

public void setSavepath(String savepath) {
this.savepath = savepath;
}

public String execute() {
return "success";
}
}

<!DOCTYPE struts PUBLIC

<struts>
<package name="" namespace="/test" extends="struts-default">
