我写的代码，实现分页功能，我不会写web.xml，所以web.xml中信息时MyEclipse自动生成的
下面是写的JavaBean
package goodsBean;
import java.util.ArrayList;
import common.model.*;
import core.query.*;
public class GoodsQuery {
private ArrayList<MerchandiseInfo> list = new ArrayList<MerchandiseInfo>();
private String [] set;
private int pageSize;
private Query query=new Query();
public String[] getSet() {
return set;
}
public void setSet(String search) throws Exception {
set=query.originalQuery(search);
}
public int getPageSize() {
return pageSize;
}
public void setPageSize(int pageSize) {
this.pageSize = pageSize;
}
public ArrayList<MerchandiseInfo> getList() {
return list;
}
public void setList(ArrayList<MerchandiseInfo> list) {
this.list = list;
}
public void result(){
list=query.queryRequestAll(set);
}
}
摆脱各位大神了
--------------------编程问答-------------------- 你把slf4j的jar包拷贝到项目中再试试。 --------------------编程问答--------------------
导入之后又出现了其他的错误

这里是少包的问题
An error occurred at line: 21 in the jsp file: /present.jsp
MerchandiseInfo cannot be resolved to a type
像这种说明你页面上的import导入没有成功，很有可能是因为你的页面不是在webroot下面，
你可以将页面放到webroot下试一试
或者加上<%String path = request.getContextPath（）;String basePath = request.getScheme（）+"://"+request.getServerName（）+":"+request.getServerPort（）+path+"/";%>
这个用myeclipse new jsp时自动生成的相对路径 --------------------编程问答-------------------- 重新deploy一下试试 --------------------编程问答-------------------- 我晕，你后来贴的这些是编译错误。
仔细检查下代码。 --------------------编程问答-------------------- 缺少jar --------------------编程问答-------------------- javax.servlet.ServletException: java.lang.NoClassDefFoundError: org/slf4j/LoggerFactory
少jar包啦 slf4j.jar
--------------------编程问答--------------------
我知道是编译错误，可是一开始到最后没有解决的就是这个编译错误啊，我引入MerchandiseInfo这个了，可是仍然出现编译错误，所以求各位大神帮忙看看啊 --------------------编程问答--------------------
我又新建一个项目，利用原来的方法，添加了，可是还是出现这个类似的问题
