public void setB(int[] b) {
this.b = b;
}
}

下面的代码如何改用 <c:foreach> 形式？
＝＝＝＝＝＝＝＝＝＝＝＝＝＝＝＝＝＝＝＝
<%@ page contentType= "text/html; charset=gb2312 " language= "java "
import= "java.sql.*, com.infoearth.* "
errorPage= " " %>
<jsp:useBean id= "jobInfo " class= "com.infoearth.JobBean " scope= "request ">
<jsp:setProperty name= "jobInfo " property= "* "/>
</jsp:useBean>
<html>
<head>
<meta http-equiv= "Content-Type " content= "text/html; charset=gb2312 ">
<title> 无标题文档 </title>
</head>
<body>
hello
<%
int[] temp=jobInfo.getB();
for(int i=0;i <temp.length;i++){
out.print(i+ "--- "+temp[i]+ " <br> ");
}
%>
</body>
</html>
------解决方案--------------------
<body>
hello
<%
int[] temp=jobInfo.getB();
List list=new ArrayList();
for(int i=0;i <i <temp.length;i++){
list.add(temp[i]);
}
%>
<c:forEach var= "b " items= "${list} " varStatus= "vsc ">
<c:out value= "${b} "> <br>
</c:forEach>
</body>
------解决方案--------------------
<%@ page contentType= "text/html; charset=GBK " %>
<%@ taglib uri= "http://java.sun.com/jsp/jstl/core " prefix= "c " %>
<%
String[] b=request.getParameterValues( "b ");
request.setAttribute( "b ",b);
%>
<c:forEach var= "temp " items= "${requestScope.b} ">
${temp} <br />
</c:forEach>
public class JobBean{
private int[] b;
public int[] getB() {
return b;
