需要使用struts 1.3在jsp页面上显示数据

Question

I am trying to read data from a table and display it to the user .

Can anybody tell how to do it using struts 1.3 ?

Answer 1

1. Write an class extending Struts' Action class. This class pulls the data from Database as a List . Pass this data as request attribute, request.setAttribute("myList", list) . Return "success".

2. In your struts-config.xml , map this Action class to a JSP on "success". The request will be forwarded to the JSP.

3. In the JSP, get the list from request by request.getAttribute("myList") . Iterate through the list and print the List .

Answer 2

(Edit: Just noticed this is a 2 year old question)

Don't use the struts tags unless you NEED to. This can be accomplished with jstl/el. So on your Action class you would have something like this:

List<Map<?, ?>> listOfHashMaps = new ArrayList<Map<?, ?>>();
request.setAttribute("listOfHashMaps", listOfHashMaps);

In your jsp:

<c:forEach var="hashMap" items="listOfHashMaps">
    ${hashMap[someInteger]} <%-- To get the value associated with 'key' --%>
</c:forEach>

You can also access the keys/values with:

${hashMap.key}
${hashMap.value}

Respectively.
