Looping through a list using logic tags problem

aadz5 · March 25th, 2006, 07:42 PM

Hiya Guys,

I want to loop through an array list and then display its contents. This is what I have so far:

<logic:iterate id="settings" name="user" property="userSettings">
    <tr>
        <td>Hello baby!</td>
    </tr>
</logic:iterate>

Can someone please help.

Thanks

Hiya Guys,

An update to the problem, I now know how to display the value stored in the scripting variable however I wish to do display text fields dynamically with the property value of the string values in the collection. My code is as follows:

<%@ taglib uri="/tags/struts-html" prefix="html"%>
<%@ taglib uri="/tags/struts-logic" prefix="logic"%>
<%@ taglib uri="/tags/struts-bean" prefix="bean"%>

<jsp:useBean id="user" scope="session" class="mnaAccounting.User" />

<html>
<head>
    <title>New Page</title>
    <h1>Test Test Test</h1>
</head>

<body>

<table>
<html:form action="accounting">
    <tr>
        <td><p/>Welcome <bean:write name="user" property="firstName" /> please enter you account details</td>
    </tr>
    <logic:iterate id="settings" name="user" property="userSettings">
    <tr>
        <td><html:text property="<%=(String)settings%>"/></td>
        <td><%=settings%></td>
    </tr>
    </logic:iterate>
    <tr>
        <td><html:submit /></td>
        <td><html:cancel /></td>
    </tr>
</html:form>
</table>

</body>
</html>

I get this error:

exception

javax.servlet.ServletException: Cannot find bean org.apache.struts.taglib.html.BEAN in any scope

What am I doing wrong?

Hi People,

I guess no one knows the answer, the problem was in the mapping of the action with the input page, got it sorted though. I have another problem though which I will raise in a second report.

Anyways people Enjoy the struts!
