I progress gently but surely.
I succeeded in displaying a table in a page JSP while passing by DynActionForm
and the tag struts logic:iterate.
But unfortunately the same example doesn't wotk with the tag display.
The example that works:
I have created a plain java bean
public class ItemBean {
public ItemBean() {
}
public void setId(int id) {
this.id = id;
}
public int getId() {
return this.itemId;
}
public void setName(String name) {
this.name = name;
}
public String getName() {
return this.name;
}
public void setPrice(double price) {
this.price = price;
}
public double getPrice() {
return this.price;
}
}
I have created a DynaActionForm bean as follows:
<form-bean name="orderForm" dynamic="true"
type="org.apache.struts.action.DynaActionForm">
<form-property name="itemBeans"
type="java.util.ArrayList"/>
</form-bean>
And I have a jsp like shown below:
<html:form action="">
<table>
<tr>
<td>Id:</td>
<td>Name:</td>
<td>Price:</td>
</tr>
<logic:iterate id="itemBeans" indexId="idx"
name="orderForm" property="itemBeans"
type="com.xyz.ItemBean">
<tr>
<td><bean:write name="itemBeans" property="id"
indexed="true"/></td>
<td><bean:write name="itemBeans" property="name"
size="50" indexed="true"/></td>
<td><bean:write name="itemBeans" property="price"
indexed="true"/></td>
</tr>
</logic:iterate>
</table>
</html:form>
The action that populates the form is the following:
public ActionForward executeAction(ActionMapping mapping, ActionForm form, HttpServletRequest request, HttpServletResponse response) throws Exception
{
Collection beans = new ArrayList();
ItemBean bean1 = new ItemBean();
beans.add(bean1);
bean1.setId(1);
bean1.setName("Toto");
ItemBean bean2 = new ItemBean();
beans.add(bean2);
bean1.setId(2);
bean1.setName("Tata");
// Populate the form from the business data values
BeanUtils.setProperty(form, "itemBeans", beans);
}
Now If I try to use display tag, I modify only the JSP page.
I replace
<logic:iterate id="itemBeans" indexId="idx"
name="orderForm" property="itemBeans"
type="com.xyz.ItemBean">
by the following code
<display:table border="0" pagesize="3" cellspacing="0" cellpadding="0" name="transmissionMonitoringForm" property="calls" scope="request">
<display:column property="id" title="ID" />
<display:column property="service" title="Service"/>
</display:table>
But when I run the application I have the following message:
I do not know how to iterate over 'class java.lang.String'.'
How can I indicate as in the logic tag, the type of the object in the array ?
Thanks a lot in advance
