Struts 2 Iterate a List of Objects

[Joe San]

Guys,

I have a List referenced in my model. A call to an action class populates this List in the model. Now, I would need to iterate this List in my JSP page. Below is what I've done in my JSP.

	<s:iterator value="allExamsForTechnology" status="examCount" var="exam">
		<s:if test="#examCount.even == true ">"<tr>"</s:if><td>
		<s:property value="#exam.title"/> - <s:submit theme="simple" type="button" cssClass="hyperlinkButton" value="Start Exam"/>
		<br>
		<s:property value="#exam.description"/>
		</td><s:if test="#examCount.even == true ">"</tr>"</s:if>
	</s:iterator>

When I run my JSP page, I only see the Submit button displayed. Everything else is just not printed.

Am I correctly referencing the allExamsForTechnology in my iterator tag above? The allExamsForTechnology is a field in my Model which gets populated as a result of the action call.

Assuming you are getting proper data to bean, Try to access your bean directly as follows,

<s:iterator value="allExamsForTechnology" status="examCount" var="exam">  
        <s:if test="#examCount.even == true ">"<tr>"</s:if><td>  
        <s:property value="%{title}"/> - <s:submit theme="simple" type="button" cssClass="hyperlinkButton" value="Start Exam"/>  
        <br>  
        <s:property value="%{description}"/>  
        </td><s:if test="#examCount.even == true ">"</tr>"</s:if>  
    </s:iterator>

Data of course if fetched from the database. I get to see it in my action class. This is how my action class looks like:

public class MyAction {

.....
.....
.....
        private ExamContentModel examContentModel;

        // Respective getters and Setters

	/**
	 * {@inheritDoc}
	 */	
	public String getAllExamsForTechnology() {
		System.out.println("The technologyId " + examContentModel.getTechnologyId());
		
		List < Exam > allExamsForTechnology = contentFacade.getAllExamsForTechnology(examContentModel.getTechnologyId());
		
		for (Exam exam : allExamsForTechnology) {
			System.out.println("The Exam Description is " + exam.getExamDescription());									
		}		
		
		examContentModel.setAllExamsForTechnology(allExamsForTechnology);
		
		return SUCCESS;		
	}
}

The Model is as below:

public class ExamContentModel {

        private List < Exam > allExamsForTechnology;

        // Respective getters and Setters

}

I'm now trying to iterate over the allExamsForTechnology. I get to see the Submit button printed five times (I have 5 elements in my List). But I guess, I'm referring my properties wrongly in my struts iterator.

Allright, got it to work. There was a silly typo for a couple of properties in the Exam.java which is why it did not show anything.
