Struts2 Iteator Tag with object in object

[Srinivas Anumala]

Hi
I have following data structure in my action class.

class   user {
    String name.
}
class Report {
     String ID;
     User user;
}

Action class has list of reports.

List<Report> reports;

I have created list in action class and trying get the values in JSP using <s:iterator> tag.

I am able to get report.id value... but could not get "report.user.name" value

Any suggestion how to retrieve "report.user.name" value in iterator tag .


Thanks

Code please.

Here are the code details.

User Class:

public class User {
	private String name;

	public String getName(){
		return name;
	}
	public void setName(String name) {
		this.name = name;
	}
}

Report Class:

public class Report {

	private String id;
	private User user;

	public String getId() {
		return id;
	}

	public void setId(String id) {
		this.id = id;
	}

	public User getUser() {
		return user;
	}

	public void setUser(User u) {
		this.user = u;
	}

}

Action Class:

public class MyAction extends ActionSupport() {

	private List<Report> reports;
	
	public String execute() {
		reports = new ArrayList<Report>();

		User u1 = new User();
		Report r1 = new Report();

		u1.setName("abc1");
		r1.setId("0001");
		r1.setUser(u1):
		reports.add(r1);

		User u2 = new User();
		Report r2 = new Report();

		u2.setName("xyz2");
		r2.setId("0002");
		r2.setUser(u2):
		
		reports.add(r2);

	}


	public List<Report> getReports() {
		return reports;
	}

	public void setReports(List<Report> r){
		this.reports = r;
	}

}

In JSP, using the following iterator tag to retrieve the data from list:

<s:iterator value="reports">
    	<s:property value="id" />      // This is givng the ID of report.
     	<s:property value="user.name" />   // This is giving nothing.
</s:iterator>

Please suggest how to retrieve "report.user.name" in this case ? Thanks

I don't see anything obviously wrong, but I'm distracted at the moment.

Try assigning each report to a variable and accessing it directly using the iterator tag's "var" or "id" attribute (depends on S2 version) first.

Hi david,

I have tried using iterator tag as shown below.

This also giving me only id, but did not work

<s:iterator value="reports" status="indice" >
	<s:set name="report" value="%{reports[#indice.index]}"/>
	<s:property value="#report.id" />
	<s:property value="#report.user.name" />
</s:iterator>   

<s:iterator value="reports" status="indice" >
	<s:set name="report" var="rp" value="%{reports[#indice.index]}"/>
    	<s:property value="#rp.batchId" />
    	<s:property value="%{#rp.user}.firstname" />
</s:iterator>

What version of Struts?

[David Newton]

That code won't even compile--are you sure you're deploying what you think you are?

If that's not the actual code, then save us both some time--post accurate information.

[David Newton]

And the action configuration.

[David Newton]

It's working fine for me with your original code--your compilation issues might be a problem.

[Srinivas Anumala]

I am using Struts 2.1.8.

Its compiled for me and no compilation errors using both versions of tag code.

Please let me know which version you are using and tag code which you used.

Thanks

Hi David,

Thanks for your time. Please ignore my last comment.

Its resolved.

Thanks

[David Newton]

It's polite to include what the issue was in the followup, but I'm glad you got it resolved.

There is *no* possible way the code you posted above compiled.
