I need to export the values in 4 column.values for 3 columns are populating properly. I am having trouble with 4th column which is organization column.it is multivalued column.i.e.: it has multiple values.

I have tried to convert from object to String for organization column but didnt help.

Please see the code below:

String appname = "abc";
String path = "//home/exportfile//";
String filename = path+"ApplicationExport-"+appname+".txt";
String ret = "false";

QueryOptions ops = new QueryOptions();
Filter [] filters = new Filter[1];
filters[0] = Filter.eq("application.name", appname);
ops.add(filters);

List props = new ArrayList();
props.add("identity.name");

//Do search
Iterator it = context.search(Link.class, ops, props);

//Build file and export header row
BufferedWriter out = new BufferedWriter(new FileWriter(filename));
out.write("Name,UserName,WorkforceID,organization");
out.newLine();

//Iterate Search Results
if (it!=null)
{
while (it.hasNext()) {

//Get link and create object
Object [] record = it.next();
String identityName = (String) record[0];
Identity user = (Identity) context.getObject(Identity.class, identityName);

//Get Identity attributes for export
String workforceid = (String) user.getAttribute("workforceID");

//Get application attributes for export
String userid="";

List links = user.getLinks();
if (links!=null)
{
Iterator lit = links.iterator();
while (lit.hasNext())
{
Link l = lit.next();
String lname = l.getApplicationName();
if (lname.equalsIgnoreCase(appname))
{
userid = (String) l.getAttribute("User Name");
List orgList = l.getAttribute("Organization");

}
}
}

//Output file
out.write(identityName+","+userid+","+workforceid+","+org);
out.newLine();
out.flush();
}
ret="true";
}
//Close file and return
out.close();
return ret;

orgList is arraylist.that means..there may be multiple organization value for the same users.
so,output should be like this,

Name,UserName,WorkforceID,organization
thomas,thomas01,123,healthcare
thomas,thomas01,123,finance
