First, apologies if you've been involved with my recent questions. As this isn't a discussion forum, and comments are limited, my last hope is to ask a specific question with actual code in the hope that somehow I can reach the bottom of my problem.
OK. I've a backing bean called PrismBacking with this pertinent code:
public class PrismBacking {
private ArrayList dataList;
public ArrayList<String> getFeedDataList() {
XMLHandler xmlh = new XMLHandler();
dataList = new ArrayList();
Document doc = xmlh.getDoc(map); // catches removed
// get all the feedNames from the doc, and the feedIds
String[] FeedIds = xmlh.getXMLList("//feed/feed_id/text()");
for (String feedId : FeedIds) {
TaskListData tld = new TaskListData();
tld.setFeedId(feedId);
String feedName = xmlh.getValue("//feed[feed_id='" + feedId +"']" +"/feedname/text()");
tld.setFeedName(feedName);
String[] FTQs = xmlh.getList("//feed[feed_id='" + feedId +"']" +"/ftq/ftq_id/text()");
for (String ftqId : FTQs) {
logger.info("FTQ: " + ftqId);
}
tld.setFTQs(FTQs);
dataList.add(tld);
}
setFeedDataListSize(dataList.size());
return dataList;
}
In class TaskListData,
public class TaskListData {
private String feedId;
private String feedName;
private String[] FTQar;
public String getFeedId() {
return feedId;
}
public void setFeedId(String f) {
feedId = f;
}
public String getFeedName() {
return feedName;
}
public void setFeedName(String fn) {
feedName = fn;
}
public String[] getFTQs() {
return FTQar;
}
public void setFTQs(String[] ftqs) {
FTQar = ftqs;
}
}
so I've got my getters and setters setup, and my XPath all good. In my index.jsp jsf file:
<!doctype html public "-//w3c//dtd html 4.0 transitional//en">

OK, this compiles fine, and runs ok without error. I see from the logger.info line in PrismBacking:
|STDOUT| 2010-01-28 00:02:48,960 | INFO | [http-8989-1]: feedId: 1 | feedSwitch: on | feedName: FEED1
|STDOUT| 2010-01-28 00:02:48,991 | INFO | [http-8989-1]: FTQ: 1
|STDOUT| 2010-01-28 00:02:48,991 | INFO | [http-8989-1]: feedId: 2 | feedSwitch: on | feedName: FEED2
|STDOUT| 2010-01-28 00:02:48,991 | INFO | [http-8989-1]: FTQ: 1
|STDOUT| 2010-01-28 00:02:48,991 | INFO | [http-8989-1]: feedId: 3 | feedSwitch: on | feedName: FEED3
|STDOUT| 2010-01-28 00:02:48,991 | INFO | [http-8989-1]: FTQ: 1
|STDOUT| 2010-01-28 00:02:49,007 | INFO | [http-8989-1]: feedId: 4 | feedSwitch: on | feedName: FEED4
|STDOUT| 2010-01-28 00:02:49,007 | INFO | [http-8989-1]: feedId: 5 | feedSwitch: off | feedName: FEED5
|STDOUT| 2010-01-28 00:02:49,023 | INFO | [http-8989-1]: feedId: 6 | feedSwitch: on | feedName: FEED6
|STDOUT| 2010-01-28 00:02:49,038 | INFO | [http-8989-1]: feedId: 7 | feedSwitch: on | feedName: FEED7
so I know I have FEEDs 1-3 which should have the FTQ number 1 in, in my dataTable. On rendering the page, I see this
This is 'dataTable' demo
id name ftqs
|1| |FEED1| ||
|2| |FEED2| ||
|3| |FEED3| ||
|4| |FEED4| ||
|5| |FEED5| ||
|6| |FEED6| ||
|7| |FEED7| ||
I don't like grovelling. I can't bear long posts either, but I'm working in an environment where I've nobody who knows about these technologies and stack overflow is the only and best place I've found to ask these questions. As I'm at my wits end, I hope you don't mind the extra post length.
My question then is what from the above code needs to change to get the TaskListData String[] member FTQar accessible? At this stage, I'll be honest and say I'm hoping someone could post a modified snippet of my code showing me where I've gone wrong. If it were up to me, you'd get extra points than normal for the right answer.
Many thanks indeed Mark
