JtextField and list of data

Hi everyone (and sorry for my english language....).
I've this problem:
I've a Frame with a JtextField and a button. When I click on this button, I want to show a list of data from a database and then I must choose a value that must go to the JtextField.
Have you an idea how I can implement this? Sorry for this generic question, but I don't know how to do..
Thank you!

As to your question.
I've a Frame with a JtextField and a button. When I click on this button, I want to show a list of data from a database and then I must choose a value that must go to the JtextField.
Have you an idea how I can implement this? ..Sure, plenty of people. But they will want to know exactly what you are having trouble with. E.G.
- Getting data from a DB.
- Putting data into a JList.
- Adding listeners to that JList so that choices are acted on, rather than simply high-lighted as the selection.
- Using the event provided to the listener, to update the JTextField.
- Adding a JTextField and JList to a JFrame using layout managers.
If your answer is 'all of that', then I suspect they would be tempted to:
a) Advise you to put this project aside until you have considerably more experience.
b) Refer you to the [Java Tutorial|http://java.sun.com/docs/books/tutorial/].

Generating annual report and list the data into JTable

Hi, I am stuck with my project. I know that my logic is wrong, but I couldn't figure out the solution. Please help me.
I hava a database, one of the table is the booking information.
I need to generate a report which shows the number of booking for each companies for each month.
I have three data in my database, two different companies(XX and YY), with three different months(Jan, Feb, Jul).
The problem that I encountered is that the data shown is inaccurate. It showed 6 rows of data, and the number of booking is incorrect.
It showed :
Company Jan Feb Mar Apr May Jun Jul Aug Sep Oct Nov Dec
XX 1 0 0 0 0 0 0 0 0 0 0 0
XX 1 1 0 0 0 0 0 0 0 0 0 0
YY 1 1 0 0 0 0 1 0 0 0 0 0
How can I loop for different companies and add the number of booking each time and get the right output as follows?
Company Jan Feb Mar Apr May Jun Jul Aug Sep Oct Nov Dec
XX 1 1 0 0 0 0 0 0 0 0 0 0
YY 0 0 0 0 0 0 1 0 0 0 0 0
This is my partial code:
ArrayList stringList = dao.retrieveAllBooking();
for (int i = 0; i < stringList.size(); i++) {
ab = (AllBooking) stringList.get(i);
d = ab.getDATE_OF_USE_TO();
StringTokenizer ss = new StringTokenizer((String) d, "/");
String day = ss.nextToken();
String month = ss.nextToken();
String year = ss.nextToken();
Org = o.getORG_ID();
if(month.equals("JAN")){
JanDR++;
if(month.equals("FEB")){
FebDR++;
if(month.equals("MAR")){
MarDR++;
if(month.equals("APR")){
// Apr = ab.getNO_OF_REQ();
AprDR++;
if(month.equals("MAY")){
//MayDR = ab.getNO_OF_REQ();
MayDR++;
if(month.equals("JUN")){
// Jun = ab.getNO_OF_REQ();
JunDR++;
if(month.equals("JUL")){
JulDR++;
if(month.equals("AUG")){
AugDR++;
if(month.equals("SEP")){
SepDR++;
if(month.equals("OCT")){
OctDR++;
if(month.equals("NOV")){
NovDR++;
if(month.equals("DEC")){
DecDR++;
Object[] data={Org,JanDR, FebDR, MarDR, AprDR, MayDR, JunDR, JulDR, AugDR, SepDR, OctDR, NovDR, DecDR, JanSR, FebSR, MarSR, AprSR, MaySR, JunSR, JulSR, AugSR, SepSR, OctSR, NovSR, DecSR};
tableModel.addRow(data); //add the data to the table.
I'll appreciate for your help. Thanks.

Off hand, it appears perhaps under certain circumstances you need to insert a new record, whereas under other circumstances you need to update (that is to say modify) the record by retrieving it, changing it, then updating it. If you pepper your code with System.out.println() statements, you can see where your problems occur in the code.
I say you may have inserted a record instead of updated due to your statement here. Looks like XX should have been one record rather than two.
Got:
XX 1 0 0 0 0 0 0 0 0 0 0 0
XX 1 1 0 0 0 0 0 0 0 0 0 0
YY 1 1 0 0 0 0 1 0 0 0 0 0
Expected:
XX 1 1 0 0 0 0 0 0 0 0 0 0
YY 0 0 0 0 0 0 1 0 0 0 0 0

I'm unclear on settings and misplaced some data, Please help?

I have been using Media player for music but decided to finally use my airport express since the software is fixed. I downloaded Itunes to my Windows XP notebook. All the Mp3 that were in Media Player (ie. my music) transferred just fine. I then decided I need more room in my home so began importing all my CD's so I could store the original discs. I imported as .wav files so as to retain as much clarity as possible. I made the assumption that Apples' lossless would be as limiting as Media Player's which won't let you play your on other music players such as Itunes.
I only have 90GBs on my hard drive so it was filling up fast. I then decide to move all the music files to an external HD (attached to my notebook currently) which, upon completion of the CD importation, I could attach to my home server and make available to all home computers. The new directory was F:music. I moved all music files in my music that consisted of MP3 and imported wav files. I then continued to import to my notebook.
After another round of moving the files, I realized that I should leave the external drive attached to my notebook and Import the files to the external drive. Here is where the wheels BEGIN to fall off. I should have attached the External drive from the beginning but hindsight is 20/20.
Bare in mind, the rest of this is likely out of sequence because I have made so many changes and tried to fix things.
I went to edit, then preferences and changed "Itune Music folder location" to F:music. Within the music folder I now had all my artist's folders. Within the artist's folders were the albums. Within the albums are all the individual tracks from the albums. Incidentally, when I imported the CDs as wav, all info was available and copied. I could see all the data (ie wav file itself, album cover, year, artist, album name, genre, etc...) in Itunes and in the folders by checking the properties of the songs. In addition to all the artist's folders in alphabetical order in F:music, Itunes folder was also listed next to the INXS folder. Within the itunes folder, were the subfolders: itunes Music, itunes Library.itl, and itunes Music Library.xml. However, the same were still in the my music folder in my documents on the C:. I'm not sure it was there as a pointer of some sort or not.
Ok, not sure what was going on, I began trying to fix, what I percieved as little problems. I tried various things like checking and unchecking "keep itunes music folder organized". I also checked and unchecked "copy files to itunes music folder when adding to library". Probably tried to combine the Library.itl at some point.
After a while, I when I started itunes the MP3 files were theere and listed all data. However, the imported files, althought available, only listed the track # and song title. All other data was missing in itunes. I could play the songs but they were sorted by track and titles. I had dozens of track 01 through 09 and etc... The info was still in the original artist's folder but not in itunes.
I then tried restores to previous times to fix this with out success. I moved things around uninstalled and maybe even accidentally deleted things, however unlikly. I also restored everything in my recycling folder just in case.
I now have a totally screwed up list, with exception of the original MP3s. The song data in now missing from the folders, although track # and song title still exist.
95% of the music is in an unknown artist's file in F:
Is there a way to rebuild this without loading in the individual CDs?
I've seen at Gracenote that there seems to be a software provider that has something for DJs that only use vinyl recordings.
I can apparently use just the name and the software will propose all options.
Does anyone have experience with this?
Can itunes do this?
Should there be itunes music and library folders in the default C:My documents/my music folder and in the F: or should they be combined or one deleted?
Should I check "keep itunes music folder organized" and "copy files to itunes music folder when adding to library".
And if so, how do I keep from duplicating files which takes up massive space in any drive?
Is wav the best format to use for true Audio file duplication.
If itunes lossless is better, can other media players play the files?
I've search forums and can't seem to find my answers. I have read contradictory informatin and am looking for a clear instruction. I realize that my be difficult based on all the changes that I made but moving forward, I'd like to know the correct proceedures.
I appreciate any help I can get.

Well, in my opionion, you've moved things around so much, it would be better to just clear your current iTunes library and rebuild it.
IMPORTANT - I am talking about clearing the iTunes library file, not deleting song files from your hard drive.
I personally never use WAV files, because I like the tags that come with MP3. I'm a pleasure listener - I don't need WAV files for professional reasons.
When I first got iTunes, yeah, I took the default settings and ripped all my CDs in AAC format (they have .m4a file extensions). I regret this, in one way, because they won't work in other Windows applications & other portable devices. But, they sound great on my iPod and don't take up so much drive space as other formats.
edit: I've no idea what you're talking about with the GraceNotes vinyl lookup. AFAIK, you're going to have to re-rip the CDs in a non-WAV format to get the ID3 tags. But you can google to find more info on that.

When formatting your column to date/time, pick Date & time, and then pick the letter i in the circle to the right. Then scroll down and pick "No time"

Date Parameters and List of Values (error message date format cannot be nul

I'm new to BI Publisher. I began with a simple report that has 4 parameters. The parameters are center code, sales date, customer number, and job number. I am trying to create a list of values on my customer number based on the center code and sales date entered by the user. My query for my LOV is:
select customer_nbr
from ticket
where center_cd = :center
and trunc(trans_date) = :salesDate
salesDate is defined as a date parameter with a format of MM-dd-yy. It's default value is 04-10-07.
When I attempt to view my report after adding the LOV, I receive the error:
Date format can not be null.
What am I doing wrong? Also, I would like the salesDate to default to the current date. I have tried using sysdate as the default value. This isn't working. The salesDate defualts to null when it is set to sysdate.

"Date - allows the user to enter a date as a parameter. Note that the data type must also be "Date" and the format must be Java date format."

OModel Data and List BindItems message

I have an sap.m.List that I aggregate with data from an oModel. But I am coming back with this message that I see from SMP 2.3 logs because my List is empty; I've validated that the query is correct and does return data when I run this same query from Chrome.
The error message from SMP 2.3 logs:
The request URI is not valid. The segment 'ApplicationServiceSet' refers to an entity set and not to a single entity
When run through the browser this is the result:

My binding to my List is this:
.....var omodel = sap.ui.model.odata.ODataModel(serviceURL, false, username, pwd);
var oCore = sap.ui.getCore().setModel(omodel);
myList.bindItems({
 path: /ApplicationServiceSet,
 template: mytemplate,
 filters: [f1, f2, f3]
I have this same setup on another application that uses this exact code but calling a different OData Model and that is working fine. The difference is that the model on the other application is a list of fld3, in this case is a list of materials base on location and date.
In this issue, the user searches specifically for material#, location and date so I expect only one result. I was thinking that the code should work I just need to change the sPath, field names are even the same. Only difference is that this List, though aggregated, should still work. However, I get the above message of "refers to an entity set and not a single entity"......
So not sure if there's a different way of implementing how a record is returned when it comes to using the API or if this is something on the BAPI end?
Any help is greatly appreciated. Thanks.
J

Thanks Jamie. I do have my filters defined and for testing, I have hard coded the values. There's a few more info I should have added.
1. I have the same application using the same code for another service which works fine. Since the query is essentially the same, I just needed to change the URL to point to the right service and the correct sPath
2. We are going through SMP 2.3 to get to Gateway so the alias or the end point is: http://mydomain:port/com.my.applicationID
3. I used RESTcClient to test the end point directly to GW and it is fine. I don't think this is an SMP issue, but I'm not sure.
Thanks for the reply

Since the iPhoto upgrade, my albums are gone and everything is listed by date

yosemite....since iphoto upgrade, all photos are listed by date and not the albums..How can I get my albums back?

ryanepps wrote:
Not sure why they did that, surely it makes more sense to place all the albums directly under the album tab instead of a sub folder... but hey, whats an extra click...
Albums in Photos are not the same as Events in iPhoto. For those users that had dozens or even hundreds of Events, it's a blessing that Apple grouped them into a single folder. Gives the users the opportunity to organize (or delete) them as they wish.

Pick list release date and picked date

Hello, I need to prepare a query where I need to select the b1 pick list release date and pick list picked date.
Does b1 store these pick list dates somewhere in the system?
Thanks

I don't think that the APKL or the ADOC store the the release date. And I also have seen that the pick date is not changed after the user picked the goods and update the pick list. I keep seen the pick date in the OPKL = to the create date in the OPKL. And the update date we can't really relly on it because after picking the goods some days after the user can update for example a UDF and then save the pick list and this field is updated again...
Any ideas?

Set List datefield to future date and disable all date behind current date?

Is it possible to set date to future date (atleast 2 week) and all prior date should be grayed out . User will not able to select behind current.
Is it possible with OOB option. JQuery work around also fine.

FutureDate - datatype will be Datetype as Calculated column formula 'Today+14'
please 'Propose as answer' if it help you, also de-mark it if it didn't. Thank you!
Also Place a validation rule as below which will restrict all previous date
[FutureDate] > (Today()+14)
User cant save that item if future date is not greater that today play another 14 days.
Hope this will help !

SharePoint 2013 List - Multiple Data Types in the Same List

In the same SharePoint 2013 list in Data Sheet View, I want to have one column where my end users enter inputs for KPIs. There are 3 groups of KPIs (A, B and C) and they each have different data types (A-string, B-decimal, C-percentage) and I want to be
able to base their input options off of the KPI type
Does anyone have any suggestions on how I can leverage my parent-child relationships so when an end user...
1. Picks KPI type A, they can select from a choice filed (Green, Yellow, Red)
2. Picks KPI Type B, they can enter a decimal (-1.000 to 2.000)
3. Picks KPI Type C, they can enter a percentage (-100.00% to 100.00%
I'm using if I want to keep this in one list, one column and in data sheet view that the out of the box solutions won't meet my requirements. I was looking at some solutions from Bamboo (Lookup Selector Column) but don't think that applies here.
Thanks!

Hi Johnny, you can accomplish this using cascading lookups in InfoPath if that program is available to you. Otherwise, if you want a 3rd party product, we use the Kwiz cascading lookup and it's worked wonders for us:

Obtaining the list of data interfaced out of SAP HCM

Hello,
we got a good challenge from our partners in the business organization that we support. The Data Privacy officer on the business partner side would like to know:
- what other systems are "takers" of the data from our SAP HCM instance
- what data pieces (what tables, fields...) are being interfaced out
- what is the frequency of that
We are trying to maintain the document whenever a new interface is being built but in practice you know how it looks like.In order to have 100% confidence in the anwser I would want to pull such list from the system. Is there a way to do that? What would you suggest?
Regards,
Pawel

Try the function below, pass the item name and get the Data provider for that particular item, you will have to do this for all the items in the template.
function getDPName(item){
 prop = SAPBWGetItemProp(item);
 var tableHidden=true;
 if (prop != null){
 for(i=1;i<prop.length;i++){
 if (prop[0] == "DATA_PROVIDER")
 return prop[1]
 }//end for
 }//end if
}//end function
Thanks.

How to filter the list of data

I am using af:inputComboboxListOfValues to display drop down list of data. The list is binded to a LOV.
I have a requirement that if the value is used in other place, I should not get it listed on the drop down list. I research doc that it let me use "launchPopupListener" to filter the list of data. As a test code, I coded like this:
public void launchListener(LaunchPopupEvent launchPopupEvent) {
// Add event code here...
DCBindingContainer bindings =
(DCBindingContainer)BindingContext.getCurrent().getCurrentBindingsEntry();
DCIteratorBinding dcItteratorBindings =
bindings.findIteratorBinding("PersonVO1Iterator");
dcItteratorBindings.getViewObject().setWhereClause("PersonEO.FIRST_NAME <> 'John'");
dcItteratorBindings.getViewObject().executeQuery();
But it does not work. It seems that 'John' is removed from VO but doesn't removed from UI combo box drop down list.
What can I do to fix it?

Thanks.

Dependant Dropdown - Format string as date?? And hopefully two dates as a range?

I'm stuck - been trying to figure this out all afternoon and with a launch in 2 days am probably missing something obvious....so please help me!! hehe I have the a dependent drop down. The first one is a list of Locations and the second one is then populated by a list of dates that events will be at those locations. 1st problem: when I've been hand coding this drop down I am able to show the start and end date with something like: echo date( 'l, M j', $row_getalldates['date_start']).' - '.date( 'M j',$row_getalldates'date_end']); b How do I translate that into one string to display in wdg:displayfield="" 2nd: Right now since I can't get the two values in...I'm just going with one value so I can continue with development till I figure it out.

Don't mind if I have to hard code as the site's lifespan is short

Hi Amanda,
how about preparing that within your query by using a CONCAT function and by formatting the dates right in here, like:
SELECT CONCAT(DATE_FORMAT(date_start, '%I, %M %j')," - ",DATE_FORMAT(date_end, '%M %j')) AS date_range ?
The wdg:displayfield expects one table column, and in this case it would be the alias column "date_range".
Works ?
