To update the JComboBox selection
Hi,
I have JTable and JComboBox on a Frame. I got data into table and combo box from database. Now I want to change the combo box value depending on a JTable's row selection. I'm calling jComboBox1.getSelectedItem() , but there's changes in the JComboBox .
Please help, if you know how
I mean I just want to know how can I request the selection of the combo box

Need image to update with JComboBox selection
hello, i have code here that loads an image from a JFileChooser dialog when "Add Image" is clicked, the images name and path is stored in a JComboBox, and the image name is displayed. As more images are added to the JComboBox, I would like to be able to have the picture displayed in concurrence with whatever image is selected from the comboBox. For instance, if Jessica.jpg is selected in the JComboBox, i need Jessica.jpg to be loaded into imagePanel. Here is the code. The problem lies within the JComboBox's "itemStateChanged" I believe... This is what must be used (i think) to update the pictures in the imagePanel when the combobox is manipulated....

If you need further help then you need to create a [url http://homepage1.nifty.com/algafield/sscce.html]Short, Self Contained, Compilable and Executable, Example Program that demonstrates the incorrect behaviour, because I can't guess exactly what you are doing based on the information provided.
And don't forget to use the [url http://forum.java.sun.com/help.jspa?sec=formatting]Code Formatting Tags so the code retains its original formatting.
In the meantime I suggest you read the Swing tutorial on [url http://java.sun.com/docs/books/tutorial/uiswing/components/combobox.html]How to Use Combo Boxes for a working example that does exactly what you want. -

So please can anyone there tell me how can solve this problem.

jdev version 11.1.1.4.0Hi Frank
in your AM configuration, set the locking behavior to optimisticIts already optimistic.
is bad coding practice. You should perform updates through teh ADF binding layer and not directlxy against the Application Module Impl class. You can get the >current row from the iterator the table is bound to and set the attributes on itI changed my code to following
RowKeySet rs = getCalcTable().getSelectedRowKeys();
Iterator it = rs.iterator();
DCBindingContainer bindings =
(DCBindingContainer)BindingContext.getCurrent().getCurrentBindingsEntry();
DCIteratorBinding empIter =
bindings.findIteratorBinding("Entries_VO1Iterator");
StringBuilder sb = new StringBuilder();
RowSetIterator empRSIter = empIter.getRowSetIterator();
Row currentRow = null;
while (it.hasNext()) {
Key key = (Key)((List)it.next()).get(0);
currentRow = empRSIter.getRow(key);
break;
Entries_VORowImpl row=(Entries_VORowImpl)currentRow;
row.setSubject(subject);
ClobDomain c=new ClobDomain(toXML().toString());
row.setXmlcontent(c);
row.setDescription("");
BindingContext.getCurrent().getCurrentBindingsEntry().getOperationBinding("Commit").execute();
But it still gives me same error.
<Utils> <buildFacesMessage> ADF: Adding the following JSF error message: Failed to lock the record, another user holds the lock.
oracle.jbo.AlreadyLockedException: JBO-26030: Failed to lock the record, another user holds the lock.
Any suggestion appreciated..

How to update the second JComboBox according selection in first JComboBox??
I am having a hard time to update the second JcomboBox according to the selection of the first JcomboBox. For example, the content of the first JcomboBox is {city, rent}. When "city" is selected, the content of the second JcomboBox should be set to a number of cities. When "rent" is selected, the content of the second JcomboBox should be set to a range of rent.
Since I have to detect the selection in actionperformed(), where the JcomboBoxes have been added to a Panel, and my JFrame setContentPane() to this Panel, I don't know how to update the JFrame or the Panel. I can make the old JFrame disappear and a new JFrame appear instead, but this is not what I want. I tried method update(Graphics) and removeAll(), and never made it work.
I would greatly appreciate if anyone could give me any help.Thanks for your response. I fixed the problem in the following clumsy way:
frame.getContentPane().remove(mainPanel);
mainPanel.remove(box2);
if(box1.compareTo("city")==0)
box2 = new JComboBox(cities);
else if(box1.compareTo("rent")==0)
box2 = new JComboBox(rents);
else if(box1.compareTo("type")==0)
box2 = new JComboBox(types);
box2.setBounds(305, 30, 90, 20);
mainPanel.add(box2);
frame.getContentPane().add(mainPanel);
Maybe there is a better way, but I don't know, and I don't understand your suggestion, could you further explain it? Thanks a lot.

How to have a JComboBox display an item different from the one selected
Hello,
I have a JTable (single column). I have set this column cell editor to be a JComboBox...
JComboBox stdComboBox = new JComboBox();
TableColumn column_zero = stdTablewCombo.getColumnModel().getColumn(0);
column_zero.setCellEditor( new DefaultCellEditor(stdComboBox) );I have added a lovString array say {"A", "B", "C") to this stdComboBox. However, when the user selects a value from this list, I need to display a value from another lovString array say {"1", "2", "3"}. So if the user selects A then 1 needs to be displayed.
I have a TableModelListener on this table that is getting me the correct selected index for any of the JComboBoxes on any of the rows. But I am little lost on how to display the value from the 2nd list.
Thanks.Yes...but do I do that in the TableModelListener ?
This is what I've tried in the TableModelListener:
public void tableChanged(TableModelEvent e)
System.out.println(e.getSource());
if(e.getType() == TableModelEvent.UPDATE)
TableModel model = stdTablewCombo.getModel();
int row = e.getFirstRow();
this.cellValue = ((String)model.getValueAt(row, 0));
if (cellValue != null)
this.selectedIndex = this.stdComboBox.getSelectedIndex();
System.out.println("Selected Index:" + this.selectedIndex);
if (this.selectedIndex >= 0)
String valueToSet = this.lovStringB[this.selectedIndex];
model.setValueAt(valueToSet, row, 0);
else
System.out.println("Value in cell is not from List");
}It returns the selectedIndex value allright.
It sets the value of valueToSet string allright.
it also does the model.setValueAt allright....but this triggers a tableChanged event and it goes back up - this is also fine. However, when it now comes back to the this.selectedIndex = , this again returns the index of the original selection and not a -1 (for values not in the ComboBox list). This makes it go into an infinite loop and gives me a StackOverflowError.

"All of the Playlists Selected for Updating No Longer Exist"
My family has 2 ipod shuffles. After purchasing a Nano recently, I inserted the cd that came with it. Apparently the existing iTunes software was removed and reinstalled. At any rate, the library still shows all the original songs, but when the Nano is plugged in, iTunes immediately gives a prompt stating "Songs on the iPod *** cannot be updated because all of the playlists selected for updating no longer exist." The library is there, the playlists that were there are there, and I can play the songs on my cpu. Is there anything I can do besides completely uninstalling everything and starting over?

I just updated my iPhone 4 to iOS6. In the process, I ran into a problem and had to restore factory settings. After syncing the phone, I see that 218 apps need to be updated. When selecting "update all," it says "Cannot Download. There is not enough available local storage to download these items. You can manage your local device storage usage in Settings."
How can this be the case when I haven't changed any apps from before updrading to iOS6, and I don't have any music yet on the phone? Why is it telling me there is not enough local space?Hi RileyAvaCadenRiver,
If you recently updated your iPhone to iOS7, you will need to update iTunes on your computer to iTunes 11.1 or newer for it to correctly recognize the iPhone. You may find the following link helpful:

Don't know where to get help. I just updated the software and I am having issues with not being able to update Aps or install new ones. The circles just spin and Aps just say "waiting." I tried running a diagnostic with the apple store and it came back with "power issues" (?) as a result. It wouldn't let me select an option to see what steps I could take to fix it, it just backed out of the page. I just don't know what to do.....
Hi,
Thank you for your reply, I did go to my general settings, but for some odd reason I don't have a restrictions setting, or a reset setting. I thought I could reset all the setting to see if it could be that, but as I said there aren't any.
My husband also has the iPad 2, and also did the software update and hasn't had any problems at all. I took both iPad's and compared the settings thinking maybe there could be a setting that could have been changed when the update was done. -
When my iPod Touch is connected to my Mac, and I select Update to update the software of my iPod Touch, I get a message saying that my iTunes software is current, but it will not update my iPod Touch software. Is there a bug in the iPod program?

I accidently deleted the playlist selected for updating thing...
i was adding new songs to my ipod and i guess there were too many songs there so it asked me if i wanted it to choose some songs randomly...
so i chose "ok" but actually i didnt really want it to choose songs on its own so i deleted the list that was automatically created by itself and decided to delete some songs on my own...
after doin that, i tried to update it but now it says i cant do it because i deleted that list...
it says "songs on the ipod "stephanie kim" cannot be updated because all of the playlists selected for updating no longer exists"
i turned my computer off and tried it again several times but it wont work...
and all the songs in my ipod are gone now...
is there anything i can do?http://support.apple.com/kb/PH10918

Why can't I select or update the Record using the PreparedStatement?
the DB is oracle9i,here is the test table
test
id number;
name char(10);
intro char(10);
I have insert a record in the table.
Now I will select or update the record by using the PreparedStatement here is my code:
sqlStr = "update test set intro = ? where name =?";
PreparedStatement stmt = conn.prepareStatement(sqlStr);
stmt.setString(1,"my name is irixwang");
stmt.setString(2,"irixwang");
int is = stmt.executeUpdate();
if (is >=1 )
System.out.println("ok");
It will not work ,but where I change the update condiction as followed:
sqlStr = "update test set intro = ? where id =?";
PreparedStatement stmt = conn.prepareStatement(sqlStr);
stmt.setString(1,"my name is irixwang");
stmt.setInt(2,100);
int is = stmt.executeUpdate();
It works well,why?
please help me!thk!!!!I doubt it works "well" in either case since you are inserting a string that is longer than 10 characters into a field that only holds 10 characters. But to your question....
A char data type holds a fixed number of characters - in your case 10.
Because it holds 10 characters it will never hold 9, regardless of what you think is in the field it will always have 10 characters in it. The value you are using for query for name is 9 characters. Since 9 characters, regardless of content, will never be equal to 10 characters there is no way that it will update.
So your choice is to either use a varchar, which holds a variable number of characters, or to always use 10 characters for your query (pad it with spaces.) -
Updating the Leave Information (dates selected) from MSOutlook to SAP ESS
Hi Forum,
I had a scenario where I need to use Microsoft Outlook as an interface and the leave information selected in outlook calender should be updated to SAP ESS. Does Any one worked on similar kind of scenarios ? I would like to know if any API is available to interface between MS Outlook and SAP.

Regards
RameshHi Manoj,
Thanks for your reply. I am looking for a Java API using which i can read the calender information in outlook (dates selected and saved by the user). If I can get this dates information i could think of updating the same dates (leave info) to SAP ESS usingn JCO Client java program.
Please suggest me some java API to read the calender information stored in outlook.
