How to retrieve JTable from JScrollPane?

In the main class MyReconcile which extends JFrame, I have codes as every body do
myContainer.add(myControlPane, Layout.North);
myTable = new JTable(dataValues, columnNames );
myPane = new JScrollPane(myTable);
myContainer.add(myPane, Layout.Center);
In another class MyControlPanel, I pass myContainer into this class and try to get that table object, finally I need its data. my code is
1. thePane = (JScrollPane) theContainer.getComponent(1);
2. theTable = (JTable) thePane.getComponent(0);
the result is that 1 is successful, but 2 failed.
Anybody could give help? Thanks!
Victor

I've never done this but you might try:
theTable = (JTable) thePane.getViewport().getView();

hi shanu,

pls have a look at the following code snippet.
public class XMLValidator {
static ArrayList strXXX = new ArrayList();
public void validate(){
factory.setValidating(true);
parser = factory.newSAXParser();
//all factory code is here only
parser.parse(xmlURI, new XMLErrorHandler());
public void setXXX(String pstrXXX){
strUpn.add(pstrXXX);
public ArrayList getXXX(){
return strXXX;
class XMLErrorHandler extends DefaultHandler {
String tagName = "";
String tagValue = "";
String applicationRefNo = "";
String XXXValue ="";
String XXXNo = "";
XMLValidator objXmlValidator = new XMLValidator();
public void startElement(String uri, String name, String qName, Attributes atts) {

How to retrieve info from a MacOs Standard floppy?

How can I retrieve information from a MacOs Standard formatted floppy disk on Snow Lion?
I have this collection of old floppy disks that were formatted as MacOs Standard format back in the days. They do hold some files which I'd like to backup on a backup drive.
But, Snow Lion does not read MacOs Standard formatted disks apparently.
So, does anyone know how to retrieve information from MacOs Standard formatted floppy disks?
Thank you!

This what I see in ML with my old SmartDisk VST (model# FDUSB-M) floppy drive:
Interesting observations:
1. I was able to add and remove files to the disk.
2. I was not able to erase the disk with Disk Utility. It returned an error.
3. Disk Utility did not offer the HFS+ format option, only FAT32 and ExFAT.
4. I could only find 1 floppy in my house so it could be partially defective.

How to retrieve photos from the iCloud

How to retrieve photos from the iCloud

icloud only stores photos in backups (or in a special case, when using photo stream). If you have turned on backup and made sure the camera roll is turned on (only photos from camera roll are backed up), then you can get photos back by performing a restore. But note that users should always sync photos to a computer to archive them, relying on icloud is not foolproof.
http://support.apple.com/kb/HT1766?viewlocale=en_US&locale=en_UShttp://www.ipadconverter-mac.com/restore-iphone-from-icloud/
Go to Settings>General>Reset and tap Erase All Content and Settings. This will erase your device. Then you will go through the setup screens again as you did when your device was new, and when given the option, select Restore from iCloud Backup.

How to retrieve data from inside the folders in SharePoint SSRS

Hi ,
How to get the data from inside the folders and subfolders.
How can I do that.
https://social.msdn.microsoft.com/Forums/en-US/15451351-4ee2-428c-a0b7-135810e4cbfa/action?threadDisplayName=ssrs-reports-sharepoint-list-datasource-how-to-retrieve-items-from-subfolders
Here the information is not given.
Regards
Vinod

Hi Vinodaggarwal87,
According to your description, you want to retrieve data from sharepoint list in a sub folder. Right?
In this scenario, we should select the XML data source type and in the connection string provide the
List.asmx service URL when creating data source. Then we need to use the List web Service and specify "recursive" for ViewAttribute in Lists.asmx. For detail steps, please refer to the links below:
Generate SSRS report on SharePoint List with folders using List Service.
SSRS: how to specify ViewAttributes when creating a report against a SharePoint's list
If you want to set the ViewAttribute on CAML query level. You need add the view tag outside of query tag:
<View Scope="RecursiveAll">
    <Query>
        <Where>...</Where>
    </Query>
</View>
Reference:
View Element (List)
ViewAttributes Recursive Scope not working SharePoint 2013 CAML Query to fetch all files from document library recursively
If you have any question, please feel free to ask.

Hi friends,
I have one question. i want to display values in the struts jsp file from the struts DAO class. can anyone tell how do it.
Appreciated for your help.
Thanks
G1 :)

Hi Santosh,
Thanks for your prompt reply.
Actually, my problem is i want to display complete rows from the DAO to JSP page. I'm displaying all the rows in the DAO from DB.
But i dont know how to retrieve all these data from DAO. Can i take arraylist.??
DAO:
------------     public Customers getData(Customers customers){ // Reading data from DB
     //ArrayList list = null ;
     try
          Connection conn = getSQLConnection();
          Statement statement = conn.createStatement();
          String qry = "select * from register";
          ResultSet resultSet = null;
          PreparedStatement pstat = conn.prepareStatement(qry);
          // pstat.setString(1, customers.getFname());
          resultSet = pstat.executeQuery();
//Print the data to the console
while(resultSet.next()){
          String fnam = resultSet.getString(1);
          String lnam = resultSet.getString(2);
          String gen = resultSet.getString(3);
          String addres = resultSet.getString(4);
          String cit = resultSet.getString(5);
          String zip = resultSet.getString(6);
          String county = resultSet.getString(7);
          String emal = resultSet.getString(8);
          System.out.println("First name:"+fnam);
          System.out.println("Last name:"+lnam);
          System.out.println("Address:"+addres);
          customers.setFname(fnam);
          customers.setLname(lnam);
          customers.setGender(gen);
          customers.setAddress(addres);
          customers.setCity(cit);
          customers.setZipcode(zip);
          customers.setCountry(county);
          customers.setEmail(emal);
               statement.close();
               conn.close();
          }catch(Exception e1){
               e1.printStackTrace();
          return customers;
Bean:

request.getSession().setAttribute("customers", customers);

I'm sorry this is just practicals. i'm not doin any real time project. that;s why i have placed all these code.
Thanks for your patience for resolving my problems.

How to retrieve photos from water-damaged iPhone

Last week (Wednesday), I my iPhone got wet while I was out of the country. I immediately put it in a grocery bag of rice (no ziplocks or tupperware available), and put it on top of the refrigerator. I left it there until the end of my trip on Saturday. When I got home, I put it on the charger and left it until the local AT&T store opened on Monday. They weren't able to help me, but suggested I go to the phone repair place across the street where, for $25, he opened it up and dried it out. It did not come back on for him, but he suggested that I take it home and put it on my charger and see if it will come back on.
Just to be clear, I am not all that worried about salvaging the phone. I'm pretty sure it is irretrievably damaged due to the length of time it was in the water and the fact that it was ON and I checked to see if it worked after 24 hours (that's how long they told me to keep it in rice). I have insurance and can replace the phone. Everything else was backed up. What I DO need, is to retrieve the work-related photos that are on the phone that did not get backed up while I was on my trip. I do not use the cloud, so 3 days worth of photos are on my phone (luckily I backed up before I left the country). I did some surfing and found some steps that say they can sometimes retrieve data from a wet/dead phone, so I tried to turn it on one more time, and was ecstatic to see the little Apple symbol appear followed by the "unlock" screen, but then the phone died again.
This gave me hope, so I ran back down to the repair shop and he could repeatedly get it to come on, but it shows the battery is dead and it will not stay on long enough to retrieve the data. He swapped the battery and got it to come on long enough to start the back up but it got about 1/2 way through before it shut itself off again. The battery in it is the original and it is dead. He suggested I plug it in and keep trying to get it to come on long enough to dowload the pictures. I have it plugged in, but it doesn't appear to be charging at all. Is there something more I can do? I've seen other posts that suggest keeping it in the rice for over a week. I've even seen software that says it can retrieve data even from a dead phone ("Wondershare Dr. Fone"). Is there anything I can do to get those pictures?
Thanks!

Search the internet. This is way beyond the scope of this forum.
Best of luck.
