  • How to group a database write and spreadsheet write in single "transaction"

    - by WhyGeeEx
    I have a Java program that writes results to both a DB (SQL Server) and a spreadsheet (POI), and it would be best if neither is written to if there's an error with either. It would be a lot worse if the spreadsheet was produced and then an error happened while saving to the DB, so I'm doing the DB-write first. Even so, I'm wondering if someone knows of a way to guarantee they both succeed or fail as a unit. Thanks!

  • No Secure Random Number Generators Available in JDK

    - by rwbutler
    Hi, I am currently running JDK 6 on Windows 7 and have installed the Unlimited Strength Policy Files. I wrote a Java app some time ago which used to work but now fails, giving an error message indicating that the SHA1PRNG SecureRandom is not available. I have tried printing a list of cryptographic providers available on the platform and it would appear that there are no secure random number generators available - does anyone have any idea why this might be? Many thanks in advance for your help!

    - by Dhana
    Hi, I'm new to Java Annotation. I know how to create custom annotation but I don't know how to process that Annotation to generate the dynamic code just like ejb 3.0 and hibernate does. I read some articles based on APT but no one gives the details about how to process the Annotation. Are there any tutorials with sample code for processing custom Annotations? Thanks

  • Format date in String Template email

    - by Gearóid
    I'm creating an email using String Template but when I print out a date, it prints out the full date (eg. Wed Apr 28 10:51:37 BST 2010). I'd like to print it out in the format dd/mm/yyyy but don't know how to format this in the .st file. I can't modify the date individually (using java's simpleDateFormatter) because I iterate over a collection of objects with dates. Is there a way to format the date in the .st email template?

  • Categorize the approximate shape of an array of Points in 3D Space

    - by user1295133
    I have a set of points in 3d space and I want to be able to categorize the shape that best fits them - cube, sphere, cylinder, planar (flat) etc. I've looked at supervised/machine learning but since I need first generate a large training data set that's not really suitable. My dream solution would be a java library with a wonderful magical function something like : public enum ShapeType { CUBE, SPHERE, CYLINDER, PLANAR } public ShapeType CategorizeShapeFromPoints( 3DPoint[] points ) However, any and all help will be appreciated. Thanks

  • get Phone numbers from android phone

    - by Luca
    Hi! First of all i'm sorry for my english... I've a problem getting phone numbers from contacts. That's my code import android.app.ListActivity; import android.database.Cursor; import android.os.Bundle; import android.provider.ContactsContract; import android.widget.SimpleAdapter; import android.widget.Toast; import java.util.ArrayList; import java.util.HashMap; public class TestContacts extends ListActivity { private ArrayList<HashMap<String,String>> list = new ArrayList<HashMap<String,String>>(); private SimpleAdapter numbers; /** Called when the activity is first created. */ @Override public void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.contacts); numbers = new SimpleAdapter( this, list, R.layout.main_item_two_line_row, new String[] { "line1","line2" }, new int[] { R.id.text1, R.id.text2 } ); setListAdapter( numbers ); Cursor cursor = getContentResolver().query(ContactsContract.Contacts.CONTENT_URI, null, null, null, null); while (cursor.moveToNext()) { String contactId = cursor.getString(cursor.getColumnIndex( ContactsContract.Contacts._ID)); String hasPhone = cursor.getString(cursor.getColumnIndex( ContactsContract.Contacts.HAS_PHONE_NUMBER)); //check if the contact has a phone number if (Boolean.parseBoolean(hasPhone)) { Cursor phones = getContentResolver().query( ContactsContract.CommonDataKinds.Phone.CONTENT_URI, null, ContactsContract.CommonDataKinds.Phone.CONTACT_ID +" = "+ contactId, null, null); while (phones.moveToNext()) { // Get the phone number!? String contactName = phones.getString( phones.getColumnIndex( ContactsContract.CommonDataKinds.Phone.DISPLAY_NAME)); String phoneNumber = phones.getString( phones.getColumnIndex( ContactsContract.CommonDataKinds.Phone.NUMBER)); Toast.makeText(this, phoneNumber, Toast.LENGTH_LONG).show(); drawContact(contactName, phoneNumber); } phones.close(); } }cursor.close(); } private void drawContact(String name, String number){ HashMap<String,String> item = new HashMap<String,String>(); item.put( "line1",name); item.put( "line2",number); list.add( item ); numbers.notifyDataSetChanged(); } } It'seems that no contact have a phone number (i've added 2 contacts on the emulator and i've tried also on my HTC Desire). The problem is that if (Boolean.parseBoolean(hasPhone)) returns always false.. How can i get correctly phone numbers? I've tried to call drawContact(String name, String number) before the if statement without querying for the phone number, and it worked (it draws two times the name). but on the LinearLayout they are not ordered alphabetically... how can i order alphabetically (similar to the original contacts app)? thank you in advice, Luca
