  • How to implement SAML SSO

    - by A_M
    How is SAML SSO typically implemented? I've read this about using SAML with Google Apps, and the wikipedia entry on SAML. The wikipedia entry talks about responding with forms containing details of the SAMLRequest and SAMLResponse. Does this mean that the user has to physically submit the form in order to proceed with the single sign on? The google entry talks about using redirects, which seems more seemless to me. However, it also talks about using a form for the response which the user must submit (although it does talk about using JavaScript to automatically submit the form). Is this the standard way of doing this? Using redirects and JavaScript for form submission? Does anyone know of any other good resources about how to go about implementing SSO between a Windows Domain and a J2EE web application. The web application is on a separate network/domain. My client wants to use CA Siteminder (with SAML).

  • How to get contacts in order of they upcoming birthdays?

    - by Pentium10
    I have code to read contacts details and to read birthday. But how do I get a list of contacts in order of they upcoming birthday? For a single contact identified by id I get details and birthday like this. Cursor c = null; try { Uri uri = ContentUris.withAppendedId( ContactsContract.Contacts.CONTENT_URI, id); c = ctx.getContentResolver().query(uri, null, null, null, null); if (c != null) { if (c.moveToFirst()) { DatabaseUtils.cursorRowToContentValues(c, data); } } c.close(); // read birthday c = ctx.getContentResolver() .query( Data.CONTENT_URI, new String[] { Event.DATA }, Data.CONTACT_ID + "=" + id + " AND " + Data.MIMETYPE + "= '" + Event.CONTENT_ITEM_TYPE + "' AND " + Event.TYPE + "=" + Event.TYPE_BIRTHDAY, null, Data.DISPLAY_NAME); if (c != null) { try { if (c.moveToFirst()) { this.setBirthday(c.getString(0)); } } finally { c.close(); } } return super.load(id); } catch (Exception e) { Log.v(TAG(), e.getMessage(), e); e.printStackTrace(); return false; } finally { if (c != null) c.close(); }

  • Biggest GWT Pitfalls?

    - by agartzke
    I'm at the beginning/middle of a project that we chose to implement using GWT. Has anyone encountered any major pitfalls in using GWT (and GWT-EXT) that were unable to be overcome? How about from a performance perspective? A couple things that we've seen/heard already include: Google not being able to index content CSS and styling in general seems to be a bit flaky Looking for any additional feedback on these items as well. Thanks!

  • JPA merge fails due to duplicate key

    - by wobblycogs
    I have a simple entity, Code, that I need to persist to a MySQL database. public class Code implements Serializable { @Id private String key; private String description; ...getters and setters... } The user supplies a file full of key, description pairs which I read, convert to Code objects and then insert in a single transaction using em.merge(code). The file will generally have duplicate entries which I deal with by first adding them to a map keyed on the key field as I read them in. A problem arises though when keys differ only by case (for example: XYZ and XyZ). My map will, of course, contain both entries but during the merge process MySQL sees the two keys as being the same and the call to merge fails with a MySQLIntegrityConstraintViolationException. I could easily fix this by uppercasing the keys as I read them in but I'd like to understand exactly what is going wrong. The conclusion I have come to is that JPA considers XYZ and XyZ to be different keys but MySQL considers them to be the same. As such when JPA checks its list of known keys (or does whatever it does to determine whether it needs to perform an insert or update) it fails to find the previous insert and issuing another which then fails. Is this corrent? Is there anyway round this other than better filtering the client data? I haven't defined .equals or .hashCode on the Code class so perhaps this is the problem.

  • filling array gradually with data from user

    - by neville
    I'm trying to fill an array with words inputted by user. Each word must be one letter longer than previous and one letter shorter than next one. Their length is equal to table row index, counting from 2. Words will finally create a one sided pyramid, like : A AB ABC ABCD Scanner sc = new Scanner(System.in); System.out.println("Give the height of array: "); String[] words = new String[height]; for(int i=2; i<height+2; i++){ System.out.println("Give word with "+i+" letters."); words[i-2] = sc.next(); while( words[i-2].length()>i-2 || words[i-2].length()<words[i-3].length() ){ words[i-2] = sc.next(); } } Currently the while loop doesn't influence scanner at all :/

  • How to get roles with JSR 196 authentification in GlassFish?

    - by deamon
    I want to use a custom authentication module conforming to JSR 196 in GlassFish 3. The interface javax.security.auth.message.ServerAuth has the method: AuthStatus validateRequest( MessageInfo messageInfo, javax.security.auth.Subject clientSubject, javax.security.auth.Subject serviceSubject ) AuthStatus can be one of several constants like FAILURE or SUCCESS. The question is: How can I get the roles from a "role datebase" with JSR 196? Example: The server receives a request with a SSO token (CAS token for example), checks whether the token is valid, populates the remote user object with roles fetches from a database via JDBC or from REST service via http. Is the role fetching in the scope of JSR 196? How could that be implemented? Do I have to use JSR 196 together with JSR 115 to use custom authentication and a custom role source?

  • game speed problem

    HI..I made a little game.But this game works on every computer with different speed.I think it is about resolution.I used every thing in paintcomponent.and If I change screen size the game goes slower or faster.And if i run this game on another computer wich has different resolution it also works different.

  • Get from Android BroadcastReciever to a UI

    - by Andy
    I have a reciever that works well, but I can't seem to show a proper UI, although the toast appears correctly. As far as I can tell, this is caused by Android requiring the class to extend Activity, however, the class already extends BroadcastReciever, so I can't do this. So, I tried to do an Intent, but this failed too. There are no errors, but the screen doesn't show. Source code is below, and any help would be most appreciated. Reciever public class Reciever extends BroadcastReceiver { @Override public void onReceive(Context context, Intent intent) { Toast.makeText(context, "Alarm Recieved", Toast.LENGTH_LONG).show(); Intent i = new Intent(); i.setClass(context, AlarmRing.class); } } AlarmRing public class AlarmRing extends Activity { /** Called when the activity is first created. */ @Override public void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.alarm); MediaPlayer mp = MediaPlayer.create(getBaseContext(), R.raw.sweetchild); mp.start(); } Manifest <?xml version="1.0" encoding="utf-8"?> <manifest xmlns:android="http://schemas.android.com/apk/res/android" package="com.comaad.andyroidalarm" android:versionCode="1" android:versionName="1.0"> <application android:icon="@drawable/icon" android:label="@string/app_name"> <activity android:name=".AndyRoidAlarm" android:label="@string/app_name"> <intent-filter> <action android:name="android.intent.action.MAIN" /> <category android:name="android.intent.category.LAUNCHER" /> </intent-filter> </activity> <receiver android:name="com.comaad.andyroidalarm.Reciever" android:enabled="true"> <intent-filter> <action android:name="com.comaad.andyroidalarm.Reciever"></action> </intent-filter> </receiver> <activity android:name=".AlarmRing"></activity> </application> </manifest> }

  • FindBugs controversal description

    - by Tom Brito
    Am I understanding it wrong, or is the description wrong? Equals checks for noncompatible operand (EQ_CHECK_FOR_OPERAND_NOT_COMPATIBLE_WITH_THIS) This equals method is checking to see if the argument is some incompatible type (i.e., a class that is neither a supertype nor subtype of the class that defines the equals method). For example, the Foo class might have an equals method that looks like: public boolean equals(Object o) { if (o instanceof Foo) return name.equals(((Foo)o).name); else if (o instanceof String) return name.equals(o); else return false; This is considered bad practice, as it makes it very hard to implement an equals method that is symmetric and transitive. Without those properties, very unexpected behavoirs are possible. From: http://findbugs.sourceforge.net/bugDescriptions.html#EQ_CHECK_FOR_OPERAND_NOT_COMPATIBLE_WITH_THIS The description says that the Foo class might have an aquals method like that, and after it says that "This is considered bad practice". I'm not getting the "right way".. How should the following method be to be right? @Override public boolean equals(Object obj) { if (obj instanceof DefaultTableModel) return model.equals((DefaultTableModel)obj); else return false; }

  • EJB3 Transaction Propogation

    - by Matt S.
    I have a stateless bean something like: @Stateless public class MyStatelessBean implements MyStatelessLocal, MyStatelessRemote { @PersistenceContext(unitName="myPC") private EntityManager mgr; @TransationAttribute(TransactionAttributeType.SUPPORTED) public void processObjects(List<Object> objs) { // this method just processes the data; no need for a transaction for(Object obj : objs) { this.process(obj); } } @TransationAttribute(TransactionAttributeType.REQUIRES_NEW) public void process(Object obj) { // do some work with obj that must be in the scope of a transaction this.mgr.merge(obj); // ... this.mgr.merge(obj); // ... this.mgr.flush(); } } The typically usage then is the client would call processObjects(...), which doesn't actually interact with the entity manager. It does what it needs to do and calls process(...) individually for each object to process. The duration of process(...) is relatively short, but processObjects(...) could take a very long time to run through everything. Therefore I don't want it to maintain an open transaction. I do need the individual process(...) operations to operate within their own transaction. This should be a new transaction for every call. Lastly I'd like to keep the option open for the client to call process(...) directly. I've tried a number of different transaction types: never, not supported, supported (on processObjects) and required, requires new (on process) but I get TransactionRequiredException every time merge() is called. I've been able to make it work by splitting up the methods into two different beans: @Stateless @TransationAttribute(TransactionAttributeType.NOT_SUPPORTED) public class MyStatelessBean1 implements MyStatelessLocal1, MyStatelessRemote1 { @EJB private MyStatelessBean2 myBean2; public void processObjects(List<Object> objs) { // this method just processes the data; no need for a transaction for(Object obj : objs) { this.myBean2.process(obj); } } } @Stateless public class MyStatelessBean2 implements MyStatelessLocal2, MyStatelessRemote2 { @PersistenceContext(unitName="myPC") private EntityManager mgr; @TransationAttribute(TransactionAttributeType.REQUIRES_NEW) public void process(Object obj) { // do some work with obj that must be in the scope of a transaction this.mgr.merge(obj); // ... this.mgr.merge(obj); // ... this.mgr.flush(); } } but I'm still curious if it's possible to accomplish this in one class. It looks to me like the transaction manager only operates at the bean level, even when individual methods are given more specific annotations. So if I mark one method in a way to prevent the transaction from starting calling other methods within that same instance will also not create a transaction, no matter how they're marked? I'm using JBoss Application Server 4.2.1.GA, but non-specific answers are welcome / preferred.

  • Exclude filter from certain url's

    - by Mads Mobæk
    I'm using a filter in web.xml to check if a user is logged in or not: <filter> <filter-name>LoginFilter</filter-name> <filter-class>com.mycompany.LoginFilter</filter-class> </filter> <filter-mapping> <filter-name>LoginFilter</filter-name> <url-pattern>/*</url-pattern> </filter-mapping> And this works like a charm until I have a stylesheet or image I want to exclude from this filter. I know one approach is to put everything that's protected inside /privateor similar, and then set the url-pattern to: <url-pattern>/private/*</url-pattern>. The downside to this is my URLs now looking like: http://www.mycompany.com/private/mypage instead of http://www.mycompany.com/mypage. Is there another solution to this problem, that let me keep my pretty-urls?

  • Jackson object mapping - map incoming JSON field to protected property in base class

    - by Pete
    We use Jersey/Jackson for our REST application. Incoming JSON strings get mapped to the @Entity objects in the backend by Jackson to be persisted. The problem arises from the base class that we use for all entities. It has a protected id property, which we want to exchange via REST as well so that when we send an object that has dependencies, hibernate will automatically fetch these dependencies by their ids. Howevery, Jackson does not access the setter, even if we override it in the subclass to be public. We also tried using @JsonSetter but to no avail. Probably Jackson just looks at the base class and sees ID is not accessible so it skips setting it... @MappedSuperclass public abstract class AbstractPersistable<PK extends Serializable> implements Persistable<PK> { @Id @GeneratedValue(strategy = GenerationType.AUTO) private PK id; public PK getId() { return id; } protected void setId(final PK id) { this.id = id; } Subclasses: public class A extends AbstractPersistable<Long> { private String name; } public class B extends AbstractPersistable<Long> { private A a; private int value; // getter, setter // make base class setter accessible @Override @JsonSetter("id") public void setId(Long id) { super.setId(id); } } Now if there are some As in our database and we want to create a new B via the REST resource: @POST @Consumes(MediaType.APPLICATION_JSON) @Produces(MediaType.APPLICATION_JSON) @Transactional public Response create(B b) { if (b.getA().getId() == null) cry(); } with a JSON String like this {"a":{"id":"1","name":"foo"},"value":"123"}. The incoming B will have the A reference but without an ID. Is there any way to tell Jackson to either ignore the base class setter or tell it to use the subclass setter instead? I've just found out about @JsonTypeInfo but I'm not sure this is what I need or how to use it. Thanks for any help!

  • Data Structure Behind Amazon S3s Keys (Filtering Data Structure)

    - by dimo414
    I'd like to implement a data structure similar to the lookup functionality of Amazon S3. For those of you who don't know what I'm taking about, Amazon S3 stores all files at the root, but allows you to look up groups of files by common prefixes in their names, therefore replicating the power of a directory tree without the complexity of it. The catch is, both lookup and filter operations are O(1) (or close enough that even on very large buckets - S3's disk equivalents - both operations might as well be O(1))). So in short, I'm looking for a data structure that functions like a hash map, with the added benefit of efficient (at the very least not O(n)) filtering. The best I can come up with is extending HashMap so that it also contains a (sorted) list of contents, and doing a binary search for the range that matches the prefix, and returning that set. This seems slow to me, but I can't think of any other way to do it. Does anyone know either how Amazon does it, or a better way to implement this data structure?

  • Rails Autocompletion Issue - Rails 1.2.3 to 2.3.5

    - by Grant Sayer
    I have an issue with rails Autocompletion from some code that i've inherited from an old Rails 1.2.3 project that I'm porting to Rails 2.3.5. The issue revolves around javascript execution within the auto_complete helper :after_update_element. The scenario is: A user is presented with a popup form with a number of fields. In the first field as they enter text the auto_complete AJAX call occurs, returning a result, plus a series of other HTML data wrapped in <divs> so that the after_update_element call can iterate over the other data and fill in the remaining fields. The issue lies with the extraction of the other fields which works on IE, fails on Firefox. Here is the code: <%= text_field_with_auto_complete :item, :product_code, {:value => ""}, {:size => 40, :class => "input-text", :tabindex => 6, :select => 'code', :with => "element.name + '=' + escape(element.value) + '&supplier_id=' + $('item_supplier_id').value", :after_update_element => "function (ele, value) { $('item_supplier_id').value = Utilities.extract_value(value, 'supplier_id'); $('item_supplied_size').value = Utilities.extract_value(value, 'size')}"}%> Now the function Utilities is designed to grab the fields from the string of values and looks like: // // Extract a particular set of data from the autocomplete actions // Utilities.extract_value = function (value, className) { var result; var elements = document.getElementsByClassName(className, value); if (elements && elements.length == 1) { result = elements[0].innerHTML.unescapeHTML(); } return result; }; In Firefox the value of result is undefined

    I'm starting down the road of Android Development. At this point I'm looking for some insight from other developers who have been doing 'droid development and have some experience to share with someone who is just starting out. This can be anything from API to AVM to IDE. Any unexpected things come up while building your apps? Any tips for project layout or organization that help facilitate the deployment process to the Android AppStore? Any patterns which specifically helped in a particular situation? Even links to great blogs or sample apps and resources beyond those which you can grab from Google Code would be appreciated.

  • ListView items not responding to tap

    - by Justin Williams
    I'm just getting my feet wet with Android and have built a UI that contains a TabHost with three tabs. Each tab is powered by its own Activity. The first Tab contains a listview with a prepopulated set of rows and is built from a custom ArrayAdapter. The problem I'm running into is that none of the ListView rows are tappable. In other words, when I tap on them there is no orange selection. If I use the scroll ball on my Nexus One it will select, but any touch gestures don't seem to be responding. All the UI is being handled using XML files with a main.xml housing the TabHost - LinearLayout - TabWidget/FrameLayout and a nearby_activity.xml file containing my ListView UI <?xml version="1.0" encoding="utf-8"?> <LinearLayout xmlns:android="http://schemas.android.com/apk/res/android" android:orientation="vertical" android:layout_width="fill_parent" android:layout_height="fill_parent"> <TextView android:id="@+id/android:empty" android:layout_width="fill_parent" android:layout_height="fill_parent" android:text="@string/nearby_no_events" /> <ListView android:id="@android:id/list" android:layout_width="fill_parent" android:layout_height="0dip" android:layout_weight="1.0" android:choiceMode="multipleChoice" android:divider="#d9d9d9" android:dividerHeight="1px" android:cacheColorHint="#eee" /> </LinearLayout> And the relevant code from my Activity that is set to show in the selected tab. public class NearbyActivity extends ListActivity { private ArrayList<Event> m_events = null; private EventAdapter m_adapter = null; public void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.nearby_activity); getEvents(); this.m_adapter = new EventAdapter(this, R.layout.eventrow, m_events); setListAdapter(this.m_adapter); } private void getEvents() { m_events = new ArrayList<Event>(); for (int i = 0; i < 100 ; i++) { Event e = new Event(); e.setEventName("Event " + i); e.setVenueName("Staples Center"); e.setStartDate(new Date()); m_events.add(e); } } private class EventAdapter extends ArrayAdapter<Event> { private ArrayList<Event> items; public EventAdapter(Context context, int textViewResourceId, ArrayList<Event> items) { super(context, textViewResourceId, items); this.items = items; } @Override public View getView (int position, View convertView, ViewGroup parent) { View v = convertView; if (v == null) { LayoutInflater vi = (LayoutInflater)getSystemService(Context.LAYOUT_INFLATER_SERVICE); v = vi.inflate(R.layout.eventrow, null); } Event e = items.get(position); if (e != null) { TextView nameText = (TextView)v.findViewById(R.id.eventName); TextView venueNameText = (TextView)v.findViewById(R.id.venueName); if (nameText != null) { nameText.setText(e.getEventName()); } if(venueNameText != null) { venueNameText.setText(e.getVenueName()); } } return v; } } } My listview row's are populated by an XML file as well. <?xml version="1.0" encoding="utf-8"?> <RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android" android:layout_width="fill_parent" android:layout_height="?android:attr/listPreferredItemHeight" android:orientation="vertical" android:padding="4dip"> <TextView android:id="@+id/eventName" android:layout_width="fill_parent" android:layout_height="wrap_content" android:layout_alignParentTop="true" android:inputType="text" android:singleLine="true" android:ellipsize="marquee" android:textSize="18sp" android:textColor="#000" /> <TextView android:id="@+id/venueName" android:layout_width="wrap_content" android:layout_height="wrap_content" android:layout_below="@id/eventName" android:layout_alignParentBottom="true" android:layout_marginRight="55dip" android:singleLine="true" android:ellipsize="end" android:scrollHorizontally="true" android:textSize="13sp" android:textColor="#313131" android:layout_alignWithParentIfMissing="true" android:gravity="center_vertical" /> </RelativeLayout> Thanks for any help you can offer.

  • Message Queue or Scheduler

    - by Walter White
    Hi all, I am currently using Quartz Scheduler for asynchronous tasks such as sending an email when an exception occurs, sending an email from the web interface, or periodically analyzing traffic. Should I use a message queue for sending an email? Is it any more efficient or correct to do it that way? The scheduler approach works just fine. If I use a queue and the email failed to send, is it possible for the queue to retry sending the email at a later time? The queue approach looks simpler than the scheduler for tasks that need to happen immediately, but for scheduler tasks, the scheduler still, unless there is more to the queue than I am aware of. I have not yet used JMS, so this is what I have read. Walter

  • How to get contacts in order of their upcoming birthdays?

    - by Pentium10
    I have code to read contact details and to read birthdays. But how do I get a list of contacts in order of their upcoming birthday? For a single contact identified by id, I get details and birthday like this: Cursor c = null; try { Uri uri = ContentUris.withAppendedId( ContactsContract.Contacts.CONTENT_URI, id); c = ctx.getContentResolver().query(uri, null, null, null, null); if (c != null) { if (c.moveToFirst()) { DatabaseUtils.cursorRowToContentValues(c, data); } } c.close(); // read birthday c = ctx.getContentResolver() .query( Data.CONTENT_URI, new String[] { Event.DATA }, Data.CONTACT_ID + "=" + id + " AND " + Data.MIMETYPE + "= '" + Event.CONTENT_ITEM_TYPE + "' AND " + Event.TYPE + "=" + Event.TYPE_BIRTHDAY, null, Data.DISPLAY_NAME); if (c != null) { try { if (c.moveToFirst()) { this.setBirthday(c.getString(0)); } } finally { c.close(); } } return super.load(id); } catch (Exception e) { Log.v(TAG(), e.getMessage(), e); e.printStackTrace(); return false; } finally { if (c != null) c.close(); } and the code to read all contacts is: public Cursor getList() { // Get the base URI for the People table in the Contacts content // provider. Uri contacts = ContactsContract.Contacts.CONTENT_URI; // Make the query. ContentResolver cr = ctx.getContentResolver(); // Form an array specifying which columns to return. String[] projection = new String[] { ContactsContract.Contacts._ID, ContactsContract.Contacts.DISPLAY_NAME }; Cursor managedCursor = cr.query(contacts, projection, null, null, ContactsContract.Contacts.DISPLAY_NAME + " COLLATE LOCALIZED ASC"); return managedCursor; }
