• 2-legged OAuth and the Gmail atom feed

  - by jdcotter

  We're trying to get 2-legged OAuth to work with the Gmail atom feed. We're using the Java library contributed by John Kristian, Praveen Alavilli and Dirk Balfanz. [http://oauth.net/code/] instead of the GData library. We know we have the correct CONSUMER_KEY and CONSUMER_SECRET, etc. becuase it works with the Contacts feed (http://www.google.com/m8/feeds/contacts/default/full) and have no problems. However with Gmail atom feed it always returns: HTTP/1.1 401 Unauthorized Any ideas? Should we try a different OAuth framework or does the problem lie on the Google side?

• Freemarker/Velocity - date manipulation

  - by Razor

  Hello, I have a fairly simple question about these 2 templating engines. I'm trying to make a future/paste date, a fixed time from now, e.g. 18 months ago, or tomorrow. I know that it is possible to do this with a java date object inside a velocity/freemarker template (something like $date.add(2,-18)), but I would like to do this with DateTool or freemarker core. This is something that I see as purely presentational (just think at the default dates you see in flight booking forms), so I can't see any reason why a templating engine shouldn't be able to do this. Is it possible though? If so, how?

• Hibernate Schema Validation Fails on Oracle Table Synonyms

  - by Rob

  I'm developing a Java web application that uses Hibernate (annotations-based) for persisting entities to an Oracle 11g database. The DBA created synonyms for the tables and requested that I use these synonyms instead of the physical tables. (Eg: Table "Foo" has synonym "S_Foo") If I have "hibernate.hbm2ddl.auto=validate" enabled, then the application fails on startup with "Missing Table: S_Foo". If I turn off the validation, then the app starts up fine and works properly. My guess is that Hibernate only checks against physical tables and not synonyms when validating that a table exists. Is there any way to enable Hibernate schema validation with synonyms? Can I specify both a physical table and a synonym in the annotation? I prefer having that extra safety check that the table structure is correct when the application starts up.

• smartGWT: ListGrid setDataSource on a servlet

  - by itit

  I want to setDataSource of my ListGrid on response received from my java servlet.

• Eclipse Could not Delete error

  - by KáGé

  Hello I'm working on a project with Eclipse and by now everything was fine, but last time I've tried building it, it returned the error "The project was not built due to "Could not delete '/Torpedo/bin/bin'.". Fix the problem, then try refreshing this project and building it since it may be inconsistent Torpedo Unknown Java Problem" and it deleted my bin folder which stores all the images and stuff needed for the program. (Fortunately I had a backup). I've tried googling it and tried every solution I found, but nothing helped, and also most of them suggests to delete the folder by hand, which I can't. What should I do? Thanks.

• Upload multiple Images and Ping an address to upload them

  - by azz0r

  Hello! I am trying to allow administrators to upload 20-30 images in one go. I have tried jquery uploadify, SWFUpload and other various jquery scripts. However I have had many issues doing this. Uploadify worked fine, however it stopped working and after a day of debugging I couldn't figure out why (and by god, I tried to figure out why) So I have decided to try a java applet, however they all seem to cost quite abit of money. All I need is something to select some images, then each image upload pings and address where I can resize them in PHP, and done. Does anyone know a freeware solution thats easy to use?

• How to use Blazeds with a custom classloader?

  - by festerwim

  Hi, has anybody tried using a custom classloader with BlazeDS? We have a web application using BlazeDS and we can convert Java objects in to ActionScript object and back without problems in the main application. However, we also have a plug-in mechanism based on a custom classloader. BlazeDS cannot map the types contained in jar files of that custom classloader since I don't know how to tell it to BlazeDS. Has anybody already done this? The livedocs of TypeMarshallingcontext show a setClassloader() method, but since the context seems to be a singleton, I assume this will not work if you have multiple custom classloaders (we have 1 for each plugin that is deployed) regards, Wim

• Building Eclipse RCP application, running fails

  - by Raven

  Hi, after successfully building my application the start fails because it relies on config files which are located in the META-INF directory and after the build this directory is zipped into a jar file, hence making it unable to access the config files. After manually unzipping the jar, deleting the jar and renaming the directory with xxx.jar the program runs without a problem. The config files are needed for SSO login (Kerberos). Here is the code: Bundle bundle = Platform.getBundle(Application.PLUGIN_ID); String path; try { path = new URL(bundle.getLocation().substring(18)).getPath(); } catch (MalformedURLException e1) { System.out.println(e1); path=""; } System.setProperty("java.security.auth.login.config",path+"META-INF/jaas-win.config"); Path variable contains something like "plugin/mydomain.pluginame-xxxx.jar/" But it seems that the System needs the jar unzipped. That am I doing wrong building the app? Thanks

• AJAX get data from large HTML page as the large HTML page loads

  - by Ed

  Not entirely sure whether this has a name but basically I have a large HTML page that is generated from results in a db. So viewing the HTML page (which is a report) in a browser directly does not display all contents immediately but displays what it has and additional HTML is added as the results from the DB are retrieved... Is there a way I can make an AJAX request to this HTML page and as opposed to waiting until the whole page (report) is ready, I can start processing the response as the HTML report is loaded? Or is there another way of doing it? Atm I make my AJAX response it just sits there for a minute or two until the HTML page is complete... If context is of any use: The HTML report is generated by a Java servlet and the page making the AJAX call is a JSP page. Unfortunately I can't very easily break the report up because it is generated by BIRT (Eclipse reporting extension). Thanks in advance.

• Hows does Seam injection work in Ejb3

  - by kazanaki

  Hello We are using Seam 2.2.0 Java 1.6.14 Weblogic 10.3.1.0 (named 11g Doh!) I have looked at Seam reference Seam in action These web pages However I still do not understand how to inject an EJB3 bean into a JSF backing bean. It seems to me that I have to (correct me if I am wrong) Annotate with @Name my backing bean Annotate with @Name my EJB3 bean Use the @In annotation in the backing bean Put an empty seam.properties file in the WAR that contains the backing bean Put an empty seam.properties file in the JAR that contains the EJB Set up a Seam interceptor in ejb-jar.xml of the EJB Don't I need to setup some JNDI URL somewhere? How exactly does Seam will find the EJB? The interceptor is enough? Also this means that I have to add a seam dependency in my EJB archive (because of the @Name annotation). So the web layer (Seam) "spills" into my business logic (EJB). Is this the recommended approach? Am I missing something here?

• Detect Applet context (am I inside an applet?)

  - by 7macaw

  Hi, I'm wondering if there's a way for a Java class to figure out if it is being used within an applet? That is, I have a library (a .jar file) that can be used by 3rd-party applications and applets. It does work within applets, but I'd like to do some things differently, depending on whether or not the library is used in an applet - like show applet-applicable errors, avoid local file I/O, etc. It would be nice if, say, Applet.getAppletContext() was static so that I could call it (and get NULL or not NULL) even if I don't have an applet instance, but alas, it isn't. Is there any other way?

• LWJGL not working

  - by Jesse Welch

  I'm working on a homework assignment to modify code given by my professor using LightWeight Java Game Library. The problem is that I can't fully load the test code to begin testing modifications. I've linked against the jar file as it says to in the modifications, but I still have one lingering error. The import statement import org.lwjgl.util.glu.*; Cannot be resolved, so I have errors on the following lines, spread throughout the code: textures[0] = GLApp.makeTexture("green.bmp"); GLU.gluPerspective(45.0f, (float)Display.getDisplayMode().getWidth() / (float)Display.getDisplayMode().getHeight(), 0.1f, 100.0f); GLU.gluLookAt(cameraX, cameraY, cameraZ, lookX, lookY, lookZ, 0.0f, 1.0f, 0.0f);` Any ideas on what is going wrong?

• robocode engine: how to design (write) the runtime engine -- the robot world

  - by Bob

  IBM has (had) a free learn-Java program called RoboCode, in which custom robots could be written that would then do battle in a 2D space. I would like to write the environment that supports such robots, but don't know what pattern or design to use. Each robot is a thread. Each thread is given a certain (indeterminate) amount of run-time by the JRE. A robot world engine would start by building a list of the players/robots, then enter a loop that allows each player in turn to do whatever it likes: move forward, turn left, fire toward the northwest corner, whatever. Each robot is also informed of events of interest: an enemy or several enemies are within range, it has been hit by a bullet, etc. The combination of handling threads that are also event listeners (are they also producers?) confuses me; it seems that there's more to the game engine. Even some general ideas would help. TIA.

• J2ME VS Android VS iPhone VS Symbian VS Windows CE

  - by Sadi

  I have very little idea about mobile platform, though I am interested to program for mobile platform. Would you please compare between J2ME VS Android VS iPhone VS Symbian VS Windows CE. I would like to know which one is better, and if there is any VM technology to test the programs. Which one should I choose and why? Is there any IDE, debugging facilities? Personally I would like to code for open source, but any suggestion are welcome. I have preliminary knowledge on java. I would also like to know, if there is anything else that you can recommended. Thank you

• JPQL get most recent rows

  - by Vinnie

  Let's say I have the following tables my_profile_data ------------- integer: profile_id date: date_changed string: value my_profile ------------- integer: profile_id string: name I want to get the most recent profile information. In plain SQL this would look something like: select mpd.profile_id, mpd.value, max(mpd.date_changed) from my_profile_data mpd, my_profile mp where mpd.profile_id = mp.profile_id and mp.name='The Profile I Want' group by mpd.profile_id I've tried different variants of the following JPQL query, but cant get it to work. SELECT mpd FROM MyProfileData mpd LEFT JOIN (SELECT mpd.profileId profileId, MAX(mpd.dateChanged) FROM MyProfileData mpd LEFT JOIN mp.profile WHERE mp.name = :name GROUP BY mpd.profileId) recent ON (rp.profileid = recent.profileId) Is this query doable in JPA? I'm using EclipseLink as my JPA provider. The innermost exception I get when I try to run this is Caused by: NoViableAltException(81!=[506:7: (n= joinAssociationPathExpression ( AS )? i= IDENT | t= FETCH n= joinAssociationPathExpression )]) at org.eclipse.persistence.internal.jpa.parsing.jpql.antlr.JPQLParser.join(JPQLParser.java:3669) ... 73 more

• How to do this GQL query in JDO

  - by TheDon

  I have about 50k entities stored in appengine. I am able to look up an individual record via the GQL admin interface with a query like: SELECT * FROM Pet where __key__ = KEY( 'Pet','Fido') But I'm having trouble figuring out how to do a batch version of this via JDO. Right now I have this: PersistenceManager pm = ...; for(Pet pet : pets) { for(String k : getAllAliases(pet)) { keys.add(KeyFactory.createKeyString(Pet.class.getSimpleName(), k)); } } Query q = pm.newQuery("select from " + Pet.class.getName() + " where id == :keys"); List<Pet> petlist = (List<Pet>) q.execute(keys); But though 'Fido' works in the GQL case, it returns nothing when I use that Java + JDO code. What am I doing wrong?

• NoSuchMethodError with Spring MutableValues

  Hello experts! I have written a test where i specify my application context location with annotations. I then autowire my dao into the test. @ContextConfiguration(locations = {"file:service/src/main/webapp/WEB-INF/applicationContext.xml"}) public class MyTest extends AbstractTestNGSpringContextTests { @Autowired protected MyDao myDao; private PlatformTransactionManager transactionManager; private TransactionTemplate transactionTemplate; @Test public void shouldSaveEntityToDb() { transactionTemplate.execute(new TransactionCallbackWithoutResult() { protected void doInTransactionWithoutResult(TransactionStatus status) { Entity entity = new Entity(); //test myDao.save(entity) //assert assertNotNull(entity.getId()); } }); } When i run the test i get an exception which states that the application context could not be loaded and it boils down to: Caused by: java.lang.NoSuchMethodError: org.springframework.beans.MutablePropertyValues.add(Ljava/lang/String;Ljava/lang/Object;)Lorg/springframework/beans/MutablePropertyValues; I have no idea where to start looking, why do i get this error and how can i resolve it?

• Implementing a Patricia Trie for use as a dictionary

  - by Regis Frey

  I'm attempting to implement a Patricia Trie with the methods addWord(), isWord(), and isPrefix() as a means to store a large dictionary of words for quick retrieval (including prefix search). I've read up on the concepts but they just aren't clarifying into an implementation. I want to know (in Java or Python code) how to implement the Trie, particularly the nodes (or should I implement it recursively). I saw one person who implemented it with an array of 26 child nodes set to null/None. Is there a better strategy (such as treating the letters as bits) and how would you implement it?

• Android compatibility with Restlet/JSON/Jackson

  - by Cookie

  Hi there, I'm currently working on a webservice-client for Android. I'm using a Java client library which provides an abstraction for interaction with the service. The client library works on normal machines. However, when I use the classes in my Android project, some calls don't return a result on Android, the background-service stops working at the first of those commands. Wireshark shows a tcp exchange, the server gets the requests. There is no exceptions or anything. Something in the serialization/deserialization semms not to work. I'm using the newest version of Jackson libraries (1.5.3) and the restlet jar in the android edition. Is there any known problems with Jackson and Android? Which code and libraries are compatible with Android? Thanks in advance.

• Where is the displaytag of scheduled reporting?

  - by Nathan Feger

  So I have been making some reports and using displaytag to output these reports in html, csv, excel, pdf, etc. They are paginated, and take a simple object graph... and output excellent results everytime, with very little code. However, I need to use displaytag or its equivalent outside of a jsp. So that a user can schedule a report to run, and that report is stored in a db, or emailed for later viewing. I have looked at jasper-based reporting solutions, but making a jasper jrxml file is just a nightmare. I know there are gui tools to help, but I'm content with the simple output of displaytable, so I'm happy to give up that control for ease of implementation. Really, if I could take the display:table config out of the jsp I would, so please keep that in mind when proposing a solution. btw, java solutions would be my cup of tea.

• Throwing a new exception while throwing an old exception

  - by FredOverflow

  If a destructor throws in C++ during stack unwinding caused by an exception, the program terminates. (That's why destructors should never throw in C++.) If a finally block is entered in Java because of an exception in the corresponding try block and that finally block throws another exception, the first exception is silently swallowed. This question crossed my mind: Could a programming language handle multiple exceptions being thrown at the same time? Would that be useful? Have you ever missed that ability? Is there a language that already supports this? Is there any experience with such an approach? Any thoughts?
