Which is better? JDO or Java Persistance API?

Hi folks
I'm trying to build an app on Google's cloud service.
Looking into this ( [http://code.google.com/appengine/docs/java/overview.html|http://code.google.com/appengine/docs/java/overview.html]), it tells me that for java projects there are 2 possibilities for persistance - JDO , and Java Persistance. Does anyone have any advice on which is better and/or easier? Also, if anyone has a small example they could post, that would be very useful too.
this isn't exactly a JDBC question, and maybe this should be posted somewhere else? If so please tell me where I should be asking this question.
Thanks!
-Tom

I personally find Java Persistence to be easy to use and it works just fine.
I can't say if you would agree. You'll just have to judge that for yourself, which means: put some effort into trying it out. I'd start by not requesting small examples in a forum, but by actually looking for them yourself using your search engine of choice.

  • Which is better ? Toplink Java objects or Toplink Entities ?

    Hi
    We are planing to use Toplink JPA that comes with JDeveloper 11g preview release
    I have a question here!
    I would like to get clarified which is better to use :
    1. Toplink Java Objects from Tables ,
    2.Toplink Entities from Tables
    Could you suggest the best approach, and pros and cons of both the approaches?
    Thanking you ,
    Samba

    Samba,
    Ultimately both are using the same TopLink runtime. In the case of Entities you are using JPA and Java Objects you are using TopLink native API and metadata.
    Going forward I would recommend JPA with TopLink extensions as required.

  • Which is better for gaming Java or C++?

    a friend of mine told me that C++ is better for gaming, but i'm not sure. the thing about C++ is that i've been studing it for the past 3 years and still don't have a strong grasp of it, but java is much more direct and i'd much rather develop my games in java.

    I have finished to programme a game (Space Commanders) using pure java
    http://www.geocities.com/ddmusc/SpaceCommanders. Now I am re-programming the game using Visual C++ . Once I finish I shall put the windows version on the same site. It will be an interseting example of differences in performance between java and C++.
    For programming I think java is easier since it takes automatic control of memory. Problems such as wild pointers , memory leaks and this kind of stuff are not an issue in Java. Unfortunately this is in itself also a disadvatage since you don't have much control on the amount of memory java is allocating (and at what time it deallocates it).
    Java is also a bit slower because of its automaticity and high level structure. What makes me a bit angry about java is that programmes are normally CPU intensive. It is difficulty to run java programmes on old computers such as 486 or Pentium 1. This reduces the portability of the programme which though it can run on many different OSs it can't run on many different computers.

  • Which is better:C++ or Java???

    Hey,People (like my friends)keep tellin me that C++ is better, quicker, etc. than Java! I thnk Java is a lot better. What do you think is better and why so I could have a come-back when me and my friends are arguing about it?

    Neither language is wholly "better" than the other. The more appropriate language is determined by the situation. For example, if you don't have much time to code and need your application to be incredibly portable with minimal extra code and testing, Java is almost certainly your best go. If, on the other hand, you want to write a specialized boot loader for your computer, C or C++ are better choices (primarily because Java can't do that).
    Of course, if you know how to do things a certain way, the way you know how to do them is always better, even if it's less efficient...

  • Java Location API,  Siemens SK65,  Irish network operators

    Hi,
    I'm a senior java developer, just starting to experiment with J2ME.
    I wrote a real simple Midlet to request my location from the Java Location API.
    It runs in the emulator (Eclipse, WTK 2.3) but hangs on my Siemens SK65 phone, which supports JSR 179 ( the java location api ).
    Anyone got any experience of the Java Location API.
    I've a couple of suspects...
    a) that the Irish phone network ( O2 ) doesn't support location based
    services. I previously tried listening for nearby cell broadcasts, but O2
    don't seem to send them out.
    b) that the phone needs GPRS and/or bluetooth settings enabled (tried both)
    This isn't urgent, simply experimenting, but if anyone has any information to point me in the right direction, it'd be appreciated.
    regards,
    Owen

    Cheers deepspace,
    I'll do some research into "AGPS".
    Failing that, I've seen an application "PlaceLabs" which looks interesting, and seems to triangulate your position based on Cell ids.
    duke dollars on their way :-)

  • Java 8: Pb with new java.time api

    Hello,
    I'm trying to use the new java.time api that comes with Java 8 (I already know joda-time).
    I'm using the latest build B124.
    I've a String "01/08/2012_00:00:01", I know that the time ref. is UTC, and I want to convert it to an 'Instant';
    I tried:
    DateTimeFormatter FORMAT_DT = DateTimeFormatter.ofPattern("dd/MM/yyyy_HH:mm:ss").withZone(ZoneOffset.UTC);
    Instant instant = Instant.from(FORMAT_DT.parse("01/08/2012_00:00:01"));
    But it fails with following error:
    java.time.DateTimeException: Unable to obtain Instant from TemporalAccessor: {},ISO resolved to 2012-08-01T00:00:01 of type java.time.format.Parsed
         at java.time.Instant.from(Unknown Source)
    I don't understand what's wrong with my code, and I can't figure out how I should proceed to convert the String to an Instant ...
    Any suggestion welcome,
    Best regards,
    Bernard.

    Originally you stated this:
    I don't understand what's wrong with my code,
    So naturally we focused on how to "understand what's wrong' with your code.
    You will never learn to troubleshoot problems if you just throw your hands up in the air and ask for help just because a complex series of steps doesn't complete successfully. 
    Break the process into its individual steps and check the results of each step to identify which step is FIRST producing an error.
    When a complex or multi-step process has an error you start checking the individual steps of the process to see how far it gets successfully.
    I would expect that converting a String to an Instant should be a basic/simple need, so it should be possible to do it in two lines of code; for the time being, the only way I found is to use a LocalDateTime intermediate variable, which seems quite verbose, and I'm wondering if someone knows a better way to do it, and would be willing to share it here.
    Just a technical distinction: your latest example using a LocalDateTime intermediate variable CAN be done in one line of code by just using dot-notation to avoid creating an explicit intermediate variable. But that variable will still be created implicitly behind the scenes.
    Converting a String to an Instant might be considered a basic/simple need but the set of functionality related to dealing with times, dates, calendars, etc is extremely complex. It makes much more sense to develop the requisite functionality in modules.
    Especially when introducing new functionality such as the 'Instant' class are related package elements introduced in 1.8. That functionality builds on what came before and parsers already existing that know how to deal with all of the possible String variants and formatting options and so on.
    Since that work CAN BE done on-the-fly using dot notation and anonymous implicit intermediate classes there isn't much need to reinvent that functionality in the new classes. If certain uses become standard new methods can always be added (e.g. to the Instant class) that will 'appear' to do things in one step.
    And, being an early adopter release, you can always file a 'bug' or enhancement request from the 1.8 download page. That page has links for 'Report Bugs' and 'Feedback forum' that you can use.
    In this current forum no one can give you an 'official' answer as to why something was implemented a particular way and/or whether that implementation is a 'bug' or was designed to work that way. Only Oracle can do that.

Your class should implement the entire interface and wrap the original Pageable. (for that number n your class can consult the wrapped interface; read the API for the Pageable interface).

  • Error while sending mail when using Java Mail API

    Hi Experts,
    I am trying to execute a webdynpro application which uses the Java Mail API to send emails. The exception that I get on executing the application is :
    Sending failed;  nested exception is: javax.mail.SendFailedException: Invalid Addresses;  nested exception is: javax.mail.SendFailedException: 550 5.7.1 Unable to relay for [email protected]
    Can anybody please help me sort out the issue.
    Regards
    Abdullah

    Hi,
    Usually one get this error if the SMTP server is configured not to relay mails (a security measure) or the SMTP server need the mail to be sent from a trusted IP or with proper authentication. Some SMTP servers are configured to block junk mails.
    Pls check with your  mail server administrator.

  • Which is better to use: BEx query or Web Application as an iView in portal?

    Hi gurus!
    Are there any experienced opinions, which is better - publish a BEx query in portal or publish a BEx Web Application in portal? Is it easier to alter the layout attributes etc. if I create a BEx Web Application first before publishing?
    What is the way of fixing for example filter item height if I publish BEx query in portal - is there a Web Application that it uses anyhow which I can fix? Or can I use in that case iView -properties in portal?
    Thankful for advice
    Sari

    ok, means i can use jsp:useBean tag for all my
    classes that are not actually bean. so it will be
    instantiated at run time and provide efficiency .No. Jsp:useBean is used for java bean components.
    >
    but when should i use import statement in my jsp and
    it happen at translation time so will it create any
    type of burden for my code if i import multiple
    classes.For non-java beans, you need to import the classes, period.
    It's not a burden, it's a necessity.

  • Java Persistence API and creation of databases

    Hi All
    I have designed a small address book application which uses a database to store the information. I have used the new Java Persistence API to take care of my transactions and querrys with the database. This works great for one set database which is generated the first time the application runs and is used all the time.
    However I would like to make it so that the user can create a new address book (database) with a different name, I am not sure how I would do this using the Java Persistence API. I know the persistence.xml file must be placed in the META-INF directory of the source, so how would I be able manipulate the file or could I place the file somewhere else.
    David

    I am using the Derby database. I can create a database by passing the create command when I create the entity Manager like so:
    Connection c = DriverManager.getConnection("jdbc:derby:AddressBook;create=true", "app", "app");My problem is that as I understand it the persistence.xml file must know the name of the database. Unless there is another way of setting this. The line in the persistence file I am referring to is:
    <property name="toplink.jdbc.url" value="jdbc:derby:AddressBook"/>I wonder if I can progamatically set this value so that I have a default database in the persistence.xml and others can then create there own.

    For some reason that link I gave you isn't working right now, but it was today, weird. I would get Tomcat simple because sun uses it in its examples and recommends it. Here's sun's link then, it's probably more useful anyway. http://java.sun.com/products/jsp/

  • Which is better sockets/socketchannel why

    which is better java.io.Socket / java.nio.channel.SocketChannel

    Better for what? They both work. Sockets are simple but only support blocking operations. SocketChannels are about ten times as complex to use but they support non-blocking and multiplexed I/O and also various types of direct and mapped buffering so they can also imply less data movement.
