Hibernate, AuditLogging, cannot configure listeners in persistence.xml

First, what's my goal

I want to do an audit log. I read the http://www.hibernate.org/318.html and there two different approaches were mentioned.

The first is using a Listener.

The second is using the new eventing model in Hibernate3.

The author said that he couldn't make the eventing approach work for an unknown reason.

I'm using Hibernate via JPA. I'm using it in an EJB. So the problem
with the first approach is that it is difficult (if possilbe) to supply
the same transaction to the interceptor so that it can write an entry
in the audit log. There is a solution with a static field holding a
session or an EM, but that seems ugly.

So I chose the second approach. I created a class, inherited few
eventhandlers (PreInsertEventListener, PostUpdateEventListener ) and
tried to add the class as a listener.

Using the API, it worked (the callback methods in the listeners were called):

AnnotationConfiguration configuration = new AnnotationConfiguration();


configuration.setListener( "post-update", new Test1() );

configuration.addProperties( hibernateProperties );

EntityManagerFactory factory = new EntityManagerFactoryImpl( configuration.buildSessionFactory(),

  
PersistenceUnitTransactionType.RESOURCE_LOCAL, true );

EntityManager result = factory.createEntityManager();

Using properties (as if using persistence.xml) failed(the callback methods in the listeners were NOT called):

Properties hibernateProperties = new Properties();

...

hibernateProperties.put( "hibernate.ejb.event.pre-update", "package.Test1" );

hibernateProperties.put( "hibernate.ejb.event.pre-insert", "package.Test1" );

 
AnnotationConfiguration configuration = new AnnotationConfiguration();

configuration.addProperties( hibernateProperties );

EntityManagerFactory factory = new EntityManagerFactoryImpl( configuration.buildSessionFactory(),

  
PersistenceUnitTransactionType.RESOURCE_LOCAL, true );

EntityManager result = factory.createEntityManager();

Ideas why?

'Sucks' category

There's a trend - there are a lot of articles here in which I bitch about something. So there should be a category called 'Sucks'.

Update: reviewing the articles I found a lot of candidates for the category, it comes out that all I'm doing is bitching about stuff - I should change the subtitle of the blog πŸ™‚

@Override in eclipse

When one implements an interface, the template in Eclipse puts an @Override and it does not complain about it. Ant javac task also compiles without warnings.

Sometimes other Eclipse instances start to complain exactly for that @Override stating that there's no method that's overridden. Well, Eclipse, please do make up your mind.

http://java.sun.com/j2se/1.5.0/docs/api/java/lang/Override.html
"Indicates that a method declaration is intended to override a
method declaration in a superclass. If a method is annotated with
this annotation type but does not override a superclass method,
compilers are required to generate an error message."

Well, that's not very clear. As far as I remember an Interface is a pure abstract class, right? So, which one's correct.

P.S. Sometime ago I was having a similar problem with Eclipse and generics - Eclipse only gave a warning about something (can't remember what exactly), but the javac said that it was an error - Google said something like "eclipse uses jikes, you use javac". So what, aren't there specs?!

Update: apparently JDK5 (or 1.5, suit yourself) does not allow that. So in order to get all the wrong @Overrides - set the Compliance level to 5.0 (Eclipse -> Window -> Preferences -> Java -> Compiler -> Compiler compliance level ) - and..... correct them. I have 29 left.

Referrers from live.com

All the referrers to this blog from live.com come like that:
http://search.live.com/results.aspx?q=class&form=QBHP or
http://search.live.com/results.aspx?q=interface&form=QBHP

The search word seems to be only 'class'. I can't believe that I come out in a search for only the word 'class'. I guess all the other words from the search are stripped which, if on purpose, is stupid, and, if not, ignorant.

In a few days

In a few days this adventure (having a blog) is going to have its first birthday. I remember the birthday because it is embedded in the admin password (yea, try me ;).

Today I was reading a few articles about having a blog (here and here) and the impression I got left with was that starting a blog is not always a good idea and to do that you have to have something to share and to follow some rules and most importantly have a goal.

F**k that. (Update: I don't know why I put asterisks, maybe I'm afraid of the moderators ?!)

I don't know if I have something to share. I don't know if I have a goal set for my blog. I didn't know about the rules until today. But I don't care.

What made me start the blog was an article from Joel (I can't find it right now) that simply said that a blog can help you express yourself better, can help you perfect the language you present your blog in, can help you understand yourself better. And one other thing - get more feedback for yourself - and that one is particularly precious for me.

So, do I follow the rules - no. Do I care - I guess not. (yea, sometimes I check the logs to see how 'famous' am I and the good results and some comments boost my ego, but that's pretty much it). Overall, I find it a good experience and the time spent on the blog wasn't completely waisted.

What am I going to do from now on - I guess pretty much the same thing.

P.S. Thank you my one reader for the continuing support and the few comments you left from different IPs (appreciate the effort). I would gladly buy you a beer.

E-banking - finally, there may be a winner

Seeing these posts first may help get the context of the talk:
What not to do when you're a bank
What to do when most e-banking interfaces suck?
First Investment Bank, the sequel
SG Expressbank

Being stuck with SG Expressbank made electronic transfers impossible, because they didn't work with epay.bg (prohibited) nor did they work with the e-banking software (every recepient has to be registered offline on-site (bank office), and for the ones that are registered the software does not work πŸ™‚ ).

Almost by accident I tested a card I had in epay.bg for the balance (most banks have stopped this service, because of too many requests). And... I got it. It was working. Strange.

I remebered that I had registered the e-banking for that bank and had left the user/pass somewhere.

After a few days of searching I found it.  Keep in mind that getting the user/pass from the bank was quite an adventure and took more than 20 days and quite a few trips to the local office.

The login screen is right on the main page of the bank. I was amazed to see how easy the generation of the certificate was. While doing it I saw that they support smart cars (e-signatures). Well done.

The interface is really user friendly. Supports almost everything or at least it seems so. I haven't tried it yet, because the bankaccount is nearly emtpy.

From the interface notifications can be defined: SMS notifications, email notifications. Now I'm waiting to see whether it works.

A minor drawback was that I can't tranfer money to another bank account via epay.bg - I guess only FIB cards can (FIB is connected to epay).

And because I'm lazy to do it the old-fashion way - now I'm using the only possible way to transfer money electronically from SG Expressbank card to the new card I have - the epay's microbill (микросмСтка) - another thing I have to learn how to use. It was quite straight forward to start up and use, but it takes a few days (in my case 2 full days) to tranfer the money and the commissions are not going to be small.

ant junitreport task cannot set vm arguments

ant junitreport task creates a html report from junit xml report files.
If the xml files are numerous enough and/or large enough (mine were 102MB total ), the task crashes with OutOfMemoryError.

Solution? set the GLOBAL variable ANT_OPTS. This changes defautl ant conf for the whole machine this setting is on.

CVS: dying gasps from server

Why can't there be software that just works?!

There's a CVS server (version 1.11.22) [one can get the version with cvs version -d cvs_root] on a Linux machine.

There's a Hudson on the Linux machine that queries the cvs just fine.

I have Hudson on a Windows machine that gives me:

cvs checkout: dying gasps from server unexpected

The explanation? Here's the best I could find:
dying gasps from server unexpected

There is a known bug in the server for CVS 1.9.18 and older which
can cause this. For me, this was reproducible if I used the -t global
option. It was fixed by Andy Piper's 14 Nov 1997 change to
src/filesubr.c, if anyone is curious. If you see the message, you
probably can just retry the operation which failed.

Sources:

http://cvsman.com/cvs-1.12.12/cvs_210.php
http://developer.apple.com/opensource/cvs/cederquist/cvs_174.html

Now check the version of the server I have (in the beginning). So what do we do now?!

Why can't there be software that just works?!

Eclipse, interface implemented by classes, but the implementation is in a base class

Suppose there's an interface

interface PrimaryObject {
    int getVersion();
}

and

public class Base /* not inheriting PrimaryObject */ {
    int getVersion(){}
}

now suppose there are a lot of classes like

public class Class1 extends Base implements PrimaryObject {
}

So why did I mention Eclipse in the title:
When you go to the interface and press Ctrl + T on the interface itself you get a list of all the classes like Class1:

But you you press Ctrl + T on the method you get NOTHING:

Eclipse fails to show all the classes that implement this interface and this method.

@Lob in JPA, what if the class is not Serializable

If you have

@Entity
public class Student {
    @Lob
    private static MyPictureClass picture;

and suppose you forgot to put Serializable to MyPictureClass, then guess what: there's no exception. You have to check the data in the DB.

Surprise no2:
Suppose MyPictureClassis a base abstract class and it is not Serializable. Suppose every inheriting class is Serializable. Then what happens? Well one thing's for sure: there wouldn't be an exception, but there wouldn't be any data in the DB (you'll get null). The runtime checks (in Hibernate) check the signature of the defining class I suppose, not the supplied class at runtime - and I would assume the opposite, because serialization works the opposite way. Maybe it's because Hibernate does some runtime bytecode modifications.

Primitive types as fields in an JPA Entity

The JPA spec supports primitive types as @Columns. What they don't say (assuming Hibernate is the implementation (maybe TopLink does that too)) is that this column becomes nullable = false and the default value is the default for the primitive type. And that is so, even though the @Column(nullable by default is true.

So

@Entity
public class Person {
    private int age;
    private boolean male;

actually means

@Entity
public class Person {
    @Column( nullable = false )
    private int age = 0;
    @Column( nullable = false )
    private boolean male = false;


So watch out.

SG Expressbank

Another bank that I'm unhappy with - SG Expressbank. Reasons

  1. They charge me with 0.69 on ATM withdrawal.
  2. They charge me with 1.39 (monthly fee)
  3. Interest rate: 0.00
  4. E banking application - outrageously bad (screws up every file format I request, cannot send money to an account without going to the bank (some security shit), ugly, not intuitive)
  5. The service is far from good.

I'm looking for a decent bank. Any ideas?

hudson ant javac unit-tests fork=true, cannot start javac.exe compiler

Hudson is a continuous integration tool similar to CruiseControl. It has a very good web GUI for defining tasks unlike CruiseControl.
Inside it I have configured a call to an ant task.

Strangely enough in on of the projects that had to be build I got:

build.xml:200: Error running _path_to_jdk_/javac.exe compiler

Strange.

I double checked the script in eclipse. It worked.
Manual call to ant on the eclipse machine also worked.

Then I went to the Hudson machine (a test environment). I ran the script manually. The same freaking error.
I copied the whole dir to another place on the test environment: no problem.

Maybe it's the credentials: added read/write to all. Still the same error.

Then I ran the script with: ant -verbose and see what I got:

_path_\build.xml:75: _path_\javac.exe compiler

Cannot create a process?!
That's weird.

So tired enough I did something desperate:

From

<javac fork="true"

I went to


<javac fork="false"

and it worked ..... πŸ™

Keep in mind that in the same build project I was calling a few other build.xml doing <javac fork="true"
several times before this one.
But this one was the only one having a reference to junit.jar (somewhere on the net I saw an article saying something about junit but don't remember what).

So I left it like this.
