Ces derniers jours, on m’a pose plusieurs fois la meme question: “je voudrais un PC portable robuste, puissant et peu encombrant ; que me conseilles-tu?”. J’ai intuitivement repondu a la chaque fois la meme chose: pas de laptop!

En effet, les exigences comme la robustesse et le faible encombrement sont difficilement conciliables, a moins d’en mettre le prix et opter pour une machine de haut de gamme.
Toujours est-il que les PC portables sont toujours tres prises, justement pour leur faible encombrement. L’autre avantage des laptops est leur mobilite. Au titre des inconvenients des laptops, on peut citer la faible evolutivite, la fragilite, la faible duree de vie limitee (18 a 24 mois en moyenne), etc.

Inversement, un PC de bureau est en general plus robuste et evolutif, mais il est hors de question de jouer au globe-trotter avec sa tour, son ecran 19″, son clavier et les innombrables fils.

Cependant, ces derniers mois, les choses ont pas mal evolue. Pourquoi? Les PC fixes ont subi une petite cure d’amaigrissement, certes modeste. Mais, surtout, le phenomene netbook a fait irruption dans les foyers. Au titre de la mobilite, les netbooks battent a plate couture les laptops. Pour le moment, nous n’avons pas assez de recul pour juger de l’esperance de vie d’un netbook, mais il est probable qu’elle soit similaire a celle d’un laptop.

J’en viens donc a la reponse que j’ai donnee a la question ci-dessus: je recommande d’une part l’achat d’un solide PC de bureau, robuste, puissant et avec un disque dur assez gros, d’une part ; et l’achat d’un netbook d’autre part.

Un bon PC de bureau, bien que technologiquement obsolete au bout de 2 ans, peut tenir 4 ans sans problemes s’il est bien entretenu et s’il n’est pas destine a des applications tres gourmandes comme les jeux en 3D. Un netbook apportera lui la souplesse  et la mobilite.

Evidemment, ca coute plus cher d’acheter deux machines au lieu d’une seule. Mais un petit calcul arbitraire montre que ce n’est pas forcement un mauvais plan, financierement parlant j’entends.

On trouve de bonnes machines fixes a 600€, et des netbooks a partir de 200€. Sur 4 ans, et en supposant que le netbook decede au bout de 2 ans, on aura depense 600 + 2*200 = 1000€.

Par contre, en privilegiant un laptop, il est probable qu’il faudra mettre 500€ tous les deux ans. Resultat: 1000€ au bout de 4 ans.

Mais c’est sans compter sur le confort qu’apporte un vrai clavier et une vraie souris, un disque plus large, etc…

A titre d’option, on peut proposer de prendre un disque dur externe assez large, et de diminuer partiellement la taille du disque du PC principal.

Error

Compiling with Maven 2, you have:
org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'sessionFactory' defined in class path resource [businessApplicationContext.xml]: Invocation of init method failed; nested exception is java.lang.NoClassDefFoundError: Could not initialize class net.sf.cglib.proxy.Enhancer
Caused by: java.lang.NoClassDefFoundError: Could not initialize class net.sf.cglib.proxy.Enhancer

Turning Spring logging level to DEBUG, you find:
DEBUG main org.springframework.beans.factory.xml.DefaultNamespaceHandlerResolver - Ignoring handler [org.springframework.scripting.config.LangNamespaceHandler]: problem with class file or dependent class
java.lang.NoClassDefFoundError: org/codehaus/groovy/control/CompilationFailedException


Fix

Add dependencies to Groovy, BSH and JRuby in your pom.xml:

[xml]
<dependency>
<groupId>groovy</groupId>
<artifactId>groovy</artifactId>
<version>1.0</version>
</dependency>
<dependency>
<groupId>org.beanshell</groupId>
<artifactId>bsh</artifactId>

[/xml]

Try of Explanation

Spring depends on the three jars above. But Maven does not link your project to them.

My smartphone (Acer X960) runs under Windows Mobile 6.1 (yes, I know that Android is far better, but it is not the subject). ActiveSync always runs, and even when I close it, it restarts automatically.  I decided to disable it, in order to save power and RAM.

To perform this:

• Start > Programs > Active Sync > Menu > Add server source
• Leave fake address "@"
• uncheck "try to detect..." > next
• give fake login, password, domain, server name, etc.
• uncheck all boxes (tasks, emails, contacts, etc.) > end
• Menu > Panification > choose "Manually..." for both lists > OK
• Menu > Options > Remove the fake server you have added

Case: you work on two different projects, which use different repositories. How to search, find and download needed jars owing to the project?

Maven2 allows you to define different profiles.
For that, edit your Maven2 config file, available at $HOME/.m2/settings.xml.

Define your first profile:
[xml]
<profile>
<properties>
<maven.user>jlalou</maven.user>
<myProject.version>12.3</myProject.version>
</properties>
<repositories><repository>
<id>FirstProjectID</id>
<name>My First Project</name>
<url>http://blabla.bla.bla</url>
<releases>
<enabled>true</enabled>
<checksumPolicy>warn</checksumPolicy>
</releases>
<snapshots>
<enabled>true</enabled>
<checksumPolicy>fail</checksumPolicy>
</snapshots>
</repository></repositories>
</profile>[/xml]

Define your first profile:
[xml]
<profile>
<properties>
<maven.user>genericUser</maven.user>
<myProject.version>45.6</myProject.version>
</properties>
<repositories><repository>
<id>SecondProjectID</id>
<name>My Personnal Project</name>
<url>http://foo.foo.foo</url>
<releases>
<enabled>true</enabled>
<checksumPolicy>warn</checksumPolicy>
</releases>
<snapshots>
<enabled>true</enabled>
<checksumPolicy>fail</checksumPolicy>
</snapshots>
</repository></repositories>
</profile>[/xml]

At the end of the file, add following tags:
[xml]
<activeProfiles>
<activeProfile>FirstProjectID</activeProfile>
<activeProfile>SecondProjectID</activeProfile>
</activeProfiles>[/xml]

Now, on compiling, use the option -P to hint which project/profile you want to use:
maven clean install -PFirstProjectID

Here is the bug I have reported this morning in OOo (Issue#107031)

Hi,

Here is a “bug” I encountered:

• I copy an image in the clipboard
• I launch OOo 3 on Vista / Intel Core 2 / localized in French
• I paste the image
• Right click > Picture > Picture > check “Vertically” and “Horizontally”
• (then the image in flipped on both directions)
• I save the document in Word 97/XP
• I re-open the document: the image is no more flipped (neither vertically nor horizontally).

I reproduced this case under XP/Core 2/localization in English with OOo 3 portable.
Yet, when I save in ODT format and reopen the file there is no issue, the file is flipped.

Thanks and regards,

Jonathan

This morning I tried to save some space in my computer. I found a file changelog.data in the folder <domain>\admin\data\ldap\ldapfiles of which size was more than 7 Go… This file is used by WebLogic, but I don’t know for which purpose.

I performed a head command on it, here is the output:

I assume this is a kind of binary/XML logger.

You can stop your server, delete this file (and another: changelog.index) and restart the server. The files will be created again.

Pointsec Protector Client is an application that blocks USB ports on a PC. This has an interest, especially for lamers who introduce viruses to great companies networks because of their contamined USB keys. But for developpers it’s very painful (unused resources and… other stuff 😉 ). Pointsec Protector Client is installed as “super admin” process: impossible to kill.
Here is the description of this application on its editor website:

Check Point Media Encryption secures sensitive corporate data and blocks incoming malware by encrypting removable media such as USB storage devices, CDs and DVDs and controlling activity (read, write and execute) on ports and devices. All device content is automatically encrypted in the background for a transparent end-user experience. Unique to Check Point, users can access encrypted media securely on unmanaged computers with no client installation. As the only device and port control solution integrated with a single endpoint security agent, Check Point Media Encryption simplifies compliance and reduces administrative overhead. Now supports Windows 7.

To get through Pointsec Protector Client, here is the way:

• you need be admin in your local computer
• Start > Control Panel > Administrative tools > Services > Select "Pointsec Protector Client" > stop the service
• open Windows Explorer, go to C:\Program Files, rename CheckPoint folder as XXXCheckPoint
• reboot your computer

You should have get rid of Pointsec Protector Client. I think this method should work on most applications started as service by a “super admin”, yet I have not tested.

Case:

You have to use an equivalent to “select for update” in Hibernate, for instance when you migrate en EJB entity to Hibernate.

Fix:

In your query, use the option LockMode.UPGRADE. For instance, you will have:

[java]sessionFactory.getCurrentSession().load(MyMappedClass.class, myPk, LockMode.UPGRADE);[/java]

Context:

Client-server communication over JMS.

Explanation – Fix

The client JVM was in version 1.6, the server was in 1.5.
To fix the issue, the client must be run with Java 1.5.
Possibly, the client may laucnh the JVM with the option -Dsun.lang.ClassLoader.allowArraySyntax=true.

Context

I have to send JMS messages on queues on clustered servers: t3://firstServer:1234 and t3://secondServer:5678.

The destination queues are retrieved in Spring, thanks to a property like:
[xml]&lt;property name=&quot;providerURL&quot; value=&quot;t3://firstServer:1234,t3://secondServer:5678&quot;/&gt;[/xml]

Error:

I receive the following error:

[java]javax.naming.ConfigurationException [Root exception is java.net.MalformedURLException: port expected: t3://firstServer:1234,t3://secondServer:5678][/java]

Explanation and fix:

When you send messages on many queues, you must not repeat the protocol (here: t3://)! Fixing the issue is very simple: you have to remove the second t3:// in Spring property:

[xml]&lt;property name=&quot;providerURL&quot; value=&quot;t3://firstServer:1234,secondServer:5678&quot;/&gt;[/xml]
