How to list the available algorithms ?
Hi,
I would like to get all the available algorithms so that the user can choose the one he wants.
Is it possible to write a generic function that can encryt/decrypt a file with an algorithm as parameter
Because I've got the following problem : I use this code to list the available algorithms :
public static String[] getCryptoImpls(String serviceType) {
Set result = new HashSet();
Provider[] providers = Security.getProviders();
for (int i=0; i<providers.length; i++) {
Set keys = providers[ i].keySet();
for (Iterator it=keys.iterator(); it.hasNext(); ) {
String key = (String)it.next();
key = key.split(" ")[0];
if (key.startsWith(serviceType+".")) {
result.add(key.substring(serviceType.length()+1));
} else if (key.startsWith("Alg.Alias."+serviceType+".")) {
result.add(key.substring(serviceType.length()+11));
return (String[])result.toArray(new String[result.size()]);
} I call it as : getCryptoImpls("Cipher");
But some elements of the list are not available !
Other problem :
I encrypt/decrypt files using a password, and when I use different algorithms when encrypting and
decrypting, it works ! Strange ...
I create a key like this :
SecretKey key = SecretKeyFactory.getInstance(algo).generateSecret(keySpec);here is the whole code for you to understand better :

(sorry for the french comments...)From 11.1 onwards, the below two views are available to identify the jar files loaded into the Database.
JAVAJAR$
JAVAJAROBJECTS$
By querying the JAVAJAR$ view you can know information about the JAR files loaded into the Database and using JAVAJAROBJECTS$ view you can find all the java objects associated with the given JAR file.
These views are populated everytime you use LOADJAVA with "-jarsasdbobjects" option to load your custom java classes.
But unfortunately this feature is available only from 11.1 onwards and there is no clear workaround for above in 10.2 or earlier. -

Encrypt passwords in cle-providers.xml
Hi,
I posted this question on JHeadstart forum but they advised me to find help here.
I have a JHeadstart application (say the shipped jhsdemo) use 9iAS R2 OC4J 9.0.3 and consider to use OEM for managing the application.
How can I use encryption to protect the user passwords in cle-providers.xml. I know I must enter encryption value BASE-64, but how can I get the password to be encrypted and how is it decrypted again?
Another question: why do I need to enter username+password once as part of the jdbc thin URL in "connectionstring" and once as separate arguments "user" and "password"? The same question for db host, sid and port.
Thnx,
Rinse Veltman

Reference a dataSource in cle-providers.xml
How can I reference in cle-providers.xml a dataSource specified in data-sources.xml in my OC4J configuration. So that I can specify my datasources in a generic way
outside my application?
My cle-providers.xml :
<?xml version = '1.0'?>
<cle-providers>

<property name="drivertype" value=""/>
<property name="failover" value=""/>
<property name="scope" value="request"/>
<property name="managestate" value="false"/>
</provider>
</cle-providers>
My data-sources.xml:

</data-sources>
I also posted this question on cleveland forum. In the JHeadstart documentation I miss a proper description of what
my options are in cle-providers.xml. In the Jheadstart developer guide there are references to Cleveland docs but
where can I find these; is it possible to ship these together with the JHeadstart documentation?

CIBER Solution PartnersRinse,
Do you want BC4J to use your connection defined in data-sources.xml, instead of its own connection pooling mechanism? Or do you want to use the connection straight in your own code?
For configuring BC4J to use data-sources.xml, I copied this from the Jdev online help:
For Local or web module deployment, you can use a JDBC URL or a JDBC data source. However, make sure that you rebuild the Middle Tier BC4J project to make the configuration available to the JSP client. You'll also need to edit the x:\<ORACLE_HOME>\j2ee\home\config\data-sources.xml file to include a matching <location> value that you are using in your BC4J project. By default, local or web module deployments use the JDBC URL connection.
In combination with the MVC Framework cle-providers.xml, this means you should specify the data-osurces.xml <location> value as the value of the connectionstring attribute within the <provider> element. We have not tested this though...
Note that although using data-sources.xml is more "standards-based", the connection pooling facility of BC4J is superior with its support for high-water marks. See jdev online help for more info on this. I also think that password encryption is not yet possible in data-sources.xml.
I could not find the MVC Framework User Guide on OTN anymore. I will check where it is located and let you know.

Does & in cle-providers.xml connectionstring work ?
I have following connectstring in the cle-providers.xml file:
<?xml version = '1.0' encoding = 'windows-1252'?>
<cle-providers>
<provider name="OpaServiceProvider" class="oracle.clex.persistence.bc4j.ApplicationModuleProvider">
<property name="persistencebase" value="oravision.opa.persistence.bc4j"/>
<property name="modulename" value="oravision.opa.persistence.bc4j.OpaModule"/>
<property name="connectionstring" value="jdbc:mysql://localhost:3306/opa?ultraDevHack=true&user=root&password=test"/>
<property name="user" value=""/>
<property name="password" value=""/>
<property name="host" value=""/>
<property name="sid" value=""/>
<property name="port" value=""/>
<property name="encryptiontype" value=""/>
<property name="drivertype" value=""/>
<property name="failover" value=""/>
<property name="scope" value="request"/>
<property name="managestate" value="false"/>
</provider>
</cle-providers>
Does the & work ?
The connectstring URL should be:
jdbc:mysql://localhost:3306/opa?ultraDevHack=true&user=root&password=test
which works in the BC4J tester!Ahhh. The forum isn't showing it as I meant.
This is my connectionstring property:
<property name="connectionstring" value="jdbc:mysql://localhost:3306/opa?ultraDevHack=true& amp; user=root& amp; password=test"/>
<property name="connectionstring" value="jdbc:mysql://localhost:3306/opa?ultraDevHack=true& a m p ; user=root& a m p ; password=test"/>

Bonjour,
J'utilise un cDAQ-9174 et j'observe des perte de communication càd que j'ai des erreurs NI qui apparaîssent comme-ci je déconnectais le module du port usb.
Sous Windows, dans la barre des taches, j'observe la perte de com et la nouvelle détection du module juste après ???
Avez-vous déjà rencontré ce problème ? C'est + un problème Windows ou NI ?
Merci d'avance.
Philippe B.
Certified Associate Developer / Dépt Moyens d'essais
www.ingenia-system.comBonjour,
Il se peut que Windows passe le port USB en veille (mode sleep ou hibernate) et cela peut parfois causer ce type de comportement.
Vous pouvez essayer de désactiver la mise en veille des ports :
Clique droit sur le Poste de travail » Propriétés » Matériel » Gestionnaire de périphérique » Concentrateur USB Racine » Gestion de l'alimentation.
Ce n'est qu'une hypothèse. Pouvez vous fournir le code d'erreur associé ?
Est-ce le cable USB original ?
Disposez vous d'un sniffer USB ? (matériel ou logiciel).
Cordialement,

Does any actually use Pert view?
The Pert view seems to very hard to organize activities especially when you're working with a couple hundred of them. Does anyone actually use the Pert view, and why do you use it instead of the bar chart? Is Pert better for small projects that don't have many activities?
Mike M ,
Under most circumstances we do not use a "pert" formatted chart. They are cumbersome with larger projects but every once in a while a stakeholder has a preference for that particular "look". It all depends on the way the project manager or lead is used to working with his or her schedules.
I find them useful in the planning stages of putting a schedule together.
hope this helps, -
Hello sap experts,
Can you please tell me the availability of PERT functionality in SAP PS ? I know CPM is available in sap.
PrasadYes, Pert Model is supported in SAP PS:
You have features like Milestone monitoring, critical path analysis,Cost analysis, alerts, network representation and gant representation, relations between activities etc.
Can you eloborate on what kind of functionalities are expecting ?

Bonjour, je suis en voyage en irlande et j'ai quelques soucis pour me connecter au wifi, tant avec mon iPhone qu'avec mon MacBook Pro. Après avoir introduit la cle wpe, il ne se passe plus rien.

MerciMerci jmlevy de te pencher sur mon problème.
Voilà une photo de mon panneau page :
Puis une autre d'une page qui ne ressemble plus à rien après changement de pagination:
Voici une ancienne page 28 devenue page 29. Fantastique, non ?
On peut voir :
Que mes blocs sont décalés par rapport à la maquette
que le bloc noir de la page 28 déborde sur la page 29.
Que mon bloc de texte est perturbé par l'ajout sous-jacent d'une page de maquette
que ma pagination a conservé les attributs d'une page pair (numérotation à gauche) alors qu'elle est passée impaire.
J'aurai considéré comme normal que mon ancienne p.28 se soit déplacée en page impaire avec le bloc texte bien placé ET avec les attributs de page (liés au gabarit, tels que pagination, filets, bas de page roulants) modifiés automatiquement. Or il n'en est rien.
Tu me demandais des éclaircissements par rapport à "J'importe mes gabarits dans le document au fur et à mesure de la construction du livre et je libère les éléments de gabarit afin de pouvoir couler le texte et disposer l'icono. Lorsque c'est fait, je ne retourne pas dans le mode page d'InDesign. J'attaque la page suivante." Voici, plus en détails ce que je fais au moment où je monte une nouvelle page. Mes gabarits ont été préparé en amont.
J'ajoute une page au document (ex : une page de texte)
je lui confère le gabarit qui va avec (ex : C-présentation ch1, cf plus haut)
je libère les éléments de gabarits pour pouvoir couler le texte et disposer les images.
quand ma page est finie je recommence l'étape 1.
Est-ce que c'est à l'étape 3 que je me plante ?
Est-ce qu'il y aurait d'autres explications à ce malheureux schmilblick ?
Merci d'avance. -

Bonjour,
D'abord, ce forum est essentiellement en anglais, donc ce serait le bon moment pour se replonger dans la langue de Shakespeare...
Ensuite, pour résoudre ton problème, il te faut le CD ou DVD d'installation de ton OS (la version de MacOS X actuellement installée sur ton Mac). Après ça, il te faut :
1) Démarrer sur le CD/DVD en appuyant sur la touche "alt" au démarrage, puis en choisissant le CD sur l'écran ;
2) Sur l'écran d'installation, au menu "Installeur", tu as un choix qui s'intitule "Reset password" ou "Changer le mot de passe utilisateur" si tu es en français ; alternativement, tu peux cliquer sur Outils/Utilitaires, sélectionner le volume de démarrage, puis le compte pour lequel tu dois remettre un nouveau mot de passe. Entre un nouveau mot de passe dans les cases prévues à cet effet, confirme le nouveau mot de passe, et voilà...
Redémarre ton Mac normalement, sans le DVD, et tu devrais être tiré d'affaire. -
