[Jean Meurtrier]

Bonjour à tous,

Nous avons un petit problème en ce qui concerne la communication entre serveurs Glassfish 3.1.1 (build 12).

Le code qui suit fonctionne (heureusement):

Code :

Sélectionner tout - Visualiser dans une fenêtre à part

1
2
InitialContext ic = new InitialContext();
remoteBean = (RemoteInterface)ic.lookup("com.mycompany.remoteinterfaces.RemoteInterface");

Maintenant je souhaite utiliser le protocole rmi-iiop en localhost (win 32 - JRE 7):

Code :

Sélectionner tout - Visualiser dans une fenêtre à part

remoteBean = (RemoteInterface)ic.lookup("corbaname:iiop:127.0.0.1:3700#com.mycompany.remoteinterfaces.RemoteInterface");

Je récupère alors l'exception suivante:

Si je tente d'atteindre à distance la même application déployée sur un autre conteneur Glassfish (Linux - JRE 6):

Code :

Sélectionner tout - Visualiser dans une fenêtre à part

remoteBean = (RemoteInterface)ic.lookup("corbaname:iiop:172.21.170.21:3700#com.mycompany.remoteinterfaces.RemoteInterface");

Je ramasse cette autre exception:

J'ai peut-être loupé un truc, ou un stupide paramètre n'est pas correctement configuré dans Glassfish...

Merci pour votre aide! on commence à tourner en rond.

Salut,
c'est quoi ton client ?

[Jean Meurtrier]

J'ai résolu mon problème en deux temps.

J'ai d'abord entré les adresses que je veux contacter dans le fichier etc/Host, en mettant un alias pour chaque adresse. Ensuite, j'ai appelé mes EJB's en utilisant ces noms de substitutions. Dans la doc Oracle, ils suggèrent cette procédure pour des questions de performances, mais si je ne le fais pas, soit mon client plante, soit il se connecte sur mon localhost.

A ce moment, j'ai pu joindre le server, mais j'ai eu des problèmes internes à Corba ("end of stream"). J'ai finalement décidé de détruire et recréer mon domaine et maintenant ça fonctionne.

Par contre, j'ai un autre problème: Comment joindre un serveur derrière un NAT? L'adresse de callback est explicitement renvoyée dans un packet GIOP.

Sinon mon client est une simple page JSF avec un ManagedBean qui appelle un SessionBean dans lequel se trouve le code de mon premier post.

[Jean Meurtrier]

En fait, je souhaiterais savoir s'il est possible pour une machine ayant une adresse privée, de faire un appel et de recevoir une valeur de retour.
L'appelant passe son adresse dans un packet GIOP sous le label "location-forward". Ensuite le server rappelle le client sur cette adresse. Or dans le cas qui m'intéresse, le client renvoie son adresse privée, non connue du serveur. J'aimerais supprimer ou ignorer ce "location-forward".

[hedes]

Bonjour
c'est faisable, je l'ai fait il y a bien des années. De mémoire, il faut aller changer des paramètres de config de CORBA et lui indiquer une autre socket factory.
Il y avait peu de documentation et j'étais allé regarder le code source pour trouver les paramètres. Ca m'avait pris du temps... ;-)

[Jean Meurtrier]

Effectivement, très peu de doc.
J'ai trouvé ceci, ça devrait forcer le "location-forward", mais encore faut-il que le client ait une adresse publique fixe, ce qui n'est pas mon cas.

Connecting to a Remote EJB Module Through a Firewall

To deploy and run an application client that connects to an EJB module on a GlassFish Server instance that is behind a firewall, you must set ORB Virtual Address Agent Implementation (ORBVAA) options. Use the asadmin create-jvm-options command as follows:
asadmin create-jvm-options -Dcom.sun.corba.ee.ORBVAAHost=public-IP-adress
asadmin create-jvm-options -Dcom.sun.corba.ee.ORBVAAPort=public-port
asadmin create-jvm-options
-Dcom.sun.corba.ee.ORBUserConfigurators.com.sun.corba.ee.impl.plugin.hwlb.VirtualAddressAgentImpl=x

Set the ORBVAAHost and ORBVAAPort options to the host and port of the public address. The ORBUserConfigurators option tells the ORB to create an instance of the VirtualAddressAgentImpl class and invoke the configure method on the resulting object, which must implement the com.sun.corba.ee.spi.orb.ORBConfigurator interface. The ORBUserConfigurators value doesn't matter. Together, these options create an ORB that in turn creates Object references (the underlying implementation of remote EJB references) containing the public address, while the ORB listens on the private address specified for the IIOP port in the GlassFish Server configuration.
