Génération Java birt avec datasource UML/EMF

[nukky]

Bonjour,

je travaille sur plusieurs .rptdesign créer sous IBM Rational Software Modeler avec l'interface Designer, qu'il faut que je puisse générer en java automatiquement.

J'ai repris le tuto ici: http://business-intelligence.develop...eneration_j2ee

Et tout marche à merveille avec les rptdesign dont les datasource sont du XML ou basé sur JDBC, il me génére bien en .doc

Par contre, pour les .rptdesign dont les sources de données sont de l'UML ou EMF, comment les traiter ?
(j'ai ajouter les drivers propres à ibm rsm dans le build path de mon projet Eclipse)

J'ai droit à ce message d'erreur:

un début de piste ? le programme plante lorsqu'il essaye de récuperer les datasources, que biensur l'api Birt ne connait pas.

Salut,

A mon avis le plugin de rational n'est pas indispensable dans le buildpath, même si ça ne mange pas de pain, en revanche es tu certain qu'il est présent dans le classpath au moment de l'exécution? En effet ton projet Eclipse n'est peut être pas configuré pour l'embarquer dans le jar.

Si le code java s'exécute dans une portlet/servlet copie ce plugin dans WEB-INF/lib, si c'est une application java standalone il faut vérifier que le répertoire dans lequel ce plugin se trouve est dans la variable classpath, ou le copier dans un répertoire référencé par ce classpath.

Si le classpath semble ok et que l'erreur persiste je serais curieux de savoir si les rptdesign en question fonctionnent dans un birt designer RCP standard, en copiant le plugin dans le répertoire "plugins" de ce designer.
