Je suis en train d'écrire un rapport Excel en utilisant une action, un contrôleur, une structure de servlets. Le rapport est très encombré et a déjà environ 10 requêtes distinctes. Je dois ajouter environ 10 autres requêtes en raison d'un changement dans le rapport. Y at-il un moyen de le faire sans avoir à continuer à imbriquer les ensembles de résultats? Voici le code existant.Java Struts Report
