Problème de connexion MySql
Bonjour , je n'arrive pas me connecter a ma BDD , pourtant je n'ai aucune erreur quelque warnings comme :
Classpath entry ***/mysql-connector-java-5.1.12/mysql-connector-java-5.1.12-bin.jar will not be exported or published. Runtime ClassNotFoundExceptions may result.
Classpath entry eclipse.fproj.jdt.libprov.osgi/jpt.jpa is marked for publish/export but is not exported on the project classpath. Classpath visibility within Eclipse and at runtime will differ
No connection specified for project. No database-specific validation will be performed.
Projects must be referenced by an EAR or a WAR to use classpath publish/export dependencies whose runtime path (../) maps into the parent component.
The serializable class NewJFrame does not declare a static final serialVersionUID field of type long
Je pense que c'est lié au warnings mais je suis pas sur , je comprend rien.
voici mon code au cas ou . Merci
