exception sur appel de service Web

Question

J'ai WS (jax-ws) déployé sur tomcat.

après un certain temps que je reçois cette exception tout en essayant d'exécuter l'appel WS

ce qui pourrait être le problème qui cause ce problème? comme im nouveau cadre pour JAX-WS ws l'application fonctionne avec MySQL DB, mais je ne pense pas que son rapport avec le problème

s'il vous plaît conseiller

Answer 1

Vous devez google pour « java.net. SocketException: Connection reset »

le Javadoc SocketException indique qu'il est

indique la présence il y a une erreur dans le protocole sous-jacent, tel qu'un TCP erreur

Si les temps de connexion sur le côté serveur, le client obtiendra une réinitialisation de connexion (serveur a fermé la connexion), si le temps client d'abord l'exception sera ConnectionTimeoutException. Comme il s'agit d'un problème transitoire, la solution consiste à capturer et enregistrer toutes ces exceptions et à réessayer.
