Olá a todos,
Estou desenvolvendo uma aplicação utilizando applets e servlets, porém estou com um problema muit estranho.
Utilizo o Tomcat gerenciado pelo eclipse, e quando testo a aplicação, ela roda certinho, porém quando utlizo a aplicação em um servidor rodando tomcat rodando normalmente, sem o eclipse, dá um erro na comunicação entro o applet e o servlet:
