JNLP just Install and Update

[Rafael Morales]

Hi forum,

My question is very simple. Where can I fin real examples about how to Install and/or update my Application.jar. All I find is with <application-desc /> but not with <installer-desc>. Now I only replaced the application with installer but I get this error message:


MissingFieldException[ Falta el siguiente campo requerido del archivo de ejecución: <application-desc>|<applet-desc>]
