Boa tarde, estou fazendo uma aplicação web e quero abrir um documento pdf através do Java. Deve abrir em todos os OS’s.
Utilizei o java.awt.Desktop, porem ele só funciona quando a aplicação esta em local, quando subo no servidor GlassFish ele da HandlessException. Alguém tem alguma ideia de como posso abrir o documento?
