Olá, estou testando o ScadaLTS 1.1 (imagem disponibilizada pelo @jeff_pimenta), mas as public views não estão funcionando.
Estou acessando ela pelo endereço abaixo, a página carrega mas aparece a seguinte mensagem de erro:
A server error has ocured. More information may be available in the console.
http://192.168.15.200:8080/ScadaLTS/public_view.htm?viewId=7
A tela fica assim, onde está cada objeto fica com uma lupa e nada acontece se clicar nelas.
A opção de acesso anônimo está como set (já fiz o teste como read e o comportamente é o mesmo).
Nos arquivos de logs do tomcat é registrados alguns logs quando é realizada a tentativa de abrir a public view.
Alguém pode me ajudar a descobrir onde está o problema?
Obrigado.
Segue abaixo os logs do tomcat.
