Olá junaooaks

Esse tal de JPlogin é algum framework ou .jar a parte? Se sim verifique se ele está setado no classpath

Renato_Ceadareanu 28 de mai. de 2009

Se nao for verifique se encontra essa classe, pois a JVM está reclamando que ela nao existe

Abraços

junaooaks 28 de mai. de 2009

pessoal o que eu faço

Renato_Ceadareanu 29 de mai. de 2009

Nao tenho total certeza… mas se nao me engano para chamar applet voce deve empactar o fonte em um .jar, e depois referencialo na tag de seu html:

Tipo:

<applet code="br.com.minhaClasse.MinhaClasse"   
    archive="/Minha-WEB/applet/MinhaWeb.jar"  width="0" height="0" name="MWEB" ID="MWEB">

Da uma estudada melhor… aqui no guj tem alguns posts sobre isso

Falow!!!

junaooaks 29 de mai. de 2009
