ciao a tutti,
ho iniziato quest'estate a studiare jsp e dopo ore di lettura si passa finalmente alla pratica.
arrivo al punto....ho istallato tomcat, jsdk, jvm.
in seguito ho modificato la variabile di ambiente.
la pagina http://localhost:8080/index.asp funziona correttamente, ma appena metto nella stessa cartella la pagina prova.jsp con il seguente codice:
<html>
<head>
<title>sono una pagina jsp</title>
</head>
<body>
<% out.prinln("sono una pagina JSP"); %>
</body>
</html>
mi restituisce il seguente errore:
HTTP Status 500 -
