PHP fil og build skal nok merges ind i dine. PHP fil indeholder en session_start() og
mayscript attribut på applet tag. Build har tilføjer plugin.jar til javac classpath
(browseren har allerede den, så den skal ikke i manifest eller uploades).

nu er den der vist. jeg kopierede plugin.jar til bin mappen

hvad skal jeg så uploade?

FtpUploadApplet.jar
UploadThread.class
?

PERFEKT! det funger!

22:30:53: det forstår jeg ikke? :)

Ved du forøvrigt hvordan man certificere filen mere end 6 md ad gangen?

og hvad betyder mayscript="1"

mayscript="1"

tillader appletten at bruge JavaScript

22:30:53 siger at den sidste kode dækker spørgsmål 1+2+3

Hvis du bruger:

jar cvfm FtpUploadApplet.jar manifest.txt FtpUploadApplet*.class UploadThread.class

skal du kun uploade FtpUploadApplet.jar

plugin.jar skal kun bruges ved compilation - browseren har den i classpath når appletten kører

Når du kører:

keytool -genkey ...

så prøv og angive:

-validity 3650

tak for hjælpen :)
lig et svar

når du når 1 million point, regner jeg med at der lyder en speciel tak til mig hehe
