Signing an applet

[DistantJ]

So I see the FTP object is now supported, can an applet be signed to access files from a user's computer, or is it still only web start apps?

[Czentnar]

You can sign the applet, there's a description in the MMF2's help.

[DistantJ]

So I mean in theory can a web applet access a user's local files and upload them to a server via the FTP object? It's just I heard that this couldn't be done with the previous build.

[Czentnar]

If the FTP object works in the signed internet applet correctly, it can be done, I think.

I have another quetion about signing an applet. The help of TGF2 says about the signing of an applet: "Connect to http://developers.sun.com/downloads/ and choose to download Java SE SDK." But on the page of the link, there is no Java SE SDK (or I can't finde it), only Java SE (JDK). So where is it posible to get Java SE SDK, or is it posible to sign an aplet with Java SE (JDK)?

[Dynasoft]

I think it is a typo, and the "JDK" is what you want.

[pnekdo]

OK, so I installed Java SE (JDK), but I have never used Java before, and when I open the Java folder there are at least 50 exe files. And when I run one of them nothing realy happens. In the help it says "Once installed, open a command line window". So my question is, how do I open a comand line window?

In you program folder, accessories.

Thanx. I managed to sign an applet but there are two notes that I would like to know more about.
The first shows up after I signed the applet and it says "Warning: the signer certificate will expire within six months." So what does that mean - that I will have to sign the applet again after six months, or just, that I will have to create another signature?
The second shows up befor I run the applicatin in a browser and it says "The application's digital signature cannot be varified. Do you want to run the application?" Is there a way of avoiding this message?

I will have to create another signature?

You'll have to create a new certificate and sign your applet with it.

"The application's digital signature cannot be varified. Do you want to run the application?" Is there a way of avoiding this message?

Probably you have used a test certificate. To avoid this message I think you have to purchase a certificate from a company like Thawte or VeriSign.
