Question: I have made an applet in vJ++ which I have to sign. Is there any tool to do it (both signing and cabbing)..?
Answer 1 was published yesterday.
Answer 2: Yes. Dubuild, which you can download from the Microsoft site as part of their Java SDK, can create signed CABs. There's good information on the whole process at:
By default, and for security reasons, Java
applets are contained within a "sandbox." This means that the applets can't do
anything which might be construed as threatening to the user's machine (e.g.
reading, writing or deleting local files; putting up arbitrary message windows;
communicating with arbitrary other machines; or querying various system
parameters). Early browsers had no provisions for Java applets to reach outside
of the sandbox. Recent browsers, however (Internet Explorer 4 on Windows, and
Navigator 4 on all its platforms), have provisions to give "trusted" applets the
ability to work outside the sandbox. For this power to be granted to one of your
applets, the applet's code must be digitally signed with your unforgeable
digital ID, and then the user must state that he trusts applets signed with your
"However, you can also step outside the sandbox and
write regular applications rather than applets, in which case you can access the
other features of your OS. We’ve been writing regular applications all along in
this book, but they’ve been console applications without any graphical
components. Swing can be used to build GUI interfaces for regular applications.
You can generally answer the question of what an applet
is able to do by looking at what it is supposed to do: extend the
functionality of a Web page in a browser. Since, as a Net surfer, you never
really know if a Web page is from a friendly place or not, you want any code
that it runs to be safe. So the biggest restrictions you’ll notice are
