In JBuilder evrithing works fine. But when I want to run the applet in browser (firefox or IE) I get the message in the java console: accesscontrolException: access denied(java.util.PropertyPermission user.dir read) I asked unkle google for advice and if I correct understand I need the signed jar for using JFileChooser that reads files from client. So I click on JBuilder (2005) File -> new -> archive -> applet jar and the fill all text field, and came to the chackbox: Digitaly signed this archive. Here it stops. What I must to fill for the: * keystore * kestore password * alias * alias password * store type. Can anybody help me. I appologize for broken english.

Matjaz Cof This is an advanced topic for applets, mostly because it is a multi-step, manual process. There are many articles published on the subject. The JDK docs provide this: http://java.sun.com/j2se/1.4.2/docs/guide/plugin/developer_guide/rsa_signing.html The Java Glossary provides links to many resources on this topic: http://mindprod.com/jgloss/signedapplets.html Hopefully you will find what you need in there somewhere. -- Regards, Lori Olson [TeamB] ------------ Save yourself, and everyone else, some time and search the newsgroups and the FAQ-O-Matic before posting your next question.

When you choose File -> new -> archive -> applet jar is the final step something about Digitally signed. Anything about that. Thank's for your reply.

AFAIK, you can't make a keystore from JBuilder. JBuilder helps you with the last couple of steps of the process, but there is a lot of setup involved to get to that stage. -- Regards, Lori Olson [TeamB] ------------ Save yourself, and everyone else, some time and search the newsgroups and the FAQ-O-Matic before posting your next question.

Basically, all certificates expire, and the "free" type of certificates expire a lot sooner. It costs a LOT of money to by a certificate that will be valid for a couple of years. So, basically, don't worry about it. -- Regards, Lori Olson [TeamB] ------------ Save yourself, and everyone else, some time and search the newsgroups and the FAQ-O-Matic before posting your next question.
