    Subject: A question!

Dear author:

I am a Chinese student. I want to use the signed applet to do some work. After visiting your company's homepage, I follow the
steps to run the your jdk1.2 signed applet example successfully. But when I try to put the same applet on my own server, it do
esn't work.

Server I use is WINNT. Web Server is IIS.

Client is Windows 95.

Browser is Netscape 4.05

My steps as follows:

server:

step 1:

keytool -genkey -alias sym -dname "cn=sym, ou=net manager, o=usst, c=cn"

step 2:

jar cfv signedWriteFile.jar writeFile.class writeFile.html

step 3:

jarsigner -verbose signedWriteFile.jar sym

step 4:

keytool -export -alias sym -file sym.x509 -rfc

client:

step 1:

keytool -import -alias sym -file sym.x509

step 2:

policytool

content of .java.policy :

keystore ".keystore";

grant signedBy "sym", codeBase "http://202.120.223.12/sym/signedWriteFile.jar" {
permission java.io.FilePermission "C:${/}writetest", "write";
};

I put the .java.policy and .keystore on the directory C:\Windows.

I don't know why the signed applet still can't access the client resources. Perhaps something wrong with my
operation, but I can't find it. Do we need do some configuration on Server?

Please give me some advices. Thank you!
Sincerely
Shi Yongmei
