    Subject: For help ----- Signed applet & Java Plug-in

Dear sirs,

I have run the JDK1.1.x-Signed Applet Example (offered by
http://java.sun.com/security/signExample/signedWriteFile.html) with
appletviewer successfully. But when I ran it with Netscape, I got the
security exception -----=93writeFile: caught security exception=94, which=
is

an error message printed by the Signed Applet Example. In the relating
documentation of Java Plug-in, I was told Java Plug-in supports standard

JDK 1.1 signed JARs. So I began to try to work with Java Plug-in in the

browsers to get access to more recent JDK technology and I downloaded
the latest Java Plug-in (plugin-11i-win32.exe).

Steps I followed are as follows:

1. Install Java Plug-in 1.1
2. Use the Java Plug-in tag (EMBED) in place of the APPLET tag in an
HTML page.
3. Use the Java Control Panel to enable the Java Console and copy file
identitydb.obj into the user=92s home directory printed out by the Java
Console.
4. Follow the steps offered by JDK1.1x-signed Applet Example

Unfortunately, I got the same result----- =93WriteFile: caught security
exception=94

BTW:
1. Can I print from a Java Plug-in signed applet with Netscape?
2. Could you offer a best way to print from an applet with Netscape?

I use JDK1.1.4, Netscape4.04 and windows95.

Appreciate for your helps.

Thanks and best regards.
