Hi, Frank.
Thanks for your interest.
The problem is , the browsers dont compare the certificates of webutil.jar and jacob.jar with its certificate list.
In Linux the browser, Mozilla 1.7.8, look for the certificates in
/usr/lib/jvm/java-1.4.2-ibm-1.4.2.0/jre/lib/security/cacerts
In this file 'cacerts' are storing all the certificates, also exist another certs file in the home user directory the tree began in .java, but it is only a copy of the cacerts file locate in /usr/lib/jvm/java-1.4.2-ibm-1.4.2.0/jre/lib/security
Duncan Mills resolve this question in this forun post
Certificate in Linux
But I have store the keystore file, named keystore, in this subdirectory , and dont work.
Also I have copy the keystore file with the name cacerts in that subdirectory but then the java console say that it is in wrong format.
I clean the jar cache before any test and delete the .java tree in home user too.
Now Im trying to know what is the item in webutil*.htm that load the keystore file to see the way that I can force the webutiljpi.htm to load the certificate.
Any idea?
Thanks for your interest and for your help.
Regards.
