Sometimes users experience the following error when opening a file from an HTTPS link:
"Server SSL error
The server you are connecting to does not have a valid certificate from an authorised authority".

This happens if the server certificate is not issued by certification authority, and it is self signed or issued by a private CMS.

If you trust the server, you can add the server certificate to your trusted Java key store, and allow Omniscope to use it as trusted and verified certificate.

The cause of the problem and solution are both well explained in this article.

Here are the steps to allow Omniscope to recognise and use your server certificate:

1. Use InstallCert tool
   - Get the InstallCert.java file from http://code.google.com/p/java-use-examples/source/browse/trunk/src/com/aw/ad/util/InstallCert.java
   - Compile the file using the "javac" command:
   javac InstallCert.java
   
   
2. Add your server certificate
   - Run InstallCert, with the server hostname and https port (if available), then press “1” when ask for input:
   java InstallCert myserver.com:8080
   - Check the process has finished and generated a file named “jssecacerts“ in the same folder you run the InstallCert tool.
   
   
3. Launch Omniscope with JVM parameter
   - See "Additional JVM arguments" here http://www.visokio.com/kb/installconfig .
   - Update your installconfig.properties file to have the following line:
   ADDITIONAL_JVM_ARGS=-Djavax.net.ssl.trustStore=c:\yourFolder\jssecacerts
   - Start Omniscope.
   

For the sake of simplicity, please find attached a zip file with the 2 InstallCert tool classes already compiled and ready to run.
