How to make my browser trust my server certificate?

I made my TOMCAT run on https using http://www.mkyong.com/tomcat/how-to-configure-tomcat-to-support-ssl-or-https/

When I open https://localhost:8443/, it gives me a red colored page warning me, that the server certificate is not trusted by google chrome (that was expected).

Now, I want to make my google chrome trust the server certificate. I generated mkyong.cer file using keytool -export command

and then I tried to import it in client's trust store as follows.

(clientTrustStore.key is the output file, and mkyong.cer is the input file.)

I took reference of http://db.apache.org/derby/docs/dev/adminguide/cadminsslkeys.html for import command.

C:\>keytool -import -alias mkyong -file mkyong.cer -keystore clientTrustStore.key
Enter keystore password:
Re-enter new password:

Version: 3
Trust this certificate? [no]: yes
Certificate was added to keystore

Even after this, I am still getting that warning when i open https://localhost:8443/

Can someone please explain this behavior, or if I am doing something wrong?

Here's the first link I got when I googled your question: http://groups.google.com/a/googleproductforums.com/forum/#!topic/chrome/1b7V3cs7BS4. It appears to me that the answer given there is "Use Internet Explorer to make it trusted and then Chrome will automatically trust it", but you can read the whole thread which does contain more information than just that.

Thanks Paul for taking out some time and answering.

I have researched on net and studied something about this.

I have created one post from my understanding and observation.

Might help someone
