SSL with signed jar

[Anestis Sismanidis]

Hello! If you are bored to read, just read the question an the end.

After a lot of effort I have managed to connect to MySQL with SSL like this:

java
-Djavax.net.ssl.keyStore=mykeystore
-Djavax.net.ssl.keyStorePassword=mykeystorepassword
-Djavax.net.ssl.trustStore=mytruststore
-Djavax.net.ssl.trustStorePassword=mytruststorepassword
-cp myapp.jar com.myapp.Main

But this way, mykeystore is exposed. Anyone could just take it and connect to my server. Am I missing something?

I tried to sign my jar with the keystore and connect like this:

java
-Djavax.net.ssl.trustStore=mytruststore
-Djavax.net.ssl.trustStorePassword=mytruststorepassword
-cp myapp.jar com.myapp.Main

but it failed.

The question:

Is there a way to connect to MySQL (using SSL) through a signed jar? Have you done it?

Thanks.
