TLS v1.2 on old Java 5 and Tomcat 5.x

Question

I have an old Java 5 application running on a Tomcat 5 server. I tried everything suggested to implement the TLS v1.2 protocol yet nothing worked and the browser will return a ERR_SSL_VERSION_OR_CIPHER_MISMATCH error. As of now what I tried is:

1. Configuring the Server.xml

   <Connector ... sslEnabledProtocols = "TLSv1.2">

2. Updating the jre to Java 1.7

3. Adding to the optional jvm arguments

   -Dhttps.protocols=TLSv1.2

Beside upgrading Tomcat to a newer version, what can I do?
