Modifying OpenSSL to specify allowed cipher suites and protocols can be done in the Resin application server configuration file, resin.xml, in the <openssl> block.

conf/resin.xml

<resin xmlns="http://caucho.com/ns/resin">
...
<cluster id="web-tier">
<server id="...">

<http port="443">
  ...
  <openssl>
    <certificate-key-file>keys/your_domain.key</certificate-key-file>
    <certificate-file>keys/your_domain.crt</certificate-file>        
    <certificate-chain-file>keys/chain.txt</certificate-chain-file>
    <password>test123</password>
    <cipher-suite>ALL:!aNULL:!ADH:!eNULL:!LOW:!EXP:RC4+RSA:+HIGH:+MEDIUM</cipher-suite>
    <protocol>-all +sslv3 +tlsv1</protocol>   
  </openssl>
</http>

</server>

Typically this is required for website PCI compliance.
