Liferay+Apache Tomcat+SSL+CA certificate [CIPHERS PROBLEM]

Hi guys,

well let me explain my problem. I use Liferay 5.2.3 bundled with Apache Tomcat 5.5.27. The whole portal uses HTTPS and till today I was using a self-signed certificate without any problem. So now I got a Verisign CA certificate and I wanted to install it on my Tomcat.
I imported successfully using keytool the certification on keystore. Then I started Tomcat, I noticed that port 443 (that I use) was listening as it should but I couldn't access to the website. I got an error "SSL handshake errorjavax.net.ssl.SSLException: No available certificate or key corresponds to the SSL cipher suites which are enabled."

This is the relevant part of my server.xml file (it is just the latest version...):

<!-- Define a SSL HTTP/1.1 Connector on port 8443 -->
<Connector port="443" maxHttpHeaderSize="8192"
maxThreads="150" minSpareThreads="25" maxSpareThreads="75" enableLookups="true" disableUploadTimeout="true" address="82.103.132.56" acceptCount="100" scheme="https" secure="true" ciphers="TLS_KRB5_WITH_RC4_128_MD5,TLS_KRB5_WITH_3DES_EDE_CBC_MD5,
TLS_KRB5_WITH_DES_CBC_MD5,TLS_KRB5_EXPORT_WITH_RC4_40_MD5,
TLS_KRB5_EXPORT_WITH_DES_CBC_40_MD5" clientAuth="false" sslProtocol="TLS"
keystoreFile="/tomcat-ssl/my.kdb" keystorePass="changeit" keystoreType="JKS"/>



The following is the catalina log:
