java - Cipher suite not available - how to add/enable? Tomcat SSL -

i have list of enabled , supported ciphers in java

-----------supported ciphers------------- supported cipher suites: ssl_dhe_dss_export_with_des40_cbc_sha ssl_dhe_dss_with_3des_ede_cbc_sha ssl_dhe_dss_with_des_cbc_sha ssl_dhe_rsa_export_with_des40_cbc_sha ssl_dhe_rsa_with_3des_ede_cbc_sha ssl_dhe_rsa_with_des_cbc_sha ssl_dh_anon_export_with_des40_cbc_sha ssl_dh_anon_export_with_rc4_40_md5 ssl_dh_anon_with_3des_ede_cbc_sha ssl_dh_anon_with_des_cbc_sha ssl_dh_anon_with_rc4_128_md5 ssl_rsa_export_with_des40_cbc_sha ssl_rsa_export_with_rc4_40_md5 ssl_rsa_with_3des_ede_cbc_sha ssl_rsa_with_des_cbc_sha ssl_rsa_with_null_md5 ssl_rsa_with_null_sha ssl_rsa_with_rc4_128_md5 ssl_rsa_with_rc4_128_sha tls_dhe_dss_with_aes_128_cbc_sha tls_dhe_rsa_with_aes_128_cbc_sha tls_dh_anon_with_aes_128_cbc_sha tls_empty_renegotiation_info_scsv tls_krb5_export_with_des_cbc_40_md5 tls_krb5_export_with_des_cbc_40_sha tls_krb5_export_with_rc4_40_md5 tls_krb5_export_with_rc4_40_sha tls_krb5_with_3des_ede_cbc_md5 tls_krb5_with_3des_ede_cbc_sha tls_krb5_with_des_cbc_md5 tls_krb5_with_des_cbc_sha tls_krb5_with_rc4_128_md5 tls_krb5_with_rc4_128_sha tls_rsa_with_aes_128_cbc_sha -----------enabled ciphers--------------- enabled cipher suites: ssl_dhe_dss_export_with_des40_cbc_sha ssl_dhe_dss_with_3des_ede_cbc_sha ssl_dhe_dss_with_des_cbc_sha ssl_dhe_rsa_export_with_des40_cbc_sha ssl_dhe_rsa_with_3des_ede_cbc_sha ssl_dhe_rsa_with_des_cbc_sha ssl_rsa_export_with_des40_cbc_sha ssl_rsa_export_with_rc4_40_md5 ssl_rsa_with_3des_ede_cbc_sha ssl_rsa_with_des_cbc_sha ssl_rsa_with_rc4_128_md5 ssl_rsa_with_rc4_128_sha tls_dhe_dss_with_aes_128_cbc_sha tls_dhe_rsa_with_aes_128_cbc_sha tls_empty_renegotiation_info_scsv tls_rsa_with_aes_128_cbc_sha

however cipher need available

tls_rsa_with_aes_256_cbc_sha.

i obtained info writing quick java class runs getsupportedciphersuites() , getenabledciphersuites(), have run on jre 6 32 , 64 bit , on jre 7 32 , 64 bit, due systems working with, have run 32 bit jre. cannot find online other list of ciphers should supported http://docs.oracle.com/javase/7/docs/technotes/guides/security/sunproviders.html

this link shows cipher looking available after checking don't see available me. question is, there way add together cipher in or different version of java can utilize have available? also, how can supported not enabled enabled?

as note, have files located here installed java 6: http://www.oracle.com/technetwork/java/javase/downloads/jce-6-download-429243.html , here java 7: http://www.oracle.com/technetwork/java/javase/downloads/jce-7-download-432124.html . had files , overwrote them anyway files downloaded links. did not help.

this lead working tomcat in eclipse. when trying run tomcat working certificate this: java.io.ioexception: ssl configuration invalid due no available certificate or key corresponds ssl cipher suites enabled.

while point alias not beingness stated, in situation believe problem related cipher.

i start using legion of bouncy castle, , per directions here triple check that

be careful if using windows jdk install install jre , jdk in 2 separate places - both of these need have policy files installed in it.
