1). Setup a BW SSL project. Enable SSL debug tracing and search for "Cipher Suites" :
java.property.TIBCO_SECURITY_VENDOR=j2se
java.property.javax.net.debug=ssl,handshake,record
You should see the client list supporting "Cipher Suites" in ClientHello. In ServerHello, you should see the "Cipher Suites" server has chosen to communicate with the client.
2). Test with SOAPUI as client. Set the following in soapui.bat:
set JAVA_OPTS=-Xms128m -Xmx1024m -Djavax.net.debug=ssl,handshake,record -Dsoapui.https.ciphers=SSL_RSA_WITH_RC4_128_SHA -Dsoapui.properties=soapui.properties "-Dsoapui.home=%SOAPUI_HOME%\"
If "SSL_RSA_WITH_RC4_128_SHA" is not supported by BW, you would see the attached error message (Filename: CipherNoMatchError.txt), which shows that the client only supports {Cipher Suites: [SSL_RSA_WITH_RC4_128_SHA]}.
The BW server process reports { javax.net.ssl.SSLHandshakeException: no cipher suites in common} and "SEND TLSv1 ALERT: fatal, description = handshake_failure".
