首先，WAS用IBM JSSE，不支持Sun JSSE，有文檔說明。
http://www-01.ibm.com/support/docview.wss?uid=swg21418924
然后，你要檢查
1） WAS\java\jre\lib\security\java.security, 看看secrity provider list里是否有Sun JSSE
# List of providers and their preference orders (see above):
#
#security.provider.1=com.ibm.crypto.fips.provider.IBMJCEFIPS
security.provider.1=com.ibm.crypto.provider.IBMJCE
security.provider.2=com.ibm.jsse.IBMJSSEProvider
security.provider.3=com.ibm.jsse2.IBMJSSEProvider2
security.provider.4=com.ibm.security.jgss.IBMJGSSProvider
security.provider.5=com.ibm.security.cert.IBMCertPath
security.provider.6=com.ibm.crypto.pkcs11impl.provider.IBMPKCS11Impl
security.provider.7=com.ibm.security.cmskeystore.CMSProvider
security.provider.8=com.ibm.security.jgss.mech.spnego.IBMSPNEGO
security.provider.9=com.ibm.security.sasl.IBMSASL
security.provider.10=com.ibm.xml.crypto.IBMXMLCryptoProvider
security.provider.11=com.ibm.xml.enc.IBMXMLEncProvider
security.provider.12=org.apache.harmony.security.provider.PolicyProvider
2） 類路徑里是否有Sun JSSE 的jar包
3）你的代碼里是否有調用Sun JSSE provider |
