I am using Tomcat 4.1.18 with IBM SDK 1.4.0. When I have the SSL connector enabled in server.xml, I can't start Tomcat. I get the following error: java.lang.NoClassDefFoundError: com/sun/net/ssl/internal/ssl/Provider In the server.xml I am using the following for the SSL connector: <!-- Define a SSL Coyote HTTP/1.1 Connector on port 8443 --> <Connector className="org.apache.coyote.tomcat4.CoyoteConnector" port="8443" minProcessors="5" maxProcessors="75" enableLookups="true" acceptCount="100" debug="0" scheme="https" secure="true" useURIValidationHack="false" disableUploadTimeout="true"> <Factory className="org.apache.coyote.tomcat4.CoyoteServerSocketFactory" clientAuth="false" protocol="TLS" keystoreFile="conf\keystore" keystorePass="xxxxxxxx"/> I have replaced the actual keystore password with xxxxxxxx above. Since the IBM SDK 1.4.0 uses the IBM JSSE the following is in my java.security file: security.provider.1=com.ibm.jsse.IBMJSSEProvider security.provider.2=com.ibm.crypto.provider.IBMJCE security.provider.3=com.ibm.security.jgss.IBMJGSSProvider security.provider.4=com.ibm.security.cert.IBMCertPath I have found that the SSL connector works fine when using the IBM SDK 1.3.1 with the Sun JSSE 1.0.3. In this case my java.security file contains: security.provider.1=sun.security.provider.Sun security.provider.2=com.sun.net.ssl.internal.ssl.Provider Does anyone know if there is a way to configure Tomcat to use the IBM SDK with the IBM JSSE for the SSL connector. I have also tried this with Tomcat 4.0.4 with the same results. I looked at the source for Tomcat 4.0.6 and found the following in SSLServerSocketFactory.java that makes me think that Tomcat can only work with the Sun JSSE: /** * The name of our protocol handler package for the "https:" protocol. */ private static final String PROTOCOL_HANDLER = "com.sun.net.ssl.internal.www.protocol"; /** * The name of the system property containing a "|" delimited list of * protocol handler packages. */ private static final String PROTOCOL_PACKAGES = "java.protocol.handler.pkgs"; /** * The configured socket factory. */ private javax.net.ssl.SSLServerSocketFactory sslProxy = null; I really would like to find a way to use the IBM JSSE if possible. Any help would be greatly appreciated. John A. Campbell IBM Sales and Distribution zSeries Advanced Technical Support 800 N.
