Hello, I'm runnig xwiki-enterprise-web-1.3.2 in a WebSphere Application Server 6.1. I'm trying to use the ldap authentication but I get the following exception: [4/30/08 12:20:56:890 CEST] 0000006d SystemErr R Caused by: java.lang.NoClassDefFoundError: com.sun.net.ssl.internal.ssl.Provider at java.lang.J9VMInternals.verifyImpl(Native Method) at java.lang.J9VMInternals.verify(J9VMInternals.java:68) at java.lang.J9VMInternals.initialize(J9VMInternals.java:129) at com.xpn.xwiki.user.impl.LDAP.XWikiLDAPAuthServiceImpl.ldapAuthenticate(XWikiLDAPAuthServiceImpl.java:160) at com.xpn.xwiki.user.impl.LDAP.XWikiLDAPAuthServiceImpl.authenticate(XWikiLDAPAuthServiceImpl.java:107) This is caused by the missing com.sun.net.ssl.internal.ssl.Provider class in the IBM JVM. I have had a look on the code and I saw that the com.xpn.xwiki.plugin.ldap.XWikiLDAPConnection is creating a com.sun.net.ssl.internal.ssl.Provider instance in static way: Security.addProvider(new Provider()); A strong coupling between the application and the JVC implementation is the consequence. A possible solution can be: create the provider dynamically using a configuration variable: try { ClassLoader cl = Thread.currentThread().getContextClassLoader(); String className = config.getLDAPParam("ldap_ssl_provider", "com.sun.net.ssl.internal.ssl.Provider", context); java.security.Provider provider = (java.security.Provider) cl.loadClass(className) .newInstance(); Security.addProvider(provider); } catch (Exception e) { throw new XWikiLDAPException("LDAP bind failed loading security provider " + className, e); } Marco Marini Unicredit Global Information Serivecs SpA Application Architectures and Development Application Architectures Application Integration and Framework Via Monte Bianco, 18 - 37132 Verona Tel. +39 045 808 4518 Mobile +39 335 1993 954 Fax +39 045 808 4599 marco.marini(a)unicreditgroup.eu This e-mail is confidential and may also contain privileged information.
