In order to do wss4j logging you need this: http://www.slf4j.org/manual.html "To switch logging frameworks, just replace slf4j bindings on your class path. For example, to switch from java.util.logging to log4j, just replace slf4j-jdk14-1.7.7.jar with slf4j-log4j12-1.7.7.jar."
While cxf picks META-INF/cxf/org.apache.cxf.Logger it doesn't impact wss4j in any way. Replacing this jar did the trick. Can check if removing META-INF/cxf/org.apache.cxf.Logger will work for both. also added System.setProperty("log4j.configuration","log4j.properties"); - not required most likely unless you move the file to some specific folder. 2014-11-26 10:01:39 DEBUG WSProviderConfig:346 - The provider STRTransform was added at position: 10 2014-11-26 10:01:39 DEBUG WSProviderConfig:346 - The provider STRTransform was added at position: 10 2014-11-26 10:01:39 DEBUG WSProviderConfig:346 - The provider STRTransform was added at position: 10 2014-11-26 10:01:39 DEBUG WSProviderConfig:346 - The provider AttachmentContentSignatureTransform was added at position: 11 2014-11-26 10:01:39 DEBUG WSProviderConfig:346 - The provider AttachmentContentSignatureTransform was added at position: 11 2014-11-26 10:01:39 DEBUG WSProviderConfig:346 - The provider AttachmentContentSignatureTransform was added at position: 11 2014-11-26 10:01:39 DEBUG WSProviderConfig:346 - The provider AttachmentCompleteSignatureTransform was added at position: 12 2014-11-26 10:01:39 DEBUG WSProviderConfig:346 - The provider AttachmentCompleteSignatureTransform was added at position: 12 2014-11-26 10:01:39 DEBUG WSProviderConfig:346 - The provider AttachmentCompleteSignatureTransform was added at position: 12 2014-11-26 10:01:39 DEBUG ResourceResolver:247 - Registered resolver: org.apache.wss4j.dom.resolvers.ResolverAttachment@1cdfd19 2014-11-26 10:01:39 DEBUG ResourceResolver:247 - Registered resolver: org.apache.wss4j.dom.resolvers.ResolverAttachment@1cdfd19 2014-11-26 10:01:39 DEBUG WSS4JResourceBundle:52 - Can't find bundle for base name org/apache/xml/security/resource/xmlsecurity, locale pl_PL 2014-11-26 10:01:39 DEBUG WSS4JResourceBundle:52 - Can't find bundle for base name org/apache/xml/security/resource/xmlsecurity, locale pl_PL 2014-11-26 10:01:39 DEBUG WSS4JResourceBundle:52 - Can't find bundle for base name org/apache/xml/security/resource/xmlsecurity, locale pl_PL 2014-11-26 10:01:39 DEBUG Init:111 - Registering default algorithms 2014-11-26 10:01:39 DEBUG Init:111 - Registering default algorithms 2014-11-26 10:01:39 DEBUG WSProviderConfig:271 - The provider ApacheXMLDSig - 2.02 was added at position: 2 2014-11-26 10:01:39 DEBUG WSProviderConfig:271 - The provider ApacheXMLDSig - 2.02 was added at position: 2 2014-11-26 10:01:39 DEBUG WSProviderConfig:271 - The provider ApacheXMLDSig - 2.02 was added at position: 2 2014-11-26 10:01:39 DEBUG WSProviderConfig:271 - The provider BC - 1.51 was added at position: 2 2014-11-26 10:01:39 DEBUG WSProviderConfig:271 - The provider BC - 1.51 was added at position: 2 2014-11-26 10:01:39 DEBUG WSProviderConfig:271 - The provider BC - 1.51 was added at position: 2 Full debug with WSProviderConfig entries: http://pastebin.com/8Z4ueYn7 -- View this message in context: http://cxf.547215.n5.nabble.com/possible-wss4j-bug-tp5750539p5751483.html Sent from the cxf-user mailing list archive at Nabble.com.
