i do not use Websphere6 but it looks like classloader problem WSIF 
(WSIFPluggableProviders.findPlugableProviders) tries to load 
com.ibm.wsif.providers.physicalrep.WSIFDynamicProvider_Physicalrep 
(possibly in other classloader) that references back WSIF 
(org/apache/wsif/base/WSIFServiceImpl) thatmay not accessible in that 
classloader ...try to change location of WSIF and whatever has 
com.ibm.wsif.providers.physicalrep to be as close as possible
