| | | Should classloader at handler stage find jars in the service 's WEB-INF/lib ? | Should classloader at handler stage find jars in the service 's WEB-INF/lib ? 2007-08-07 - By Karen Loughran

Hi all,
My web service code makes a call to a service which returns a SAML assertion
(serialised with XStream) and this works fine.
However, if I move this call to my security handler code (WSCredentialReceiver
extended from wss4j) configured in requestFlow within the server-config.wsdd
(of the same service) I get the CannotResolveClassException exception from
XStream when its trying to deserialise it (full error below).
opensaml.jar (which contains SAMLAudienceRestrictionCondition) IS in the
WEB-INF/lib directory of my service. Shouldn't the classloader to be able to
see all jars in the service's WEB-INF/lib at the handler stage ?
Do I need an extra parameter settings in the wsdd for this ?
The relevant snippet of my server-config.wsdd looks like this:
....
<service name="publication" provider="java:RPC" use="literal" style="document"
>
<parameter name="className"
value="uk.ac.besc.prism.publication.impl.publication"/>
<wsdlFile>/wsdl/publication.wsdl</wsdlFile>
<parameter name="allowedMethods" value="*"/>
<requestFlow>
<handler type="SecurityInboundHandler"/>
</requestFlow>
<responseFlow>
<handler type="IntegrityEnforcementHandler"/>
</responseFlow>
</service>
....
<handler name="SecurityInboundHandler"
type="java:uk.ac.besc.prism.std.utils.impl.WSCredentialReceiver">
<parameter name="action" value="Signature"/>
<parameter name="signaturePropFile" value="crypto.properties"/>
<parameter name="passwordCallbackClass"
value="com.eoveri.std.ws.PWCallback"/>
<parameter name="signatureKeyIdentifier" value="DirectReference" />
</handler>
I have tested it with with tomcat 5.x and tomcat 6.0.13, but the same error
occurs,
Any help would be much appreciated,
Thanks
