javax.xml.ws.WebServiceException: Provider com.sun.xml.internal.ws.spi.ProviderImpl not found

Question

I'm trying to run a webservice client on jdk1.5 and gives me the following error:

javax.xml.ws.WebServiceException: Provider com.sun.xml.internal.ws.spi.ProviderImpl not found

Any suggestion will be appreciated.

Answer 1

Make sure that on your path you can find also the jar containing the class com.sun.xml.internal.ws.spi.ProviderImpl. I checked what jar might be needed and here you can see the jars containing the given class. Any of them might help you.

Answer 2

I don't know exact reason why it can not find the right class but I think it is some problem with (or feature of) Java class loader in Oracle database when it looks for resources.

I loaded JAX-WS reference implementation from java.net with all its dependencies with the SYS user (with the public access permissions and public synonyms). But the classes generated from service WSDL I loaded to user SCOTT schema. And for some reason when SCOTT runs procedures that uses service, javax.xml.ws.spi.FactoryFinder does look up for implementation name in META-INF/services/javax.xml.ws.spi.Provider resource (which have correct value com.sun.xml.ws.spi.ProviderImpl) but can not find this resource so tries to load provider from hard-coded class name (com.sun.xml.internal.ws.spi.ProviderImpl) and fails.

Solution for me was to load all META-INF/services/* files from all the JAX-WS RI and dependencies jar's to SCOTT schema. Alternative way could be to load all JAX-WS RI, dependencies and final program to the same schema.
