This artifact is an OpenCMIS Client Bindings Jar that only works on IBM WebSphere 7.0.0.5 and later. It takes advantage of the JAX-WS implementation provided by WebSphere, reduces OpenCMIS’ dependencies and avoids potential conflicts with the Suns JAX-WS implementation that is usually required for OpenCMIS. In order to use the OpenCMIS client library in a web application on WebSphere, place the following jars into /WEB-INF/lib : chemistry-opencmis-client-api-.jar chemistry-opencmis-client-impl-.jar chemistry-opencmis-client-binding-websphere-.jar chemistry-opencmis-commons-api-.jar chemistry-opencmis-commons-impl-.jar slf4j-api-1.6.x.jar Other dependencies mentioned in other parts of the OpenCMIS documentation are not required. Make sure that the default OpenCMIS Client Bindings Jar is not present.
