The source code of the XKMS Responder package (https://joinup.ec.europa.eu/software/peppol/release/110) do not compile.
The missing classes (in the importexport) seems to be generated by JAXB, but there is no build script nor XSD schema provided.
Also, the resources (CSS, Logo) are missing from the source.
Can you provide missing classes and/or build script?
