XSD TO JAVA

Simple proof of concept for converting XSD schemas into pure Java classes at runtime and by using reflection. It can be improved to, for example, build intelligent JAX-RS console or GUI clients without knowledge of the domain model, by querying application.wadl and looking for the schema. The classes are transpiled, compiled and appended to the path at runtime so they are always updated. Other things missing is fetching the schema from network instead of a file, not depending on JXC and Javax Tools, building a schema and creating an automatic CLI client for it, between other tree of possibilities.

1. After installing mitmproxy run it (just type mitmproxy) in a terminal session and quit. This will create the necessaries certificates files at ~/.mitmproxy.

2. Extract the certificate to .crt format:
   openssl x509 -in ~/.mitmproxy/mitmproxy-ca.pem -inform PEM -out ca.crt

3. Trust the certificate into CA:
   sudo trust anchor ca.crt

4. Run the mitmproxy again
