The configuration of the REST API consists in the deployment of jar libraries to the classpath and the configuration of the servlet in the
/WEB-INF/web.xml
.
After it's configured, all persistent classes are automatically exposed via RESTful HTTP interface.
DataNucleus REST API requires the libraries: DataNucleus core, DataNucleus rest,
Flexjson, and
the JDO API. These libraries must be in the classpath. In war files, these libraries are deployed under the folder
/WEB-INF/lib/
.
The DataNucleus REST Servlet class implementation is
org.datanucleus.rest.RestServlet
. It has to be configured in the
/WEB-INF/web.xml
file, and
it takes one initialisation parameter.
