Hi Charles,
You can leave the "com.sun.jersey.config.property.classpath" property
as is and add "com.sun.jersey.property.packages" init parameter to add
your application
packages to the configuration:
<init-param>
<param-name>com.sun.jersey.config.property.packages</param-name>
<param-value>your.app.pkg</param-value>
</init-param>
another option would be to add your application classes directly, so
that you save
the time needed for scanning:
<init-param>
<param-name>com.sun.jersey.config.property.classnames</param-name>
<param-value>your.app.pkg.Res1, your.app.pkg.Res2</param-value>
</init-param>
Would this be sufficient?
Or you need to have both JSON providers active at the same time within a
single application?
Each processing a distinct set of classes?
