Samebug tips

,

you should add @JsonIgnoresProperties, This allows properties not defined in your POJO to be ignored. Needed if you are just trying to gamble your way through few properties in JSON. you do this by @JsonIgnoreProperties(property=true)

,

You need to define another class for the information within ResObj {"ClientNum":"12345","ServerNum":"78945","IdNum":"020252"}. Otherwise jackson cannot determine how to deserialize.
