THIS IS A TEST INSTANCE. ALL YOUR CHANGES WILL BE LOST!!!!
JEST uses HTTP as communication protocol and HTTP URI as its command syntax.
A JEST URI introduces specific syntax rule on a standard URI to interpret the commands.
| Server Function | JEST URI |

uri := http://host[:port]/action/[qualifier]*['?'[parameter]'&'*]
qualifier := qualifier-key['='qualifier-value]
parameter := parameter-key'='parameter-value
action : denotes the JPA operation to be performed.
For example, find, query, insert, merge, remove, properties, domain etc.
qualifier : qualifies the action.
specific to the action, e.g. a query action can qualify with query/single to get a single result as in above ex09.
zero or more qualifier can be specified.
qualifier may have value separated by '='
each qualifier is separated by '/'
qualifier ordering is not significant (see above ex11.1 and ex11.2)
parameter : parameter for the action
For example, JPQL string is a parameter for a query action
zero or more parameter can be specified
parameter may have value separated by '='
each parameter is separated by '&'
first parameter can have special semantics based on action, e.g. first parameter for 'query' is JPQL string,
or first parameter for 'find' is the entity name, etc.
