REST API:exec Resource

Provides the ability to execute a class method using the REST API.

Considerations

• A Class must be defined. (The exec resource invokes a method in the class.)
• An instance of the class is created automatically, so the method need not be static.

• Signatures:
  • The method must be public
  • The method can either take no arguments: public methodName()
  • Or it take arguments passed in a Map: public methodName(Map params)
    (Parameters passed in the Request are wrapped in a Map, and passed to the method.)

• Return Types:
  • A method may return void.
  • If the return type is a Map, it can be used to return key-value pairs.
  • Otherwise the return value is automatically converted to a string using result.toString()

Request

<platform>
    <execClass>
        <clazz>fully.qualified.JavaClassName</clazz>
        <method>methodName</method>
        ...optional list of parameter tags, like these:...
        <firstName>Peter</firstName>
        <lastName>Smith</lastname>
    </execClass>
</platform>

Response

The output structure is the same, except that the key/value pairs are those returned by the class method, when the return value is a Map. When the return value is converted to a string, the response looks like this:

<platform>
    <execClass>
        <result>...result-string here...</result>
    </execClass>
    <message>
        <code>0</code>
        <description>Success</description>
    </message>
</platform>

Known issue

Null return values are not handled at this time.
