The j2eeLib.getRequestAttr() system function uses a specified key to retrieve a value from request scope storage.
If a value is not found with the specified key, the function returns a null value. If the retrieved value is the wrong type, EGL throws a J2EESessionRequestAccessException.
You can place a value in request scope storage by using the j2eeLib.setRequestAttr() system function. The value placed in the servlet's request scope storage is available as long as the servlet request is valid. Submitting a form from a page creates a new request.
j2eeLib.getRequestAttr() is overloaded, which means that you can call the same function name with different configurations of parameters and return values. The first form below, with a single parameter, is preferred; the second form, with two parameters, is maintained for backward compatibility.
j2eeLib.getRequestAttr( key STRING in) returns (value ANY)
or
j2eeLib.getRequestAttr( key STRING in, value ANY inOut)
