public class MapRPCDroplet
This Servlet executes the RPC Command and renders its output paramter. Also sets the result parameter with output of the command execution. If an exception is generated by the command execution then an error parameter is rendered setting exception< parameter with the exception thrown.
Input parameters are passed into this droplet in different ways as following.
ServletException
is thrown when this happens. One exception to
this is if you want to set some default value for any parameters, you should
populate the Map property of this with default values and make an entry
for the key from the page context.
A complete description of the parameters to this droplet are:
inputProperties
Map property of the
droplet, and just pass the parameter names in this parameter. This droplet
parses the parameter names in this property and tries to get the value
for these parameters from the page. If any of the parameters is not found
in the page, this droplet looks for it in the inputProperties
Map property and populates the value of this parameter.
It is illegal to pass this parameter and inputParameters
to
the droplet. But it is legal to pass this parameter and setting the
inputProperties
in the properties of this droplet.
inputParameterNames
parameter.
inputParameterNames
page parameter to set default values to
some of the parameters.
The following is the sample code to use this droplet:
<droplet bean="/atg/integrations/MapRPCDroplet">
<param name="command" value="bean:/atg/integrations/jdbc/QueryForUser"/>
<param name="inputParameterNames" value="UserId">
<param name="UserId" value="bean:Profile.Id">
<java>/* a result DynamicBean put into the result /</java>
<oparam name="output">
The users email address is: <valueof param="result.emailAddress"/>
</oparam>
<oparam name="error">
Unable to execute query, the following exceptions occured: <valueof param="exception"/>
</oparam>
</droplet>
