servlets - how to properly call a java function from a ftl file in ofbiz? -

i think have done necessary splicing me allow gui invoke java method.

this ftl file process should start, on widget screens xml file , displaying contents i'm not sure of parameters used here proper call java class

<form action="<@ofbizurl>methodtoinvoke</@ofbizurl>" method="post">     <input type="submit" value="id"></input>     <input type="text" name="input"></input> </form> 

and code on controller

<request-map uri="methodtoinvoke">     <security https="true" auth="true"/>     <event type="java" path="com.report.someclass" invoke="methodtoinvoke"/>     <response name="success" type="view" value="reports" />     <response name="error" type="view" value="reports" /> </request-map> 

when run application , hit button, address on browser looks trying call method nothing seems happen. should download file user , have done setup on java method such reponse headers , file needs written on it.

when click on it not , goes same page.

with ofbiz controllers, can send response in 2 ways:

1. preffered more common way: in java event call services, or processing, result of processing request attribute, , render these attributes in view. can see, controller points view.
2. this less common case, when need send user data, cannot rendered in view, in case, manually write data in response object, , close reponse stream. assume doing that. in case should not return view in controller, because have written data , closed response stream. change controller this:

<response name="success" type="none" />
