如何从ofbiz的ftl文件中正确调用java函数？(how to properly call a java function from a ftl file in ofbiz?)

 我想我已经为我做了必要的拼接，允许gui调用java方法。 
 
 这是我的ftl文件，其中进程应该开始，这是在小部件屏幕xml文件上，它正确显示内容，但我只是不确定我在这里用来正确调用java类的参数 
 
<form action="<@ofbizUrl>methodToInvoke</@ofbizUrl>" method="POST">
    <input type="submit" value="id"></input>
    <input type="text" name="input"></input>
</form>
 
 这是我控制器上的代码 
 
<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>
 
 当我运行应用程序并按下按钮时，我的浏览器上的地址似乎试图调用该方法，但似乎没有任何事情发生。 它应该下载一个文件给用户，我已经完成了java方法的设置，例如响应头和需要在其上写的文件。 
 
 当我点击它时它并没有真正做任何事情，它只是回到同一页面。 

I think I have already done the necessary splicing for me to allow the gui to invoke a java method.
 
This is my ftl file where the process should start, this is on a widget screens xml file and it is properly displaying the contents but i'm just not sure of the parameters that I used here to do a proper call to the java class
 
<form action="<@ofbizUrl>methodToInvoke</@ofbizUrl>" method="POST">
    <input type="submit" value="id"></input>
    <input type="text" name="input"></input>
</form>
 
and this is the code on my 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 I run the application and I hit the button, the address on my browser looks to be trying to call the method but nothing seems to happen. it should download a file to the user and I have already done the setup on the java method such as the reponse headers and the file that needs to be written on it.
 
When I click on it it does not really do anything and it just goes back to the same page.
