Using servlets in module development

Module Development
1

Hello all!

There are a couple of posts on the forums regarding servlets but none seem to answer this problem:

I am trying to load a html into a servlet following these steps:

1.- Adding the servlet into the gateway in GatewayHook::setup :

getGatewayContext().getWebResourceManager().addServlet("/REPORTING", ReportHTMLServlet.class);

2.- Creating the ReportHTMLServlet class:

public class ReportHTTPServlet extends HttpServlet {

    @Override
    protected void doGet(HttpServletRequest req, HttpServletResponse resp) throws ServletException, IOException {
        try{
             String message = GatewayHook.PRResources.toString();
             req.setAttribute("atribute1",message);
             req.getRequestDispatcher("/WEB-INF/report.html").forward(req,resp);
        }catch (Exception e){

        }
    }
}

3.- Creating an html in the module path “mymodule/src/main/WEB-INF/report.html”:

<!DOCTYPE html>
<html lang="en">
<head>
    <meta charset="UTF-8">
    <title>This is a report!</title>
</head>
<body>
    <p>Sample: ${attribute1}</p>
</body>
</html>

What am I missing? Do I need to add de @addServlet annotation into the servlet class? Is the html path wrong? Do I need a gateway restart? Maybe wrong aproach :slight_smile: ?

The url would be ip:port/main/REPORTING.

Thanks!

EDIT: Do I need to use gatewayHook::moutRouteHandlers, adding a route with the html in it? Which datatype would it be?
