HTTP server example

[Nobody/Anonymous]

hello

The project web page (http://xlloop.sourceforge.net/) has sample code of how to start a simple binary function server.  It says HTTP protocol is also supported but I don't see any example of how to start up a simple HTTP server.  In the .ini file section it explains how to configure the Excel client to work in HTTP mode.  But I don't see anything that explains how to start up an HTTP server.

Can you provide an example?

Thanks.

You start it as a Servlet in a server like Tomcat.  It's beyond the scope here to explain Servlets, but that's the key.

Following is the code I used to create an XLLoop servlet:

---

package com.mypackage;

import javax.servlet.*;

import org.boris.xlloop.handler.*;
import org.boris.xlloop.http.*;

public class MyFunctionServlet extends FunctionServlet
{
@Override
public void init(final ServletConfig config) throws ServletException
{
FunctionInformationHandler infoHandler = new FunctionInformationHandler();
MyFunctionHandler myHandler = new MyFunctionHandler();
infoHandler.add(myHandler.getFunctionInformation());
CompositeFunctionHandler compositeHandler = new CompositeFunctionHandler();
compositeHandler.add(infoHandler);
compositeHandler.add(myHandler);
setHandler(compositeHandler);
}
}

---

Here's an example of adding the new Servlet to the web.xml of tomcat:

<servlet>
<servlet-name>xlloopfunction</servlet-name>
<servlet-class>com..mypackage.MyFunctionServlet</servlet-class>
</servlet>
<servlet-mapping>
<servlet-name>xlloopfunction</servlet-name>
<url-pattern>/service/xlloopfunction</url-pattern>
</servlet-mapping>

Here is the xlloop.ini file I used with the Excel add-in:

protocol=http
url=http://localhost:8080/myapp/service/xlloopfunction

Thanks.  That's exactly what I was looking for.
