Christopher Lane Hinson (w/ Web Performance) commented on JCLOUDS-881:
----------------------------------------------------------------------
I added the GoogleAppEngineConfigurationModule, but to no effect. From a
cursory reading, that module seems to be about threading and HTTP handlers, not
reflection.
GAE docs say: An application is allowed full, unrestricted, reflective access
to its own classes. . . . An application can also reflect on JRE and API
classes, such as java.lang.String and javax.servlet.http.HttpServletRequest.
However, it can only access public members of these classes, not protected or
private.
Would it be a lot of work to bring jclouds into compliance with that? Is it
something we could facilitate? I can't promise anything, but all of our options
involve non-trivial time and effort, so I could make an argument for some kind
of contribution on our part.

> Key: JCLOUDS-881
> URL: https://issues.apache.org/jira/browse/JCLOUDS-881
> Project: jclouds
> Issue Type: Bug
> Affects Versions: 1.8.1, 1.9.0
> Environment: Google App Engine SDK 1.9.18; Java 1.8.0_05; Eclipse
> Luna; Windows 8.1 (could not replicate on same codebase running in Debian
> GNU/Linux; GAE 1.9.17; Java 1.7.0_65.)
> Reporter: Christopher Lane Hinson (w/ Web Performance)
>
> Hi, I'm writing on the understanding that you hope JClouds will work in a
> Google App Engine environment, where I'm having the problem described below.
> I'm having a hard time understanding how anyone can use the aws-ec2 provider
> in GAE at all under these conditions. Either I'm failing at something
> elementary, or everyone else lined up for this issue hasn't upgraded to the
> problematic version of something yet.
> Thanks in advance for your assistance.
> (1) Create a new Google App Engine project using the tools in Eclipse.
> (2) Use the following as your servlet:
> package com.webperformance.bugs.jclouds;
> import java.io.IOException;
> import javax.servlet.http.*;
> import org.jclouds.ContextBuilder;
> import org.jclouds.aws.ec2.AWSEC2Api;
> import org.jclouds.compute.ComputeServiceContext;
> @SuppressWarnings("serial")
> public class Jclouds_app_engine_bugServlet extends HttpServlet {
> public void doGet(HttpServletRequest req, HttpServletResponse resp)
> throws IOException {
>
> ComputeServiceContext context =
> ContextBuilder.newBuilder("aws-ec2")
> .credentials("my valid access key", "my valid
> secret key")
> .buildView(ComputeServiceContext.class); //
> <<---- explodes here
> AWSEC2Api ec2Api = context.unwrapApi(AWSEC2Api.class);
> /* //tried this instead, same thing
> AWSEC2Api ec2Api = ContextBuilder.newBuilder("aws-ec2")
> .credentials(data._access_key, data._secret_key)
> .buildApi(AWSEC2Api.class);
> */
>
> resp.setContentType("text/plain");
> resp.getWriter().println("Hello, world");
> }
