Did you modify any files from samples/helloworld?
What do you get when you type goapp version?

No. I have not modified any of the files. My goapp version is go version go1.4.2 (appengine-1.9.26) windows/386

I just ran the example on my Windows box using windows/amd64, and it worked:

So it looks like either this is a windows/386 issue or something is not right on your system.
I'll now try windows/386.

I just tested the windows/386 version, and it worked for me too, so I think something may be wrong with your installation or with your Windows box. Can you please try re-installing and/or try another Windows box?

I will install everything and try again. Thanks.

I re-installed everything on my Windows 7 32-bit box (I have been using Go on this box since 2013 and have never ever faced any problems).
I still get the same 2 errors.
Here's my configuration:
GOARCH=386
GOOS=windows
GOPATH=G:\go_projects\go
GOROOT=G:\go
Path=G:\Python27;G:\go\bin;G:\go_projects\go\bin;G:\go_appengine;G:\Google\Cloud_ SDK\google-cloud-sdk\bin;
Go Workspace:
Versions:
Go - go version go1.5.1 windows/386
Python - 2.7.8
goapp - go version go1.4.2 (appengine-1.9.26) windows/386
As suggested by Jason Buberel:
Google Cloud SDK 0.9.78
bq 2.0.18
bq-win 2.0.18
core 2015.09.11
core-win 2015.08.10
gcloud 2015.09.11
gsutil 4.15
gsutil-win 4.13
windows-ssh-tools 2015.06.02
Unluckily, I don't have another Windows box and can't reinstall Windows on the existing one.
I am stuck, I guess :)

I just re-solved the issue!
The error "panic: endpoints: "GreetingService" has no exported methods of suitable type" made me look at the code of service.go for 3 days -
https://github.com/GoogleCloudPlatform/go-endpoints/blob/master/endpoints/service.go
I had already installed endpoints in April of this year. So was the problem being created since I had an earlier version of service.go?
It made sense to update the same.
The documentation says:
Add “-u” param to get an updated version, i.e.
go get -u github.com/GoogleCloudPlatform/go-endpoints/endpoints
Now, you’ll see a couple errors, which is OK, don’t worry!
That's it! The problem got resolved.
Does golang have something that keeps all packages/libraries up-to-date?

I'm glad you found the problem. There are a number of 3rd-party vendoring solutions, but I don't know of anything that updates all your packages. That actually sounds like a potentially dangerous operation anyway.

go get -u ... should update all of your packages :)

package posts
import (
"log"
"appengine"
"appengine/datastore"
"github.com/GoogleCloudPlatform/go-endpoints/endpoints"
)
type Post struct {
UID string
Text string
Username string
Avatar string
Favorite bool
}
type Posts struct {
Posts []Post
}
type PostAPI struct{}
func init() {
_, err := endpoints.RegisterService(&PostAPI{}, "posts", "v1", "Posts API", true)
if err != nil {
log.Fatalf("Error: %v", err)
}
endpoints.HandleHTTP()
}
func (p *PostAPI) List(c appengine.Context) (*Posts, error) {
var posts []Post
_, err := datastore.NewQuery("Post").GetAll(c, &posts)
if err != nil {
return nil, err
}
return &Posts{posts}, nil
}
Getting the same error on linux machine, driving me crazy, I'm running go 1.5, goapp version is go version go1.4.2 (appengine-1.9.25) linux/amd64
Tried -u option when getting endpoints package, even tried deleting them manually, and still the same error. Running out of options...

and if I change func (p *PostAPI) List(c appengine.Context) (*Posts, error) to func (p *PostAPI) List(c context.Context) (*Posts, error) - the line datastore.NewQuery("Post").GetAll(c, &posts) throws:
/tmp/tmpiQTn0Tappengine-go-bin/posts.go:40: cannot use c (type context.Context) as type "appengine".Context in argument to "appengine/datastore".NewQuery("Post").GetAll:
context.Context does not implement "appengine".Context (missing Call method)
I am really not sure which Conext to use, the one from appengine package, the one from golang.org/x/net/context, I've even seen endpoints.Context which does not exist currently, endpoints documentation is really inconsistent regarding the Context usage.

Got it working by using google.golang.org/appengine/datastore with context.Context instead of appengine/datastore but not sure what is the difference ?
