Re: GWT+Gmaps Unable to load Google Map [no error]
Hello G,
I looked over your files and didn't see anything obvious.
Unfortunately, the maps documents haven't been updated for GWT 1.6 or
the Google Plugin. Here are some suggestions:
1) Did you try using hosted mode and setting a break point in your
EntryPoint class?
2) You also could try running in web mode under firebug and see that
the maps API URL (http://maps.google.com/maps) is being successfully
loaded.

I am fairly new to GWT + Google Maps toolkit.
I am using eclipse pulgin on windows and was able to successfully
compile and deploy ExampleWebApp on Google AppEngine Tomcat.
I am now struggling to get the SimpleMaps example working. I have
1.6.4 plugin gwt-maps-1.0.4. I am not getting any compile time or
runtime error but the map itself is not showing (I ran ethereal and
looks like there is no request made). I checked my proxy settings in
the hosted browser and I can access google page without any problem.
(I went through most of the questions on the forums but it didnt seem
to help in my case).
I didnt run applicationcreator packageCreator because:
#1 I just couldn't find those scripts. (Can you please point me to it,
it was not there in the \gwt-windows-1.6.4 dir)
# 2 I read that GWT 1.6 onwards, I dont have to run those to create
GWT eclipse project.
I am enclosing the files I used; hope someone can point me something
obvious. I did include the gwt_maps.jar as external jars and as I
mentioned I do not get any error whatsoever. I even tried deploying to
google and tomcat and firefox browser, the map just doesn't come up.
All I see is blank...

Re: GWT+Gmaps Unable to load Google Map [no error]
I tried changing the following line in SimpleMap.java and to my surprise, and it compiled. RootPanel.get(mapsSSSTutorial).add(map); I am using the GWT Compile Project button on eclipse toolbar. Output of compilation: Compiling module com.google.gwt.maps.GoogleMaps.SimpleMaps Compiling 5 permutations Permutation compile succeeded Linking into war Link succeeded Compilation succeeded -- 10.968s When I looked at the firebug, I dont see the any maps API URL embedded in the HTML. Putting breakpoint in the Entryoint class doesn't work either. Looks like that class doesn't even get called. Which makes me think, I may be missing something real obvious.

Re: GWT+Gmaps Unable to load Google Map [no error]
The change you made compiles because the lookup of the argument to RootPanel.get() is done at runtime. If you are new to GWT, have you run through the general GWT tutorial? It shows how to use the Java Debugger with Hosted mode.

Re: GWT+Gmaps Unable to load Google Map [no error]
Eric, I will go through the GWT debugging tutorial. thanks But what I dont understand is I dont get any errors at all. What would be nice is to have an example of Googlemaps + GWT (version 1.6.4)...hope that can be published shortly... I want to write a fairly complex system using this and I am stuck at the very basic...
