GWT Google Maps Eclipse configuration

[Luser_k]

Please can someone help me out there?

I have eclipse and created a GWT project and imported the project into
my workspace of eclipse.
I add the external jars like

1. gwt-google-apis.jar
2. gwt-user.jar
3. gwt-dev-windows.jar

Although I add the jars, I get a exception that the apis can´t found
and that a inheritance didn´t work !?

I coded this in my .java:



package com.google.gwt.client;

import com.google.gwt.core.client.EntryPoint;
import com.google.gwt.maps.client.InfoWindowContent;
import com.google.gwt.maps.client.MapWidget;
import com.google.gwt.maps.client.control.LargeMapControl;
import com.google.gwt.maps.client.geom.LatLng;
import com.google.gwt.user.client.ui.RootPanel;

public class rmaps implements EntryPoint {

public MapWidget map;

public void onModuleLoad() {

map = new MapWidget(new LatLng(39.509,-98.434),2);
map.setSize("500px","300px");
map.addControl(new LargeMapControl());
map.getInfoWindow().open(map.getCenter(),new
InfoWindowContent("Hallo Welt"));

RootPanel.get("slot2").add(map);
}
}





Thats the error message:

[TRACE] The development shell servlet received a request for
'rmaps.html' in module 'com.google.gwt.rmaps'
[TRACE] Loading module 'com.google.gwt.rmaps'
[TRACE] Loading inherited module 'com.google.gwt.maps.GoogleMaps'
[ERROR] Unable to find 'com/google/gwt/maps/GoogleMaps.gwt.xml' on
your classpath; could be a typo, or maybe you forgot to include a
classpath entry for source?
[ERROR] Line 5: Unexpected exception while processing element
'inherits'
[ERROR] Failure while parsing XML




Thats my module:

<module>

<!-- Inherit the core Web Toolkit stuff. -->
<inherits name='com.google.gwt.user.User'/>
<inherits name='com.google.gwt.maps.GoogleMaps' />
<!-- Specify the app entry point class. -->
<entry-point class='com.google.gwt.client.rmaps'/>

</module>
================================================


How can I inherit the gwt-google api, "GoogleMaps.gwt.xml" ???
I mean, when I inherit it still doesnt work. I mean how can the
module know where that xml file locates? How do I eclipse say,
where that file is?

How can I put that file into my Classpath?

Can someone explain me very detailled how i can inherit and I mean
not just to put the inherit tag in the module.

Please help me!!!!

Have you added the library in Build Path? To do it follow these steps:

1. Right click on the project name in the Eclipse --> Build Path -->
Configure Build Path
2. Click on the button 'Add External JARs...'
3. Select the 'gwt-google-apis.jar' file (where you have downloaded
it)
4. Click on 'OK' button

And that's all!

Let me know if this works.

Regards.

Hi,

thanks for your reply.

I deleted my gwt-project and created a whole new project with the
applicationCreator and projectCreator.

- I added the external jar like you said with the build-path.
- I coded following code:

package com.reko.client;

import com.google.gwt.core.client.EntryPoint;
import com.google.gwt.maps.client.InfoWindowContent;
import com.google.gwt.maps.client.MapWidget;
import com.google.gwt.maps.client.control.LargeMapControl;
import com.google.gwt.maps.client.geom.LatLng;
import com.google.gwt.user.client.ui.RootPanel;

public class MyGmapsApplication implements EntryPoint {


private MapWidget map;

public void onModuleLoad() {

map = new MapWidget(new LatLng(39.509,-98.434),2);

map.setSize("500px","500px");
map.addControl(new LargeMapControl());
map.getInfoWindow().open(map.getCenter(),new
InfoWindowContent("World's Largest Ball of Twine"));

RootPanel.get("slot1").add(map);
}
}

- When I compile and shell the code, I get this Exception from the
shell :

- The import does not work, although I added the jar and the IDE
accepted it.
Could you please, really please explain me how I can solve my
problem?

I wrote up a step-by-step procedure for how to configure eclipse on
the gwt-google-api wiki page that others have found helpful. Have you
seen this yet?

http://code.google.com/p/gwt-google-apis/wiki/GettingStartedBasic

Also, I can tell by the name of the .jar file that you are using an
older version of the API. Try downloading the r290 milestone release:

http://code.google.com/p/gwt-google-apis/downloads/list?can=1&q=r290&colspec=Filename+Summary+Uploaded+Size+DownloadCount

Kick me if I don't update the GettingStartedBasic page to reflect the
new .jar file structure soon.
