debug mode from eclipse

[Jim]

Hi.  I'm new to GWT and came across your project.  You've got some really great stuff here. 

I've been struggling a little to figure out how to build and run your project from source using eclipse indigo.  I imported the base project as a maven project and was able to build it successfully.  Now I'm trying to load the samples in development mode but I get runtime errors in chrome each time I tried to run them. 

Is it possible to load the samples, make changes and test it in the development environment?

Hi,

I have migrated to Eclipse Indigo so yes you should be able to build the source and samples from the trunk:

-> http://code.google.com/p/gwt-cx/source/browse/#svn%2Ftrunk

You will need to be more specific re the issues you are experiencing.

These new posts may help:

BTW, I am working on an updated download (.zip) at the moment.

Thanks.  I'm probably just missing a step somewhere.

Again, the only things I have installed are the maven command line tools, (so I could add the missing dependencies using mvn install) and eclipse with plugins.

 I've imported using:

File->Import->Maven->Import Existing Maven Project

then I select the gwtcx folder

If I right click on the project I can select Run As->Maven Build....

Then under Goals I type:  clean install

After that I import one of the sample apps:

File->Import->Maven->Import Existing Maven Project

then I select the gwtcx\gwtcx-samples\gwtcx-samples-gwt\gwtcx-samples-gwt-basic folder

If I right click on the project I can select Run As->Maven Build....

Then under Goals I type:  gwt:run

After that the browser throws up the following error:

onModuleLoad() threw an exception

Exception while loading module com.gwtcx.sample.basic.client.entrypoint.Basic. See Development Mode for details.

Hi,

Ok, first things first, your environment have you set it up as per this post:

->  http://kiahu.com/tutorial/working-with-gwt-maven-and-the-google-plugin-for-eclipse/

If you have you can test your environment by following this post:

-> http://kiahu.com/tutorial/generate-a-skeleton-project-using-gwt-and-maven/

If your environment is good to go then you can check out the source and then execute the following commands (in the root folder gwtcx) from your IDE or the command line:

mvn gwt:clean
mvn clean package
mvn gwt:run

That will build gwt-cx and the gwt-cx samples.

I am in the middle of refactoring the samples (and a few other things) so your best bet is to try out the Ext GWT sample:

-> http://code.google.com/p/gwt-cx/source/browse/#svn%2Ftrunk%2Fgwtcx%2Fgwtcx-samples%2Fgwtcx-samples-extgwt%2Fgwtcx-samples-extgwt-serendipity%253Fstate%253Dclosed

This sample use GAE so you need to launch the dev app sever (from the target directory e.g. C:\tools\IDEs\helios\workspace\kiahu\gwtcx\gwtcx-samples\gwtcx-samples-extgwt\gwtcx-samples-extgwt-serendipity\target)

For example:

C:\tools\gwt-appengine-java-sdk-1.6.3.1\bin\dev_appserver.cmd gwtcx-samples-extgwt-serendipity-1.0.0-dp1

and then navigate to the host page:

http://localhost:8080/index.html

When your finished just Control-C in the terminal session (command prompt).

BTW, you also need -> https://developers.google.com/appengine/downloads#Google_App_Engine_SDK_for_Java

Let me know how you go.

N.B. I am also working on a stand alone sample that is to be discussed in this:

-> http://kiahu.com/tutorial/getting-started-with-kiahu-cx/

 and subsequent posts.

Cheers
Rob

Thanks for your help Rob it seems I'm a least a little closer.

It looks like my environment is set up ok.  The skeleton project ran ok.  The "mvn gwt:clean" command seems to execute correctly, as does the "mvn clean package" command

The "mvn gwt:run" command doesn't seem to work though:

Hi,

Ah, my bad:

mvn gwt:clean
mvn clean package

Executed in the root folder "gwtcx" (or right-click on the pom.xml in the IDE) will build gwt-cx and the gwt-cx samples.

To run the Ext GWT Serendipity sample you need to launch the GAE dev app sever (e.g from the target directory e.g. C:\tools\IDEs\helios\workspace

Have you installed the m2e plugin as per this post -> http://kiahu.com/tutorial/working-with-gwt-maven-and-the-google-plugin-for-eclipse/

Let me know how you go.

Thanks for the help Rob.  This did the trick.

Jim

I think you are using a newer version of the App Engine toolkit.

As per the error -> WEB-INF/appengine-web.xml
Jun 27, 2012 2:32:49 AM com.google.apphosting.utils.config.AppEngineWebXmlReader
 readAppEngineWebXml

Can you try adding a threadsafe element to the appengine-web.xml file

->

<threadsafe>true</threadsafe>

->

Cheers

Rob
