What IDE are using to compile your code?

 

by: autoknowledgePosted on 2008-02-29 at 10:12:13ID: 21015901

We're using Eclipse IDE.

When u created the java project did u add the jar file of the gwtext.jar?

 

by: contactkarthiPosted on 2008-02-29 at 11:47:46ID: 21016854

look at this tutorial with screenshots on how to eclipse with get-ext
http://www.gwt-ext.com/wiki/index.php/Using_Eclipse

 

by: FekratPosted on 2008-02-29 at 11:48:30ID: 21016860

Just in case u didn't go to the following link and download the jar file:
http://www.gwt-ext.com/builds/gwt-ext/29-feb-2008/gwtext.jar

Then right click your project in the left pane and click on properties then go to "java build path" then choose the libraries tab then click on "Add external Jars" then navigate to there and click open and it should work then.

Thanka experts!
I visited the link you guys have mentioned and i am happy that i can run my first example of gwt-ext library given there at my local environment.
After running it sucessfully i tried with other examples available at this url http://www.gwt-ext.com/dev/.
Steps i followed
Copied the source code of one widgets from there and pasted in my HelloWorld.java file. (This java file is that through which I could run my first gwt-ext example)
And i am getting this error when i am launching the application in hosted mode.

Error is :
[ERROR] Unable to load module entry point class com.mycompany.mypackage.client.HelloWorld (see associated exception for details)
com.google.gwt.dev.shell.HostedModeException: invokeNativeHandle(@com.gwtext.client.widgets.Panel::create(Lcom/google/gwt/core/client/JavaScriptObject;)): JavaScript undefined, expected com.google.gwt.core.client.JavaScriptObject
      at com.google.gwt.dev.shell.JsValueGlue.get(JsValueGlue.java:101)
      at com.google.gwt.dev.shell.ModuleSpace.invokeNativeHandle(ModuleSpace.java:226)
      at com.google.gwt.dev.shell.JavaScriptHost.invokeNativeHandle(JavaScriptHost.java:89)
      at com.gwtext.client.widgets.Panel.create(Panel.java:83)

      at com.google.gwt.user.client.ui.ComplexPanel.add(ComplexPanel.java:82)

      at com.google.gwt.dev.shell.ModuleSpace.onLoad(ModuleSpace.java:342)
      at com.google.gwt.dev.shell.BrowserWidget.attachModuleSpace(BrowserWidget.java:326)

Please confirm me the steps how could i use any available widgets at my environment. Since what are widgets available online of all we have access of java source. If i want to run at my environment how could i do that.

Have you added the location to gwtext.jar to your Eclipse project's classpath
- AND  -
the commandline files to compile your project (outside the scope of Eclipse)?

In windows, these 2 commandline files would be something like:
HelloWorld-compile.cmd, HelloWorld-shell.cmd
