Upgrading GWT from 1.7 to 2.0 - gwt

I am trying to upgrade GWT 1.7.0 to 2.0.0 but I get the following error.
Errors in 'jar:file:/C:/src/lib/gxt.jar!/com/extjs/gxt/ui/client/widget/Component.java'
As per the below link I did everything as shown.
How to upgrade GWT from 1.7 to 2.0
I am guessing there is no need to upgrade GXT. The GXT version I'm using is 1.2.5
Any ideas would be highly appreciated.

Definitely a compatibility problem with GXT and GWT. According to the GXT website you need to upgrade your gxt version to at least version 2.0.2. Try downloading GXT 2.2.5 (non-commercial version) and try it out with GWT 2.0 or even 2.4.

I install the Google Plugin 4.4 in my eclipse LUNA (version 4.40) , but I don't know it and which GWT Designer plug-in matching

I choosed this version of google Plugin: https://dl.google.com/eclipse/plugin/4.4
but I should choose which version of GWT Designer?
GWT Designer isn't maintained and won't work with latest version of GWT. You'd better not spend time trying to install/configure it.

GWT 2.4.0 with Google Web Toolkit Plugin 3.8.0.v201410302155-rev-r42

I have a customer requirement of GWT 2.4.0 due to a Java 5 limitation. Up until this latest Google Web Toolkit Plugin update I have been able to successfully use the plugin with GWT 2.4.0. I am seeing an error regarding a missing gwt-codeserver.jar and the GWT plugin says that GWT is not installed. Is there anything I can do as a workaround for using GWT 2.4.0 and the latest Eclipse/GWT plugin?
I had the same issue. I have downloaded the newest version of GWT just to copy the gwt-codeserver.jar in my SDK folder. So I didn't have the error anymore.
Also, in my debug/run configuration, I have removed the argument "-nosuperDevMode".
I was experiencing the same problem and like Gildas, I copied the gwt-codeserver.jar from GWT 2.6.0 into the 2.4.0 folder.
The next thing I had to do to get it to work was, when adding the 2.4 SDK, I had to point to the gwt2.4.0 folder as opposed to the parent "com.google.gwt.eclipse.sdkbundle_2.4.0.v201208080121-rel-r42" folder. Clean and build, good to go...with this problem, at least.

Possible to do GWT 2.2 Maintenance in Eclipse Kepler?

I have the task to do some work on our GWT 2.2 code base with
the GWT Config, etc, used, is long gone. And I must use Eclipse Kepler.
Does current GWT provide backward compatability that far?
Any thoughts?
The version of the Eclipse plugin is independent of the version of the SDK you use in your project. You can use the newest plugin with GWT projects that needs older versions of the SDK.
You have to set this up in the project properties.

WiQuery version for Wicket 1.5.10

Which WiQuery version is proper for Wicket 1.5.10? Is it WiQuery 1.5.8 (the last from 1.5.x branch) or can be used the new version 6.6.0?
As the WiQuery project page says, version 6.x has been compiled against Wicket 6.x, so you won't be able to use it with Wicket 1.5.
The latest WiQuery version compiled against 1.5 and available in Maven central is 1.5.8.

Upgrading GWT to latest version

2 years back We have developed an application using GWT 1.4.6 and GWT-Ext 2.0.3 frameworks.
Now our management is thinking of upgrading these two frameworks.
But the Gwt-Ext website states that the development of Gwt-Ext has been superseded by smart GWT.
I just want to ask that if we update/upgrade from GWT 1.4.6 to GWT 2.2, whether Gwt-Ext 2.0.3 will work or not ?
if anyone have any experience in this please give me some inputs to move forward.
We had the same situation, we wanted to upgrade GWT 1.4 to 2.1.0 and we had GWT-Ext 2.0.3 which was the end of that project but there was 2.0.5 available though with minor changes.
The transition was not smooth but it was not also worst. We tried to attach new plug-in to our source in Eclipse and it complained about:
Removal of some unnecessary inherts in x.gwt.xml (main entry file)
The public folder was replaced with the new Ext 2.0.5 files
We were using ftr-gwt libarary where there were some mismatch with the method signatures and return types. But were simple.
And I don't remember running into any serious problems.
I believe it was in GWT 2.1 that Google updated their built in interface widgets dramatically. Because of this, my experience has been that the various widget libraries (GXT, SmartGWT) have had to update their libraries to support gwt 2.2. So my guess for your question is that GWT-EXT 2.0.3 probably will not work with GWT 2.2 or the newer 2.3.
