GWT problem, GWT.create(SomeClass.class) throw exception
Solution 1
GWT 2.3 requires javax.validation jar: http://mvnrepository.com/artifact/javax.validation/validation-api/1.0.0.GA
Download it and add it to your project lib folder.
Solution 2
today I had exactly the same problem. here is the solution:
the files: validation-api-1.0.0.GA-sources.jar and validation-api-1.0.0.GA.jar which can be found in the downloadable gwt sdk should be in your classpath when compiling or executing dev-mode. the sources jar is critical, therefore Peter's solution did not work.
Solution 3
I had similar problem which was caused by typo
Wrong (throws Cast Exception):
private final UserService userRpcService = GWT.create(UserService.class);
Correct (added ...Async):
private final UserServiceAsync userRpcService = GWT.create(UserService.class);
Solution 4
as the exception already stated: did you forget to inherit a required module?
For example, is the "MyUser" available?
Solution 5
After reading this question and looking at the answers, here's the solution:
If you updated your libraries manually by copying the new gwt files : (which a lot of us did)
copy your validation-api-1.0.0.GA.jar and validation-api-1.0.0.GA-sources.jar into the gwt-dependencies directory.
remove all VAADIN_DOWNLOAD variables from your classpath.
Add the following variables to the project's build path with the following entries: gwt-dev.jar, gwt-user.jar,validation-api-1.0.0.GA.jar AND validation-api-1.0.0.GA-sources.jar.
Compile widgetset
- Enjoy life
If you haven't updated your libraries manually by copying the new gwt files :
- Update your plug-in
- Make sure the files validation-api-1.0.0.GA.jar AND validation-api-1.0.0.GA-sources.jar are present in the gwt-dependencies directory
- Modify the existing variables and add the 2 new variable entries (validation-api-1.0.0.GA.jar AND validation-api-1.0.0.GA-sources.jar) into your classpath.
- Compile widgetset
- Enjoy life

and a few explanation
Webcharge is my entry point for the project, as you can see in the stacktrace the exception is thrown (WebchargeService.java:21) where at that line i have private static WebchargeServiceAsync ourInstance = GWT.create(WebchargeService.class);
WebchargeService
@RemoteServiceRelativePath(value = "WebchargeService") public interface WebchargeService extends RemoteService { String getMessage(MyUser user); List<MyUser> getUserList(); List<MyUser> updateUser(MyUser user) throws Exception; List<MyUser> selectByName(String name); String getMessage(String msg); public static class App { private static WebchargeServiceAsync ourInstance = GWT.create(WebchargeService.class); public static synchronized WebchargeServiceAsync getInstance() { return ourInstance; } } }
and the code for WebchargeServiceAsync
public interface WebchargeServiceAsync { void getMessage(String msg, AsyncCallback<String> async); void getMessage(MyUser user, AsyncCallback<String> async); void getUserList(AsyncCallback<List<MyUser>> async); void updateUser(MyUser user, AsyncCallback<List<MyUser>> async); void selectByName(String name, AsyncCallback<List<MyUser>> async); }
Any help is welcome :)
Thanks.

brakebg about 13 yearsWhat do you mean under "available" ? yes i have a bean class MyUser. But i don't understand this message - > did you forget to inherit a required module?
-
TxANG about 13 yearsdid you forget to inherit a required module phrase is always related to your gwt.xml file, asking if you have forgotten to <inherits> any library, jar or external module. In other cases, when you use some unsupported java classes on client side, you will get this error too.
-
brakebg about 13 yearsI got the same exception even when i import a existing sample project. For example i tried this one - hg clone gwt-dispatch-example.googlecode.com/hg gwt-dispatch-example but again exception is thrown executing private final MyGinjector injector = GWT.create(MyGinjector.class);
-
brakebg about 13 yearsJust something is generally wrong with my env. Please if you have any suggestions let me know, i m desperate :-)

Peter Knego about 13 yearsTry using this sample project with GWT version before 2.2.
-
Peter Knego about 13 yearsYou need gin-1.5-post-gwt-2.2.jar with GWT 2.2 and 2.3
-
Peter Knego about 13 yearsThis example project uses Gin 1.0. It won't work under GWT 2.2 or 2.3.

MrHutnik over 5 yearsdoes it have to be this exact version though?
