Hello @mangel.gonzalez

The cuba.web.productionMode app property enables to manage whether Vaadin developer console can be opened or not.

All unexpected errors are handled by DefaultExceptionHandler. So I suggest you to implement your own exception handler and, for example, just log exceptions. Please read our documentation for more details: Client-Level Exception Handlers.

Hello Danii,

In the follow example I get to catch the exception “SQLException”;

@Component("sample_AdqExceptionHandler")
public class AdqExceptionHandler extends AbstractGenericExceptionHandler{

    private Logger log = LoggerFactory.getLogger(AdqExceptionHandler.class);

    public AdqExceptionHandler() {
        super(JPQLException.class.getName());
    }

    @Override
    protected void doHandle(String className, String message, @Nullable Throwable throwable, WindowManager windowManager) {
        log.error("ERROR:  TEST DefaultExceptionHandler");
    }

}

I´ve tried to catch the exceptions; EclipseLinkException, RuntimeException and Exception in the same way but it´s not working!!!. . . . . . do you know how could I do it?

Thank a lot!

#7

Could you share a code that you use to handle these exceptions?

#8

Yes of course!! . . . . Thank a lot!!

I use the follow example to handle the exception “EclipseLinkException” . . … . but it´s not working

@Component("sample_AdqExceptionHandlerEclipseLink")
public class AdqExceptionHandlerEclipseLink extends AbstractGenericExceptionHandler{

    private Logger log = LoggerFactory.getLogger(AdqExceptionHandlerEclipseLink.class);

    public AdqExceptionHandlerEclipseLink() {
        super(EclipseLinkException.class.getName());
    }

    @Override
    protected void doHandle(String className, String message, @Nullable Throwable throwable, WindowManager windowManager) {

        log.error("ERROR:  TEST AdqExceptionHandlerEclipseLink");

        if (throwable != null)
            windowManager.showExceptionDialog(throwable, "Exception is thrown", message);
    }

}

I use the follow example to handle the exception “RuntimeException” . . … . but it´s not working

@Component("sample_AdqExceptionHandleRuntime")
public class AdqExceptionHandleRuntime extends AbstractGenericExceptionHandler{

    private Logger log = LoggerFactory.getLogger(AdqExceptionHandleRuntime.class);

    public AdqExceptionHandleRuntime() {
        super(RuntimeException.class.getName());
    }

    @Override
    protected void doHandle(String className, String message, @Nullable Throwable throwable, WindowManager windowManager) {

        log.error("ERROR:  TEST AdqExceptionHandleRuntime");

        if (throwable != null)
            windowManager.showExceptionDialog(throwable, "Exception is thrown", message);
    }

}

I use the follow example to handle the exception “Exception”. . … . but it´s not working

@Component("sample_AdqExceptionHandleException")
public class AdqExceptionHandleException extends AbstractGenericExceptionHandler{

    private Logger log = LoggerFactory.getLogger(AdqExceptionHandleException.class);

    public AdqExceptionHandleException() {
        super(Exception.class.getName());
    }

    @Override
    protected void doHandle(String className, String message, @Nullable Throwable throwable, WindowManager windowManager) {

        log.error("ERROR:  TEST AdqExceptionHandleException");

        if (throwable != null)
            windowManager.showExceptionDialog(throwable, "Exception is thrown", message);

    }

}

Please note that if you want to use the same class for few exception types you have to pass their class names into super like this:

public AdqExceptionHandlerEclipseLink() {
    super(EclipseLinkException.class.getName(),
            RuntimeException.class.getName(),
            Exception.class.getName());
}

Where is your exception handler located?

#10

Hi Daniil,

Thanks for your answer.

The examples I posted above are independent. I don’t have any problems catching multiple exceptions, but catching specific exceptions.

For example, I can catch JPQLException just fine with AdqExceptionHandleException. But EclipseLinkException, RuntimeException and Exception are all catched by CUBA’s DefaultExceptionHandler even after changing super(JPQLException.class.getName()); for super(Exception.class.getName()); in my custom exception handling class.

All my exception handling classes are located in the web module at com.company.exceptions.AdqExceptionHandleException.

Best regards.

In another word, I would like to use AdqExceptionHandler to catch whatever exception not only JPQLException… . . thanks a lot!!!

@Component("sample_AdqExceptionHandler")
public class AdqExceptionHandler extends AbstractGenericExceptionHandler{

    private Logger log = LoggerFactory.getLogger(AdqExceptionHandler.class);

    public AdqExceptionHandler() {
      super(JPQLException.class.getName());
    }

    @Override
    protected void doHandle(String className, String message, @Nullable Throwable throwable, WindowManager windowManager) {
        log.error("ERROR:  TEST DefaultExceptionHandler");

        if (throwable != null)
            windowManager.showExceptionDialog(throwable, "Exception is thrown", "My custom exception");
    }
}

I’ve prepared an example for you. Please look for CustomExceptionHandler and exceptions thrown from Screen

ex-handlers.zip (71.3 KB)

Hope it’ll help you
