JDK 17 and GIN about gwt HOT 16 CLOSED

The problem is that Gin doesn't support Jakarta, and is unmaintained, so will likely not get a new update. Someone at Google would need to initiate this, or at least support it.

There is no requirement to stop using javax packages and switch to jakarta when using Java 17.

from gwt.

Guice 7 moved to jakarta.inject, you need to use Guice 6 or earlier with GIN to stay on javax.inject.

I am using Guice 7 as noted in my steps to reproduce

from gwt.

…which is the problem. Downgrade to Guice 6 and it should work 🤞

from gwt.

Shouldn't I be using Jakarta since I'm upgrading to JDK 17?

from gwt.

That solved that, now
filterRegex(FILTER_STRING).through(AuthFilter.class); is giving

C:\SVNWorkspace\life-uiSpring\src\main\java\com\mutualofomaha\nbs\ui\utils\AppServletModule.java:63: error: no suitable method found for through(Class)

method FilterKeyBindingBuilder.through(Key<? extends Filter>) is not applicable

method FilterKeyBindingBuilder.through(Filter) is not applicable

Is there a library I missed?

from gwt.

Actually, I think that is due to more jakarta's that need to change

I am now running into this

Are any of these causing my issues?

from gwt.

@dgeiselmanMOO It is not clear to me what your current goal is? Do you simply want to upgrade to JDK 17 or are you also trying to move everything to Jakarta? Also is your GWT client code in the same project as your server side code?

The above errors you are seeing usually mean that calls to GWT.create(<some interface or abstract class>) failed. Either because there was no generator / rebind rule defined in a *.gwt.xml file or the generator threw an exception. Usually the log shows the root cause.

Generally you are not required to use Jakarta just to use Java 17. However more and more libraries/projects will use Jakarta in the future. Because you are using GIN, which only supports javax.inject, it would be wise to split your project into a GWT/UI project and a server project. Then both projects can evolve independently and the GWT/UI project can use GIN 2.1.2 + Guice 6.0.0 with javax.inject while the server might use Guice 7 and Jakarta.

from gwt.

Right now the goal is to figure out where the errors are occuring so I can fix them. I'm past the Javax/Jakarta issue and the errors I'm getting with the DOMImpl and CellBasedWidgetImpl are both in strict and when I compile without strict. I'll check for the GWT.create are there any others I need to hunt for?

This error for example is pure GWT internal. Basically DOM internally calls GWT.create(DOMImpl.classs) because some browsers behave differently with regard to DOM operations GWT uses. I think the root cause might be that your project uses user.agent values that GWT does not support anymore. The only valid values right now are safari (Safari / Chrome based browsers) and gecko1_8 (Firefox / IE 11).

So you should check:

• in your 3rd party GWT libraries check if they are nasty and provide their own com.google.gwt....DOM/DOMImpl implementation to override the one provided by GWT. That is almost always bad.
• Check if your app and 3rd party libraries use a user.agent property that is not supported anymore by GWT SDK. GWT 2.10 dropped support for ie8, ie9, ie10 values for user.agent.

from gwt.

Ok, so

<extend-property name="user.agent" values="ie8" />
<extend-property name="user.agent" values="gecko1_8" />
<extend-property name="user.agent" values="safari" />
<extend-property name="user.agent" values="ie9" fallback-value="ie8" />

Should only have Safari and Chrome and get rid of ie and gecko?

from gwt.

No, search for ie8, ie9, ie10 in your *.gwt.xml files and the ones of your 3rd party dependencies.

from gwt.

All I have now is safari, do I need gecko1_8?

from gwt.

If your application should support FireFox and IE 11 then you also need gecko1_8.

from gwt.

Ok, that took care of my issues. Thank you for the help
