Hi there,

i'm currently evaluating vaadin 23/24 for business applications. Somehow I am not satisfied with the grid / table. I just had a look at some RAP demos - the table behaves exactly as I would expect. It's also very fast ..

I'm just looking for some information on RAP and alternatives ...

* Is some consulting available (eclipsesource muc) ?
* Are there any modern themes available out of the box?
* Is RAP generally a good choice in conjunction with spring 5 and java17 ?
* Is it still true that RAP code is very similar to RCP code?

Any hint appreciated .. just wondering what stack could be a suitable choice to migrate business desktop apps.

Cheers,
Daniel

Ps: Anyone heard of captain casa business ui toolkit?

Hi Daniel,

straight to your questions:

1. EclipseSource provides both consulting and development support. See [1] for more details.
2. RAP framework provides two additional themes - business and fancy. You can check them in our Workbench demo. Creating your own theme is also easy with RAP.
3. RAP framework is working fine with Java 17. I can't comment anything on Spring 5.
4. Yes. RAP is still using the Eclipse RCP codding model, but also provides additional features and components for a modern web application like file upload, scripting, etc.

Hi Ivan,

thanks for this fast reply. I saw that you are senior developer with a long track record at EclipseSource. That is very good to know. Obviously you might be a support contact : )

I will push things forward regarding our project. I m very impressed bei the RWT. Just got an app up and running in less thant 30 mins ..

Cheers for your comments,
Daniel

Hi Daniel,

just fyi, since you are mentioning Spring, I'm using RWT as the UI toolkit in a Spring Boot 2.7 application (Java 17) and it's working like a charm (deployed on Azure). See [1] for details. However, I'm not using the RCP coding model (workbench, osgi, etc), so it's probably not a path for migrating existing RCP applications.

At the moment it's not possible to use it on Spring Boot 3.x because it's still using the Javax Servlet API. When Eclipse (and therefore RAP) move to the Jakarta EE API, this will also be fixed. See [2].

Cheers,
Ben

Hi Benjamin,

your comment is very helpful, cheers for that! Basically, the point you address is exactly what i am concerned about. I am also just interested in RWT as a UI Toolkit. We generate Java-Code out of logical models. RWT would be a charming solution to bring our apps into the web.

However, the javax servlet API moves in the jakarta namespaces and tomcat 10 onwards depends on the jakarta namespace. How will things be handled with RWT? Both APIs will be supported? What is generally the strategy behind RWT? Update to the latest tec standards and deprecated (eg. the javax servlet) older standards?

I m also wondering, how many people are behing RWT. Can it be seen as supported (long term) technology?

Cheers,
Dan

According to the following discussion, RWT will also move to Jakarta EE 9+ when Eclipse moves to the new API, but there is no guarantee yet: https://github.com/eclipse-rap/org.eclipse.rap/issues/108

Until this move, one will be stuck with the Javax API and the dependencies that use it, too.

As for the general RAP/RWT vision, you can find some statements about it in this forum, or let the devs respond on that.

Cheers,
Ben
