Exception sending context initialized event to listener instance of class [com.vaadin.flow.spring.VaadinServletContextInitializer$CompositeServletContextListener]
Description of the bug
I have migrated my vaadin 23 application to 24. And got this ERROR on startup Exception sending context initialized event to listener instance of class [com.vaadin.flow.spring.VaadinServletContextInitializer$CompositeServletContextListener]. java.lang.NoClassDefFoundError: com/vaadin/flow/server/PageConfigurator
Expected behavior
I have no idea which class is using it.
Minimal reproducible example
Migrate Vaadin 23 to Vaadin 24. Vaadin version: 23 -> 24 Spring Boot version: 2.7 -> 3.0
Versions
- Vaadin / Flow version: 24.3.1
- Java version: 17
- Spring boot version: 3.0.0
Sounds like a version mismatch and you still have some old dependencies in your tree.

Do you mean version of third party libraries too?
Anything that could contain Vaadin flow dependencies
Yeah i have commented one library (that i was not using) and my application has started. But i got another errors frontend cannot build. Because earlier i deleted some generated files node_modules,package.json, package-lock.json. How can i clean and rebuild everything?
Vaadin recreates those files if they are missing. You can try to execute vaadin:dance with Maven.
There is also https://vaadin.com/docs/latest/upgrading to follow

Thank you very much, my application is working, but i have another questions.
- Now application is taking too much time to launch, what might be a reason? Before in vaadin 23, there was no such problem.
- I dont see a message like it was shown before in Vaadin 23.
------------------ Starting Frontend compilation. ------------------ <
But i still can open a webpages and i see that it is starting in Development mode, should i need to make some configurations?
You should read the patch notes of the releases in between your old and the new version. A lot of things changed / improved.
Only the first start should be slow while npm is executed to load dependencies.

i have started several times already, it takes 35 seconds to launch all the time compared to 11 seconds in Vaadin 23.
But what about a message, why it is not shown in logs?

@lazizbektulanov Could you please post the full logs?
If you start the application with maven from the command line, please add these arguments to the command: -Dorg.slf4j.simpleLogger.showDateTime -Dorg.slf4j.simpleLogger.dateTimeFormat=HH:mm:ss.SSS

@lazizbektulanov your log snippet shows that the app is starting within 12 secs and also it says:
Checking if a development mode bundle build is needed
A development mode bundle build is not needed
which means that your application doesn't need a frontend compilation and it may use the pre-compiled bundle (which should be faster, see https://vaadin.com/docs/latest/configuration/development-mode#precompiled-bundle). That's why you don't see the Starting Frontend compilation message, as it only shown when frontend installation, compilation and dev server startup happens.
btw i'm also getting this warning:
Do you use localhost to open your app ? Vaadin blocks debug window connections for non-localhost connections, so that if you share the application with anyone else, the connection is refused by default.
If so, please set up the config parameter vaadin.devmode.hostsAllowed as described here
https://github.com/vaadin/flow/issues/18351#issuecomment-1870018809.
This unfortunately misses a documentation currently.
@lazizbektulanov your log snippet shows that the app is starting within 12 secs
Startup time was 36 secs, it is speeded up after adding this to my application.properties:
vaadin.whitelisted-packages=com.flowingcode
Is it ok with adding this config?
This parameter allows you to limit the class scanning made by Vaadin to a given packages, improving the application startup and reload time, and it's fine to use this parameter. The segments in the package name should be separated by slash /, not by dot ., see the docs.
So original issue with thrown exception is solved, but there is a startup time question:
Now application is taking too much time to launch, what might be a reason?
Could you please provide a server log before adding vaadin.whitelisted-packages=com.flowingcode with the DEBUG level enabled, so we can analyse what takes a bigger time now for V24 comparing to what you had for V23?
Of course

This might be wrong, but my very random though is that previously with V23 you had 11 seconds for spring app to start, but there was a background process for npm installation, frontend compilation and Vite dev server startup time that takes much longer than 11 sec, so in practice the total time was minutes before you can access the app in browser. Now with V24 you can avoid frontend compilation, so the total time is 35 secs, but this is less than with "hotdeploy" mode that was a default in V23.
