Happen error with Serializer in native app about activej HOT 2 CLOSED

Hi, @anboo44

You have to properly set up the native-image tool by specifying all reflection access points. You also need to configure your Modal class to be accessible as a resource. Since ActiveJ generates new classes you also need to specify a configuration for predefined classes.

This configuration goes out of the scope of the ActiveJ project and is more of a GraalVM/native-image issue.
I was able to run your example by creating a fat jar and then running a native-image agent with experimental-class-define-support option on it and then using generated configuration files to generate a binary executable.

This works for known classes but unfortunately would not work if your application generates new classes dynamically, since native-image only supports generating predefined classes.

@eduard-vasinskyi Thank you so much. The my sample code worked

I note my steps if anyone needs:

• Build jar file
• Run command: java -agentlib:native-image-agent=config-output-dir=config,experimental-class-define-support -jar file_name.jar => it will create new folder with name: config
• In resources, create new folder with name: META-INF and then copy above config folder to META-INF. After that, rename config to native-image
• Build jar file again
• Run command: native-image -jar file_name.jar
  => DONE

This works for known classes but unfortunately would not work if your application generates new classes dynamically, since native-image only supports generating predefined classes.
I understand about this. So sad T_T
