I am currently trying to enable remote inspector for a OpenJFX web view component in order to be able to debug javascript code interactions with the Java part of the application. This is why I cannot debug the web part in a standalone browser.
There appears to be no detailed documentation related to remote inspector besides a few fixed scenarios which have pre-configured solutions available. Based on reverse-engineering and other research, I was able to piece together the following:
- I have obtained an instance of
Debuggerinterface out of the OpenJFXWebEngineinstance; - I have created a simple TCP server which communicates with the WebKit browser using its protocol (eg. messages like
"SetupInspectorClient","GetTargetList","SendMessageToBackend", etc.). This is enough to make the remote WebKit browser recognize my view when opening theinspector://localhost:<port>URI; - When attempting to connect to a particular view, the majority of the communication is handled by the
"SendMessageToBackend"and"SendMessageToFrontend"messages forwarded by my code between remote WebKit browser and theDebuggerinstance. However, based on communication traces the only response that the remote browser receives to its requests is a "'Target' domain was not found" and "'Browser' domain was not found" errors.
I presume the above problem may be caused by either incompatible webkit versions between OpenJFX and my remote browser - although I am using WebKit 613.1 on both ends. Other possibility is that the OpenJFX uses some sort of stripped-down WebKit which does not support the inspector commands at all. However, I don't know enough about WebKit to be able to find it out on my own.
Is it possible to get remote inspector working in OpenJFX 17, and if yes, then how?
