JavaFX NoClassDefFoundError zap plugin Browser View

Question

I want to use the Browser View Plugin for Owasp Zap, but getting the following error:

19529 [ZAP-BootstrapGUI] WARN  org.zaproxy.zap.extension.browserView.ExtensionHttpPanelBrowserView - Unable to use JavaFX:
java.lang.NoClassDefFoundError: javafx/embed/swing/JFXPanel

I have openjfx , openjfx-source , libopenjfx-jni , libopenjfx-java , libcontrolsfx-java and libeasybind-java installed. I also have tried it with openjdk8 and 14. My system is Ubuntu 20.10, but I also get the same error when I use the machines from tryhackme .

Thanks for your help

Answer 1

In order yo use the Browser view add-on you have to install JavaFX.

sudo apt install openjfx for Ubuntu.

You may also need to set the jfx path ( https://openjfx.io/openjfx-docs/#install-javafx ): export PATH_TO_FX=path/to/javafx/lib

Per: https://github.com/zaproxy/zaproxy/issues/6339#issuecomment-758173453 , you may also need to start ZAP as follows (or edit the shell script to do the same): $ java --module-path /usr/share/openjfx/lib/ --add-modules javafx.swing,javafx.web zap.jar
