Hi,

Currently efxclipse has dependency on javafx 2.2. I want to use 'ControlsFX' javafx library but it requires JavaFX- 8u20 version. Is it possible to use javafx 8.x with efxclipse application?

Secondly I am using jdk 8.20 and javafx rutime 'jfxrt.jar' is in the jre path, but if I remove javafx plugin dependency (org.eclipse.fx.javafx_2.2.0.x.jar) then why application don't find javafx classes?

Hi Mandar

I use efxclipse 1.0 with JDK 8u20, ControlsFX 8.20.7 and openjfx-dialogs 1.0.2, so yes, it is possible.
The version number of the plugin org.eclipse.fx.javafx 2.2.0 does not restrict the jdk you use.
You need this dependency in OSGi/Equinox applications so that the bundle classloader can find the JavaFX classes.

Have you tried it? What happend?

Greetings
Christoph

Hi Christoph

I am using Dialogs from ControlFx.
Code :
Action response = Dialogs.create().owner(scene.getWindow())
.title("Confirm Save")
.message("Do you want to save the changes?").showConfirm();
When above dialog is shown following error is thrown.

Caused by: java.lang.ClassNotFoundException: com.sun.javafx.scene.traversal.Algorithm cannot be found by org.controlsfx_8.20.7
at org.eclipse.osgi.internal.loader.BundleLoader.findClassInternal(BundleLoader.java:432)
at org.eclipse.osgi.internal.loader.BundleLoader.findClass(BundleLoader.java:345)
at org.eclipse.osgi.internal.loader.BundleLoader.findClass(BundleLoader.java:337)
at org.eclipse.osgi.internal.loader.ModuleClassLoader.loadClass(ModuleClassLoader.java:160)
at java.lang.ClassLoader.loadClass(ClassLoader.java:357)
----
Now com.sun.javafx.scene.traversal.Algorithm class is not available in plugin org.eclipse.fx.javafx 2.2.0 but is in JDK 8u20

org.eclipse.fx.javafx does export "com.sun.javafx.scene.traversal" - the
org.eclipse.fx.javafx-bundle is only a fake bundle. Make sure the JRE
you are launching is really the u20.

hmm.. it is strange, the same code works in plain JavaFx Application.
I am running both the apps from development environment . The java path shown in console is same - '/Library/Java/JavaVirtualMachines/jdk1.8.0_20.jdk/Contents/Home/bin/java'.

Hi Tom,

I am new to eclipse rcp. To integrate controlFx lib, I have created a plugin 'org.controlsfx' from controlFx jar file. Is this a right way to integrate third party libs ?

Did you add "org.eclipse.fx.javafx"
as a dependency to "org.controlsfx" in its MANIFEST.MF?

This is what our MANIFEST.MF for ControlsFX looks like:

Manifest-Version: 1.0
Bundle-ManifestVersion: 2
Bundle-Name: Controls FX
Bundle-SymbolicName: de.emsw.gosa.lib.controlsfx;singleton:=true
Bundle-Version: 8.0.7
Bundle-ClassPath: .,
 controlsfx-8.20.7.jar,
 openjfx-dialogs-1.0.2.jar
Export-Package: javafx.scene.control,
 org.controlsfx,
 org.controlsfx.control,
 org.controlsfx.control.action,
 org.controlsfx.control.cell,
 org.controlsfx.control.decoration,
 org.controlsfx.control.spreadsheet,
 org.controlsfx.control.table,
 org.controlsfx.control.table.model,
 org.controlsfx.control.textfield,
 org.controlsfx.dialog,
 org.controlsfx.glyphfont,
 org.controlsfx.property,
 org.controlsfx.property.editor,
 org.controlsfx.tools,
 org.controlsfx.validation,
 org.controlsfx.validation.decoration
Bundle-RequiredExecutionEnvironment: JavaSE-1.8
Require-Bundle: org.eclipse.fx.javafx;bundle-version="2.2.0";visibility:=reexport
Bundle-ActivationPolicy: lazy

I suggest to use package imports instead of require-bundle but it is
important that you all packages referenced are imported else OSGi does
not know from where it should load the references.

I'm more and more leaning towards NOT using "org.eclipse.fx.javafx" and
the OSGi Hooks in a e4+JavaFX application but starting Equinox with
-Dorg.osgi.framework.bundle.parent=ext.

This makes:
a) all package imports needless
b) other stuff like Nashorn work appropriately

The only thing left which requires "org.eclipse.fx.javafx" is when you
try to integrate into the Eclipse IDE or any other Equinox-Application
which requires to launch with the obscure default classloading strategy.

Thoughts?

Thanks Christoph,
Its working! You are right, "org.eclipse.fx.javafx" plugin dependency was missing in MANIFEST.MF.
I was importing all javafx classes in MANIFEST.MF like below which do not work.

...
..
Import-Package: javafx.animation;version="2.2.0",
 javafx.application;version="2.2.0",
 javafx.beans;version="2.2.0",
 javafx.beans.binding;version="2.2.0",
....

Cheers!
Mandar

The class you wanted to load was coming from com.sun.... - if you'd had
imported those as well import-package would have worked as well!

yes, ur right Tom, after importing com.sun.... packages it is working too without "org.eclipse.fx.javafx" plugin dependency.
I was not clear about need of importing 'com.sun..' packages, I just picked up entries from the manifest of my application, which is generated by wizard!

The wizard only adds "API" packages. com.sun.... is an internal NONE-API
package which has to be used with caution, it can vanish ANY time, I'm
using it myself because sometimes you have no other choice but it is NOT
good practice, so the wizards will never add it by default!
