I tried creating a JavaFX project in Eclipse and as long as I didn't change the default file location everything worked fine.
This is the newly craeted project
I want instead to put the SceneControllers in a different package from Main, and .fxml files in another package.
I want it to become more like this
Expected folders
But when i run the app i get this error
`
java.lang.NullPointerException: Location is required.

So i tought the issue was to specify the location of the "Sample.fxml" file, and at line 14 wrote:
AnchorPane root = (AnchorPane)FXMLLoader.load(getClass().getResource("../Sample.fxml"));
And got this error:
`

The new error is
ClassNotFoundException: application.SampleController
which occurs when you try to load the FXML, specifically on line 5 of Sample.fxml.
When you moved your controller class SampleController from the application package to the application.controllers package, you changed its fully-qualified class name. So you need to change the fx:controller attribute in the FXML file (on line 5) accordingly:
fx:controller="application.controllers.SampleController"
As an aside, note that the resource path you are using for the FXML file is not valid, as .. is not a valid resource name. It might work while you are still running the application from the file system, but will not work if you bundle it as a jar file. See How do I determine the correct path for FXML files, CSS files, Images, and other resources needed by my JavaFX Application?

Good day,
I am new to Talend, I am trying to create a Schema for tFileInputDelimited component. The Schema is trying to read a text file from a folder.
However, during step 3 on creating this Schema, I am hitting some class not found exception:

For java program, then I will know I need to import this library into my project, like adding the gradle implementation script from Maven website.
But how about this talend? Is it I need to go some where to download the jar and import into Talend Studio?
I am trying to use Eclipse to run a COMSOL model and I have read the guide from programming reference manual. However, Eclipse always report the error as follows,

I believe I have imported the JAR files correctly and set the path for the project and it seems that the error is due to lack of source file for COMSOL API JAR files. I have checked those JAR file and found they are indeed all class files without definition. How can I solve this problem? Thanks!

What could be the fix for this? There's no such jar anywhere.
It looks like the bytecode modification didn't yet kick in.
(we modify GAE API jar on the fly the first time, as we need some bytecode hacks)
So I fired up IntelliJ and created a new libgdx project, imported it and everything and then I tried to run the DesktopLauncher to see if it would work and I got this error message:

It was working fine before, plus I checked the assets folder in both "core" and "android" folders and they both had the badlogic.png file in them. What could be going on?
I guess you set everything up according to tutorials so I assume that everything was initially correct. Nevertheless some things like linked Assets folder is simply not imported.
You can try the method described here. To be honest I didn't tried it myself but some people were successfully using it.
(See here for a discussion concerned with your problem in general)

What is causing this? I have the docx4j jar in my WAR for sure, and it is there in the web-inf lib folder as well.
You're getting a java.lang.NoClassDefFoundError, not a java.lang.ClassNotFoundException. The class is being loaded, but a class that it depends on (directly or indirectly via another class) isn't there. You're most likely missing a jar that docx4j requires as a dependency.
Make sure that you have the correct version of docx4j and that there is absolutely no other version of docx4j in your classpath, there may be a version of this lib that did not have the 'Content' class implemented.
