I don't have any id's on the Fxml file and the tutorial's one doesn't have it either, i created FilmeOverview.fxml as AnchorPane and RootLayout as BorderPane, I tried changing the position of the method but it doesn't work, does anyone know how to fix this?

Edit 2: Here's rootLayout.fxml:

<?xml version="1.0" encoding="UTF-8"?>

<?import javafx.scene.control.Menu?>
<?import javafx.scene.control.MenuBar?>
<?import javafx.scene.control.MenuItem?>
<?import javafx.scene.layout.AnchorPane?>

<BorderPane prefHeight="500.0" prefWidth="800.0" xmlns="http://javafx.com/javafx/8.0.171" xmlns:fx="http://javafx.com/fxml/1">
   <children>
      <MenuBar layoutY="2.0" prefHeight="25.0" prefWidth="800.0">
        <menus>
          <Menu mnemonicParsing="false" text="Arquivo">
            <items>
              <MenuItem mnemonicParsing="false" text="Fechar" />
            </items>
          </Menu>
          <Menu mnemonicParsing="false" text="Editar">
            <items>
              <MenuItem mnemonicParsing="false" text="Deletar" />
            </items>
          </Menu>
          <Menu mnemonicParsing="false" text="Ajuda">
            <items>
              <MenuItem mnemonicParsing="false" text="Sobre" />
            </items>
          </Menu>
        </menus>
      </MenuBar>
   </children>
</AnchorPane>

This is not a duplicate, changing the import doesn't fix it, i still get

Caused by: javax.xml.stream.XMLStreamException: ParseError at [row,col]:[31,3]

    Edit your question to add the code for your FXML. My guess is that the FXML doesn't have an [import statement](https://docs.oracle.com/javase/8/javafx/api/javafx/fxml/doc-files/introduction_to_fxml.html#instance_declaration_elements) for `javafx.scene.layout.BorderPane`. – jewelsea May 22 '18 at 01:38

    Most likely your FXML doesn't have the import statement for `BorderPane`. – Jai May 22 '18 at 01:39
  • There is no `BorderPane` defined in the fxml. Use `AnchorPane rootLayout` – c0der May 22 '18 at 02:51
  • That looks like `FilmeOverview.fxml`, the problem is in `RootLayout.fxml`. – Jai May 22 '18 at 03:12
  • Just added rootlayout, i tried importing borderpane as , but it doesn't work, is there a specific way to import borderpane? – Eduardo Abreu May 22 '18 at 03:29

    Yes, stick a period where you put a space between 'layout' and 'BorderPane' – Sean F May 22 '18 at 03:59
  • Now i'm getting this "Caused by: javax.xml.stream.XMLStreamException: ParseError at [row,col]:[31,3]", the question is not duplicate as it is not the same as my problem :/ – Eduardo Abreu May 22 '18 at 11:39

You have a couple of issues:

  1. The FXML doesn't have an import statement for javafx.scene.layout.BorderPane.
  2. Your rootLayout.fxml file is invalid FXML. You close the BorderPane element with an AnchorPane tag.
  3. You define the contents of the border pane as children, where they are supposed to be defined by position.

Sample valid FXML with the above issues fixed:

<?xml version="1.0" encoding="UTF-8"?>

<?import javafx.scene.control.*?>
<?import javafx.scene.layout.BorderPane?>

<BorderPane prefHeight="500.0" prefWidth="800.0" xmlns="http://javafx.com/javafx/8.0.171" xmlns:fx="http://javafx.com/fxml/1">
    <top>
        <MenuBar layoutY="2.0" prefHeight="25.0" prefWidth="800.0">
            <menus>
                <Menu mnemonicParsing="false" text="Arquivo">
                    <items>
                        <MenuItem mnemonicParsing="false" text="Fechar" />
                    </items>
                </Menu>
                <Menu mnemonicParsing="false" text="Editar">
                    <items>
                        <MenuItem mnemonicParsing="false" text="Deletar" />
                    </items>
                </Menu>
                <Menu mnemonicParsing="false" text="Ajuda">
                    <items>
                        <MenuItem mnemonicParsing="false" text="Sobre" />
                    </items>
                </Menu>
            </menus>
        </MenuBar>
    </top>
</BorderPane>

As an aside, I recommend downloading Gluon SceneBuilder and using that to edit your FXML.

Also note, some IDEs, such as IntelliJ, include code completion, type checking and syntax checking which would highlight many of the above errors in your document when you load the file into the IDE.

  • Thank you very much! For some reason god knows why, my FXML file looked like that, I changed my project's folder and tried deleting/creating the file, putting it in a notepad before, and copying from that, i don't know if things got mixed up in the process but i'm using Gluon's SceneBuilder. – Eduardo Abreu May 22 '18 at 17:47
