~ Christian Ullenboom ~ Hinterlasse einen Kommentar

Unter der Apache Lizenz:

It is the most standards-compliant Open Source Java persistence product in existence. It is fully compliant with the JDO1, JDO2, JDO2.1, JDO2.2, JDO3, JDO3.1, JPA1, JPA2, JPA2.1 Java standards. It also complies with the OGC Simple Feature Specification for persistence of geospatial Java types to RDBMS. It utilises an OSGi-based plugin mechanism meaning that it is extremely extensible.

http://www.datanucleus.org/. Neues: http://www.datanucleus.org/documentation/news/access_platform_4_0_0_release.html:

  • Java 1.8 : Upgrade to ASM v5 to allow for Java 1.8 bytecode changes
  • Java 1.8 : support for the majority of java.time types
  • Changed the bytecode enhancement contract to use an internal definition rather than the JDO contract
  • JPA : no longer needs to have jdo-api.jar present
  • Cassandra : support for Cassandra 1.2+
  • Support for multicolumn TypeConverters (used by RDBMS, Cassandra, Excel, ODF, Neo4j, MongoDB, JSON, HBase)
  • SchemaTool : support for create/delete of a schema (where the datastore supports it)
  • RDBMS : support for HikariCP and DBCP2 connection pools
  • RDBMS : ability to use single connection per PM/EM (rather than 1 for transactional operations, and 1 for non-transactional operations)
  • RDBMS : removed the need to create JavaTypeMapping classes when the user type has a TypeConverter
  • JSON : support for embedded 1-1 relation fields/properties
  • Excel/ODF/JSON/MongoDB/Neo4j/HBase/Cassandra : move to using „core“ definition of table/columns meaning access to generalised features tested on other datastores

“Java ist auch eine Insel”, 11. Auflage, jetzt neu im Handel

~ Christian Ullenboom ~ 3 Kommentare

Cover von Java ist auch eine InselNach mehr als zwei Jahren gibt es ein Update der Insel: https://www.galileo-press.de/java-ist-auch-eine-insel_3606/. Aktualisiert auf Java 8, 1306 Seiten, ISBN 978-3-8362-2873-2, E-Book-Formate: PDF, EPUB, MOBI, Online.

Online ist das Buch nicht mehr, da es zu juristischen Auseinandersetzungen mit Mitbewerben kommen könnte. Vereinfacht ausgedrückt: Etwas verkaufen, was gleichzeitig frei ist, macht den Verlag verletzbar gegenüber Abmahnungen. Online bleibt aber weiterhin die jeweils letzte Version, also komplett wie üblich Auflage 10: http://www.tutego.de/javabuch/; das gilt auch für den 2. Band, den es ebenfalls bald im Handel geben wird.

Weiterhin ist eine PDF mit Kapitel 2 und 3 mit nahezu 300 Seiten vom 1. Band, 11. Auflage, online.

SceneBuilder 2.0 final

~ Christian Ullenboom ~ Hinterlasse einen Kommentar

SceneBuilder 2.0 ist nun final, das Beta zog sich lange hin:

It has many cool new features and was a complete rewrite from the ground up so that it can be split into parts and embedded in your favorite IDE.

Updates unter http://fxexperience.com/2014/05/announcing-scenebuilder-2-0/, http://docs.oracle.com/javase/8/scene-builder-2/release-notes/jfxsb-release_notes_2-0.htm:

  • JavaFX Scene Builder Kit. JavaFX Scene Builder Kit is an API that allows the integration of Scene Builder panels and functionalities directly into the GUI of a larger application, or a Java IDE, such as NetBeans, IntelliJ, and Eclipse. See Working with the JavaFX Scene Builder Kit for more details.

  • Ability to add custom GUI components to the Library. Custom components imported from a third party JAR file can now be added permanently to the Library of available GUI components. See Adding Custom Components to the Library for more information.

  • Support for new JavaFX 8 UI components. The new UI components, TreeTableView, DatePicker, and SwingNode, that were introduced in the Java SE 8 are now supported in Scene Builder 2.0. To see the list of JavaFX 8 UI components that are available, type FX8 in the Library panel’s search text field.

  • 3D Support. FXML documents containing 3D objects can now be loaded and saved in the Scene Builder tool. You can view and edit properties of the 3D objects using the Inspector panel. You can not, however, create new 3D objects using the Scene Builder tool. See JavaFX Scene Builder User Guide for more information.

  • Support for Rich Text. A new container, TextFlow, is now available in the Library of GUI components. You can drag multiple text nodes and other types of nodes, into the a TextFlow container. You can also directly manipulate the text nodes to re-arrange them in the container. Inline and property editing features are also available for each text node.

  • Library Panel Improvements. The default viewing option for the Library panel is a new feature that gives you the option to view all the component categories as collapsible sections.

  • Hierarchy Panel Improvements. It is now more flexible to re-parent objects from one container to another container. It is also possible to drag and drop an object from the Hierarchy Panel to the Content Panel, and vice versa. You can also now select multiple objects in the Hierarchy Panel in order to re-parent them.

  • Content Panel Improvements. You can now manipulate the components of an HBox, VBox, FlowPane, or Toolbar container directly in the Content Panel to re-order them. You can also insert a new component at any position in the container. Note that this direct manipulation is currently not available for the TilePane container.

  • Inspector Panel Improvements. Many property editors in the Inspector panel use the Suggested List dialog window, which displays a list of selectable values from which you can make a selection instead of manually entering them. For example, the CSS Style editor provides a list of applicable CSS properties, based on the currently selected object(s). List handling has also been simplified. Multi-selection of components of different types (i.e. Button + TextField) is now supported. In addition, the usability of many of the property editors, such as AnchorPane Constraints, Rotate, and Padding, have been improved.

  • Preview Window Improvements. The content in the Preview window is now automatically refreshed as the current FXML document is being edited. Hence, there’s no need to use the Refresh command in order to preview the modified UI layout.

  • Change in the Include FXML Command. When you click File from the Menu bar and then click Include, you can only select the FXML menu item if the current FXML document you are editing is saved on your system’s disk and is not empty.

gwtbootstrap3 Version 0.7 fertig

~ Christian Ullenboom ~ Hinterlasse einen Kommentar

https://github.com/gwtbootstrap3 ist eine GWT-Bibliothek mit hübschen Komponenten, einen Grid-System, siehe dazu auch https://gwtbootstrap3.github.io/gwtbootstrap3-demo/, alles ist optimiert auf Umfluss für mobile Endgeräte. Es basiert auf Twitter Bootstrap http://getbootstrap.com/. Änderungen in Version 0.7:

  • Added connivence methods to easily set margins/paddings on widgets.
  • Ensured removal of all handlers on the unLoad of widgets
  • Added methods to show/hide/toggle NavbarCollapse
  • Further styled GWT’s CellTable/DataGrid to reflect Bootstrap tables
  • Upped the dependency of GWT to 2.6.0
  • Added submit/reset methods to Form
  • Renamed all setTarget/setToggle methods to setDataTarget/setDataToggle, also any setter that referenced a data* attribute was renamed
  • Added in a check as to not load jQuery if it’s already present
  • Changed the parent of gwtbootstrap3-parent to oss-parent (org.sonatype.oss)

Was ich in meinem Code ändern musste war tatsächlich die *Data* Sache:

dismissButton.setDismiss( ButtonDismiss.MODAL ); –> dismissButton.setDataDismiss( ButtonDismiss.MODAL );

dialog.setKeyboard( true ); –> dialog.setDataKeyboard( true );

anchor.setTarget( "#" + title.hashCode() ); –> anchor.setDataTarget( "#" + title.hashCode() );

anchor.setToggle( Toggle.COLLAPSE ); –> anchor.setDataToggle( Toggle.COLLAPSE );
