UI platform independent

 
Write UI sourcce code for your screens once and start the application as Desktop, Web or Mobile solution.

  • Swing
    Applet, Webstart or Desktop
  • Vaadin
    HTML5/Ajax
  • iOS und Android
    Native App for Smartphone, Tablet
   
 

Quick & Easy development

 
GUI Code:
private void initializeUI() throws Exception  {
  UITable table = new UITable();
  table.setDataBook(rdbContacts);//bind to UI model
  add(table, UIBorderLayout.CENTER);
  setTitle("Contacts");
  setSize(new UIDimension(600, 500));
}
private void initializeModel() throws Throwable {
  RemoteDataBook rdbContacts = new RemoteDataBook();
  rdbContacts.setDataSource(getDatasource()); // bind to DAO „contacts“
  rdbContacts.setName("contacts"); 
  rdbContacts.open();
}

Server Code:
public IStorage getContacts() throws Exception {
  DBStorage dbsContacts = (DBStorage)get("contacts");
  if (dbsContacts == null) {
    dbsContacts = new DBStorage(); // Automatic DAO
    dbsContacts.setDBAccess(getDBAccess()); 
dbsContacts.setWritebackTable("CONTACTS"); dbsContacts.open(); put("contacts", dbsContacts); } return dbsContacts;
}
 

You don't need more code!

You write just a few lines of code for an application that manages your contacts.

  • initializeUI()
    Initialize an UITable, bind it to the model and add it to the screen. 
  • initializeModel()
    Instantiate model for contacts, bind it to the server and the DAO "contacts".
  • getContacts()
    Instantiate DAO "contacts", initialize it with database and table "CONTACTS".
 

How does it work?

         

 

feat_link_edit_input

feat text editor

 

JVx' DAO class DBStorage analyzes the data model of table "CONTACTS". This detects all data types for all columns and all foreign keys to master data tables. This metadata information are sent to the client model.

The dynamic client model, for all Daten data-bound GUI controls, uses this metadata.
Because of this mechanism, all input fields get a specific data type, and size directly from the database. Dropdown lists are created because of foreign key references to master data tables, etc.

As a result, no further source code is necessary. 
"Covention over Configuration"

Any deviation from the standard behavior can be coded accordingly.
