Question: I use Apache as Samza framework for Kafka and I need to share the same RockDBs key-value storage between 2 Tasks.

Answer: 
Please check this codes
it should solve 

```
protected void beforePage(Form f) {

    f.setScrollableY(false);
    TableLayout.Constraint c1 = new TableLayout.Constraint();
    c1.setHeightPercentage(80);
    c1.setWidthPercentage(100);
    TableLayout.Constraint c2 = new TableLayout.Constraint();
    c2.setHeightPercentage(20);
    c2.setWidthPercentage(100);

    WebBrowser browser = new WebBrowser();
    browser.setURL("http://www.facebook.com");

    WebBrowser browser2 = new WebBrowser();
      browser2.setURL("http://www.google.com");
    f.setLayout(new TableLayout(2, 1));
    f.addComponent(c1, browser);
    f.addComponent(c2, browser2);
}

1. create tablelayout with column 1 and row 2
2. add first webbrowser and set its height to 80 %
3. and add second and set 20%
