OpenKM UI is developed with GWT framework what helps on calling Java methods from JavaScript.

The UI frontend Java methods are public exposed as JavaScript functions an can be used in frontend context.

How to expose Java methods to JavaScript

Static method sample

Expose static method named i18n(String property) to JavaScript as "jsI18n(String)" function:

/**
 * initJavaScriptApi
 */
native void initJavaScriptApi() /*-{
	$wnd.jsI18n = function(s) {
		return @com.openkm.frontend.client.Main::i18n(Ljava/lang/String;)(s);
	};
}-*/;

Non Static method sample

Expose non static method "executeRefresh()" from class Toolbar.java to JavaScript as jsRefreshFolder function:

In the Toolbar Java create a method named "initJavaScriptApi()":

public native void initJavaScriptApi(ToolBar toolBar) /*-{
	$wnd.jsRefreshFolder = function() {
		toolBar.@com.openkm.frontend.client.widget.toolbar.ToolBar::executeRefresh()();
		return true;
	}
}-*/;

After creating a new Toolbar object call the "initJavaScriptApi()" method:

ToolBar toolBar = new ToolBar();
mainPanel.topPanel.toolBar.initJavaScriptApi(mainPanel.topPanel.toolBar);
