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);

Integration sample

Create “sample.jsp” file:

<%@ page language="java" contentType="text/html; charset=UTF-8" pageEncoding="UTF-8" %>
<html>
  <head>
    <title>Sample test</title>
    <script>
      function refresh() {
        alert('executing refresh');
        parent.parent.refreshFolder();
        alert('done');
      }
    </script>
  </head>
  <body>
    <a href="#" onclick="refresh()">Refresh UI</a>
  </body>
</html>

Copy “sample.jsp” file into your “$TOMCAT_HOME/webapps/openkm/” folder.

Enable the extension named “External Tab Document”, take a look at Enable extensions and External tab document extension. Remember you must enable the extension from the Profiles.

Configure the parameter extension.external.tab.document with the value below.

Field / Property	Type	Description
extension.external.tab.document	List	Each row is a couple of values with a tab content declaration, the format is: name;url Sample;http://localhost:8180/openkm/test.jsp
