Embedded ZK Application

Embedded ZK Application


Employment/Purpose

Instead of using iframe, there is a new way to use ZK in a non-ZK web container. For example, we could use NodeJs, Python, etc. as the web application, and embed another ZK application in the web pages.

  • Available for ZK:
  • http://www.zkoss.org/product/zkhttp://www.zkoss.org/whyzk/zkeeVersion ee.png
[ since 9.0.0 ]

Prerequisite

Settings in the ZK application

We use library property to enable the embedded feature. For example: (In zk.xml)

<library-property>
	<name>org.zkoss.web.servlet.http.embedded.enabled</name>
	<value>true</value>
</library-property>

Settings in the other application

When using Embedded ZK, we need to handle all of the requests, whose target URL point to ZK application.

To deal with this problem, we should handle the requests whose target is ZK application.

We could use Nginx or some apache solutions to redirect those requests to the ZK URL.

For example, we could add the following settings in Nginx : (ZK application - zktest)

location / {
  #Non-ZK Application
  proxy_pass http://127.0.0.1:9000; 
}

location /zkEmbeddedDemo/ {
  #ZK Application
  proxy_pass http://127.0.0.1:8090;
}

Example

After doing all the settings in the ZK application and the non-ZK application, now we could embed ZK pages in our web application. <syntax lang="html" high="11,13"> <!DOCTYPE html> <html> <head> <meta charset="UTF-8"> <title>Title</title> </head> <body>

Loading...

<script src="/zk90test/zkau/web/js/zkmax/embedded/embedded.js"></script> <script> zEmbedded.load('embeddedZK', 'http://localhost/zk90test/demo.zul'); </script> </body> </html> </syntax>

In line 11, we use <script> to load ZK embedded JS.

In line 13, we call zEmbedded to load the demo.zul, and the "embeddedZK" means that the embedded ZK page would be rendered in the corresponding DOM Element (DOM id).
