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:

[ since 9.0.0 ]
Prerequisite
Settings in the ZK application
For security reasons, we need to set the origin server white list, which means only the predefined web application could access our ZK application. We use library property to set the allowed origin (In zk.xml).
For example:
<library-property>
<name>org.zkoss.web.servlet.http.embedded.AllowOrigin</name>
<value>http://localhost:9000</value>
</library-property>
Another setting is that we should define the target URL. Then all the HTTP requests in ZK would be redirected to the correct URL.
For example:
<library-property>
<name>org.zkoss.web.servlet.http.embedded.TargetURL</name>
<value>http://localhost:8080/zktest</value>
</library-property>
Settings in the other application
When using Embedded ZK, there might be some ZK resource URLs start with "/", which means that it would try to load the resource from our non-ZK application.
To deal with this problem, we should handle the requests whose target is ZK application by redirecting those requests to the ZK URL. We could use Nginx or some apache solutions. See more about the update-uri.
Example
After doing all the settings in the ZK application and the non-ZK application, now we could embed ZK pages in our HTML file. <syntax lang="html" hi="11"> <!DOCTYPE html> <html> <head> <meta charset="UTF-8"> <title>Title</title> </head> <body>
Loading...
<script defer src="http://localhost:8080/zktest/test.zul?zk.domId=embeddedZK"></script> </body> </html> </syntax>
