I'm having the following error while running a new spring boot application with zk:

it seems some of the information you pasted got lost, can you please try to fix this?

hawkchen commented 3 months ago

According to java.lang.NoClassDefFoundError: org/zkoss/zk/ui/http/HttpSessionListener, you might not include zk dependency.

dirkdeyne commented 3 months ago

Add zkbind as dependency and you should be OK. 

<dependency>
   <groupId>org.zkoss.zk</groupId>
   <artifactId>zkbind</artifactId>
   <version>${zk.version}</version> <!-- latest version = 10.0.0-jakarta -->
</dependency>

But you are correct the wiki page Create_and_Run_Your_First_ZK_Application_with_Spring_Boot does NOT mention this.

Note: zkbind-dependency has a provided-scope in the zkspringboot-starter pom
