Java/Wicket: Compile Basic Hello World with Resources
I am following this example of a Hello World Wicket application
https://www.ibm.com/developerworks/web/library/wa-aj-wicket/
In particular I placed HelloWorld.html in my source directory next to HelloWorld.java.
My file structure looks like this:
$ tree
.
├── pom.xml
├── src
│ ├── main
│ │ ├── java
│ │ │ └── com
│ │ │ └── example
│ │ │ └── wicket
│ │ │ ├── HelloWorld.html
│ │ │ ├── HelloWorld.java
│ │ │ └── HelloWorldApplication.java
│ │ ├── resources
│ │ └── webapp
│ │ └── WEB-INF
│ │ └── web.xml
│ └── test
│ └── java
└── wicketTest.iml
However when I compile this to a war file, and load in Jetty, i recieve this error, in the browser:
Unexpected RuntimeException
Last cause: Can not determine Markup. Component is not yet connected to a parent. [Page class = com.example.wicket.HelloWorld, id = 4, render count = 1]
Stacktrace
Root cause:
org.apache.wicket.markup.MarkupNotFoundException: Can not determine Markup. Component is not yet connected to a parent. [Page class = com.example.wicket.HelloWorld, id = 4, render count = 1]

at org.apache.wicket.Page.renderPage(Page.java:1010)
When I look in the war file I notice that the html file is missing:

How do I specify in my POM file to include the html file?
My POM right now is minimal:
<?xml version="1.0" encoding="UTF-8"?>
<project xmlns="http://maven.apache.org/POM/4.0.0"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"

Answer
The solution, if you want your HTML in the wicket best practice place (with your classes) is to add this to the build section of your pom.
<build>
<resources>
<resource>
<filtering>false</filtering>
<directory>src/main/resources</directory>
</resource>
<resource>
<filtering>false</filtering>
<directory>src/main/java</directory>
<includes>
<include>**</include>
</includes>
<excludes>
<exclude>**/*.java</exclude>
</excludes>
</resource>
</resources>
</build>
</project>
