Java / Wicket: compiling basic Hello World with resources

Question

I follow 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 is as follows:

 $ 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 into a war file and load it into Jetty, I get 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.Component.getMarkup(Component.java:737) at org.apache.wicket.Component.internalRender(Component.java:2344) at org.apache.wicket.Component.render(Component.java:2307) 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 to specify in my POM file to include an html file?

My POM is now 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" xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 http://maven.apache.org/xsd/maven-4.0.0.xsd"> <modelVersion>4.0.0</modelVersion> <groupId>wicketTest</groupId> <artifactId>wicketTest</artifactId> <version>1.0-SNAPSHOT</version> <packaging>war</packaging> <dependencies> <dependency> <groupId>org.apache.wicket</groupId> <artifactId>wicket-core</artifactId> <version>6.10.0</version> </dependency> </dependencies> </project> 

Answer 1

The solution is if you want your HTML code at the best practice gate site (with your classes) to add this to your pom's build section.

 <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> 

Answer 2

You must place the HelloWorld.html file in the src/main/webapp folder. Thus, it will be included in the military file
