ui:repeat is not working solution JSF 2.x version, How to enable ui:repeat tag

If ui:repeat tag is not working/rendered in your facelet based JSF application,
you should add the correct dependencies using Maven;

There are two approaches like as below;
one jar solution

 <dependency>
 <groupId>javax.faces</groupId>
 <artifactId>javax.faces-api</artifactId>
 <version>2.2</version>
 <scope>provided</scope>
</dependency>

or only the following two jars

 <groupId>com.sun.faces</groupId>
 <artifactId>jsf-impl</artifactId>
 <version>2.2.9</version>
</dependency>

<dependency>
 <groupId>com.sun.faces</groupId>

HSQLDB init servlet configuration web.xml and util class

HSQLDB init servlet configuration web.xml and util class

In order to configure HSQLDB in web application before accesing it, you can extends HttpServlet
and initialize it within web.xml file so HSQLDB will be available inside the application

hypersql


package hsqldb;

import javax.servlet.ServletException;
import javax.servlet.http.HttpServlet;

import org.hsqldb.Server;
import org.hsqldb.persist.HsqlProperties;

public class InitHSQLDB extends HttpServlet {

	private static final long serialVersionUID = 1L;

	private Server server = null;
	@Override
	public void init() throws ServletException {
		super.init();
		server = new Server();
		try {
			System.out.println("Start Database");
	        HsqlProperties properties = new HsqlProperties();
	        properties.setProperty("server.database.0", "jdbc:hsqldb:mem://localhost");	        
	        properties.setProperty("server.port", "9001");
	        Server server = new Server();
	        server.setProperties(properties);
	        server.start();
	        System.out.println("Database is started");
		} catch (Exception e) {
			throw new ServletException(e);
		}		
	}
	
	@Override
	public void destroy() {		
		   super.destroy();
		   server.stop();
		   server.shutdown();
	}
}
