Dear Lance, I am a bit lost with the Atmosphere Demo.
I am following the instructions here https://github.com/uklance/tapestry-atmosphere but there are several issues. As a starting point I use the Maven Archetype 5.4.3 for eclipse. Within eclipse I use jetty 6.1.16. Then I adjust the pom.xml with the given snipped setting the version to 0.0.6. If I just try to start the App without adding one line of atmosphere specific code it crashes with this error: [ERROR] failed app java.lang.NoClassDefFoundError: org/atmosphere/cpr/AtmosphereResourceFactory at java.lang.Class.forName0(Native Method) at java.lang.Class.forName(Class.java:348) at org.apache.tapestry5.ioc.RegistryBuilder.add(RegistryBuilder.java:159) at org.apache.tapestry5.ioc.IOCUtilities.addModulesInList(IOCUtilities.java:132) at org.apache.tapestry5.ioc.IOCUtilities.addModulesInManifest(IOCUtilities.java:105) at org.apache.tapestry5.ioc.IOCUtilities.addDefaultModules(IOCUtilities.java:76) [...] The next issue is that I can not add the <async-supported>true</async-supported> line to the web.xml because I get the following error massage. cvc-complex-type.2.4.a: Invalid content was found starting with element 'async-supported'. One of '{"http:// java.sun.com/xml/ns/j2ee":init-param}' is expected. This is probably because the new web-app definition looks like this: <web-app xmlns="http://java.sun.com/xml/ns/j2ee"; xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"; xsi:schemaLocation="http://java.sun.com/xml/ns/j2ee http://java.sun.com/xml/ns/j2ee/web-app_2_4.xsd"; version="2.4"> So I am a bit lost. It looks like the description is geared toward older versions of tapestry. But it would be really wonderful if there would be a short explanation how to use this very advanced project in what I think is the "normal" starting point for a tapestry project.
