Errai communication error !!!
by Ing. Sandy Noa Cabrera
>From some days ago I was trying to make an errai application from scratch, I'm working with version 1.1-Final and Eclipse Helios (including Maven and GWT pluggins) but when I generate the archetype like this:
mvn archetype:generate -DarchetypeArtifactId=jboss-javaee6-webapp -DarchetypeGroupId=org.jboss.weld.archetypes -DarchetypeVersion=1.0.1.Beta1
and load the project into Eclipse, finally if I attempt to run it like a Web Application I get a "Message Bus Error" according to communication. View the picture for details.
Also, when I try to run the first Hello World example that come with doc I get the same error in communication,
could somebody help me ???
Thanks anyway...
