Hello,
First of all - I'm a complete newbie to jBoss, first time ever trying to get a test-enviroment up and running. I have the jboss-7.1.1-Final application server running on a Linux box. And as a first project just want to create a simple webservice using javax.ws but I can't get the application to deploy, I'm using ant to build a simple .war file and then copying into {JBOSS_HOME}\standalone\deployments. However I get the exception:
23:28:20,665 ERROR [org.apache.catalina.core.ContainerBase.[jboss.web].[default-host].[/webservice]] (MSC service thread 1-1) Servlet /webservice threw load() exception: java.lang.InstantiationException

public String sayPlainTextHello() {
return "Hello Jersey";
}
// This method is called if XML is request
@GET

public String sayXMLHello() {
return "<?xml version=\"1.0\"?>" + "<hello> Hello World" + "</hello>";
}
// This method is called if HTML is request

public String sayHtmlHello() {
return "<html> " + "<title>" + "Hello World" + "</title>"
+ "<body><h1>" + "Hello World" + "</body></h1>" + "</html> ";
}
}
