I have set up the RESTEasy sample project (simple) and used the Web Service Test View to return the available options. The options are:

POST, OPTIONS

The documentation located at http://community.jboss.org/wiki/UsingtheWebServiceTester suggests that the options should be:
GET, HEAD, POST, PUT, DELETE, TRACE, and OPTIONS

The JBoss Tools Project Examples version is reported by Eclipse as:
JBoss Tools Community Project Examples 1.1.0.v20100908-1606-H23-M2 org.jboss.tools.community.project.examples.feature.feature.group

Any idea as to why the options do not include GET, HEAD, PUT, DELETE and TRACE
