Please make sure the URL is correct. It should look like this: 
http://localhost:8080/guvnor-5.5.0.Final-jboss-as-7.0/rest/packages/restPackage1/versions

BTW, you can find a lot code examples from this test: 
https://github.com/droolsjbpm/guvnor/blob/5.5.x/guvnor-webapp-drools/src/test/java/org/drools/guvnor/server/jaxrs/BasicPackageResourceIntegrationTest.java

Hope this helps,
Jervis
