Build a RESTful Webservice in less than 5 minutes

There are quite some tutorials around about building and exposing a RESTful Webservice, but some of them are outdated and make you wade through complex dependencies and tinkering with deployment descriptors and web.xml files. But using RESTeasy, the JBoss implementation that is fully compliant with the JAX-RS 2.0 JCP specification, and Eclipse you can build a simple webservice (“hello world”) with less than 10 lines of sourceode with annotations and no web.xml used in a few minutes and run it on Wildfly.

Lets build a webservice that creates random numbers.

Create a JIRA client application with Netbeans

I want to embed the creation of JIRA issues into my web application. There are 2 option, as XML-RPC or SOAP client. I decide for the latter one as being the more-up-to-date technology.

Using Netbeans it is usually quite simple to create a WS client, just give the WSDL address and NB will create all required code for you. Btw, you need to install the JAX-RPC plugin, NB out-of-the-box only supports JAX-WS.
Add the “latest” build to your Netbeans plugin settings and you will find the plugin. (

JAX-RPC Webservices

But in the case of the JIRA WSDL (you can test with or your own JIRA server) it fails.
While creating the WS client code it duplicates a number of variables.

/media/NetbeansProjects/Webservices/JiraDemo/build/generated-sources/jax-rpc/jiraws/ ns1_fault_QNAME is already defined in jiraws.JiraSoapService_deletePermissionScheme_Fault_SOAPSerializer
private static final javax.xml.namespace.QName ns1_fault_QNAME = new QName("http://xxxxxxx/rpc/soap/jirasoapservice-v2", "fault");


My temporary workaround: I create the Java application in Eclipse, add the WS there and import the project afterwards into NB. This works, but you loose the extra functions to handle WS in Netbeans. So on the long way, I hope someone can fix the plugin.
