I'm trying to get a simple RestEasy project to work in Eclipse (with Jboss Tools) and Jboss 5.1.0. To get going, I've created a simple Dynamic Web Project. In the project, I've include the following in WEB-INF/web.xml:

<context-param>
    <param-name>resteasy.scan</param-name>
    <param-value>true</param-value>
</context-param>
<listener>
    <listener-class>org.jboss.resteasy.plugins.server.servlet.ResteasyBootstrap</listener-class>
</listener>

<servlet>
    <servlet-name>Resteasy</servlet-name>
    <servlet-class>org.jboss.resteasy.plugins.server.servlet.HttpServletDispatcher</servlet-class>
</servlet>

<servlet-mapping>
    <servlet-name>Resteasy</servlet-name>
    <url-pattern>/*</url-pattern>
</servlet-mapping>

On trying to start the above project (in Jboss running in Eclipse), I get the following exception in the Console:

14:10:17,614 ERROR [AbstractKernelController] Error installing to Real: name=vfsfile:/Users/groove/Documents/workspace/.metadata/.plugins/org.jboss.ide.eclipse.as.core/JBoss_5.1_Runtime_Server1326046666357/deploy/blankWeb.war/ state=PreReal mode=Manual requiredState=Real

Thanks in advance.

First of RestEasy is only supported out the box from version 6 of JBoss IIRC.

Heres a link to the rest easy website if you do need to download it. http://www.jboss.org/resteasy

  1. I make the assumption that you allready have a Preferences>Server>Runtime Environment> configured for JBoss. If not do that first.

  2. Caused by: java.lang.NoClassDefFoundError: javax/servlet/http/HttpServlet. This tells me that if you got 1 above right you have not added it to your buildpath yet as Properties>Java Build Path>Add Library>Server Runtime. The runtime contains the servletapi.

  3. org.jboss.resteasy.plugins.server.servlet.ResteasyBootstrap lives in the resteasy-jaxrs-2.3.0.GA.jar jar. Dump it in your WEB_INF/lib folder. DO NOT add it to your build path via Eclipse. Eclipse takes care of that it self.

  4. org.jboss.resteasy.plugins.server.servlet.HttpServletDispatcher. Same as 3 above.

  5. <param-name>resteasy.scan</param-name> This functionality I believe is a runtime dependency and lives in the scannotation-1.0.3.jar. Dump it in WEB_INF/lib. Again, Eclipse takes care of the classpath.

  6. This is after all a JAX-RS project so dump jaxrs-api-2.3.0.GA.jar to your in WEB_INF/lib. This will bring in the @Path, @Get, etc annotations for use in your resource classes.

  7. I also have jaxb-api-2.2.3.jar, javassist-3.8.0.GA.jar and jackson-jaxrs-1.8.5.jar in my WEB-INF/lib but from here on out it depends what functionality you are going to use and which providers loggers etc.

I hope I nailed the essentials jars, if anyone spots a missing one please correct. My first try at JAX-RS I just dumped the whole shebang of 56 jars in WEB-INF/lib (Not a good idea)

Have Fun!!
