JAX-RS Tutorial [message #899574]

Hi,

some minor issues/requests:

First,
I followed the instruction on [1] by setting up a target definition using the latest Integration build and hoped to skip the additional step to install the JAX-RS addon. When importing the JAX-RS example projects they complain that no plugin in the current target definition exports javax.ws.rs - which is apparently true when looking at my target file Smile

Is it possible to add javax.ws.rs bundle to the integration update site too?

Second,
after manually adding the required jaxrs plugins in my target platform, most classes compile except those that depended on "import org.eclipse.gyrex.cloud.environment.INodeEnvironment; Also the package import to "org.eclipse.gyrex.http.application.provider" cannot be resolved.

Is this import still recent for Gyrex 1.2 Integration builds?

Thanks,
Marcel

Thanks for the report Marcel! Tracked as
https://bugs.eclipse.org/386395.

A new build should be kicked automatically soon.

(Whoops, the forums "edit" feature did not update the newsgroup post.
Thus, this is a reply to a follow-up question.)

That's still required (the first only for the samples, though). It looks
like an issue in the target platform. What does the "Target Platform
State" view looks like? Can you post a screenshot? There should be a
"org.eclipse.gyrex.http" bundle which provides the
"org.eclipse.gyrex.http.application.provider" package.

Thanks,
Gunnar

The latest integration build fixed the second issue too. All classes compile and all imports work now.

Thanks Smile

I've set up a launch config which includes the whole target platform (except *test projects) including the two jax-rs sample projects. The server starts and the admin console is available under localhost:3110. However, when I try to click on any menuitem I get an 500 server error and stacktraces on the console.

One is for instance:

Osgi console says Zookeeper plugin is active.

osgi> ss zoo
"Framework is launched."

    Missing optionally imported package org.jboss.netty.channel.group_0.0.0.

When I click on the application tab, I get a different error:

    Service 'org.eclipse.gyrex.http.application.manager.IApplicationManager' is currently not available for bundle 'org.eclipse.gyrex.admin.ui.http(id 98)'

and a length stacktrace.

Console again tells me both plugins should be ok:

ss org.eclipse.gyrex.admin.ui.http
"Framework is launched."

99	ACTIVE      org.eclipse.gyrex.admin.ui.http.jetty_1.0.0.v20120702-0820

Is there anything obvious I missed?

Did you set it up like described here:

No, I didn't. I thought I looked at the applications menu after I set up the target platform the first time to see if there is a new application available - but couldn't see one. Thus I started it with "osgi framework" launch config instead of an Eclipse application. Now I have the gyrex application and the stacktraces are gone. Thanks.

Thanks for the feedback. It's actually a regular "Eclipse Application" type. I'll make sure that the tutorials are more clear about that. Maybe that should be a separate page.

the product export page should have warned me. But yes, I didn't expect the start configuration to be in the declarative services example. I skipped that page as I imported the existing projects from the JAXRS tutorial .
