Dependency Problem? [message #667667] Sat, 30 April 2011 17:58 Go to next message
Eclipse UserFriend
Hello,

I have a problem with dependencies on my Web Application.
So, I made an Dynamic Web Application which uses bundles on virgo.
This application provides rest services thanks to Jersey. This services uses bundles on virgo.
This application works perfectly on Linux.

I tried to use it on Windows 7 with the same virgo server and the same .WAR (copy/past/clean/run)
I always get an error saying that it doesn't find a class from a bundle which is in virgo (repository/usr). There is no compile error.
If a comment the line which uses this bundle, no error.

Have you an idea about this problem? Did i forget a step?

I will give you an example:

import javax.ws.rs.core.Application;

public class TestApplication extends Application {

	private Set<Class<?>> classes;
	
	private Set<Object> singletons;
	
	public TestApplication ()
	{
		classes = new HashSet<Class<?>>();
		singletons = new HashSet<Object>();
		classes.add(Manager.class);
		singletons.add(new Manager());
		APlugin plug = new APlugin();
		
	}
	
	@Override
	public Set<Class<?>> getClasses() {
		return classes;
	}
	
	@Override
	public Set<Object> getSingletons() {
		return singletons;
	}
	
}



import javax.ws.rs.GET;
import javax.ws.rs.PUT;
import javax.ws.rs.Path;
import javax.ws.rs.PathParam;
import javax.ws.rs.Produces;
import javax.ws.rs.core.MediaType;

@Path("test")
public class Manager {
		

	@GET
        @Path("/hello")
	@Produces(MediaType.TEXT_HTML)
	public String Test()
	{
		
		return "Hello World!";
	}
	
}

APlugin is an import-bundle from virgo.
If I comment this line, all is working on Windows. But I need this plugin.
What did i forget?

When migrating from Linux/Unix to Windows the problems are usually caused by wrong path separators. Can you check that you have correct paths in all files?

It seems to me that in this snippet:

Quote:
<init-param>
<param-name>javax.ws.rs.Application</param-name>
<param-value>TestApplication </param-value>
</init-param>


the param-value has additional whitespace before the closing tag: "TestApplication "

I checked all my files.
I don"t see any problem.

My fault when copy/past ^^

I tried something: I move my bundle call from TestApplication to my service Test.

Now I have no initialisation error.
I have a class not found error (I think initialisation was caused by not found error):

APlugin plug = new APlugin() was just an example.
The real line is: CustomizationsCatalog catalog = new CustomizationsCatalog(); from Modisco Plugin.

But that works on Linux. Why?

You have imports for "org.eclipse.gmt.modisco" packages right?
