[equinox-dev] DiscoveryWizard/CatalogViewer questions

Hello,

 

I am new to Eclipse and need some help.  I’m trying to embed the CatalogViewer into a form and am having no luck.  Instead of having the updater in a separate wizard dialog, we’d like to have it accessible from a tabbed dashboard form.

 

I’ve tried the example in the following location:

 

http://wiki.eclipse.org/Equinox/p2/Discovery

 

I am not able to locate the libraries for RepositoryDiscoveryStrategy, so it is unresolved.  Therefore, I tried replacing it with RemoteBundleDiscoveryStrategy which was found and resolved from the editor.  From anther Discovery example I was referencing, it used www.eclipse.org/equinox/p2/testing/updateSite for the URL.  Is this still accessible for testing?

 

Here is a small code snippet:

 

public void createPartControl(Composite parent)

    {

 

                Catalog catalog = new Catalog();

                catalog.setEnvironment(DiscoveryCore.createEnvironment());

                catalog.setVerifyUpdateSiteAvailability(false);

 

                // add strategy for retrieving remote catalog

                RemoteBundleDiscoveryStrategy remoteDiscoveryStrategy = new RemoteBundleDiscoveryStrategy();

                remoteDiscoveryStrategy.setDirectoryUrl("www.eclipse.org/equinox/p2/testing/updateSite");

                catalog.getDiscoveryStrategies().add(remoteDiscoveryStrategy);

 

//            RepositoryDiscoveryStrategy strategy = new RepositoryDiscoveryStrategy();

//            strategy.addLocation(new URI("www.eclipse.org/equinox/p2/testing/updateSite"));

//            catalog.getDiscoveryStrategies().add(strategy);

               

                CatalogConfiguration configuration = new CatalogConfiguration();

                configuration.setShowTagFilter(false);

 

                DiscoveryWizard wizard = new DiscoveryWizard(catalog, configuration);

                WizardDialog dialog = new WizardDialog(WorkbenchUtil.getShell(), wizard);

                dialog.open();

 

 

I’ve also tried creating my own CatalogViewer.  Here is another code snippet:

 

catalog = new Catalog();

 

                                // look for descriptors from installed bundles

                                catalog.getDiscoveryStrategies().add(new BundleDiscoveryStrategy());

 

                                // look for remote descriptor

                                String directoryUrl = "www.eclipse.org/equinox/p2/testing/updateSite";

                                if (directoryUrl != null && directoryUrl.length() > 0)

                                {

                                                RemoteBundleDiscoveryStrategy remoteDiscoveryStrategy = new RemoteBundleDiscoveryStrategy();

                                                remoteDiscoveryStrategy.setDirectoryUrl(directoryUrl);

                                                catalog.getDiscoveryStrategies().add(remoteDiscoveryStrategy);

                                }

 

                                catalog.setEnvironment(DiscoveryCore.createEnvironment());

                                catalog.setVerifyUpdateSiteAvailability(true);

                               

                                configuration = new CatalogConfiguration();

                                configuration.setShowTagFilter(tags.size() > 0);

                                configuration.setSelectedTags(tags);

 

                               container = new Composite(parent, SWT.NONE);

                                GridLayoutFactory.fillDefaults().margins(0, 0).applyTo(container);

                               

                                catalogViewer = new CatalogViewer(catalog, getEditorSite(), (IRunnableContext) container, configuration);

                                catalogViewer.setMinimumHeight(/*MINIMUM_HEIGHT*/480);

                                catalogViewer.createControl(parent); 

 

 

There is very little documentation regarding this technology, so any information you can send me would be greatly appreciated.

 

Thanks so much,

Stephanie
