ЭМП, работающая с Девой

Я пытаюсь использовать EMF в контейнере Virgo. В моем POM я добавил следующие зависимости:

<dependency>
    <groupId>org.eclipse.emf</groupId>
    <artifactId>org.eclipse.emf.ecore</artifactId>
    <version>2.8.0-v20120911-0500</version>
</dependency>
<dependency>
    <groupId>org.eclipse.emf</groupId>
    <artifactId>org.eclipse.emf.common</artifactId>
    <version>2.8.0-v20120911-0500</version>
</dependency>
<dependency>
    <groupId>org.eclipse.core</groupId>
    <artifactId>org.eclipse.core.runtime</artifactId>
    <version>3.6.0.v20100505</version>
</dependency>

Хотя, когда я запускаю свой сервер, я получаю следующее исключение:

[2013-04-29 15:29:56.880]  TCP Connection(6)-127.0.0.1 <DE0002E> Installation of bundle 'xxx' version '0.0.1' failed. org.eclipse.virgo.nano.deployer.api.core.DeploymentException: commit failed

И у меня такое ощущение, что Activator пытается что-то сделать, предполагая среду плагина Eclipse, хотя ее нет. Кто-нибудь успешно использовал EMF в связке Virgo? Спасибо!

Вы правы, потому что EMF работает в среде Eclipse. Мы интегрировали EMF с Virgo, выполнив следующие шаги:

  1. Создайте обертку пакета с папкой с именем lib и поместите в эту папку банки EMF. В нашем случае ставим библиотеки: org.eclipse.emf.common-2.7.0.v20110128-1409.jar, org.eclipse.emf.ecore-2.7.0.v20110128-1409.jar и org.eclipse.emf .ecore.xmi-2.6.0.v20110126-1727.jar
  2. Добавьте эти библиотеки в путь к классам пакета в MANIFEST.MF.
  3. Повторно экспортируйте пакеты EMF в свой MANIFEST.MF.

  4. Создайте класс Activator и установите реестр. Код:

    @Override
public void start(BundleContext arg0) throws Exception {
    Properties props = System.getProperties();
    props.setProperty("org.eclipse.emf.ecore.EPackage.Registry.INSTANCE",
            "org.eclipse.emf.ecore.impl.EPackageRegistryImpl");

}

@Override
public void stop(BundleContext arg0) throws Exception {
    Properties props = System.getProperties();
    props.remove("org.eclipse.emf.ecore.impl.EPackageRegistryImpl");

}

Наконец, MANIFEST.MF будет примерно таким:

Manifest-Version: 1.0
Bundle-Version: 2.7.0
Bundle-Name: EMF-Wrapper
Bundle-ManifestVersion: 2
Bundle-SymbolicName: emf-wrapper
Bundle-ClassPath: .,

Следуя приведенному выше вдохновению, я создал эту оболочку, которая выполняет свою работу. Обратите внимание, что я не включаю копию библиотек EMF, а просто добавляю их через зависимость от maven.
