Question

我正在使用RCP，我的Application类中有这个'start'方法：

public class Application implements IApplication {
public Object start(IApplicationContext context) throws Exception {
    Display display = PlatformUI.createDisplay();

    try {
        // Enforcing that Spring Dynamic Modules extender is started
        Platform.getBundle("org.springframework.osgi.extender").start();  **//THIS IS LINE 26**
        int returnCode = PlatformUI.createAndRunWorkbench(display, new ApplicationWorkbenchAdvisor());
        if (returnCode == PlatformUI.RETURN_RESTART)
            return IApplication.EXIT_RESTART;
        else
            return IApplication.EXIT_OK;
    } finally {
        display.dispose();
    }

}
//More methods...
}

错误说：

我相信它是cos版本，但我在程序参数中添加了'-d32'（在运行配置中......）我不知道遗失了什么。

任何能帮助我的人，我都很感激，因为这真的是一个紧急情况。

我知道在这个程序员的世界里，我们需要分享我们的疑虑和知识。

提前致谢;）

我会使用OSGi包的起始级别来确保捆绑包正确启动。您可以通过“配置”页面上的“产品配置”设置起始级别，也可以通过config.ini属性直接在osgi.bundles文件中设置起始级别。

错误Platform.getBundle（“”）。start（）;
