rcp中调eclipse的帮助

1.在ApplicationActionBarAdvisor类中定义Action：

private IWorkbenchAction helpContentsAction;

2.在makeActions方法中注册：

helpContentsAction = ActionFactory.HELP_CONTENTS.create(window);
register(helpContentsAction);

3.在fillMenuBar方法中添加菜单：

MenuManager helpMenu = new MenuManager("&Help", IWorkbenchActionConstants.M_HELP);

menuBar.add(helpMenu);

helpMenu.add(helpContentsAction);

4.在.product文件中配置必须的这七个依赖项：

1. org.apache.lucene
2. org.eclipse.help.appserver
3. org.eclipse.help.base
4. org.eclipse.help.ui
5. org.eclipse.help.webapp
6. org.eclipse.tomcat
7. org.eclipse.ui.forms
万事ok～～
