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～～
