我们正在从Eclipse 3.5 RCP迁移到Eclispse Mars RCP。
在eclipse 3.5 RCP中，我们能够在32位和64位机器上启动我们的应用程序，即使产品导出是在32位或64位日食中完成的。 但是对于Eclipse Mars RCP，如果我们使用64位eclipse导出产品，那么它不能在32位机器上工作，而且它在64位机器上工作正常。与此类似，如果我们使用32位eclipse输出产品，它在32位机器上工作正常，而且它不能在64位工作
我在eclipse mars 64bit版本中使用导出产品向导导出项目。之后，我将该产品加入战争并在服务器中部署了相同的产品。通过使用jnlp文件，产品可以成功下载到本地客户端计算机。它在64位机器上成功推出。但是在32位机器上启动应用程序，我们得到了下面提到的异常。

在谷歌搜索后，我们发现如果我们在导出产品期间添加了插件文件夹中存在的org.eclipse.update。* jars，它可能会解决此问题。添加上面提到的问题后解决了，但得到org.eclispe.swt错误。
