关于Eclipse RCP的两个小问题和解决方法

1、如果你想在RCP应用程序里使用Eclipse提供的Resource Navigator（它是IDE plugin的一部分），要在WorkbenchAdvisor里加入如下代码，否则在Navigator里新建的项目和文件名都会变为空：

WorkbenchAdapterBuilder.registerAdapters();

一般加在preWindowOpen()方法里就可以了，否则可能需要手动refresh才能看到已有的项目。当然，你还要在plugin dependencies里加上org.eclipse.ui.ide和org.eclipse.ui.views，所以你的RCP程序会变得更大，这就是代价，目前这个ResourceNavigator不被鼓励用在RCP程序里，以后版本的Eclipse可能会提供更合适的插件。

2、若你在运行RCP Application时遇到以下异常：

java.lang.NoSuchMethodException: com.your.YourPlugin.<init>(org.eclipse.core.runtime.IPluginDescriptor)

at java.lang.Class.getConstructor0(Unknown Source)

at java.lang.Class.getConstructor(Unknown Source)

at org.eclipse.core.internal.plugins.PluginDescriptor.internalDoPluginActivation(PluginDescriptor.java:403)

at org.eclipse.core.internal.plugins.PluginDescriptor.doPluginActivation(PluginDescriptor.java:359)

或是：

org.eclipse.core.runtime.CoreException[1]: java.lang.ClassNotFoundException: com.your.YourApplication

at org.eclipse.osgi.framework.internal.core.BundleLoader.findClass(BundleLoader.java:404)

at org.eclipse.osgi.framework.adaptor.core.AbstractClassLoader.loadClass(AbstractClassLoader.java:93)

at java.lang.ClassLoader.loadClass(Unknown Source)

at org.eclipse.osgi.framework.internal.core.BundleLoader.loadClass(BundleLoader.java:307)

可以检查一下你是否在plugin dependencies里增加了org.eclipse.core.runtime.compatibility，我不太清楚这个plugin是做什么用的，但只要有它在我的RCP Application就无法启动。
最后，如果希望在Eclipse的console里显示log而不是直接写入到文件中，可以在运行时加上-consoleLog参数。

第二点，因为你用了过时的plugin.xml格式或api，使用eclipse 3.0.x以上的格式和api就可以了。

谢谢你的提示，我查了一下：
"What is the purpose of org.eclipse.core.runtime.compatibility?

The move in 3.0 to an OSGi-base runtime made some of the existing core runtime APIs obsolete. Wherever possible, obsolete APIs in the org.eclipse.core.runtime.* packages, along with the implementation behind it, were moved from the org.eclipse.core.runtime plug-in to a new org.eclipse.core.runtime.compatibility plug-in. By default, newly-created plug-ins depend on org.eclipse.core.runtime and are expected to use only non-deprecated runtime APIs. On the other hand, existing plug-ins migrating from 2.1 will depend by default on org.eclipse.core.runtime.compatibility and can make use of the old APIs as well (the org.eclipse.core.runtime.compatibility plug-in re-exports APIs of org.eclipse.core.runtime). While the org.eclipse.core.runtime.compatibility plug-in is likely to be included in Eclipse IDE configurations, it's dead wood that's unlikely to be included in products based on RCP configurations."
BTW，你在sm的blog还能用吗？

通过IPagedLaytou可以很方便的添加Resource Navigator，RN可以新建项目文件什么的。

那我要是想在RCP一开始时的菜单栏或者工具栏里有和RN类似的菜单和工具，有什么内定的方法或者定义好的按钮组件吗？没有的话我要自己编码的话怎么和RN联系起来呢？

能不能给个思路什么的，多谢啦^o^

#4楼 [楼主] 2005-03-21 09:26 八进制

很好的问题。你可以通过org.eclipse.ui.actions.ActionFactory找到一些内建命令，例如ActionFactory.QUIT、ActionFactory.PREFERENCES等等，还有一些在org.eclipse.ui.actions.ContributionItemFactory里，例如ContributionItemFactory.VIEWS_SHORTLIST。

我搞定菜单功能啦，内嵌的ActionFactory非常方便啊。
只是我看你的截图里Outline，Properties这些视图也都是英文的嘛，难道不能改吗？我的Eclipse是中文呢的呀。我看运行参数里也有-nl zh_CN这样的表示

#6楼 [楼主] 2005-03-22 13:59 八进制

Outline和Property的文字org.eclipse.ui.views工程的plugin.properties里定义的，改为中文应该是通过fragment项目来实现，也就是提供一个语言包。
或者在你的项目plugin.xml里重新定义它们，可能也能改名，我没试过哦。

#9楼 [楼主] 2006-04-11 20:02 八进制

把ErrorViewPart所在的plugin加到rcp的运行plugins里应该就可以了吧。这个viewpart是属于org.eclipse.ui.internal包的，也许本身就在rcp里，那么只要用一个action把它显示出来即可，找找eclipse里的那个action。

我最近在写一个rcp应用的时候为了同步保持一个插件版本，将eclise.IDE下的IDExxxxBuilder的代码copy到actionbaradvitor里面了，通过这个可以重建整个IDE的基本环境，对于应用部分来说，就可以忽略RCP平台和Eclpse IDE环境的差异了。

有个别差异的地方，通过一个abstractfactory简单的封装了，现在看来，效果还不错。。。

您好！我现在也在做一个RCP项目。想做成ECLPSE的PLUGIN一样的效果。一个插件放到ECLIPSE的目录中，然后ECLIPSE -CLEAN即可见到插件。不知道能不能在RCP中是否能实现此效果。。。还是只有选择OSGI为底层才能实现此效果。。。。。。如有想法能不能给我发邮件：cary@dsrcom.com。谢谢！

想冒昧地请教一个问题：rcp打包成独立的可运行文件，总是不成功。　　在eclipse中，包括在打包文件（xml,product）中都可以很好地运行

。但是导出后，主程序一运行，就出错。
程序中使用了spring,hibernate，所以全打包进去了。

以下是plugin.xml中的选择情况：
1>
depencies中　
<import plugin="org.eclipse.core.runtime"/>
<import plugin="org.eclipse.ui"/>
<import plugin="org.eclipse.ui.intro"/>

2>

加入了:
. 和

customization.ini

plugin.xml

以上是我发表的请教问题，但我实在是。。。。搞不懂，也不舒服。
凌晨5　点起床，忙到7点。
基本解决。
不能肯定哪里出问题，不过，打包的方法，基本上知道。只是解释不出原因。

有一个现象就是：　build 中的extra classpath entries中，不能加任何内容。一加项目前就有一个大大的红叉。
只有去掉。
