很多人在开发RCP时，发现开发时都没问题，但导出成包时却报找不到第三方库中类的错误。主要原因就是没有将第三方库配置好。现在我给出一个实现项目的配置为示例，以供参考。
环境：Eclipse3.2M3 一个RCP的实际项目，插件项目同样适用此方法
一、最关键的就是plugin.xml和MANIFEST.MF
所有界面上的最后操作，结果都是保存在这两个文件中。注意：“.classpath”文件只是开发时对引用第三库有用，打包发行之后它的作用就没有了，还得靠plugin.xml和MANIFEST.MF。
1、plugin.xml文件
id="AdminConsole"
point="org.eclipse.core.runtime.applications">
point="org.eclipse.ui.perspectives">
class="com.wxxr.management.admin.console.monitor.MonitorPerspective"
name="%perspectiveName"
id="com.wxxr.management.admin.console.monitor.MonitorPerspective"/>
class="com.wxxr.management.admin.console.configure.ConfigurePerspective"
name="%configurePerspectiveName"
id="com.wxxr.management.admin.console.configure.ConfigurePerspective"/>
class="com.wxxr.management.admin.console.jmx.JMXPerspective"
name="%jmxPerspectiveName"
id="com.wxxr.management.admin.console.jmx.JMXPerspective"/>
point="org.eclipse.ui.editors">
name="事件列表"
icon="icons/alt16.gif"
class="com.wxxr.management.admin.console.log.ui.LogEditor"
id="com.wxxr.management.admin.console.log.ui.LogEditor">
name="地图"
icon="icons/map_view.gif"
class="com.wxxr.management.admin.console.map.MapEditor"
id="com.wxxr.management.admin.console.map.MapEditor">
point="org.eclipse.ui.views">
id="com.wxxr.management.admin.console.monitor.view"
name="%views.category.name"/>
id="com.wxxr.management.admin.console.navigator.ui.StationExploreView"
name="工作站"
icon="icons/eclipse.gif"
class="com.wxxr.management.admin.console.navigator.ui.StationExploreView"
category="com.wxxr.management.admin.console.monitor.view"/>
name="事件细节"
icon="icons/eclipse.gif"
category="com.wxxr.management.admin.console.monitor.view"
class="com.wxxr.management.admin.console.monitor.eventview.EventDetailView"
id="com.wxxr.management.admin.console.monitor.eventview.EventDetailView" />
name="事件统计"
icon="icons/eclipse.gif"
category="com.wxxr.management.admin.console.monitor.view"
class="com.wxxr.management.admin.console.monitor.view.SystemEventStatisticsView"
id="com.wxxr.management.admin.console.monitor.view.SystemEventStatisticsView" />
name="紧急事件处理"
icon="icons/eclipse.gif"
category="com.wxxr.management.admin.console.monitor.view"
class="com.wxxr.management.admin.console.emergency.ui.EmergencyEventReceiverView"
id="com.wxxr.management.admin.console.emergency.ui.EmergencyEventReceiverView" />
id="com.wxxr.management.admin.console.jmx.view"
name="%views.category.name"/>
name="JMX Connections"
icon="icons/eclipse.gif"
category="com.wxxr.management.admin.console.jmx.view"
class="com.wxxr.management.admin.console.jmx.ui.JMXExploreView"
id="com.wxxr.management.admin.console.jmx.ui.JMXExploreView" />
name="JMX Attributes View"
icon="icons/eclipse.gif"
category="com.wxxr.management.admin.console.jmx.view"
class="com.wxxr.management.admin.console.jmx.ui.AttributesView"
id="com.wxxr.management.admin.console.jmx.ui.AttributesView" />
name="JMX Operations View"
icon="icons/eclipse.gif"
category="com.wxxr.management.admin.console.jmx.view"
class="com.wxxr.management.admin.console.jmx.ui.OperationsView"
id="com.wxxr.management.admin.console.jmx.ui.OperationsView" />
name="JMX MBean View"
icon="icons/eclipse.gif"
category="com.wxxr.management.admin.console.jmx.view"
class="com.wxxr.management.admin.console.jmx.ui.MBeanView"
id="com.wxxr.management.admin.console.jmx.ui.MBeanView" />
id="AdminConsole"
point="org.eclipse.core.runtime.products">
application="com.wxxr.management.admin.console.AdminConsole"
name="AdminConsole"/>
2、META-INF\MANIFEST.MF文件
注意：
（1）这里require-bundle定义了项目依赖的插件。
（2）Bundle-ClassPath定义了引用的第三方库，别忘了把AdminConolse项目自己console.jar加进去，否则连自己项目里的类都会找不到。
Manifest-Version: 1.0
Bundle-ManifestVersion: 2
Bundle-Name: %pluginName
Bundle-SymbolicName: com.wxxr.management.admin.console; singleton:=true
Bundle-Version: 1.0.0
Bundle-Activator: com.wxxr.management.admin.console.AdminConsolePlugin
Bundle-Localization: plugin
Require-Bundle: org.eclipse.ui,
org.eclipse.core.runtime,
org.eclipse.core.resources,
org.eclipse.gef,
org.eclipse.ui.forms,
org.eclipse.ui.console
Eclipse-AutoStart: true
Bundle-Vendor: %providerName
Bundle-ClassPath: console.jar,
lib/commons-codec-1.3.jar,
lib/jboss.jar,
lib/jbossall-client.jar,
lib/jboss-jmx.jar,
lib/jboss-system.jar,
lib/log4j-1.2.8.jar,
lib/wxxr-common-1.0-b1.jar,
lib/wxxr-common-jboss-1.0-b1.jar,
lib/wxxr-db-persistence-1.0-b1.jar,
lib/wxxr-jboss-controller-1.0-b1.jar,
lib/wxxr-jboss-workstation-1.0-b1.jar,
lib/wxxr-remoting-1.0-b1.jar,
lib/wxxr-security-1.0-b1.jar,
lib/xerces-2.6.2.jar,
lib/xmlParserAPIs-2.2.1.jar,
lib/xmlrpc-2.0.jar
3、build.properties文件。这个文件主要是用Eclipse导出包的时候用。
source.console.jar = src/
output.console.jar = bin/
bin.includes = plugin.xml,\
*.jar,\
console.jar, \
plugin.properties
pluginName = Admin Console Plug-in
providerName = WXXR.com.cn
perspectiveName = Admin Console
configurePerspectiveName= Configure
jmxPerspectiveName= JMX Console
jars.extra.classpath = lib/commons-codec-1.3.jar,\
lib/jboss.jar,\
lib/jbossall-client.jar,\
lib/jboss-jmx.jar,\
lib/jboss-system.jar,\
lib/log4j-1.2.8.jar,\
lib/wxxr-common-1.0-b1.jar,\
lib/wxxr-common-jboss-1.0-b1.jar,\
lib/wxxr-db-persistence-1.0-b1.jar,\
lib/wxxr-jboss-controller-1.0-b1.jar,\
lib/wxxr-jboss-workstation-1.0-b1.jar,\
lib/wxxr-security-1.0-b1.jar,\
lib/wxxr-remoting-1.0-b1.jar,\
lib/xerces-2.6.2.jar,\
lib/xmlParserAPIs-2.2.1.jar,\
lib/xmlrpc-2.0.jar
4、plugin.properties，这个放一些上面几个文件用到的变量。
pluginName= WXXR Admin Console
providerName= wxxr.com.cn
productName= WXXR SMS Operation Platform
appName= WXXR Admin Console
perspectives.browser.name= WXXR Admin Console
views.category.name= WXXR Admin Console
views.browser.name= Browser
views.history.name= History
views.stationexplore.name= Stations
views.tasklist.name= Task List
views.loglist.name= Workstation Monitor
monitor.message.detail=Monitor Message Detail
monitor.message.statistics=????
swtAppName= AdminConsole
aboutText= WXXR Admin Console \n\n\

二、图形方式
有时直接编辑plugin.xml等文件容易出错（全角空格什么的），那么可以用图形编辑方式来，不过最后结果还是反映到plugin.xml等文件中的。我把plugin.xml打开，然后一个项一个项的把图截下来，以供大家参考。
这个界面是build.properties配置的反映
最好在项目属性的库用引项的效果如下：
