很多人在開發(fā)RCP時，發(fā)現(xiàn)開發(fā)時都沒問題，但導出成包時卻報找不到第三方庫中類的錯誤。主要原因就是沒有將第三方庫配置好。現(xiàn)在我給出一個實現(xiàn)項目的配置為示例，以供參考。 原文出處:http://www.eclipseworld.org/bbs/read.php?tid=1133 環(huán)境：Eclipse3.2M3 一個RCP的實際項目
一、
最關鍵的就是plugin.xml和MANIFEST.MF 所有界面上的最后操作，結果都是保存在這兩個文件中。注意：“.classpath”文件只是開發(fā)時對引用第三庫有用，打包發(fā)行之后它的作用就沒有了，還得靠plugin.xml和MANIFEST.MF。
1、plugin.xml文件
<?xml version="1.0" encoding="GB2312"?>

2、
META-INF\MANIFEST.MF文件
??? 注意：（1）這里require-bundle定義了項目依賴的插件。
（2）Bundle-ClassPath定義了引用的第三方庫，別忘了把AdminConolse項目自己console.jar加進去，否則連自己項目里的類都會找不到。
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/xerces-2.6.2.jar,
?lib/xmlParserAPIs-2.2.1.jar,
?lib/xmlrpc-2.0.jar
?3、build.properties文件。
這個文件主要是用Eclipse導出包的時候用。
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，這個放一些上面幾個文件用到的變量。
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\
