使用基于OSGi的开源平台开发APP，用Karaf做容器，使用一个第三方库时报错。

[computerma]

基本情况介绍：开发使用的平台是基于OSGi的，运行在Karaf里。现在要使用一个第三方的bundle（JAR包），

Karaf加载这个JAR包时是没问题的：

你这个问题很偏啊 ，玩osgi的不多 不是bundle加载出的问题。出问题的是找不到： javax/xml/parsers/DocumentBuilderFactory 这个是javax的类，包含rt.jar，你应该采用系统扩展库的方式加载的方式加载 felix是把配置文件中的 #org.osgi.framework.bootdelegation=sun.*,com.sun.* 注释去掉，增加需要引入的包名称 看了一下karaf的配置，在这个下面

org.osgi.framework.bootdelegation = \
    com.sun.*, \
    javax.transaction, \
    javax.transaction.*, \
    javax.xml.crypto, \
    javax.xml.crypto.*, \

没有加载 javax.xml.parsers 而是使用了外部的 javax.xml.parsers

org.osgi.framework.system.packages.extra = \

javax.xml.parsers;uses:=\"javax.xml.validation,org.w3c.dom,org.xml.sax,org.xml.sax.helpers\";version=1.4, \

你可以在org.osgi.framework.bootdelegation = \ 下增加 javax.xml.parsers。看看和外部 javax.xml.parsers是否冲突

你好。这个问题也折腾了很久。基本解决了，只剩下这一个，跟之前发帖的比较类似： 2015-12-15 22:27:52,312 | ERROR | l for user karaf | ShellUtil | 25 - org.apache.karaf.shell.console - 3.0.4 | Exception caught while executing command java.lang.NoClassDefFoundError: com/google/common/base/MoreObjects at org.onosproject.xuanwulake.service.Policy.toString(Policy.java:133) at org.onosproject.xuanwulake.cli.CShowPolicyCmd.execute(CShowPolicyCmd.java:26) at org.onosproject.cli.AbstractShellCommand.doExecute(AbstractShellCommand.java:129) at org.apache.karaf.shell.console.AbstractAction.execute(AbstractAction.java:33) at org.apache.karaf.shell.commands.basic.AbstractCommand.execute(AbstractCommand.java:33) at Proxy588c04cf_a846_4d01_8593_96980eefb543.execute(Unknown Source) at Proxy588c04cf_a846_4d01_8593_96980eefb543.execute(Unknown Source) at org.apache.felix.gogo.runtime.CommandProxy.execute(CommandProxy.java:78) at org.apache.felix.gogo.runtime.Closure.executeCmd(Closure.java:480) at org.apache.felix.gogo.runtime.Closure.executeStatement(Closure.java:406) at org.apache.felix.gogo.runtime.Pipe.run(Pipe.java:108) at org.apache.felix.gogo.runtime.Closure.execute(Closure.java:182) at org.apache.felix.gogo.runtime.Closure.execute(Closure.java:119) at org.apache.felix.gogo.runtime.CommandSessionImpl.execute(CommandSessionImpl.java:94) at org.apache.karaf.shell.console.impl.jline.ConsoleImpl.run(ConsoleImpl.java:208) at org.apache.karaf.shell.console.impl.jline.LocalConsoleManager$2$1$1.run(LocalConsoleManager.java:109) at java.security.AccessController.doPrivileged(Native Method)[:1.8.0_66] at org.apache.karaf.jaas.modules.JaasHelper.doAs(JaasHelper.java:57)[26:org.apache.karaf.jaas.modules:3.0.4] at org.apache.karaf.shell.console.impl.jline.LocalConsoleManager$2$1.run(LocalConsoleManager.java:102)[25:org.apache.karaf.shell.console:3.0.4] Caused by: java.lang.ClassNotFoundException: com.google.common.base.MoreObjects not found by org.onosproject.onos-app-xuanwulake [176] at org.apache.felix.framework.BundleWiringImpl.findClassOrResourceByDelegation(BundleWiringImpl.java:1532) at org.apache.felix.framework.BundleWiringImpl.access$400(BundleWiringImpl.java:75) at org.apache.felix.framework.BundleWiringImpl$BundleClassLoader.loadClass(BundleWiringImpl.java:1955) at java.lang.ClassLoader.loadClass(ClassLoader.java:357)[:1.8.0_66] ... 19 more 我试着通过修改Karaf的config.properties中的org.osgi.framework.bootdelegation来解决这个问题，但试了很多遍都不行。

[dracularking]

加这个org.osgi.framework.bootdelegation估计也不能自动找到 如果是类似的，不是和之前一样解决么

[tianfang]

<dependency> <groupId>com.google.guava</groupId> <artifactId>guava</artifactId> <version>17.0</version> </dependency> 是一个bundle， com.google .common.base包含在其中 。看看ShellUtil 是否导入了这个bundle

[tianfang]

com/google/common/base/MoreObjects这个类是两个月前加入的 上面贴子中的17.0版本是没有的 18.0之后才有，最好是12月发布的19.0版

[computerma]

问题最终解决了。不过是2015年12月的事情了，java.lang.NoClassDefFoundError: com/google/common/base/MoreObjects 项目使用MoreObjects是用它来记录log的，使用的地方也不是很多。印象中应该是直接用Java自身的System.out.println来规避这个问题的。
