currently I have build an application using eclipse RCP. The application can create multiple products, save them in an XML file, and the file is loaded inside the application and displayed inside a table. I have used JAXB to marshall and unmarshall the XML-file.
目前我已经使用eclipse RCP构建了一个应用程序。应用程序可以创建多个产品,将它们保存在XML文件中,文件将加载到应用程序中并显示在表中。我使用JAXB来编组和解组XML文件。
the current problem occurs when I want to deploy or export the application. After explorting the application in the log file I get this error:
当我想部署或导出应用程序时,会出现当前问题。在日志文件中探索应用程序后,我收到此错误:

I did not really find a helpul answer on the internet.
我没有在网上找到帮助答案。
I can only assure you that I have included the 3 JAR files (jaxb-api, jaxb-core, jaxb-impl) of JAXB for the deployment inside the manifest of the plugin.
我只能向您保证,我已将JAXB的3个JAR文件(jaxb-api,jaxb-core,jaxb-impl)包含在插件清单中的部署中。
Bundle-ClassPath: .,

appdata/,
lib/log4j.jar,
lib/jaxb-2.2.11/jaxb-api.jar,
lib/jaxb-2.2.11/jaxb-impl.jar,

lib/jaxb-2.2.11/jaxb-xjc.jar
Bundle-RequiredExecutionEnvironment: JavaSE-1.7

Can you please advice me what I can do to solve the problem.
能否请您告诉我如何解决问题。

I'm also using JAXB in one of my app (JMSToolBox) and I didn't do anything specific for the application (one product + multiple plugins) to work.
I didn't add extra libraries to neither the plugin or product or manifest as you did.
JMSToolBox runs on JDK 7 with eclipse v4.5.2 and JAXB classes (ie javax.xml.bind.* classes) are included within the JRE that I bundle (the JRE) with the application, specifically Oracle/Sun JRE v1.7.0.80 Does your application runs well inside eclipse, ie when started from the eclipse worbench or do you have this problem only when you build/export the application?
我也在我的一个应用程序(JMSToolBox)中使用JAXB,我没有做任何特定的应用程序(一个产品+多个插件)工作。我没有像你那样为插件,产品或清单添加额外的库。 JMSToolBox在JDK 7上运行,带有eclipse v4.5.2和JAXB类(即javax.xml.bind。* classes)包含在我与应用程序捆绑(JRE)的JRE中,特别是Oracle / Sun JRE v1.7.0.80你的应用程序是否在eclipse中运行良好,即从eclipse worbench启动时,或者只有在构建/导出应用程序时才遇到此问题?
