這種異常僅在第一次調用時發生。
這個問題已經引起這裏： Appengine java - Jersey/Jackson JaxbAnnotationIntrospector NoClassDefFoundError
我嘗試申請推薦的解決方案和傑克遜-XC庫添加到我的項目。 但我仍然有例外。
我加入了使用maven庫：
<dependency>
<groupId>org.codehaus.jackson</groupId>
<artifactId>jackson-xc</artifactId>
<version>1.9.12</version>
</dependency>
任何人知道如何實施解決方案或有其他解決方案？
我有同樣的問題也請把你的答案，如果你看着辦吧 – MobileMon 2013-04-09 12:56:45
你是怎麼解決這個問題？我只有在第一次通話時纔會這樣。 – Guus 2013-09-06 09:02:45
